Android如何在可见软键盘时在全屏模式下调整布局

当软键盘处于活动状态时，我已经进行了很多研究来调整布局，并且我已经成功实现了它，但是当我android:theme="@android:style/Theme.NoTitleBar.Fullscreen"在清单文件中的活动标签中使用它时，问题就来了。

为此，我使用android:windowSoftInputMode="adjustPan|adjustResize|stateHidden"了其他选项，但没有运气。

之后，我以FullScreen编程方式实施并尝试使用各种布局，FullScreen但徒劳无功。

我引用了这些链接，并在此处查找了许多与此问题相关的帖子：

我希望当软键盘进入图片时，底部的2个按钮应向上移动。

基于yghm的变通方法，我编写了一个便捷类，该类使我可以单线解决问题（当然，在将新类添加到我的源代码之后）。单线是：

     AndroidBug5497Workaround.assistActivity(this);

实现类是：

public class AndroidBug5497Workaround {

    // For more information, see https://issuetracker.google.com/issues/36911528
    // To use this class, simply invoke assistActivity() on an Activity that already has its content view set.

    public static void assistActivity (Activity activity) {
        new AndroidBug5497Workaround(activity);
    }

    private View mChildOfContent;
    private int usableHeightPrevious;
    private FrameLayout.LayoutParams frameLayoutParams;

    private AndroidBug5497Workaround(Activity activity) {
        FrameLayout content = (FrameLayout) activity.findViewById(android.R.id.content);
        mChildOfContent = content.getChildAt(0);
        mChildOfContent.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            public void onGlobalLayout() {
                possiblyResizeChildOfContent();
            }
        });
        frameLayoutParams = (FrameLayout.LayoutParams) mChildOfContent.getLayoutParams();
    }

    private void possiblyResizeChildOfContent() {
        int usableHeightNow = computeUsableHeight();
        if (usableHeightNow != usableHeightPrevious) {
            int usableHeightSansKeyboard = mChildOfContent.getRootView().getHeight();
            int heightDifference = usableHeightSansKeyboard - usableHeightNow;
            if (heightDifference > (usableHeightSansKeyboard/4)) {
                // keyboard probably just became visible
                frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
            } else {
                // keyboard probably just became hidden
                frameLayoutParams.height = usableHeightSansKeyboard;
            }
            mChildOfContent.requestLayout();
            usableHeightPrevious = usableHeightNow;
        }
    }

    private int computeUsableHeight() {
        Rect r = new Rect();
        mChildOfContent.getWindowVisibleDisplayFrame(r);
        return (r.bottom - r.top);
    }
}

希望这对某人有帮助。

由于答案已经被选择并且已知问题是错误，所以我认为我将添加“可能的解决方法”。

显示软键盘时，您可以切换全屏模式。这样可以使“ adjustPan”正常工作。

换句话说，我仍然使用@android：style / Theme.Black.NoTitleBar.Fullscreen作为应用程序主题的一部分，并使用stateVisible | adjustResize作为活动窗口软输入模式的一部分，但是要使它们协同工作，我必须切换全屏模式在键盘启动之前。

使用以下代码：

关闭全屏模式

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

开启全萤幕模式

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);

注意-灵感来自：以全屏模式隐藏标题

我尝试了约瑟夫·约翰逊（Joseph Johnson）的解决方案，但是像其他人一样，我遇到了内容与键盘之间的鸿沟。发生此问题的原因是，在使用全屏模式时，软输入模式始终处于平移状态。当您激活将由软输入隐藏的输入字段时，此平移会干扰Joseph的解决方案。

当出现软输入时，首先根据其原始高度平移内容，然后根据约瑟夫解决方案要求的布局调整其大小。调整大小和后续布局不会取消平移，这会导致间隙。事件的完整顺序是：

1. 全局布局侦听器
2. 平移
3. 内容的布局（=实际调整内容的大小）

无法禁用平移，但是可以通过更改内容的高度将平移偏移强制为0。可以在侦听器中完成此操作，因为它是在平移发生之前运行的。将内容高度设置为可用高度可带来流畅的用户体验，即不会闪烁。

