Question

我正在使用API 8开发应用程序。现在我正在尝试在菜单中添加3个项目，一个我添加的项目是SearchView，我用app:actionViewClass="android.support.v7.widget.SearchView"来支持API 8，在onOptionsItemSelected(MenuItem item)的我的MainActivity类中，我正在尝试处理searchView上的点击，但它已不再有效。怎么解决这个问题？

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">

    <!--My SearchView--->
    <item
        android:id="@+id/menu_search"
        android:orderInCategory="100"
        android:title="@string/stringSearch"
        app:actionViewClass="android.support.v7.widget.SearchView"
        android:icon="@drawable/ic_magnify"
        app:showAsAction="always"/>

    <!--My Filter--->
    <item
        android:id="@+id/menu_filter"
        android:orderInCategory="100"
        android:icon="@drawable/ic_filter"
        android:title="@string/StringFilter"
        app:showAsAction="always" />

    <!--Some menu--->
    <item
        android:id="@+id/menu_settings"
        android:orderInCategory="100"
        android:icon="@drawable/ic_dots"
        android:title="@string/Settings"
        app:showAsAction="always" />

</menu>

MainActivity.class

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        ...
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);

        //I setup the searchView here
        MenuItem searchItem = menu.findItem(R.id.menu_search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
        ....
        return super.onCreateOptionsMenu(menu);
    }

     @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.menu_search:
                //This is click event on searchView but unfortunately not working
                Toast.makeText(getApplicationContext(),"SearcView",Toast.LENGTH_LONG).show();
                break;
            case R.id.menu_settings:
                 Toast.makeText(getApplicationContext(),"Menu Settings",Toast.LENGTH_LONG).show();
                break;
            case R.id.menu_filter:
                Toast.makeText(getApplicationContext(),"Menu Filter",Toast.LENGTH_LONG).show();
                break;
            default:
                break;
        }
        return super.onOptionsItemSelected(item);
    }

}

所以，正如你在我的代码中看到的那样，当我点击菜单项时，我尝试触发一个吐司，一切正常但不是我的SearchView。当我开始在searchView项目的菜单上添加app:actionViewClass="android.support.v7.widget.SearchView"时会发生这种情况。有人可以帮帮我吗？非常感谢你！

您希望在SearchView类上使用其中一个侦听器。 OnSearchClickListener看起来可能适合您。

编辑。这是一个代码示例：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);

    MenuItem searchItem = menu.findItem(R.id.menu_search);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);

    searchView.setOnSearchClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Handle clicks
            }
    });

    return super.onCreateOptionsMenu(menu);
}

Android操作栏SearchView与item.getItemId（）无法正常工作
