Change state of a button from code

Question

How to change the states of buttons from the code. I cannot use xml files since I am getting the images from the server.

Using :

Drawable d = new BitmapDrawable(getResources(),bitmap);

I have got the drawable but how do I assign different states and then attach corresponding images for the button?

Take a look at this. http://stackoverflow.com/questions/2604599/android-imagebutton-with-a-selected-state — Nate-Wilkins, Aug 13 '12 at 19:50

In xml, we use <selector> element to do so. In code, we use StateListDrawable :

StateListDrawable content = new StateListDrawable();
Drawable pressedDrawable = new BitmapDrawable(getResources(),bitmap);
//Your other drawables (focused, .....)

content.addState(new int[] { android.R.attr.state_pressed }, pressedDrawable);
//Add the other drawables the same way

Button button = (Button) view.findViewById(R.id.my_button);
button.setBackground(content);

I guess it should be button.setBackground(content); – dejavu Aug 13 '12 at 20:32
You are right. I was using `ImageButton` in my code and I changed it to match yours but I forgot to change this. Edited. – iTurki Aug 13 '12 at 22:20
