Android Studio: scrollTo in Horizontal function isn't working

Question

I'm making this converter app and have spent some time trying to figure out how to work this scrollTo() function to scroll to the button I desire it to be focused in a Horizontal Scroll View.

I've implemented the following to my onCreate:

        final HorizontalScrollView HscrollView1 = (HorizontalScrollView)findViewById(R.id.hsView1);
        final HorizontalScrollView HscrollView2 = (HorizontalScrollView)findViewById(R.id.hsView2);

        final Button cmBtn = (Button)findViewById(R.id.cm_id);
        final Button KmBtn = (Button)findViewById(R.id.km_id);
        final Button mmBtn = (Button)findViewById(R.id.mm_id);

        HscrollView1.scrollTo((int) mmBtn.getX(), 0);
        HscrollView2.scrollTo((int) cmBtn.getX(), 0);

After running APK, it won't scroll to mm and cm button when the app starts (unlike what I wrote in the code)

It seems so frustrating to me with this scrollview and it would be awesome if someone can help me here at 5am (est)

Thank you!

Answer 1

replace

    HscrollView1.scrollTo((int) mmBtn.getX(), 0);
    HscrollView2.scrollTo((int) cmBtn.getX(), 0);

with

new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    HscrollView1.scrollTo((int) mmBtn.getX(), 0);
                    HscrollView2.scrollTo((int) cmBtn.getX(), 0);
                }
            }, 500);

and run your code.
