my xml code is : 我的xml代码是： 

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout

        android:orientation="horizontal"
        android:baselineAligned="false"
        android:showDividers="middle"
        android:divider="?android:dividerVertical"
        android:dividerPadding="8dp">

      <TextView

          android:layout_height="wrap_content"
          android:layout_weight="1"
          android:textAppearance="?android:textAppearanceMedium"
          android:text="Sample item 1"

          style="?android:borderlessButtonStyle"/>

    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:baselineAligned="false"
        android:showDividers="middle"
        android:divider="?android:dividerVertical"
        android:dividerPadding="8dp">

      <TextView
          android:layout_width="0dp"
          android:layout_height="wrap_content"
          android:layout_weight="1"
          android:textAppearance="?android:textAppearanceMedium"
          android:text="Sample item 2"
          android:layout_gravity="center_vertical"/>

      <ImageButton

          android:src="@drawable/ic_action_discard"
          style="?android:borderlessButtonStyle"/>

    </LinearLayout>

  </LinearLayout>

  <LinearLayout
      android:id="@+id/buttonBarLayout"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_alignParentBottom="true"
      android:orientation="horizontal"
      style="?android:buttonBarStyle"
      >

    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Discard"
        style="?android:buttonBarButtonStyle"/>

    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Save"
        style="?android:buttonBarButtonStyle"/>

  </LinearLayout>

</RelativeLayout>

I believe that the line is the middle divider. 我相信这条线是中间分隔线。 However, if I use LinearLayout the divider will show right under Sample item 2, which is not what I want. 但是，如果我使用LinearLayout，分隔符将显示在示例项2下，这不是我想要的。

So how can I get what the sample shows? 那么我怎样才能得到样本显示的内容？

Add an extra View to your layout which will take no height as below... 在您的布局中添加一个额外的View ，其height不会低于以下... 

<View
    android:layout_width="match_parent"
    android:layout_height="0dip" />

Then add the above View and the Linearlayout which holding Buttons inside another LinearLayout with android:divider="?android:dividerHorizontal" attribute as below... 然后添加上面View和Linearlayout持有本Buttons另一个内部LinearLayout与android:divider="?android:dividerHorizontal"属性如下... 

<LinearLayout
    android:id="@+id/buttonBarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:divider="?android:dividerHorizontal"
    android:orientation="vertical"
    android:showDividers="middle" >

    <View
        android:layout_width="match_parent"
        android:layout_height="0dip"
        android:background="#000000" />

    <LinearLayout
        style="?android:buttonBarStyle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:divider="?android:dividerHorizontal"
        android:orientation="horizontal" >

        <Button
            style="?android:buttonBarButtonStyle"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Discard" />

        <Button
            style="?android:buttonBarButtonStyle"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Save" />
    </LinearLayout>

</LinearLayout>

check this below layout. 检查下面的布局。 I've made few changes to add the horizontal divider above ButtonBarLayout. 我做了一些更改，在ButtonBarLayout上面添加水平分隔符。

You have to give the id to the Linear layout above the button linear layout and place the view in between the button linear layout and linear layout above it. 您必须将id放在按钮线性布局上方的线性布局中，并将视图放在按钮线性布局和其上方的线性布局之间。
