Android开发之使用Notification.Builder

通知的主要功能是提示功能。例如：短信、推送信息等等。

大体使用步骤：

1.获取状态通知栏管理

NotificationManager 是一个系统Service，所以必须通过 getSystemService(NOTIFICATION_SERVICE)方法来获取。

notificationManager = (NotificationManager) this
				.getSystemService(NOTIFICATION_SERVICE);

2.实例化通知栏构造器NotificationCompat.Builder

3.设置NotificationCompat.Builder

4.设置PendingIntent

5.显示

 

方法或参数介绍：

1.PendingIntent

PendingIntent.getBroadcast(context, requestCode, intent, flags)


PendingIntent.getActivities(context, requestCode, intents, flags)


PendingIntent.getService(context, requestCode, intent, flags)


中的flags属性参数：

FLAG_ONE_SHOT   表示返回的PendingIntent仅能执行一次，执行完后自动取消

FLAG_NO_CREATE     表示如果描述的PendingIntent不存在，并不创建相应的PendingIntent，而是返回NULL

FLAG_CANCEL_CURRENT      表示相应的PendingIntent已经存在，则取消前者，然后创建新的PendingIntent

FLAG_UPDATE_CURRENT     表示更新的PendingIntent

2.notification.flags参数介绍

Notification.FLAG_SHOW_LIGHTS              //三色灯提醒，在使用三色灯提醒时候必须加该标志符

Notification.FLAG_ONGOING_EVENT          //发起正在运行事件（活动中）

Notification.FLAG_INSISTENT   //让声音、振动无限循环，直到用户响应 （取消或者打开）

Notification.FLAG_ONLY_ALERT_ONCE  //发起Notification后，铃声和震动均只执行一次

Notification.FLAG_AUTO_CANCEL      //用户单击通知后自动消失

Notification.FLAG_NO_CLEAR          //只有全部清除时，Notification才会清除 ，不清楚该通知(QQ的通知无法清除，就是用的这个)

Notification.FLAG_FOREGROUND_SERVICE    //表示正在运行的服务

 

使用方法：

 

在设置完属性后，设置

Notification notification =builder.build();
notification.flags =Notification.FLAG_ONLY_ALERT_ONCE;

 

3.setVibrate(long[] pattern)

设置震动，需要权限.

4.builder.setOngoing( )

设置为ture，表示它为一个正在进行的通知。简单的说，当为ture时，不可以被侧滑消失。

使用自定义Notification，就要使用RemoteViews。

实现代码：

MainActivity.java

public class MainActivity extends Activity {

	Button button, button2;
	NotificationManager notificationManager;
	public final static String NEWS_LISTEN = "broadcast";

	// 用于自定义Notification，点击事件的验证
	String remoteViewsText = "未点击";

	@Override
	public void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		notificationManager = (NotificationManager) this
				.getSystemService(NOTIFICATION_SERVICE);

		IntentFilter filter = new IntentFilter();
		filter.addAction(NEWS_LISTEN);
		this.registerReceiver(broadcastReceiver, filter);

	public void click(View v) {
