- 创建Notification
NotificationCompat.Builder mBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("My notification")
.setContentText("hello world!");
- 对Notification添加Action
Intent resultIntent = newIntent(this,ResultActivity.class);
PendingIntent resultPendingIntent = PendingIntent.getActivity(
this,
0,
resultIntent,PendingIntent.FLAG_UPDATE_CURRENT);
//设置点击行为，和Notification相关联起来
mBuilder.setContentIntent(resultPendingIntent);
- 发布一个Notification
//设置ID为001？
int mNotificationId = 001;
NotificationManager mNotifyMgr = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
//要在setContentIntent之后完成
mNotifyMgr.notify(mNotificationId,mBuilder.build());
- 设置一个带有返回栈的Intent,不会返回到MainActivity中
<activity
android:name=".ResultActivity"
android:parentActivityName=".MainActivity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity" />
</activity>
再设置Intent
Intent resultIntent = new Intent(this,ResultActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
//添加到返回栈中
stackBuilder.addParentStack(ResultActivity.class);
//添加Intent到栈顶
stackBuilder.addNextIntent(resultIntent);
//获得带有整个返回栈的PendingIntent
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
//Notification和Intent进行绑定
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(id,mBuilder.build());
- 创建一个特定的PendingIntent，按back会返回到之前的MainActivity
首先要在activity中添加两个属性
android:taskAffinity
android:excludeFromRecents代表是否将它从最近使用中移除
android:taskAffinity=""
android:excludeFromRecents="true"
Intent notifyIntent = new Intent(Intent.makeMainActivity(new ComponentName(this, ResultActivity.class)));
//将用来放置activity的task清空,然后再在task中启动
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent notifyPendingIntent = PendingIntent.getActivity(
this,
0,
notifyIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(notifyPendingIntent);
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(id,mBuilder.build());
- 更新Notification内容只要知道id，再通过notify()即可
//Modify a Notification,by calling NotificationManager.notify(ID,notification);
int numMessages = 0;
mBuilder.setContentText("3").setNumber(++numMessages);
mNotificationManager.notify(id,mBuilder.build());
- 删除Notification有四种方法
(1) 用户通过点击"Clear All"
(2) 在设置Notification的时候setAutoCancel(true);
(3) 通过调用cancel();
(4) 通过调用cancelAll();移除以前该应用的所有通知 - 设置Big View
创建两个Action
Intent dismissIntent = new Intent(this,PingService.class);
dismissIntent.setAction("com.example.hellokai..ACTION_DISMISS");
PendingIntent piDismiss = PendingIntent.getService(this,0,dismissIntent,0);
Intent snoozeIntent = new Intent(this,PingService.class);
snoozeIntent.setAction("com.example.hellokai.ACTION_SNOOZE");
PendingIntent piSnooze = PendingIntent.getService(this,0,snoozeIntent,0);
NotificationCompat.Builder builder =
(NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("hello")
.setContentText("big view")
.setDefaults(Notification.DEFAULT_ALL)
.setStyle(new NotificationCompat.BigTextStyle().bigText("hello result"))
.addAction(R.mipmap.ic_launcher,"dismiss",piDismiss)
.addAction(R.mipmap.ic_launcher,"snooze",piSnooze);
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(id,builder.build());
9.通知设置进度条
final NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
new Thread(
new Runnable() {
@Override
public void run() {
int incr;
for(incr = 0;incr <= 100;incr+=5) {
mBuilder.setProgress(100,incr,false);
manager.notify(id,mBuilder.build());
try{
Thread.sleep(1*1000);
}catch(InterruptedException e){
e.printStackTrace();
}
}
//结束之后要重新更新为0，false表示没有进图条动画，true表示有
mBuilder.setContentText("download complete").setProgress(0,0,false);
manager.notify(id,mBuilder.build());
}
}).start();
