【问题描述】：
您好，我正在尝试实现 SearchView，就像我们在 Gmail 中一样。
@Override
public boolean onCreateOptionsMenu(Menu menu) {
if (!mNavigationDrawerFragment.isDrawerOpen()) {
getMenuInflater().inflate(R.menu.main, menu);
searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
restoreActionBar();
return true;
}
return super.onCreateOptionsMenu(menu);
}
searchView 对象为空
清单：

可搜索的.xml

<item
android:id="@+id/action_settings"
android:orderInCategory="100"
android:title="@string/action_settings"
app:showAsAction="never"/></menu>
谁能帮助理解为什么这个对象为空？ 谢谢！！！！
【问题讨论】：

不应该是
app:actionViewClass吗？你在扩展ActionBarActivity吗？ -
是的，黑带大获成功！！！那个固定的：D
