android ------ 控件Gridview实现多个men

此案例主要讲的是Android控件Gridview（九宫格）完美实现仿支付宝首页，包含添加和删除功能；Fragment底部按钮切换的效果，包含四个模块，登录页面圆形头像等，一个小项目的初始布局。

自定义GridView

<menu.menudemo.ui.view.ZQScrollGridView
    android:id="@+id/home_gridview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#E4E4E4"
    android:cacheColorHint="#00000000"
    android:fadingEdge="none"
    android:horizontalSpacing="1dp"
    android:listSelector="#00000000"
    android:numColumns="3"
    android:scrollbars="none"
    android:verticalSpacing="1dp"
    ></menu.menudemo.ui.view.ZQScrollGridView>
