WindowManager.LayoutParams lparams = getWindow().getAttributes();  
lparams.dimAmount=1.0f; 
dialog.getWindow().setAttributes(lparams);

The dim amount 0 means no dimming, and the dim amount 1.0f means complete dimming. Any value in between is the corresponding percentage of dim.

Just add this code to the button you want.
