How to use onCLick when class has onTouchEvent

Question

I have class :

class MyLinearLayout extends LinearLayout {

    public ProLinearLayout(Context context, String options) {
        super(context);

        something();
    }
    private void something() {
        // .....
    }

    -- begin block A
    @Override
    public boolean onTouchEvent(MotionEvent event) { 
        int action = event.getAction();
        if ( action == MotionEvent.ACTION_DOWN ) {
            getBackground().setColorFilter( Color.GRAY, PorterDuff.Mode.ADD );
            invalidate();
        }
        if ( action == MotionEvent.ACTION_CANCEL || action == MotionEvent.ACTION_UP ) {
            getBackground().clearColorFilter();
            invalidate();
        }
        return true;
    }
    -- end block A
}

An I use it :

MyLinearLayout obj = new MyLinearLayout( this_activity);
...
obj.setOnClickListener( new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        // if comment block A, this this code works

        // if using bock A, this code does not work -- WHY. HOW TO RUN THIS CODE WHEN USING BLOCK A
    }
});

When comment onTouchEvent ( block A), the code in onClick is work. When using onTouchEvent ( block A), the code in onClick does not work.

How to run OnClick code when using onTouchEvent same time

you don't need to. You can simply implement OnTouch as OnClick. Refer to these links https://stackoverflow.com/a/19539206/6845131 and https://stackoverflow.com/a/9123001/6845131 — Vishist Varugeese, Mar 20 '20 at 13:58

I have found a solution So use dispatchTouchEvent instead of onTouchEvent

    -- begin block A
    @Override
    public boolean dispatchTouchEvent(MotionEvent event) {
        // 
        int action = event.getAction();
        if ( action == MotionEvent.ACTION_DOWN ) {
            getBackground().setColorFilter( Color.GRAY, PorterDuff.Mode.ADD );
            invalidate();
        }
        if ( action == MotionEvent.ACTION_CANCEL || action == MotionEvent.ACTION_UP ) {
            getBackground().clearColorFilter();
            invalidate();
        }
        // 
        return super.dispatchTouchEvent(event);
    }
    -- end block A
