Notification

消息通知：

首先要用到NotificationManager （消息通知）管理器

public class MainActivity extends Activity {
Button m_Button1,m_Button2,m_Button3,m_Button4;
//声明通知管理器
NotificationManager m_NotificationManager;
Intent m_Intent;
PendingIntent pendingIntent;

//声明Notification 对象
Notification m_Notification;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

//初始化NotificationManager对象
m_NotificationManager=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
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);
m_Intent=new Intent(MainActivity.this, Activity2.class);

//设置点击通知时显示的内容
pendingIntent=PendingIntent.getActivity(MainActivity.this, 0, m_Intent, 0);
m_Notification=new Notification();
m_Button1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {

//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。。。。。。";

//通知时发出默认的声音
m_Notification.defaults=Notification.DEFAULT_SOUND;

//设置通知显示的参数
m_Notification.setLatestEventInfo(getApplicationContext(), "button1", "button1通知", pendingIntent);

//可以理解为执行这个通知
m_NotificationManager.notify(0, m_Notification);
}
});
m_Button2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
m_Notification.icon=R.drawable.img2;
m_Notification.tickerText="button2通知内容。。。。。。";

//通知时震动
m_Notification.defaults=Notification.DEFAULT_VIBRATE;
m_Notification.setLatestEventInfo(getApplicationContext(), "button2", "button2通知", pendingIntent);
m_NotificationManager.notify(0, m_Notification);
}
});
m_Button3.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
m_Notification.icon=R.drawable.img3;
m_Notification.tickerText="button3通知内容。。。。。。";

//通知时屏幕发亮
m_Notification.defaults=Notification.DEFAULT_LIGHTS;
m_Notification.setLatestEventInfo(getApplicationContext(), "button3", "button3通知", pendingIntent);
m_NotificationManager.notify(0, m_Notification);
}
});
m_Button4.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
m_Notification.icon=R.drawable.img4;
m_Notification.tickerText="button4通知内容。。。。。。";

//通知时屏幕震动，亮，声音
m_Notification.defaults=Notification.DEFAULT_ALL;
m_Notification.setLatestEventInfo(getApplicationContext(), "button4", "button4通知", pendingIntent);
m_NotificationManager.notify(0, m_Notification);

}
});
}
}
