dear all,
I try to implement a custom button(OnPressButton), and the code is in
below.
In LogCat, I can see the two parameters (btn_up/btn_down) value are
below:
btn_...@drawable/btn_up
btn_do...@drawable/btn_up
But how can I convert this to point to R.drowable.btn_up and
R.drowable.btn_down ?
Thank you.
Ryan
