我如何捕获用户单击明文的事件,方法SearchView
是单击右侧的X按钮
我已经捕获了onQueryTextChange
事件,但这是针对所有文本更改的,而不是针对该X按钮的
Answers:
尝试了多种组合之后,我发现了如何捕获SearchView中X按钮后面的事件
以下是onCreateOptionsMenu
我的一个应用程序中的功能的代码段。mSearchMenu
和mSearchView
是全局变量。X实际上是具有ID的ImageView,search_close_btn
文本区域是具有ID的EditText视图search_src_text
@SuppressLint("NewApi")
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.country_list_activity_actions, menu);
mSearchMenu = menu.findItem(R.id.action_search);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
// Get the SearchView and set the searchable configuration
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
mSearchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
// Assumes current activity is the searchable activity
mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
mSearchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default
// Get the search close button image view
ImageView closeButton = (ImageView)mSearchView.findViewById(R.id.search_close_btn);
// Set on click listener
closeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
LoggerUtils.d(LOG, "Search close button clicked");
//Find EditText view
EditText et = (EditText) findViewById(R.id.search_src_text);
//Clear the text from EditText view
et.setText("");
//Clear query
mSearchView.setQuery("", false);
//Collapse the action view
mSearchView.onActionViewCollapsed();
//Collapse the search widget
mSearchMenu.collapseActionView();
}
});
}
// When using the support library, the setOnActionExpandListener() method is
// static and accepts the MenuItem object as an argument
mSearchMenu.setOnActionExpandListener(new OnActionExpandListener() {
@Override
public boolean onMenuItemActionExpand(MenuItem item) {
//Nothing to do here
LoggerUtils.d(LOG, "Search widget expand ");
return true; // Return true to expand action view
}
@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
LoggerUtils.d(LOG, "Search widget colapsed ");
return true; // Return true to collapse action view
}
});
return super.onCreateOptionsMenu(menu);
}
您可以只使用onCloseListener()
sv= (SearchView) findViewById(R.id.searchView1);
sv.setOnCloseListener(new OnCloseListener() {
@Override
public boolean onClose() {
Toast t = Toast.makeText(MainActivity.this, "close", Toast.LENGTH_SHORT);
t.show();
return false;
}
});
SearchView
,但对我而言不起作用iconifiedByDefault="false"
我在尝试通过其ID查找组件时遇到问题,但是我找到了另一种使用相同SearchView上下文搜索该组件的方法
// Catch event on [x] button inside search view
int searchCloseButtonId = searchView.getContext().getResources()
.getIdentifier("android:id/search_close_btn", null, null);
ImageView closeButton = (ImageView) this.searchView.findViewById(searchCloseButtonId);
// Set on click listener
closeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Manage this event.
}
});
searchView.setIconified(true);
或searchView.setIconified(false);

我使用此代码捕获文本查询清除并执行我的操作
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.search, menu);
SearchView searchView = (SearchView) menu.findItem(R.id.search_button).getActionView();
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
SearchView.OnQueryTextListener textChangeListener = new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextChange(String cs) {
if (TextUtils.isEmpty(cs)){
//Text is cleared, do your thing
}
return false;
}
@Override
public boolean onQueryTextSubmit(String query) {
//text query submitted
}
};
searchView.setOnQueryTextListener(textChangeListener);
return true;
}
如果您使用Appcompat库,而不是使用
getResources().getIdentifier("android:id/search_close_btn", null, null);
你可以这样做:
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchItem.getActionView();
View closeButton = searchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn);
closeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//handle click
}
});
编辑2019年8月:
如果您使用androidx: androidx.appcompat.R.id.search_close_btn
ImageView closeButton = (ImageView) this.searchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn);
closeButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Manage this event.
}
});
使用R.id.search_go_btn的“提交”按钮
科特琳回答:
mySearchView.setOnCloseListener(object : SearchView.OnCloseListener {
override fun onClose(): Boolean {
// Do your stuff
return false
}
})
Eduardo的解决方案对我不起作用。我发现了一些对Kotlin有用的东西。我感谢SjoerdvGestel找到了这个解决方案,它的答案是。
// Get the close button on the searchView
val closeButtonId: Int = searching.context.resources.getIdentifier("android:id/search_close_btn", null, null)
val closeButton = searching.findViewById(closeButtonId) as ImageView
// On close collapse the searchView
closeButton.setOnClickListener {
searching.onActionViewCollapsed()
true
}
