Popup Popupwindow background Dimming implementation

popup Popuowindow After the code is set is Popupwindow default to get focus so popupwindow display when other control click is unresponsive

The method used is

Pwmypopwindow.setfocusable (TRUE);

The Code also sets the

   pwmypopwindow.setbackgrounddrawable ( This.getresources (). getdrawable (   
   R.mipmap.ic_launcher)) ;//Set background picture, cannot be set in layout, to be set by code   
  pwmypopwindow.setoutsidetouchable (true) ;  Touch Popupwindow outside, Popupwindow disappears. This requires your popupwindow to have a background image to succeed   
  
 
  
 is used 
  

Windowmanager.layoutparams LP = GetWindow (). GetAttributes ();
Lp.alpha = Bgalpha; 0.0-1.0
GetWindow (). SetAttributes (LP);

Here is the code
