Question

我刚开始处理通知，现在我尝试删除通知，并在通知中心点击通知后启动应用。

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会执行另一个类吗？

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

然而，通知不会消失，应用程序也不会启动。但是我能够向左或向右滑动它以将其移除，但这不是我想要的......

Answer 1

要在Builder实例上使用Notification.Builder或NotificationCompat.Builder调用setAutoCancel(true)来获得相同的效果。

Answer 2

使用标记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：

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，但特别是我写了以下解决方案，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。

Best＆amp;设置NotificationCompat.Builder builder = new NotificationCompat.Builder(this); builder.setSmallIcon(android.R.drawable.btn_star); builder.setContentTitle("This is title of notification"); builder.setContentText("This is a notification Text"); builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));的简单方法是在点击通知后取消您的通知。我希望这段代码可以帮助你。

通知构建器

Intent intent = new Intent(Broadcastdemo.this, ThreadDemo.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 113,intent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);

用于打开点击通知的活动

NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.notify(114, builder.build());

在通知中显示投标

public void ShowIntentNotification(View v)
    {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        builder.setSmallIcon(android.R.drawable.btn_star);
        builder.setContentTitle("This is title of notification");
        builder.setContentText("This is a notification Text");
        builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher));

        Intent intent = new Intent(Broadcastdemo.this, ThreadDemo.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 113,intent, PendingIntent.FLAG_UPDATE_CURRENT);

        builder.setContentIntent(pendingIntent);
        builder.setAutoCancel(true);

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(114, builder.build());

    }

Answer 5

您可以直接在代码中添加.setAutoCancel(true)这一行，以删除点击通知。

必须将其添加到您的构建器变量中。

示例：

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);

Answer 6

对我来说就是那个

.setPriority(Notification.PRIORITY_HIGH);

导致通知在点击后无法清除...请确保使用：

.setPriority(Notification.PRIORITY_DEFAULT);

而且.setAutoCancel(true)应该有用。

单击后删除通知
