Android Shape Divider

安卓框架提供了一种LinearLayout 内部布局元素分割线的实现，建立一个指定长宽的矩形Shape：

 1  <?xml version="1.0" encoding="utf-8"?>
 2  <shape xmlns:android="http://schemas.android.com/apk/res/android"
 3      android:shape="rectangle">
 4  5      <size
 6         android:width="@dimen/spacing_medium"
 7         android:height="@dimen/spacing_medium" />
 8  9     <solid android:color="@android:color/transparent" />
10 11 </shape>

作为LinearLayout的Divider属性引入：

 1 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     android:layout_width="match_parent"
 3     android:layout_height="wrap_content"
 4     android:divider="@drawable/spacer_medium"
 5     android:orientation="vertical"
 6     android:padding="@dimen/spacing_medium"
 7     android:showDividers="middle">
 8 
 9     <!-- TextView -->
10 
11     <LinearLayout
12         android:id="@+id/buttons_container"
13         android:layout_width="match_parent"
14         android:layout_height="wrap_content"
15         android:divider="@drawable/spacer_medium"
16         android:orientation="horizontal"
17         android:showDividers="middle">
18 
19         <!-- Buttons -->
20 
21     </LinearLayout>
22 
23 </LinearLayout>
