Answer 1

You should use Selector .
Edit: Use selector drawable as a background for ListView elements, or specify a android:listSelector for a ListView

Answer 2

you have change background color in onfocusChangeListener. Try with following code,

livView.setOnFocusChangeListener(new OnFocusChangeListener() {

            @Override
            public void onFocusChange(View v, boolean hasFocus) {

                TextView tv=(TextView)v.findViewById(R.id.yourId);
                if(hasFocus){
                    tv.setBackgroundColor(bg_color);
                }
            }
        });