我也做了这些更改。如果其中任何一个引起问题，请告诉我：

• 切换确定可用高度getWindowVisibleDisplayFrame。该Rect缓存，以防止不必要的垃圾一点点。
• 也允许删除侦听器。当您将活动重用于具有不同全屏要求的不同片段时，此功能很有用。
• 不要区分显示的键盘还是隐藏的键盘，但始终将内容高度设置为可见的显示框架高度。

它已在Nexus 5上进行了测试，并且模拟器运行的API级别为16-24，屏幕尺寸从微小到较大。

该代码已被移植到Kotlin，但是将所做的更改移植回Java很简单。让我知道您是否需要帮助：

class AndroidBug5497Workaround constructor(activity: Activity) {
    private val contentContainer = activity.findViewById(android.R.id.content) as ViewGroup
    private val rootView = contentContainer.getChildAt(0)
    private val rootViewLayout = rootView.layoutParams as FrameLayout.LayoutParams
    private val viewTreeObserver = rootView.viewTreeObserver
    private val listener = ViewTreeObserver.OnGlobalLayoutListener { possiblyResizeChildOfContent() }

    private val contentAreaOfWindowBounds = Rect()
    private var usableHeightPrevious = 0

    // I call this in "onResume()" of my fragment
    fun addListener() {
        viewTreeObserver.addOnGlobalLayoutListener(listener)
    }

    // I call this in "onPause()" of my fragment
    fun removeListener() {
        viewTreeObserver.removeOnGlobalLayoutListener(listener)
    }

    private fun possiblyResizeChildOfContent() {
        contentContainer.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds)
        val usableHeightNow = contentAreaOfWindowBounds.height()
        if (usableHeightNow != usableHeightPrevious) {
            rootViewLayout.height = usableHeightNow
            // Change the bounds of the root view to prevent gap between keyboard and content, and top of content positioned above top screen edge.
            rootView.layout(contentAreaOfWindowBounds.left, contentAreaOfWindowBounds.top, contentAreaOfWindowBounds.right, contentAreaOfWindowBounds.bottom)
            rootView.requestLayout()

            usableHeightPrevious = usableHeightNow
        }
    }
}

如果您正在使用系统UI方法（https://developer.android.com/training/system-ui/immersive.html），我只是找到了一个简单可靠的解决方案。

它在您使用的情况下有效View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN，例如，如果您正在使用CoordinatorLayout。

它不适用于WindowManager.LayoutParams.FLAG_FULLSCREEN（您也可以使用设置主题android:windowFullscreen），但是您可以使用实现类似的效果SYSTEM_UI_FLAG_LAYOUT_STABLE（根据docs “具有相同的视觉效果” ），并且该解决方案应该可以再次使用。

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION /* If you want to hide navigation */
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE)

我已经在运行棉花糖的设备上对其进行了测试。

关键是软键盘也是系统窗口之一（例如状态栏和导航栏），因此WindowInsets由系统调度的系统包含有关此准确且可靠的信息。

对于诸如 DrawerLayout试图在状态栏后面绘制，我们可以创建仅忽略顶部插图的布局，并应用底部插图来说明软键盘。

这是我的习惯FrameLayout：

/**
 * Implements an effect similar to {@code android:fitsSystemWindows="true"} on Lollipop or higher,
 * except ignoring the top system window inset. {@code android:fitsSystemWindows="true"} does not
 * and should not be set on this layout.
 */
public class FitsSystemWindowsExceptTopFrameLayout extends FrameLayout {

    public FitsSystemWindowsExceptTopFrameLayout(Context context) {
        super(context);
    }

    public FitsSystemWindowsExceptTopFrameLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public FitsSystemWindowsExceptTopFrameLayout(Context context, AttributeSet attrs,
                                                 int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @RequiresApi(Build.VERSION_CODES.LOLLIPOP)
    public FitsSystemWindowsExceptTopFrameLayout(Context context, AttributeSet attrs,
                                                 int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public WindowInsets onApplyWindowInsets(WindowInsets insets) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            setPadding(insets.getSystemWindowInsetLeft(), 0, insets.getSystemWindowInsetRight(),
                    insets.getSystemWindowInsetBottom());
            return insets.replaceSystemWindowInsets(0, insets.getSystemWindowInsetTop(), 0, 0);
        } else {
            return super.onApplyWindowInsets(insets);
        }
    }
}

