在Android的ImageView中添加gif图像

我在imageView中添加了动画gif图像。我无法将其查看为gif图像。那里没有动画。它看起来像是静止图像。我想知道如何将其显示为gif图像。

首先，将您的GIF图片复制到应用程序的Asset文件夹中，创建以下类并粘贴代码 AnimationActivity：-

public class AnimationActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    InputStream stream = null;
    try {
        stream = getAssets().open("piggy.gif");
    } catch (IOException e) {
        e.printStackTrace();
    }
          GifWebView view = new GifWebView(this, "file:///android_asset    /piggy.gif");                 

    setContentView(view);
}
}

GifDecoder：-

public class GifDecoder {

    public static final int STATUS_OK = 0;

    public static final int STATUS_FORMAT_ERROR = 1;

    public static final int STATUS_OPEN_ERROR = 2;

    protected static final int MAX_STACK_SIZE = 4096;
    protected InputStream in;
    protected int status;
    protected int width; // full image width
    protected int height; // full image height
    protected boolean gctFlag; // global color table used
    protected int gctSize; // size of global color table
    protected int loopCount = 1; // iterations; 0 = repeat forever
    protected int[] gct; // global color table
    protected int[] lct; // local color table
    protected int[] act; // active color table
    protected int bgIndex; // background color index
    protected int bgColor; // background color
    protected int lastBgColor; // previous bg color
    protected int pixelAspect; // pixel aspect ratio
    protected boolean lctFlag; // local color table flag
    protected boolean interlace; // interlace flag

    protected int ix, iy, iw, ih; // current image rectangle

    protected Bitmap image; // current frame
    protected Bitmap lastBitmap; // previous frame
    protected byte[] block = new byte[256]; // current data block
    protected int blockSize = 0; // block size last graphic control extension info
    protected int dispose = 0; // 0=no action; 1=leave in place; 2=restore to bg; 3=restore to prev
    protected int lastDispose = 0;
    protected boolean transparency = false; // use transparent color
    protected int delay = 0; // delay in milliseconds
    protected int transIndex; // transparent color index
    // LZW decoder working arrays
    protected short[] prefix;
    protected byte[] suffix;
    protected byte[] pixelStack;
    protected byte[] pixels;
    protected Vector<GifFrame> frames; // frames read from current file
    protected int frameCount;

    private static class GifFrame {
            public GifFrame(Bitmap im, int del) {
                    image = im;
                    delay = del;
            }

            public Bitmap image;
            public int delay;
    }


    public int getDelay(int n) {
            delay = -1;

                            } else {

private GifDecoder mGifDecoder;

private Bitmap mTmpBitmap;

final Handler mHandler = new Handler();

final Runnable mUpdateResults = new Runnable() {
    public void run() {
        if (mTmpBitmap != null && !mTmpBitmap.isRecycled()) {
            GifDecoderView.this.setImageBitmap(mTmpBitmap);
        }
    }
};

public GifDecoderView(Context context, InputStream stream) {
    super(context);
    playGif(stream);
}

private void playGif(InputStream stream) {
    mGifDecoder = new GifDecoder();
    mGifDecoder.read(stream);

    mIsPlayingGif = true;

    new Thread(new Runnable() {
        public void run() {

}

@Override
protected void onDraw(Canvas canvas) {
    canvas.drawColor(Color.TRANSPARENT);
    super.onDraw(canvas);
    final long now = SystemClock.uptimeMillis();

    if (mMoviestart == 0) { 
        mMoviestart = now;
    }

    final int relTime = (int)((now - mMoviestart) % mMovie.duration());
    mMovie.setTime(relTime);
    mMovie.draw(canvas, 10, 10);
    this.invalidate();
}
}

GifWebView：-

public class GifWebView extends WebView {

public GifWebView(Context context, String path) {
    super(context);        

    loadUrl(path);
}
}

我认为这可能会帮助您... :)

在您的build.gradle（Module：app）中，android-gif-drawable通过添加以下代码将其添加为依赖项：

allprojects {
    repositories {
       mavenCentral()
    }
}

dependencies {
    compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.+'
}

dependencies {
    implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.17'
}

然后同步您的项目。同步结束后，转到布局文件并添加以下代码：

<pl.droidsonroids.gif.GifImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/gif_file"
/>

就是这样，您可以使用简单的ImageView对其进行管理。

使用VideoView。

本机ImageView不支持动画图像。您有两个选项可以显示动画gif文件

1. 用 VideoView
2. 使用ImageViewgif文件并将其拆分为几个部分，然后对其应用动画

带有最新的Glide库

使用Gradle：

repositories {
  mavenCentral()
  google()
}

dependencies {
  implementation 'com.github.bumptech.glide:glide:4.8.0'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'
}

