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();    }
