android动态设置配置项并随机排布并实现多选

效果如下：

首先布局是这样的，只有一个自定义的控件的FlowLayout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >


    <com.example.zza_android_test7.FlowLayout
        android:id="@+id/flow"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </com.example.zza_android_test7.FlowLayout>


</RelativeLayout>

活动页面，实现了两种方法
