Answer 1

No need to go so deep in your case. Every view has postDelayed() method, that will run a custom code in UI thread after a set amount of time (in milliseconds). For example:

ball5.postDelayed(new Runnable(){
            @Override
            public void run() {
                ball5.setText("");
            }
        }, 3000);

will clear “ball5” text after 3 seconds has passed

Another example
…

if(id==R.id.ball2)
            {
                ball2.setText(Integer.toString(score));
ball2.postDelayed(new Runnable(){
            @Override
            public void run() {
                ball2.setText("");
            }
        }, 3000);
            }
