Android PopWindow 设置背景亮度的实例

设置背景 

/**
* 设置添加屏幕的背景透明度
* @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();
  }

  public interface DismissListener{
    void dismiss();
  }
