Open specific tab from Pending Intent

Question

I am trying to set the focus on the specific tab after click on Push Notification I am unable to redirect it, here is my code

 Intent intent_chat=new Intent(this, HomeChatFragment.class);
 pendingIntent=PendingIntent.getActivity(this,0,intent_chat,PendingIntent.FLAG_UPDATE_CURRENT);

Any kind of guidance will be great, thanks!

Answer 1

Intent intent_chat=new Intent(this, HomeChatFragment.class);
intent.putExtra("someFlag", 2); //tab position to open
pendingIntent=PendingIntent.getActivity(this,0,intent_chat,PendingIntent.FLAG_UPDATE_CURRENT);

and in your HomeChatFragment.java do this:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ...
        ...
        int i;
        if(getIntent() != null) {
            i = getIntent().getIntExtra("someFlag", -1);
       }
       if(i != -1) {
           yourViewPager.setCurrentItem(i);
       }
   }
