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：

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

作为LinearLayout的Divider属性引入：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:divider="@drawable/spacer_medium"
    android:orientation="vertical"
    android:padding="@dimen/spacing_medium"
    android:showDividers="middle">

    <!-- TextView -->

    <LinearLayout
        android:id="@+id/buttons_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:divider="@drawable/spacer_medium"
        android:orientation="horizontal"
        android:showDividers="middle">

        <!-- Buttons -->

    </LinearLayout>

</LinearLayout>