活动或片段：

ImageView imageView = findViewById(R.id.imageView);

/* from internet*/
Glide.with(this)
        .load("https://media.giphy.com/media/98uBZTzlXMhkk/giphy.gif")
        .into(imageView);

/*from raw folder*/
Glide.with(this)
        .load(R.raw.giphy)
        .into(imageView);

在Android中显示GIF

创造 CustomGifView.java which extends View Class

 public class CustomGifView extends View {

 private InputStream gifInputStream;
 private Movie gifMovie;
 private int movieWidth, movieHeight;
 private long movieDuration;
 private long mMovieStart;

 public CustomGifView(Context context) {
  super(context);
  init(context);
 }

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

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

 private void init(Context context){
  setFocusable(true);
  gifInputStream = context.getResources()
    .openRawResource(R.drawable.YOUR_IMAGE);

  gifMovie = Movie.decodeStream(gifInputStream);
  movieWidth = gifMovie.width();
  movieHeight = gifMovie.height();
  movieDuration = gifMovie.duration();
 }

 @Override
 protected void onMeasure(int widthMeasureSpec, 
   int heightMeasureSpec) {
  setMeasuredDimension(movieWidth, movieHeight);
 }

 public int getMovieWidth(){
  return movieWidth;
 }

 public int getMovieHeight(){
  return movieHeight;
 }

 public long getMovieDuration(){
  return movieDuration;
 }

 @Override
 protected void onDraw(Canvas canvas) {

  long now = android.os.SystemClock.uptimeMillis();
        if (mMovieStart == 0) {   // first time
            mMovieStart = now;
        }

        if (gifMovie != null) {

            int dur = gifMovie.duration();
            if (dur == 0) {
                dur = 1000;
            }

            int relTime = (int)((now - mMovieStart) % dur);

            gifMovie.setTime(relTime);

            gifMovie.draw(canvas, 0, 0);
            invalidate();

        }

 }

 }

现在在您的XML中调用此类

 <Your_PackageName.CustomGifView
        android:id="@+id/gifview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

NP

修改AndroidManifest.xml以关闭hardwareAccelerated。

 android:hardwareAccelerated="false"

另一个技巧

有关动画功能，您可以访问

http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html

我建议您使用Glide库。要使用Glide，您需要添加它以添加这些依赖项

compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:support-v4:23.4.0'

到您的grandle（Module：app）文件。

然后使用此行代码加载您的gif图像

Glide.with(context).load(R.drawable.loading).asGif().diskCacheStrategy(DiskCacheStrategy.SOURCE).crossFade().into(loadingImageView);

基于Ahmad Dwaik'Warlock的评论，我尝试了以下代码，并且该代码有效。

1. 在xml文件中使用Webview，并将其位置调整为您正试图向您显示.gif图像的位置。
2. 在您的活动中，像其他视图一样初始化这一小幅Web视图。
3. 将.gif图片放置在素材资源文件夹中
4. 现在加载图像，就像您将URL加载到Webview中一样，例如“ diyaWebView1.loadUrl（“ file：///android_asset/www/diya.gif”）;“
5. 启动应用程序时，您可以看到.gif图像。

PS：如果您的.gif图像适合您的Web视图，则此方法有效；反之亦然；如果图像大于Web视图，则启用滚动条，并且用户可以滚动图像AKA Web视图。因此，在使用此功能时，我们需要小心谨慎，以便根据图像为网络视图提供适当的尺寸，或编辑适合您网络视图的图像。

使用Webview加载gif如下

webView = (WebView) findViewById(R.id.webView);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("file:///android_asset/1.gif");

GIFImageView

public class GifImageView extends ImageView {

    Movie movie;
    InputStream inputStream;
    private long mMovieStart;

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

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

    public GifImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
        setFocusable(true);
        inputStream = context.getResources()
                .openRawResource(R.drawable.thunder);
            byte[] array = streamToBytes(inputStream);
            movie = Movie.decodeByteArray(array, 0, array.length);

    }

    private byte[] streamToBytes(InputStream is) {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(
                1024);
        byte[] buffer = new byte[1024];
        int len;
        try {
            while ((len = is.read(buffer)) >= 0) {
                byteArrayOutputStream.write(buffer, 0, len);
                return byteArrayOutputStream.toByteArray();
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        return null;
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        long now = SystemClock.uptimeMillis();
        if (mMovieStart == 0) { // first time
            mMovieStart = now;
        }
        if (movie != null) {
            int dur = movie.duration();
            if (dur == 0) {
                dur = 3000;
            }
            int relTime = (int) ((now - mMovieStart) % dur);
            movie.setTime(relTime);
            movie.draw(canvas, getWidth() - 200, getHeight() - 200);
            invalidate();
        }
    }

