OptionMenu不显示任何内容

[英]OptionMenu does not show anything

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    // mEditor=(TextView)findViewById(R.id.text);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {

    super.onCreateOptionsMenu(menu);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu, menu);

    Log.d("sayem", "onCreateOptionMEnu");

    return true;

}

And this is my menu.xml file path res/menu/menu.xml 这是我的menu.xml文件路径res / menu / menu.xml

<item
    android:id="@+id/settings"
    android:alphabeticShortcut="@string/settings_shortcut"
    android:icon="@drawable/violet"
    android:title="@string/settings_label"
    android:visible="true"/>

It does not show any kind of menu as expected. 它没有显示任何菜单如预期的那样。

If you look at the example here , the menu.xml file (or game_menu.xml file) has an outer tag called <menu> . 如果在此处查看示例,则menu.xml文件(或game_menu.xml文件)具有名为<menu>的外部标记。 I don't see that in yours. 我看不到你的。

Example: 例:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/new_game"
          android:icon="@drawable/ic_new_game"
          android:title="@string/new_game" />
    <item android:id="@+id/help"
          android:icon="@drawable/ic_help"
          android:title="@string/help" />
</menu>

Either you have not posted your full menu.xml, or it isn't formed as it should be. 您可能尚未发布完整的menu.xml,或者未按预期形成。
