You have several options:

  1. Activity.onBackPressed()
  2. Activity.onKeyDown() or Activity.onKeyUp()
  3. View.setOnKeyListener() on each of your EditTexts
  4. View.onKeyPreIme()

I'd probably go with #1 or #3

you can do it by oveeriding the onBackPressed method

@Override
public void onBackPressed() {
    //check here which edittext has current focus,change the focus to previous edittext
    //you can use edittext array also.And also check if it is the first edittext then do nothing
    return;
}

Try something like this...

@Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK)) {
            if(editText_Pin2.getText().toString().length()==1){//Here you will check the last editField which has lenght == 1 
                        editText_Pin1.requestFocus();
                        return false;//This will make sure your activity doesn't gets finished
            }
       }
        return super.onKeyDown(keyCode, event);
    }

Hope this helps..
