Question

Sorry for my bad English.

I have two activity. called Act1 and Act2

Act2 will be started when a Button in Act1 is clicked (startActivity). My question is how to disabled back button in Act2 so, I cannot return to Act1.

Is it possible. Thank you.

How to overcome this problem :

Override onKeyDown Method, end Set finished();

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_BACK)) {
        finish();
    }
    return super.onKeyDown(keyCode, event);
}

Answer 1

It’s been asked before, so you’ll find plenty of good answers here:

Override back button to act like home button

Just override the back key and call finish() instead. That way it won’t go back to the first activity, it’ll just close.
