android_菜单（Menu）的使用

这里介绍android.view.Menu的使用。

 

 

 

 

● 追加菜单的时候，覆盖(override)Activity.onCreateOptionsMenu()方法，并调用Menu.add()方法
● 追加菜单点击操作处理的时候，覆盖(override)Activity.onMenuItemSelected()方法

 

例程源码(Java)

view source

?

01	public class MenuTestActivity extends Activity {

02	private static final int MENU_ID_TEST1 = (Menu.FIRST + 1);

03	private static final int MENU_ID_TEST2 = (Menu.FIRST + 2);

04

05	/** Called when the activity is first created. */

06

@Override

07	public void onCreate(Bundle savedInstanceState) {

08	super.onCreate(savedInstanceState);

09	setContentView(R.layout.main);

10

}

11

12

@Override

13	public boolean onCreateOptionsMenu(Menu menu) {

14	menu.add(Menu.NONE, MENU_ID_TEST1, Menu.NONE, "Menu1");

15	menu.add(Menu.NONE, MENU_ID_TEST2, Menu.NONE, "Menu2");

16

17	return super.onCreateOptionsMenu(menu);

18

}

19

20

@Override

21	public boolean onMenuItemSelected(int featureId, MenuItem item) {

22	boolean ret = true;

23

24	switch (item.getItemId()) {

25

default:

26	ret = super.onMenuItemSelected(featureId, item);

27

break;

28	case MENU_ID_TEST1:

29	Log.v("Test", "Test1 was selected");

30	ret = true;

31

break;

32	case MENU_ID_TEST2:

33	Log.v("Test", "Test2 was selected");

34	ret = true;

35

break;

36

}

37

38	return ret;

39

}

40

}
