如何在触摸时删除通知？

Question

我正在尝试开发一个应用程序，它会在您退出时发出通知。但我希望当您触摸通知并重新打开应用程序时，通知会消失。我该怎么做？

我的代码：

public class MainActivity extends Activity {

    NotificationCompat.Builder mBuilder;

    @SuppressWarnings("deprecation")    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_main_land);
        this.setVolumeControlStream(AudioManager.STREAM_MUSIC);


        mBuilder =
                new NotificationCompat.Builder(MainActivity.this)
                    .setSmallIcon(android.R.drawable.stat_sys_warning)
                    .setContentTitle("Mensaje de Alerta")
                    .setContentText("Ejemplo de notificación.")
                    .setContentInfo("4")
                    .setTicker("Alerta!");

        }


    public void salir(View view) {

        finish();
        Intent notIntent =
                new Intent(MainActivity.this, MainActivity.class);

            PendingIntent contIntent =
                PendingIntent.getActivity(
                    MainActivity.this, 0, notIntent, 0);

            mBuilder.setContentIntent(contIntent);
            NotificationManager mNotificationManager =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

                mNotificationManager.notify("NOTIFICATION", 0, mBuilder.build());

    }

}

此代码仅生成通知并再次打开应用程序。

使用标志

 notification.flags = Notification.FLAG_AUTO_CANCEL;

使用通知生成器

NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setAutoCancel(true);

使用通知管理器

notificationManager.cancel(NOTIFICATION_ID);

API 18 级及以上

@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)
public class MyNotificationListenerService extends NotificationListenerService {...}
...

private void clearNotificationExample(StatusBarNotification sbn) {
    myNotificationListenerService.cancelNotification(sbn.getPackageName(), sbn.getTag(), sbn.getId());
}
