组图模块

使用ListView与GridView切换：

实现效果：

整体XML布局：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    android:orientation="vertical" >
    <ListView 
        android:id="@+id/lv_menu_groupphoto_listView"
        android:layout_width="match_parent"
    	android:layout_height="match_parent"
    	android:divider="@null"
    	android:textAlignment="1"
    	
        />
    <GridView 
        android:id="@+id/gv_menu_groupphoto_gridview"
        android:layout_width="match_parent"
    	android:layout_height="match_parent"
    	android:numColumns="2"
        ></GridView>

    
</FrameLayout>

局部布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <LinearLayout 
         android:layout_width="match_parent"
    	 android:layout_height="match_parent"
    	 android:orientation="vertical"       
        >
        <ImageView 
            android:id="@+id/iv_list_groupphoto_ImageView"
            android:layout_width="match_parent"
    	 	android:layout_height="0dp"  
    	 	android:layout_weight="5"     
    	 	android:src="@drawable/ic_launcher"      
            />
        <TextView 
            android:id="@+id/tv_list_groupphoto_TextView"
            android:layout_width="match_parent"
    	 	android:layout_height="0dp"  
    	 	android:layout_weight="1"
    	 	android:text="this is a textview"
    	 	android:gravity="center"
    	 	android:textSize="22sp"
            />
    </LinearLayout>
</LinearLayout>

实现代码：

可分为 绘图， 从网络获取数据，以及数据解析，太简单，无力写注释。。。。
