There is an additional method to switch the image of the numbers. The R.id.imagefile is the representation of the actual drawable image resources. Since we have 10 images altogether, and R.id returns int, so we can use the switch case 10 times as follows:

//this method is to change the number that appears on the screen // after the navigation button is clicked // as R.id retuns int so we use switch private void changeNumber(int screen){ switch (screen){ case 0: imagenumber.setImageResource(R.drawable.no0); break; case 1: imagenumber.setImageResource(R.drawable.no1); break; case 2: imagenumber.setImageResource(R.drawable.no2); break; case 3: imagenumber.setImageResource(R.drawable.no3); break; case 4: imagenumber.setImageResource(R.drawable.no4); break; case 5: imagenumber.setImageResource(R.drawable.no5); break; case 6: imagenumber.setImageResource(R.drawable.no6); break; case 7: imagenumber.setImageResource(R.drawable.no7); break; case 8: imagenumber.setImageResource(R.drawable.no8); break; case 9: imagenumber.setImageResource(R.drawable.no9); break; } }//end changeNumber