并使用它：

<com.example.yourapplication.FitsSystemWindowsExceptTopFrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Your original layout here -->
</com.example.yourapplication.FitsSystemWindowsExceptTopFrameLayout>

从理论上讲，这应该对任何没有疯狂修改的设备都有效，比任何试图以随机1/3或1/4屏幕大小作为参考的黑客都更好。

（它要求使用API​​ 16+，但是我仅在Lollipop +上使用全屏显示状态栏，因此在这种情况下，这是最好的解决方案。）

请注意，为某项活动设置android:windowSoftInputMode="adjustResize"时该功能不起作用WindowManager.LayoutParams.FLAG_FULLSCREEN。您有两个选择。

1. 请为您的活动禁用全屏模式。活动不会在全屏模式下调整大小。您可以在xml中（通过更改活动的主题）或在Java代码中执行此操作。在您的onCreate（）方法中添加以下行。

   getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);   
   getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);`

要么

2. 使用另一种方式来实现全屏模式。在您的onCreate（）方法中添加以下代码。

   getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
   getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
   getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
   View decorView = getWindow().getDecorView();
   // Hide the status bar.
   int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
   decorView.setSystemUiVisibility(uiOptions);`

请注意，method-2仅适用于Android 4.1及更高版本。

我也不得不面对这个问题，并且进行了一些工作，检查了HTC One，S1，S2，S3，银河和HTC的感觉。

将全局布局侦听器放在布局的根视图上

mRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener(){
            public void onGlobalLayout() {
                checkHeightDifference();
            }
    });

然后在那儿我检查了高度差，如果屏幕的高度差更大，则屏幕高度的三分之一，那么我们可以假设键盘是打开的。从这个答案中得到了它。

private void checkHeightDifference(){
    // get screen frame rectangle 
    Rect r = new Rect();
    mRootView.getWindowVisibleDisplayFrame(r);
    // get screen height
    int screenHeight = mRootView.getRootView().getHeight();
    // calculate the height difference
    int heightDifference = screenHeight - (r.bottom - r.top);

    // if height difference is different then the last height difference and
    // is bigger then a third of the screen we can assume the keyboard is open
    if (heightDifference > screenHeight/3 && heightDifference != mLastHeightDifferece) {
        // keyboard visiblevisible
        // get root view layout params
        FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
        // set the root view height to screen height minus the height difference
        lp.height = screenHeight - heightDifference;
        // call request layout so the changes will take affect
        .requestLayout();
        // save the height difference so we will run this code only when a change occurs.
        mLastHeightDifferece = heightDifference;
    } else if (heightDifference != mLastHeightDifferece) {
        // keyboard hidden
        PFLog.d("[ChatroomActivity] checkHeightDifference keyboard hidden");
        // get root view layout params and reset all the changes we have made when the keyboard opened.
        FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) mRootView.getLayoutParams();
        lp.height = screenHeight;
        // call request layout so the changes will take affect
        mRootView.requestLayout();
        // save the height difference so we will run this code only when a change occurs.
        mLastHeightDifferece = heightDifference;
    }
}

这可能不是防弹的，也许在某些设备上将不起作用，但它对我有用，希望对您也有帮助。

我实现了约瑟夫·约翰逊（Joseph Johnson）解决方案，并且运行良好，我注意到使用该解决方案后，有时应用程序上的抽屉无法正确关闭。我添加了一项功能，当用户关闭片段所在的编辑文本时，删除监听器removeOnGlobalLayoutListener。

}

添加android:fitsSystemWindows="true"到布局，此布局将调整大小。

要使其与FullScreen一起使用，请执行以下操作：

使用离子键盘插件。这使您可以侦听键盘的出现和消失时间。

OnDeviceReady添加以下事件侦听器：

// Allow Screen to Move Up when Keyboard is Present
window.addEventListener('native.keyboardshow', onKeyboardShow);
// Reset Screen after Keyboard hides
window.addEventListener('native.keyboardhide', onKeyboardHide);

