/**

* @param bgalpha 
*/ 
public void backgroundalpha(float bgalpha) 
{ 
  windowmanager.layoutparams lp = getwindow().getattributes(); 
  　　　　lp.alpha = bgalpha; //0.0-1.0 
    getwindow().setattributes(lp); 
} 

调用代码

recompopup = new recompopup(mcontext); 
      recompopup.setshowlistener(new recompopup.showlistener() { 
        @override 
        public void show() { 
          backgroundalpha(0.6f); 
        } 
      }); 
      recompopup.setdismisslistener(new recompopup.dismisslistener() { 
        @override 
        public void dismiss() { 
          backgroundalpha(1f); 
        } 
      }); 
      recompopup.showatlocation(include_bottom, gravity.no_gravity, 0, devicesinfoutils.getscreenheight(mcontext) - recompopup.getheight()); 

popwindow代码

private showlistener showlistener; 
private dismisslistener dismisslistener; 
 
  @override 
  public void showatlocation(view parent, int gravity, int x, int y) { 
    super.showatlocation(parent, gravity, x, y); 
    if (showlistener != null){ 
      showlistener.show(); 
    } 
  } 
 
  @override 
  public void dismiss() { 
    super.dismiss(); 
    if (dismisslistener != null){ 
      dismisslistener.dismiss(); 
    } 
  } 
 
  public void setshowlistener(showlistener showlistener) { 
    this.showlistener = showlistener; 
  } 
 
  public void setdismisslistener(dismisslistener dismisslistener) { 
    this.dismisslistener = dismisslistener; 
  } 
 
  public interface showlistener{ 
    void show();
