Velval solution is the only solution that works and compatiple with different Android vesrions. I tried it on api 17 and 23. but it has an issue that it prevent original on click listener on Android 6. so here is what worked with me. to use touch instead of click:

public class MyTimePicker extends TimePicker {

    private OnTimeChangedListener onTimeChangedListener;

    public MyTimePicker(Context context) {
        super(context);
        //  init();
    }

    public MyTimePicker(Context context, AttributeSet attrs) {
        super(context, attrs);
        //init();
    }

    public MyTimePicker(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        // init();
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public MyTimePicker(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        // Stop ScrollView from getting involved once you interact with the View
        if (ev.getActionMasked() == MotionEvent.ACTION_DOWN) {
            ViewParent p = getParent();
            if (p != null)
                p.requestDisallowInterceptTouchEvent(true);
        }
        return false;
    }

    @Override
    public void setOnTimeChangedListener(OnTimeChangedListener onTimeChangedListener) {
        super.setOnTimeChangedListener(onTimeChangedListener);
        this.onTimeChangedListener = onTimeChangedListener;
    }

    @Override
    protected void onFinishInflate() {
        super.onFinishInflate();
        init();
    }

    private void init() {

        try {
            ViewGroup amPmView;
            ViewGroup v1 = (ViewGroup) getChildAt(0);
            ViewGroup v2 = (ViewGroup) v1.getChildAt(0);
            if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
                ViewGroup v3 = (ViewGroup) v2.getChildAt(0);
                amPmView = (ViewGroup) v3.getChildAt(3);
            } else {
                amPmView = (ViewGroup) v2.getChildAt(3);
            }
            View.OnTouchListener listener = new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
                        onTimeChangedListener.onTimeChanged(MyTimePicker.this, getCurrentHour(), getCurrentMinute());
                    } else {
                        int hour = getCurrentHour();
                        if (hour >= 12) {
                            hour -= 12;
                        } else {
                            hour += 12;
                        }
                        onTimeChangedListener.onTimeChanged(MyTimePicker.this, hour, getCurrentMinute());
                    }

                    return false;
                }

            };
            View am = amPmView.getChildAt(0);
            View pm = amPmView.getChildAt(1);

            am.setOnTouchListener(listener);
            pm.setOnTouchListener(listener);
        } catch (Exception e) {
            // DO nothing... just ignore the workaround if this fails.
        }
