Notification 的用法

public class Activity01 extends Activity
{
Buttonm_Button1, m_Button2, m_Button3, m_Button4;

//声明通知（消息）管理器
NotificationManagerm_NotificationManager;
Intentm_Intent;
PendingIntentm_PendingIntent;
//声明Notification对象
Notificationm_Notification;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//初始化NotificationManager对象
m_NotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

//获取4个按钮对象
m_Button1 = (Button) findViewById(R.id.Button01);
m_Button2 = (Button) findViewById(R.id.Button02);
m_Button3 = (Button) findViewById(R.id.Button03);
m_Button4 = (Button) findViewById(R.id.Button04);

//点击通知时转移内容
m_Intent = new Intent(Activity01.this, Activity02.class);

m_Notification = new Notification();

m_Button1.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v)
{
//设置通知在状态栏显示的图标
m_Notification.icon = R.drawable.img1;
//当我们点击通知时显示的内容
m_Notification.tickerText = "Button1通知内容...........";
//m_Notification.
//通知时发出默认的声音
m_Notification.defaults = Notification.DEFAULT_SOUND;


//主要是设置点击通知时显示内容的类
m_PendingIntent = PendingIntent.getActivity(Activity01.this, 0, getIntent(), 0);
//构造Notification对象

//设置通知显示的参数
m_Notification.setLatestEventInfo(Activity01.this, "Button1", "Button1通知", m_PendingIntent);
//可以理解为执行这个通知
m_NotificationManager.notify(0, m_Notification);
}
});

m_Button2.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {

//取消通知
m_NotificationManager.cancel(0);
}
});

}}