逻辑：

function onKeyboardShow(e) {
    // Get Focused Element
    var thisElement = $(':focus');
    // Get input size
    var i = thisElement.height();
    // Get Window Height
    var h = $(window).height()
    // Get Keyboard Height
    var kH = e.keyboardHeight
    // Get Focused Element Top Offset
    var eH = thisElement.offset().top;
    // Top of Input should still be visible (30 = Fixed Header)
    var vS = h - kH;
    i = i > vS ? (vS - 30) : i;
    // Get Difference
    var diff = (vS - eH - i);
    if (diff < 0) {
        var parent = $('.myOuter-xs.myOuter-md');
        // Add Padding
        var marginTop = parseInt(parent.css('marginTop')) + diff - 25;
        parent.css('marginTop', marginTop + 'px');
    }
}

function onKeyboardHide(e) {
  // Remove All Style Attributes from Parent Div
  $('.myOuter-xs.myOuter-md').removeAttr('style');
}

基本上，如果它们之间的差为负，那么这就是键盘覆盖输入的像素数量。因此，如果您以此调整父级div，则应该抵消它。

将超时添加到逻辑中表示300ms也应该优化性能（因为这将使键盘时间出现。

我尝试了约瑟夫·约翰逊的课程，虽然有效，但并不能完全满足我的需求。我需要模拟android：windowSoftInputMode =“ adjustPan”，而不是模拟android：windowSoftInputMode =“ adjustResize”。

我正在使用它进行全屏webview。为了将内容视图平移到正确的位置，我需要使用一个javascript接口，该接口提供有关具有焦点的页面元素的位置的详细信息，因此正在接收键盘输入。我已经省略了这些细节，但是提供了对约瑟夫·约翰逊课的重写。这将为您实现自定义平移与调整其大小提供坚实的基础。

                // Keyboard probably just became visible

                // Get the current focus elements top & bottom
                // using a ratio to convert the values
                // to the native scale.

                    int panUpPixels = elPixelsCovered;

                    // Prevent panning so much the top of the element
                    // becomes hidden
                    panUpPixels = ( panUpPixels > elTop ?
                                    elTop : panUpPixels );

                    // Prevent panning more than the keyboard height
                    // (which produces an empty gap in the screen)
                    panUpPixels = ( panUpPixels > coveredHeight ?
                                    coveredHeight : panUpPixels );

                    // Pan up
                    contentView_.setY( -panUpPixels );
                }
            }
            else {
                // Keyboard probably just became hidden

                // Reset pan
                contentView_.setY( 0 );
            }

            // Save usabale height for the next comparison
            priorVisibleHeight_ = currentVisibleHeight;
        }
    }

    private int visibleHeight() {
        Rect r = new Rect();
        contentView_.getWindowVisibleDisplayFrame( r );
        return r.bottom - r.top;
    }

    // Customize this as needed...
    private int viewPortHeight() { return JavaScriptObject.viewPortHeight(); }
    private int focusElementTop( final float ratio ) {
        return (int) (ratio * JavaScriptObject.focusElementTop());
    }
    private int focusElementBottom( final float ratio ) {
        return (int) (ratio * JavaScriptObject.focusElementBottom());
    }

}

实际上，Activity无论windowSoftInputMode我在键盘上选择什么，软键盘的外观似乎都不会以任何方式影响键盘。FullScreen模式下。

尽管我找不到有关此属性的大量文档，但我认为该FullScreen模式是为游戏应用程序设计的，不需要大量使用软键盘。如果您的活动是需要用户通过软键盘进行交互的活动，请重新考虑使用非全屏主题。您可以使用NoTitleBar主题关闭TitleBar 。您为什么要隐藏通知栏？

保持原样android:windowSoftInputMode="adjustResize"。因为它被设置为仅使其中一个不"adjustResize"与"adjustPan"（窗口调整模式是用AdjustResize或AdjustPan指定的。强烈建议您始终指定一个或另一个）。您可以在这里找到它：http : //developer.android.com/resources/articles/on-screen-inputs.html

它非常适合我。

仅android:windowSoftInputMode="adjustResize|stateHidden在使用AdjustPan时使用，然后禁用调整大小属性

我使用约瑟夫·约翰逊（Joseph Johnson）创建的AndroidBug5497Workaround类，但在软键盘和视图之间却留有空白。我引用了此链接Greg Ennis。对上述内容进行一些更改后，这是我的最终工作代码。

