I construct my own class  and then call it from my activity  overriding small methods like showAtLocation  I ve found its easier when I have 4 to 5 popups in my activity to do this   public class ToggleValues implements OnClickListener       private View pView      private LayoutInflater inflater      private PopupWindow pop      private Button one  two  three  four  five  six  seven  eight  nine  blank      private ImageButton eraser      private int selected   1      private Animation appear       public ToggleValues int id  Context c  int screenHeight           inflater    LayoutInflater  c getSystemService Context LAYOUT INFLATER SERVICE           pop   new PopupWindow inflater inflate id  null  false   265   int  screenHeight   0 45   true           pop setBackgroundDrawable c getResources   getDrawable R drawable alpha 0            pView   pop getContentView             appear   AnimationUtils loadAnimation c  R anim appear            one    Button  pView findViewById R id one           one setOnClickListener this           two    Button  pView findViewById R id two           two setOnClickListener this           three    Button  pView findViewById R id three           three setOnClickListener this           four    Button  pView findViewById R id four           four setOnClickListener this           five    Button  pView findViewById R id five           five setOnClickListener this           six    Button  pView findViewById R id six           six setOnClickListener this           seven    Button  pView findViewById R id seven           seven setOnClickListener this           eight    Button  pView findViewById R id eight           eight setOnClickListener this           nine    Button  pView findViewById R id nine           nine setOnClickListener this           blank    Button  pView findViewById R id blank Selection           blank setOnClickListener this           eraser    ImageButton  pView findViewById R id eraser           eraser setOnClickListener this              public void showAtLocation View v            pop showAtLocation v  Gravity BOTTOM   Gravity LEFT  40  40           pView startAnimation appear              public void dismiss             pop dismiss               public boolean isShowing             if pop isShowing                 return true           else              return false                       public int getSelected            return selected             public void onClick View arg0            if arg0    one               Sudo setToggleNum 1            else if arg0    two               Sudo setToggleNum 2            else if arg0    three               Sudo setToggleNum 3            else if arg0    four               Sudo setToggleNum 4            else if arg0    five               Sudo setToggleNum 5            else if arg0    six               Sudo setToggleNum 6            else if arg0    seven               Sudo setToggleNum 7            else if arg0    eight               Sudo setToggleNum 8            else if arg0    nine               Sudo setToggleNum 9            else if arg0    blank               Sudo setToggleNum 0            else if arg0    eraser               Sudo setToggleNum -1                     this dismiss
