+# 简介
+
+> 一个简单的自定义菜单。支持修改布局的颜色，菜单内容，菜单项高度等。
+
+控件预览如下:
+
+![preview](./images/preview.png)
+
+简单使用:
+
+在app/libs目录下引入library-menu.aar.修改app的build.gradle文件。如下图中红框所示:
+
+![gradle](./images/gradle.png)
+
+在Activity中使用:
+
+![user](./images/use.png)
+
+registerContextMenu方法有两个重载，如果不指定加载的资源布局，会默认使用aar中的布局，展示默认的效果。
+
+```java
+public void registerContextMenu(View anchor, List<String> list, MenuManager.MenuListener listener)
+```
+
+如果自定义布局，则使用以下方法加载：
+
+```java
+public void registerContextMenu(View anchor, List<String> list, int layoutId, int menuId, MenuManager.MenuListener listener)
+```
+
+对应的xml示例如下:
+
+![layout](./images/layout.png)
+
+在ondestory方法中，解注册。
+
+```java
+mMenuManager.unregisterContextMenu();
+```
+
+自定义属性:
+
+header_text:标题文字内容
+
+header_text_color:标题文字颜色
+
+header_bg:标题区域背景色
+
+header_height:标题区域高度
+
+divider_bg:标题区域和菜单区域分割线背景色
+
+item_bg:菜单项背景色
+
+item_paddingStart:菜单项padding
+
+item_textColor:菜单文字颜色
+
+item_height:菜单项高度