我目前正在使用这种方法，它就像一种魅力。诀窍是我们得到键盘高度通过上下21种不同的方法来，然后将其用作活动中根视图的底部填充。我认为您的布局不需要顶部填充（位于状态栏下方），但是如果您需要，请通知我更新答案。

MainActivity.java

public class MainActivity extends AppCompatActivity {
    @Override

                    return insets;

                    decorView.getWindowVisibleDisplayFrame(r);

                    //get screen height and calculate the difference with the useable area from the r
                    int height = decorView.getContext().getResources().getDisplayMetrics().heightPixels;
                    int diff = height - r.bottom;

                    //if it could be a keyboard add the padding to the view
                    if (diff != 0) {
                        // if the use-able screen height differs from the total screen height we assume that it shows a keyboard now
                        //check if the padding is 0 (if yes set the padding for the keyboard)
                        if (contentView.getPaddingBottom() != diff) {
                            //set the padding of the contentView for the keyboard
                            contentView.setPadding(0, 0, 0, diff);
                        }
                    } else {
                        //check if the padding is != 0 (if yes reset the padding)
                        if (contentView.getPaddingBottom() != 0) {
                            //reset the padding of the contentView
                            contentView.setPadding(0, 0, 0, 0);
                        }
                    }
                }
            });
        }
    }
...
}

不要忘记使用id来解决您的根视图：

activity_main.xml

<RelativeLayout

    android:id="@+id/main_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

旧主意

在打开键盘之前创建容器高度的静态值根据usableHeightSansKeyboard - heightDifference键盘打开的时间设置容器高度，并在关闭时将其设置回保存的值

if (heightDifference > (usableHeightSansKeyboard / 4)) {
                // keyboard probably just became visible
                frameLayoutParams.height = usableHeightSansKeyboard - heightDifference;
                int mStatusHeight = getStatusBarHeight();
                frameLayoutParams.topMargin = mStatusHeight;
                ((MainActivity)activity).setMyMainHeight(usableHeightSansKeyboard - heightDifference);

                if(BuildConfig.DEBUG){
                    Log.v("aBug5497", "keyboard probably just became visible");
                }
            } else {
                // keyboard probably just became hidden
                if(usableHeightPrevious != 0) {
                    frameLayoutParams.height = usableHeightSansKeyboard;
                    ((MainActivity)activity).setMyMainHeight();    
                }
                frameLayoutParams.topMargin = 0;

                if(BuildConfig.DEBUG){
                    Log.v("aBug5497", "keyboard probably just became hidden");
                }
            }

MainActivity中的方法

public void setMyMainHeight(final int myMainHeight) {

    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            ConstraintLayout.LayoutParams rLparams =  (ConstraintLayout.LayoutParams) myContainer.getLayoutParams();
            rLparams.height = myMainHeight;

            myContainer.setLayoutParams(rLparams);
        }

    });

}

int mainHeight = 0;
public void setMyMainHeight() {

    runOnUiThread(new Runnable() {
        @Override
        public void run() {
            ConstraintLayout.LayoutParams rLparams =  (ConstraintLayout.LayoutParams) myContainer.getLayoutParams();
            rLparams.height = mainHeight;

            myContainer.setLayoutParams(rLparams);
        }

    });

}

示例容器XML

<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
        <android.support.constraint.ConstraintLayout
            android:id="@+id/my_container"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            app:layout_constraintHeight_percent=".8">

同样，如果需要，可以添加边距...

另一个考虑因素是使用填充，可以在以下位置找到一个示例：

https://github.com/mikepenz/MaterialDrawer/issues/95#issuecomment-80519589

1）创建KeyboardHeightHelper：

public class KeyboardHeightHelper {

    private final View decorView;
    private int lastKeyboardHeight = -1;

    public KeyboardHeightHelper(Activity activity, View activityRootView, OnKeyboardHeightChangeListener listener) {
        this.decorView = activity.getWindow().getDecorView();
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(() -> {
            int keyboardHeight = getKeyboardHeight();
            if (lastKeyboardHeight != keyboardHeight) {
                lastKeyboardHeight = keyboardHeight;
                listener.onKeyboardHeightChange(keyboardHeight);
            }
        });
    }

    private int getKeyboardHeight() {
        Rect rect = new Rect();
        decorView.getWindowVisibleDisplayFrame(rect);
        return decorView.getHeight() - rect.bottom;
    }

    public interface OnKeyboardHeightChangeListener {
        void onKeyboardHeightChange(int keyboardHeight);
    }
}

