"错误"好奇怪其他时候我已经做过了,从来没有尝试过这个问题......
我的searchview不会调用onOptionsItemSelected如果我把" appname:actionViewClass =" android.support.v7.widget.SearchView"在菜单上。
清单
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<activity
android:name=".DashBoardActivity"
android:label="">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
dash_board.xml(菜单)(如果我撤回actionViewClass他调用(onOptionsItemSelected),但如果我把他不打电话)
<menu xmlns:android="http://schemas.android.com/apk/res/android"

DashBoardActivity
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.dash_board, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
switch (id)
{
case R.id.action_search:
mSearchView
.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
ToastMensagem("Digite um endereço.");
} else {
BuscarEndereco(mSearchView.getQuery().toString());
}
}
});
break;
}
return super.onOptionsItemSelected(item);
}
错误是,不是调用onOptionsItemSelected,我需要操纵searchview
答案 0 :(得分:15)
我现在知道它已经太晚了,但如果其他人发现它有用,我仍在写答案。 昨天我遇到了同样的问题,我通过更改菜单xml文件中的以下行来解决它
appname:showAsAction="always"
到
appname:showAsAction="always|collapseActionView"
您必须在collapseActionView
中添加appname:showAsAction
以及always
以在searchView上启用onOptionsItemSelected
答案 1 :(得分:0)
每当我将collapseActionView添加到菜单项时,操作栏标题将隐藏在搜索视图上。这就是为什么我在寻找一种方法将其保留为
android:showAsAction="always"
&#13;
使用onOptionsItemSelected功能。如果有人发现任何事情,请告诉我! :)

请注意,要提交搜索结果,您不应使用SearchView.setOnQueryTextFocusChangeListener
应该使用SearchView.setOnQueryTextListener
代替。
以下是搜索提交监听器的示例:
case R.id.action_search:
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
Toast.makeText(getActivity(),
getString(R.string.abc_searchview_description_submit),
Toast.LENGTH_SHORT)
.show();
updateUI(query);
return true;
}
@Override
public boolean onQueryTextChange(String query) {
// Clear search
if (query.equals("")) {
updateUI(null);
}
return true;
}
});
