SearchView不会扩展全宽

Question

我有下一个结果:

menu.xml文件

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_search"
        android:actionLayout="@layout/my_search_view"
        android:icon="@android:drawable/ic_menu_search"
        android:title="Search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="always|collapseActionView"/>

</menu>

my_search_view.xml

<?xml version="1.0" encoding="utf-8"?>
<SearchView xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:maxWidth="10000dp"/>

活动

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    getMenuInflater().inflate(R.menu.menu, menu);
    MenuItem searchItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
    searchView.setQueryHint("?????");
    searchView.setOnQueryTextListener(this);


    // Get the SearchView and set the searchable configuration
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));


    ActionBar.LayoutParams params = new ActionBar.LayoutParams(ActionBar.LayoutParams.MATCH_PARENT, ActionBar.LayoutParams.MATCH_PARENT);
    searchView.setLayoutParams(params);
    searchView.setIconified(false);

    MenuItemCompat.expandActionView(searchItem);
    return super.onCreateOptionsMenu(menu);
}

我希望X(关闭动作)位于屏幕右侧.

MenuItemCompat的SearchView有一个名为maxWidth的属性.以下是诀窍:

searchView.setMaxWidth( Integer.MAX_VALUE );
