下面是我的代码块，NotificationActivity当点击通知时它应该打开。但它不起作用。
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());

try this:
尝试这个：
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());
}

You might be using a notification id equal to 0. There is known issue with notification id being 0. If you will use any other id, it should work.
您可能正在使用等于 0 的通知 id。通知 id 为 0 存在已知问题。如果您将使用任何其他 id，它应该可以工作。

I added task builder and the below block code worked for me
我添加了任务构建器，下面的块代码对我有用
Intent intent = new Intent(context, HomeActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(SplashActivity.class);
stackBuilder.addNextIntent(intent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

If the app is already running then you need to handle it in onNewIntent
如果应用程序已经在运行，那么你需要处理它 onNewIntent
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
//Handle intent here...
}

Try checking your AndroidManifest.xml, double check if you are navigating to an activity with an intent-filter main action, launcher category
尝试检查您的AndroidManifest.xml，仔细检查您是否正在导航到带有intent-filter main action, launcher category
For example,
例如，
I couldn't make my pending intentto navigate to HomeActivitybut it works when navigating to SplashScreen
我无法pending intent导航到，HomeActivity但它在导航到SplashScreen
Hope this helps.

Added the requestid, but the intent was still not opening.
添加了requestid，但意图仍然没有打开。
This is the solution that worked for me:
这是对我有用的解决方案：
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
Setting those flags to clear the activities below the intent activity.
设置这些标志以清除意图活动下方的活动。
