Keyboard not showing up on EditText when return true

Question

So I have added these lines inside onCreate such that when I click or touch the EditText it performs the action specified in doSomething . The problem is that with the code as presented below, after executing doSomething the keyboard doesn't show up. If I remove the return true inside the if block, then it works, but I don't understand why it fails to work if this line is included. So why does this happen?

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        editText = (EditText)findViewById(R.id.editText);
        editText.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(event.getAction() == MotionEvent.ACTION_UP) {
                    doSomething(editText);
                    return true;
                }
                return false;
            }
        });
    }

Answer 1

it happens because keyboard will show when MotionEvent.ACTION_UP will be handled by EditText itself (not your custom OnTouchListener ), so your onTouch should return false then

in general flag returned by onTouch informs framework that you've handled event - when you returning true then this event won't be propagated further (as already handled, "consumed"). if false returned then event still will be propagated to this View (and handled under the hood, check out particular sources how) or even to its parent if default implementation of View doesn't handle this action and also return false

this isn't the case of EditText - it is handling all events and like in first paragraph - ACTION_UP will show keyboard. but returning true in your first-in-order custom OnTouchListener prevent that
