Answer 1

In the above program you have written

Add the code below when listview1, listview2 and listview3 are initialized.

listview1.setVisibility(View.GONE); listview2.setVisibility(View.GONE); listview3.setVisibility(View.GONE);

When the Onclick method is called for Button1, Add

 listview1.setVisibility(View.VISIBLE);

When the Onclick method is called for Button2, Add

 listview2.setVisibility(View.VISIBLE);

When the Onclick method is called for Button3, Add

 listview3.setVisibility(View.VISIBLE);
