程式小試身手

官方教學\

對res右鍵

<?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="@mipmap/ic_launcher"
        android:title="按鈕1"
       />
    <item android:id="@+id/help"
        android:icon="@mipmap/ic_launcher"
        android:title="按鈕2" />
</menu>

onCreate(Bundle savedInstanceState) 方法下

@Override
 public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.game_menu, menu);//R.menu.game_menu根據你所建立的menu變化名稱
    return true;
}

點擊事件

@Override
  public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
        case R.id.new_game:
            Log.i("mytest","1");
            return true;
        case R.id.help:
            Log.i("mytest", "2");
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}
