Button outside the circle view

[marcoin]

hello Hitomi,
i have 5 Buttons in my Activity, when i click on the any button, its menu should be opened as a circle

i tried to put the implementation of the circle menu inside the onclick of btn_car button but it did't work
` @OverRide
public void onClick(View v) {
switch (v.getId()){
case R.id.btn_car:
//Here the implementation of circle Menu of Car, when btn_car is clicked

       break;`

Can you please help?
