Change xml selector values from java code

Question

I am trying to create a universal image selector for multiple buttons. Is there an option to change the xml's "android:drawable" resource from java code?

for which control you want to set drawable resource. e.g. Button or textview — rajpara

use StateListDrawable for seeting selector by code as:

StateListDrawable states = new StateListDrawable();
states.addState(new int[] {android.R.attr.state_pressed},
    getResources().getDrawable(R.drawable.pressed));
states.addState(new int[] {android.R.attr.state_focused},
    getResources().getDrawable(R.drawable.focused));
states.addState(new int[] { },
    getResources().getDrawable(R.drawable.normal));

imageView.setImageDrawable(states);  //YOUR IMAGE HERE
//AND FOR BUTTON
 button.setBackgroundDrawable(states);//FOR BUTTON
