        Window window =infoDialog.getWindow();
        window.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND );
        WindowManager.LayoutParams wlp = window.getAttributes();
        wlp.gravity = Gravity.BOTTOM;
        wlp.dimAmount=(float) 0.0;
        //wlp.flags = WindowManager.LayoutParams.FLAG_DIM_BEHIND ;

        window.setAttributes(wlp);
        infoDialog.show();
