Android 多個listview的實現

正好，今天項目中須要，先寫了個demo，給你們參考參考、

先上圖，須要的本身，看看具體的代碼實現步驟

 

大概說一下實現步驟：

1.佈局中先用 scrollview 包裹 LinearLayout

 1  <ScrollView
 2         android:id="@+id/scrollview"
 3         android:layout_width="fill_parent"
 4         android:layout_height="wrap_content"
 5         android:layout_below="@+id/relativeLayout1"
 6         android:fadingEdge="none"
 7         android:scrollbars="vertical">
 8 
 9         <LinearLayout
10             android:id="@+id/linearlayout"
11             android:layout_width="match_parent"
12             android:layout_height="fill_parent"
13             android:orientation="vertical">
14         </LinearLayout>
15     </ScrollView>

 

2.具體實現代碼
