android auto scroll when clicked on edittext

When user click on edittext I want the screen to scroll to show the edittext in the middle of the screen. So I tried to listen to touch (setOnTouchListener, also tried with onClick and onFocuse) and then smoothScrollTo screen to put the edittext in the middle of the screen.

but for some reason when I add the setOnTouchListener to the edittext it doesn't get focus at all.

what do I need to fix? or how can I achieve this?

this is the setOnTouchListener code that cause the edittext not to get focused when clicked:

    et_email.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            ScrollView scrollView = (ScrollView)getView().findViewById(R.id.ScrollViewSendDetails);
            scrollView.smoothScrollTo(0, et_email.getBottom());
            return true;
        }
    });

Use this line of code on your onCreate method . It gives you auto scrolling when you clicked on EditText : 

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);

First I would like to say you have to use "OnFocusListener" and then you have to use Handler like this;

Now, When I click my edittext; keyboard opened and scrollview scrolled to top at the same time :)

et_space.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                final Handler handler;
                handler = new Handler();

                final Runnable r = new Runnable() {
                    public void run() {
                        scrollView.smoothScrollTo(0, 500);
                        handler.postDelayed(this, 200);
                    }
                };
                handler.postDelayed(r, 200);
            }
        });

Unfortunately output program still want double click to scroll 

 final ScrollView scrollView = (ScrollView) findViewById(R.id.scrollview);
            et_space.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    scrollView.smoothScrollTo(0, 500);
                    scrollView.post(new Runnable() {
                        @Override
                        public void run() {
                            et_space.requestFocus();

                        }
                    });
                    return false;
                }
            });

Returning true from the onTouch() method indicates that the touch event is being consumed there. To allow the event to propagate through to the View's own touch listener, you need to return false;.

To get the EditText to gain focus after the ScrollView has finished its scroll, you can post a Runnable to the ScrollView's handler to request focus on the EditText. For example:

et_email.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            ...
            scrollView.smoothScrollTo(0, et_email.getTop());
            scrollView.post(new Runnable() {
                    @Override
                    public void run() {
                        et_email.requestFocus();
                    }
                }
            );
            return false;
        }
    }
);
