单击后删除通知

Question

我刚刚开始处理通知,现在我尝试删除通知,并在通知中心点击通知后启动应用程序.

我尝试使用以下代码:

import android.app.NotificationManager;

public class ExpandNotification {
     private int NOTIFICATION = 546;
     private NotificationManager mNM;

     public void onCreate() {
        mNM.cancel(NOTIFICATION);
        setContentView(R.layout.activity_on);
        //Toast.makeText(this, "stopped service", Toast.LENGTH_SHORT).show();
    }

我觉得这个代码在点击时执行其他类？

PendingIntent contentIntent = PendingIntent.getActivity(this, REQUEST_CODE, new Intent(this, ExpandNotification.class), 0);

但是,通知不会消失,应用程序也不会启动.但我能够向左或向右滑动它以移除它但这不是我想要的..

Answer 1

使用Notification.Builder或NotificationCompat.Builder调用setAutoCancel(true)Builder实例获得相同的效果.

Answer 2

使用标志 Notification.FLAG_AUTO_CANCEL

Notification notification = new Notification(icon, tickerText, when);
notification.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);

// Cancel the notification after its selected
notification.flags |= Notification.FLAG_AUTO_CANCEL;

并启动应用程序:

NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

// Create a new intent which will be fired if you click on the notification
Intent intent = new Intent(context, App.class);

// Attach the intent to a pending intent
PendingIntent pendingIntent = PendingIntent.getActivity(context, intent_id, intent, PendingIntent.FLAG_UPDATE_CURRENT);

这个答案太晚了,但特别是我写下面的解决方案,因为通知构造函数变得弃用所以使用构建器使用通知,如下所示:

 **.setAutoCancel(true)** is used to remove notification on click

并且整个通知如下:

  private void makeNotification(String title,String msg){

    Intent resultIntent = new Intent(this, MasterActivity.class);

    PendingIntent resultPendingIntent =
            PendingIntent.getActivity(
                    this,
                    0,
                    resultIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT
            );

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setContentIntent(resultPendingIntent)
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentTitle(title)
                    .setAutoCancel(true)
                    .setContentText(msg);

    int mNotificationId = 001;
    NotificationManager mNotifyMgr =
            (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    mNotifyMgr.notify(mNotificationId, mBuilder.build());

}

使用标题和消息调用此方法可以获得完美的通知.

您可以直接.setAutoCancel(true)将此行添加到代码中，以删除点击通知。

必须将其添加到您的构建器变量中。

例子：

mBuilder = new NotificationCompat.Builder(mContext);
mBuilder.setSmallIcon(R.mipmap.ic_launcher);
mBuilder.setContentTitle("Notification")
        .setContentText("Hello")
        .setSound(Settings.System.DEFAULT_NOTIFICATION_URI)
        .setAutoCancel(true)
        .setContentIntent(pendingIntent);
