我想用內部Fragment Activity。我已經使用了下面的代碼添加option menu選項菜單使用OptionsMenu：無法在片段活動
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。 Code of FragmentActivity
@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);
}
}
當我運行我的代碼時，從不顯示options menu。
我已在Log是onCreateOptionsMenu內部檢查不叫。在我的屏幕之一，我已經使用AppCompatActivity。對於該選項菜單工作。我必須使用FragmentActivity這裏。請幫我解決這個問題。
