通知中的待定意图不起作用 [英] Pending intent in notification not working

问题描述

下面是我的代码块，当点击通知时它应该打开 NotificationActivity.但它不工作.

Below is my block of code which should open NotificationActivity when the notification is tapped on. But its not working.

private void setNotification(String notificationMessage) {
    Uri alarmSound = getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    mNotificationManager  = getApplication().getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(getApplicationContext(), NotificationActivity2.class);

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext())
    .setSmallIcon(R.drawable.logo)
    .setContentTitle("My Notification")
    .setStyle(new NotificationCompat.BigTextStyle()
    .bigText(notificationMessage))
    .setContentText(notificationMessage).setAutoCancel(true);
    mBuilder.setSound(alarmSound);
    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

}

推荐答案

试试这个:

private void setNotification(String notificationMessage) {

//**add this line**
int requestID = (int) System.currentTimeMillis();

Uri alarmSound = getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
mNotificationManager  = getApplication().getSystemService(Context.NOTIFICATION_SERVICE);

Intent notificationIntent = new Intent(getApplicationContext(), NotificationActivity2.class);

//**add this line**
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); 

//**edit this line to put requestID as requestCode**
PendingIntent contentIntent = PendingIntent.getActivity(this, requestID,notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext())
.setSmallIcon(R.drawable.logo)
.setContentTitle("My Notification")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(notificationMessage))
.setContentText(notificationMessage).setAutoCancel(true);
mBuilder.setSound(alarmSound);
mBuilder.setContentIntent(contentIntent);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

}
