android - 更改 Actionbar 中搜索的图标

Question

我使用以下代码向操作栏添加了搜索:

activity_main_actions.xml

<!-- Search  -->
<item android:id="@+id/action_search"
      android:icon="@drawable/ic_action_search"
      android:title="@string/action_search"
      android:showAsAction="ifRoom"
      android:actionViewClass="android.widget.SearchView"/>


<!-- Add -->
<item android:id="@+id/action_add_tip"
      android:icon="@drawable/header_add"
      android:title="@string/action_add_tip"
      android:showAsAction="ifRoom" />

<!-- Count -->
<item android:id="@+id/action_count_tip"
      android:icon="@drawable/header_count"
      android:title="@string/action_count_tip"
      android:showAsAction="ifRoom" />

在 MainActivity.java 中

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

    // Associate searchable configuration with the SearchView
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));


    return super.onCreateOptionsMenu(menu);
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Take appropriate action for each action item click
    switch (item.getItemId()) {
    case R.id.action_search:
        // search action
        return true;

    default:
        return super.onOptionsItemSelected(item);
    }
}

searchable.xml

 @Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Take appropriate action for each action item click
    switch (item.getItemId()) {
    case R.id.action_search:
        // search action
        return true;

    default:
        return super.onOptionsItemSelected(item);
    }
}

list .xml

  <activity
        android:name="com.emy.healthytips.MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboardHidden|orientation|screenSize"
        android:launchMode="singleTop">
        <meta-data
            android:name="android.app.default_searchable"
            android:value=".MainActivity" />

        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />

        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
    </activity>

搜索对我来说运行良好，但操作栏中的搜索图标仍然像下面的屏幕截图一样是“灰色图标”，尽管我在中添加了自己的图标 <item android:id="@+id/action_search"
android:icon="@drawable/ic_action_search"

如何添加自己的图标？
