		menu.add(menu.NONE,2,menu.NONE,"菜单2");
		menu.add(menu.NONE,3,menu.NONE,"菜单3");
		menu.add(menu.NONE,4,menu.NONE,"菜单4");
		menu.add(menu.NONE,5,menu.NONE,"菜单5");
		return true;
	}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
	switch (item.getItemId()) {
	case 1:
		Toast.makeText(this,"1", Toast.LENGTH_SHORT).show();
		break;

	default:
		Toast.makeText(this,"其他", Toast.LENGTH_SHORT).show();
		break;
	}
	return super.onOptionsItemSelected(item);
}

2.2.SubMenu

@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		menu.add(menu.NONE,1,menu.NONE,"菜单1");
		menu.add(menu.NONE,2,menu.NONE,"菜单2");
		menu.add(menu.NONE,3,menu.NONE,"菜单3");
		menu.add(menu.NONE,4,menu.NONE,"菜单4");
		menu.add(menu.NONE,5,menu.NONE,"菜单5");
		SubMenu subMenu = menu.addSubMenu(menu.NONE,6,menu.NONE,"菜单6"); 
		subMenu.setHeaderTitle("你好");
		subMenu.setIcon(R.drawable.ic_launcher);
		subMenu.addSubMenu(menu.NONE,7,menu.NONE,"菜单7");
		return true;
	}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
	switch (item.getItemId()) {
	case 1:
		Toast.makeText(this,"1", Toast.LENGTH_SHORT).show();
		break;

	default:
		Toast.makeText(this,"其他", Toast.LENGTH_SHORT).show();
		break;
	}
	return super.onOptionsItemSelected(item);
}

2.3ContextMenu

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

TextView textView = (TextView) findViewById(R.id.tv1);
registerForContextMenu(textView);
	}

@Override
public void onCreateContextMenu(ContextMenu menu, View v,
		ContextMenuInfo menuInfo) {
	menu.add(menu.NONE,1,menu.NONE,"菜单1");
	menu.add(menu.NONE,2,menu.NONE,"菜单2");
	menu.add(menu.NONE,3,menu.NONE,"菜单3");
	menu.add(menu.NONE,4,menu.NONE,"菜单4");
	menu.add(menu.NONE,5,menu.NONE,"菜单5");	
	super.onCreateContextMenu(menu, v, menuInfo);
}
	@Override
	public boolean onContextItemSelected(MenuItem item) {
		// TODO Auto-generated method stub
		switch (item.getItemId()) {
		case 1:
			Toast.makeText(this,"1",Toast.LENGTH_SHORT).show();
			break;

		default:
			break;
		}
		return super.onContextItemSelected(item);
	}
}

3.Notification

NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
       //声明Notification
	    Notification notification = new Notification();
	    //设置notification的参数
	    notification.icon=R.drawable.ic_launcher;
	   
	   Intent intent = new Intent(this,MainActivity.class);
	   PendingIntent pendingIntent = PendingIntent.getActivity(this,0, intent,0);
	   notification.setLatestEventInfo(this,"haha" ,"contentText",pendingIntent);
	   notificationManager.notify(10,notification);

4.TabHost

TabHost tabHost = getTabHost();
		LayoutInflater.from(this).inflate(R.layout.activity_main,
				tabHost.getTabContentView(), true);
		Intent intent = new Intent(MainActivity.this, SeocndActivity.class);

		tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("搜索")
				.setContent(intent));
		tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("搜索")
				.setContent(intent));
		tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("搜索")
				.setContent(R.id.l1));