2）让您的活动全屏显示：

activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

3）聆听键盘高度的变化并为视图添加底部填充：

View rootView = activity.findViewById(R.id.root); // your root view or any other you want to resize
KeyboardHeightHelper effectiveHeightHelper = new KeyboardHeightHelper(
        activity, 
        rootView,
        keyboardHeight -> rootView.setPadding(0, 0, 0, keyboardHeight));

因此，每次键盘出现在屏幕上时-视图底部的填充将更改，并且内容将重新排列。

您希望底部栏保持在视图的底部，但是当显示键盘时，它们应该向上移动以放置在键盘上方，对吗？

您可以尝试以下代码片段：

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    ...>

    <RelativeLayout
        android:id="@+id/RelativeLayoutTopBar"
    ...>
    </RelativeLayout>

    <LinearLayout
        android:id="@+id/LinearLayoutBottomBar"
        android:layout_alignParentBottom = true
        ...>
    </LinearLayout>

    <LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="390dp"
    android:orientation="vertical" 
    android:layout_above="@+id/LinearLayoutBottomBar"
    android:layout_below="@+id/RelativeLayoutTopBar"> 

    <ScrollView 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:layout_marginBottom="10dp"
        android:id="@+id/ScrollViewBackground">

            ...

        </ScrollView>
     </LinearLayout>
  </RelativeLayout>

BottomBar将停留在视图的底部，而包含ScrollView的LinearLayout将在显示顶部/底部栏和键盘之后采用视图的剩余内容。让我知道它是否也适合您。

谢谢约瑟夫的回答。但是，在可能的方法ResizeChildOfContent（）中，该部分

else {
            // keyboard probably just became hidden
            frameLayoutParams.height = usableHeightSansKeyboard;
        }

对我来说不起作用，因为下部的视野被隐藏了。所以我必须使用全局变量restoreHeight，然后在构造函数中插入最后一行

restoreHeight = frameLayoutParams.height;

然后我将前面提到的部分替换为

else {
            // keyboard probably just became hidden
            frameLayoutParams.height = restoreHeight;
        }

但是我不知道为什么您的代码对我不起作用。如果有人可以阐明这一点，那将有很大的帮助。

我只使用全屏模式来隐藏状态栏。但是，我希望在显示键盘时调整应用程序的大小。所有其他解决方案（可能是由于发布时间的原因）都很复杂，或者我无法使用（希望避免更改JavaG代码以免除PhoneGap Build的使用）。

我没有使用全屏，而是将我的Android配置修改为非全屏：

            <preference name="fullscreen" value="false" />

并cordova-plugin-statusbar通过命令行添加：

cordova plugin add cordova-plugin-statusbar

应用加载后，我可以简单地在插件上调用方法来隐藏自身，例如：

    if (window.cordova && window.cordova.platformId == 'android' && window.StatusBar)
        window.StatusBar.hide();

这就像一个魅力。唯一真正的缺点是，在加载应用程序时状态栏会短暂可见。对于我的需求，这不是问题。

我已经尝试了stackOverflow的所有可能答案，终于经过一周的长时间搜索终于解决了。我使用了坐标布局，并使用linearLayout更改了此布局，问题已解决。我不知道坐标布局可能有错误或任何我的错误。

我尝试了许多解决方案，包括约瑟夫·约翰逊（Joseph Johnson）和约翰·斯图伊特（Johan Stuyts）。但是结果是，在所有情况下，某些设备（例如Lenovo s820）在内容和键盘之间都留有空白。因此，我对他们的代码进行了一些更改，终于找到了可行的解决方案。

我的想法基于在显示键盘时在内容顶部增加边距。

contentContainer.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds);
    int usableHeightNow = contentAreaOfWindowBounds.height();

    if (usableHeightNow != usableHeightPrevious) {

        int difference = usableHeightNow - usableHeightPrevious;

        if (difference < 0 && difference < -150) {
            keyboardShowed = true;
            rootViewLayout.topMargin -= difference + 30;
            rootViewLayout.bottomMargin += 30;
        }
        else if (difference < 0 && difference > -150){
            rootViewLayout.topMargin -= difference + 30;
        }
        else if (difference > 0 && difference > 150) {
            keyboardShowed = false;
            rootViewLayout.topMargin = 0;
            rootViewLayout.bottomMargin = 0;
        }

        rootView.requestLayout();

