Textview with background color

I am new to android. I got stuck while doing an application.I have taken 5 textviews with time slots,I would like to show that when I click one text view it should change its background color and when I click another textview the first text view's background color has to disappear and present text view's color has to be highlight. Here I am posting my code:

Image Here

public void onClick(View v) {
    switch (v.getId()){
        case R.id.time_slot_one:
            setTimeSlotOne.setBackgroundColor(Color.parseColor("#bdbdbd"));
        break;

        case R.id.time_slot_two:
            setTimeSlotTwo.setBackgroundColor(Color.parseColor("#bdbdbd"));
            break;
        case R.id.time_slot_three:
            setTimeSlotThree.setBackgroundColor(Color.parseColor("#bdbdbd"));
            break;
        case R.id.time_slot_four:
            setTimeSlotFour.setBackgroundColor(Color.parseColor("#bdbdbd"));
            break;
        case R.id.time_slot_five:
            setTimeSlotFive.setBackgroundColor(Color.parseColor("#bdbdbd"));
            break;
    }
