How to Set Opacity (Alpha) for View in Android

i want to ask two questions:

1) i want to make the buttons in my main.xml i.e simply the first screen look semi-transparent.
It should be such that the background image can be partly-seen through it. But the button should maintain its normal size and looks.

2)(This is regarding another button in another view) i changed the background of buttons using

android:background="#2563EA"

but now when it is clicked it does not change its color. how can i reset it. also can anyone tell me how to give it a new onClick color.

Answer 1

To change the appearance of a button depending on state, use a StateList.
