Question

My App starts and loads the first screen, then the users changes to the next screen by clicking a button with:

    Intent intent = new Intent(DashboardActivity.this, LoginActivity.class);
            startActivity(intent);

and then from there, the user changes to the next screen, again with:

    Intent intent = new Intent(LoginActivity.this, NextActivity.class);
            startActivity(intent);

now there should be 3 screens on the stack and in this last screen, I want to go all the way back to the first screen, how do I do that with one click?
I want to send putExtra("") data from that last screen to the first screen.

Answer 1

Add this

In NextActivity,

Intent myIntent = new Intent(NextActivity.this, DashBoardActivity.class);
 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
  myIntent.putExtra("UserName",UserName);
   startActivity(myIntent);

In DashBoardActivity,

Intent intent = getIntent();
UserName=intent.getStringExtra("UserName");
