Show an Alert on clicking Up button of ActionBar

Question

I want to show an Alert Dialog when the user clicks on the up button of ActionBar. I have implemented onBackPressed() already. What I want to do now is trigger same action as for pressing Back button when user clicks the Up button from ActionBar.

I tried using onNavigateUp(). However, it just returns me to the parent activity without showing the Alert Dialog.

from this answer you can override onOptionsItemSelected to detect action

public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
    case android.R.id.home: {
       //enter your code here

        return true;
    }
}
return super.onOptionsItemSelected(item);
}

try it

It works. Only change required is `return true` instead of `break` at the end of `case` block. – dkhost07 Mar 26 '20 at 15:39
