android弹出式菜单(效果爆炸)

有没有觉得常见的弹出菜单都很丑，常见的上下文菜单也很难看，当弹出一个菜单提供功能的时候，整个一点效果都没有。显得很突兀。下面介绍一个菜单。重写了popupwindow 。效果图如下。 github地址github传送门

话不多说上代码：

public class PathPopupWindow extends PopupWindow {    private final int CONST_R = 100;//圆半径    private final int CONST_ICON_SIZE = 35;    private Context context;    private FrameLayout frameLayout;    private ImageView imageView;
