我想在Fragment Activity中使用选项菜单。我使用以下代码添加option menu：
1.menu_chat.xml
<?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_viewContacts"
android:orderInCategory="100"
android:title="@string/action_view_contacts"
app:showAsAction="never"/>
<item android:id="@+id/action_media"
android:orderInCategory="100"
android:title="@string/action_media"
app:showAsAction ="never"/>
<item android:id="@+id/action_search_message"
android:orderInCategory="100"
android:title="@string/action_search"
app:showAsAction ="never"/>
<item android:id="@+id/action_block"
android:orderInCategory="100"
android:title="@string/action_block"
app:showAsAction ="never"/>
<item android:id="@+id/action_email_chat"
android:orderInCategory="100"
android:title="@string/action_email_chat"
app:showAsAction ="never"/>
<item android:id="@+id/action_clear_chat"
android:orderInCategory="100"
android:title="@string/action_clear_chat"
app:showAsAction ="never"/>
<item android:id="@+id/action_attach"
android:orderInCategory="100"
android:title="@string/action_clear_chat"
android:icon="@drawable/attach"
app:showAsAction ="always"/>
</menu>
2. FragmentActivity的代码
@Override
public boolean onCreateOptionsMenu(Menu menu) {
Log.e("Option Menu","called");
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_chat_activity, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_viewContacts:
return true;
case R.id.action_media:
return true;
case R.id.action_search:
return true;
case R.id.action_block:
return true;
case R.id.action_email_chat:
return true;
case R.id.action_clear_chat:
return true;
case R.id.action_attach:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
当我运行我的代码时，options menu永远不会显示。
我已在Log内部检查onCreateOptionsMenu未被调用。在我的一个屏幕中，我使用了AppCompatActivity。对于该选项菜单正在运行。我必须使用FragmentActivity这里。请帮我解决问题。

答案 0 :(得分：0)
“请仔细检查您是否已将应用主题设置为Holo.Light。我无法解释导致问题的原因，但我能够重现它。在尝试FragmentActivity和AppCompatActivity之间的更改后，我不小心运行FragmentActivity并将主题设置为Theme.AppCompat.Light。这创建了您看到的行为，而未调用onCreateOptionsMenu（）。“
作为一个附带问题，您应该修复onCreateOptionsMenu（）以调用super，如documentation中所述：“派生类应始终调用基本实现”。
