Bud*_*ddy 6 android android-layout
我正在使用PopupWindow,效果很好,但是问题是在放大显示有黑色边框的布局视图之后。
final PopupWindow popupWindow = new PopupWindow(context);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.pop_up_window_menu_layout, null);
popupWindow.setContentView(view);

我尝试使用删除边框popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)),但问题仍然相同。
谁能告诉我如何删除不需要的黑色边框?
我的弹出窗口周围没有看到任何边框,但我将其设置为与您稍有不同。希望这为您指明了正确的方向。

如果出现黑色边框,则表示已设置默认背景。
这是删除它的方法:
popup.setBackgroundDrawable(null);