        Log.e("Bug Workaround", "Difference: " + difference);

        usableHeightPrevious = usableHeightNow;
}

如您所见，我将30像素添加到差异中，因为在屏幕顶部和带有边距的内容区域之间有一个小的空白。而且我不知道它出现的位置，所以我决定只是缩小边距，现在它完全可以按照我的需要工作了。

今天，在全屏问题上，adjustResize无法正常工作对于android sdk来说是实际的。

从我发现的答案中：
解决方案 -但是解决方案在图片上显示了此问题：

比我找到解决方案并删除了一项不必要的操作：

this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

因此，请参阅我在Kotlin上的固定解决方案代码：

class AndroidBug5497Workaround constructor(val activity: Activity) {

    private val content = activity.findViewById<View>(android.R.id.content) as FrameLayout

    private val mChildOfContent = content.getChildAt(0)
    private var usableHeightPrevious: Int = 0
    private val contentContainer = activity.findViewById(android.R.id.content) as ViewGroup
    private val rootView = contentContainer.getChildAt(0)
    private val rootViewLayout = rootView.layoutParams as FrameLayout.LayoutParams

    private val listener = {
        possiblyResizeChildOfContent()
    }

    fun addListener() {
        mChildOfContent.apply {
            viewTreeObserver.addOnGlobalLayoutListener(listener)

        }
    }

    fun removeListener() {
        mChildOfContent.apply {
            viewTreeObserver.removeOnGlobalLayoutListener(listener)
        }
    }

    private fun possiblyResizeChildOfContent() {
        val contentAreaOfWindowBounds = Rect()
        mChildOfContent.getWindowVisibleDisplayFrame(contentAreaOfWindowBounds)
        val usableHeightNow = contentAreaOfWindowBounds.height()

        if (usableHeightNow != usableHeightPrevious) {
            rootViewLayout.height = usableHeightNow
            rootView.layout(contentAreaOfWindowBounds.left,
                    contentAreaOfWindowBounds.top, contentAreaOfWindowBounds.right, contentAreaOfWindowBounds.bottom);
            mChildOfContent.requestLayout()
            usableHeightPrevious = usableHeightNow
        }
    }
}

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

    }

    override fun onResume() {
        keyBoardBugWorkaround.addListener()
        super.onResume()
    }

    override fun onPause() {
        keyBoardBugWorkaround.removeListener()
        super.onPause()
    }
}

不要使用：

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

因为效果不好。而不是使用：

fun setFullScreen(fullScreen: Boolean) {
        val decorView = getWindow().getDecorView()
        val uiOptions : Int
        if(fullScreen){
            uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN // this hide statusBar
            toolbar.visibility = View.GONE // if you use toolbar
            tabs.visibility = View.GONE // if you use tabLayout
        } else {
            uiOptions = View.SYSTEM_UI_FLAG_VISIBLE // this show statusBar
            toolbar.visibility = View.VISIBLE
            tabs.visibility = View.VISIBLE
        }
        decorView.setSystemUiVisibility(uiOptions)
    }

就我而言，将Crosswalk添加到Cordova应用程序后，便开始出现此问题。我的应用未在全屏和android：windowSoftInputMode =“ adjustPan”中使用。

我已经在应用程序中安装了离子键盘插件，因此，借助它，可以轻松检测键盘是向上还是向下：

// Listen for events to when the keyboard is opened and closed
window.addEventListener("native.keyboardshow", keyboardUp, false);
window.addEventListener('native.keyboardhide', keyboardDown, false);

function keyboardUp()
{
    $('html').addClass('keyboardUp');
}

function keyboardDown()
{
    $('html').removeClass('keyboardUp');
}

我尝试了上面的所有修复程序，但最终为我完成的操作很简单：

&.keyboardUp {
        overflow-y: scroll;
}

希望这可以节省您我花了几天的时间。:)
