/** * 点击评分，如果评分后，显示的弹出框 */ private void showMakeGradeMarkedWindow() { View view = LayoutInflater.from(DetailActivity.this).inflate( R.layout.grade_screen_marked, null); final PopupWindow mPopupWindow = new PopupWindow(view, 469, 280); mPopupWindow.setFocusable(true); ColorDrawable dw = new ColorDrawable(0xb0000000); mPopupWindow.setBackgroundDrawable(dw); mPopupWindow.showAtLocation(install, Gravity.CENTER, 0, 0); final RatingBar mraRatingBar = (RatingBar) view .findViewById(R.id.grade_screen); mraRatingBar.setRating(4.5f); // mraRatingBar.setEnabled(false); // 设置背景颜色变暗 WindowManager.LayoutParams lp = getWindow().getAttributes(); lp.alpha = 0.7f; getWindow().setAttributes(lp); mPopupWindow.setOnDismissListener(new OnDismissListener() { @Override public void onDismiss() { WindowManager.LayoutParams lp = getWindow().getAttributes(); lp.alpha = 1f; getWindow().setAttributes(lp); } }); }

当popupWindow消失后，监听其消失的方法，，让背景恢复原样。
