But my problem is that I want interaction to both Dialog and the views behind it at the same time. ie I should be able to select one item from the list vie开发者_如何学运维w in the Dialog and also I should be able to click that button again.Is that possible.Pls help

I could do that using LayoutParams.FLAG_NOT_TOUCH_MODAL;
