How to go to parent activity from sub children activity?

Question

Imaginarily, I have a parent activity called 'P'. Mr P has 5 children, called '1','2','3','4','5'.

But the truth in my project is ,

• P have 1 as child.

• 1 have 2 as child.

• 2 have 3 as child.

• and so on.

I travel from P to 1, and from 1 to 2, from 2 to 3, and so on.

The problem is how can i travel from 3 straight to P ? therefore P must be his parent am i wrong?

Here is what i have implemented so far on my back pressed

@Override 
    public void onBackPressed(){
      if (background_tick != null){
          if(background_tick.isPlaying())
              background_tick.stop();
          background_tick.release();
         // finish();
      }
      Intent crush=new Intent(getApplicationContext(),P.class);
      startActivity(crush);
      //super.onBackPressed();
 }

With that code i successfully go to activity P, but when i press 'Back' from P it return to acitivy 3 and i dont want that happen.

Any answer will appreciated guys. greetings from bali.

Answer 1

Set your Intent Flag . it remove activity from top.

Intent crush=new Intent(getApplicationContext(),P.class);
crush.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(crush);

Intent Flag

Answer 2

Uses the Flag

 Intent i = new Intent(3.this,P.class);
 i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 startActivity(i);
