推荐答案

在您的 menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".HomeActivity">

    <item
        android:id="@+id/action_search"
        android:icon="@android:drawable/ic_menu_search"
        android:title="Search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="always" />
</menu>

并将此简单代码添加到您的java中:

and add this simple code to your java :

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_search:
            // Not implemented here
            return false;
        default:
            break;
    }
    searchView.setOnQueryTextListener(queryTextListener);
    return super.onOptionsItemSelected(item);
}
