I added this code and it works for me. This code will hide the button when you open the keyboard and show it again when it is closed.
parentView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
rootView.getWindowVisibleDisplayFrame(r);
int heightDiff = rootView.getRootView().getHeight() - (r.bottom - r.top);
if (heightDiff > 100) { // if more than 100 pixels, its
//Hide Show Key board
view_one.setVisibility(View.GONE);
view_two.setVisibility(View.GONE);
}else{
//ok now we know the keyboard is down...
view_one.setVisibility(View.VISIBLE);
view_two.setVisibility(View.VISIBLE);
}
}
});