}

在XML中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <TextView
        android:id="@+id/update"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="abc" /> 

    <com.example.apptracker.GifImageView
        android:id="@+id/gifImageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" />

</RelativeLayout>

在Java文件中

public class MainActivity extends Activity {
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); 
        GifImageView gifImageView = (GifImageView) findViewById(R.id.gifImageView1);
        if (Build.VERSION.SDK_INT >= 11) {
            gifImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
        }
    }
}

gifImageView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);当启用硬件加速时，我们需要使用GIF图像在这些设备上不起作用。在（4.x）以上版本的设备上启用了硬件加速。

正如@Ahmad在评论中所说，您可以只使用以下代码显示gif！

只需在onCreate方法中弹出此代码，就可以了！另外，将gif放在assets文件夹中（如果没有素材资源文件夹，请在下创建一个src/main）

WebView wView = new WebView(this);
wView.loadUrl("file:///android_asset/piggy.gif");
setContentView(view);

我们可以使用离子库轻松在imageview上添加动画gif图像。

教程视频:: https://www.youtube.com/watch?v=IqKtpdeIpjA

ImageView image = (ImageView)findViewById(R.id.image_gif);
Ion.with(image).load("http://mygifimage.gif");

这对我有用：

在您的build.gradle（项目）中，在buildscript {}和allprojects {}中编写mavenCentral（）。它看起来应该像这样：

buildscript {
    repositories {
        jcenter()
        **mavenCentral()**
    }
//more code ...
}
allprojects {
    repositories {
        jcenter()
        **mavenCentral()**
    }
}

然后，在build.gradle（module）中添加依赖项{}，此代码段：

编译'pl.droidsonroids.gif：android-gif-drawable：1.2.4'

它应该看起来像这样：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.0'
    testCompile 'junit:junit:4.12'
    **compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.4'**
}

将.gif图像放入可绘制文件夹中。现在转到应用程序> res>布局> activity_main.xml并将其添加为您的.gif：

<pl.droidsonroids.gif.GifImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/YOUR_GIF_IMAGE"
    android:background="#000000" //for black background
    />

您完成了:)

希望这可以帮助。

您可以通过Facebook的Fresco库显示任何gif图像：

Uri uri = Uri.parse("http://domain.com/awersome.gif");
final SimpleDraweeView draweeView = new SimpleDraweeView(context);
final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(200, 200);

draweeView.setLayoutParams(params);
DraweeController controller = Fresco.newDraweeControllerBuilder()
        .setUri(uri)
        .setAutoPlayAnimations(true)
        .build();
draweeView.setController(controller);
//now just add draweeView to layout and enjoy

首先在module:appbuild.gradle文件中添加一个依赖项

compile 'pl.droidsonroids.gif:android-gif-drawable:1.1.+'

然后，在布局文件中

<pl.droidsonroids.gif.GifImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/mq_app"
        />

Gif也可以通过几行代码在Web视图中显示，并且没有任何第三方库。这样，您甚至可以从SD卡加载gif。无需将图像复制到资产文件夹。

进行网络查看。

<WebView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/imageWebView" />

如许多示例所示，使用不仅可以从资产文件夹中打开SD卡中的gif文件。

    WebView webView = (WebView) findViewById(R.id.imageWebView);
    String  data    = "<body> <img src = \""+ filePath+"\"/></body>";
    // 'filePath' is the path of your .GIF file on SD card.
   webView.loadDataWithBaseURL("file:///android_asset/",data,"text/html","UTF-8",null);

我遇到使用困难

compile 'pl.droidsonroids.gif:android-gif-drawable:1.1.+'

而且我也找不到要添加到我的项目中的jar文件。因此，为了显示gif，我使用WebView像这样：

WebView webView = (WebView) this.findViewById(R.id.webView);
webView.loadDataWithBaseURL(null, "<html><body><center><img style='align:center;width:250px; height:250px; border-radius:50%' src='file:///android_asset/loading.gif'/></center></body></html>", "text/html", "UTF-8", "");
webView.setBackgroundColor(Color.TRANSPARENT);

在Android中显示GIF文件

在build.gradle文件中添加以下依赖项。

implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.0'

在布局- activity_xxxxx.xml文件中，添加GifImageview以下内容。

<pl.droidsonroids.gif.GifImageView
   android:id="@+id/CorrWrong"
   android:layout_width="100dp"
  android:layout_height="75dp"/>

在您的Java文件中，您可以按以下方式访问gif。

 GifImageView emoji;
 emoji = (GifImageView)findViewById(R.id.CorrWrong);

import android.app.Activity;
import android.util.Log;
import android.widget.ImageView;
