Divider issue in android xml layout

Question

My goal is to get the layout like the sample about. However, I can't get the small line above the button bar.

What I get is like this.

my xml code is :

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

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="18dp"
    android:layout_marginRight="18dp"
    android:layout_marginTop="24dp"
    >

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

    <TextView
        style="?android:listSeparatorTextViewStyle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Section header"/>

    <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 1"
          android:layout_gravity="center_vertical"/>

      <ImageButton
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:src="@drawable/ic_action_discard"
          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:layout_width="wrap_content"
          android:layout_height="wrap_content"
          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. However, if I use LinearLayout the divider will show right under Sample item 2, which is not what I want.

So how can I get what the sample shows?

Answer 1

Add an extra View to your layout which will take no height as below...

<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...

<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>

Finally, your layout will be...

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="18dp"
    android:layout_marginRight="18dp"
    android:layout_marginTop="24dp" >

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

        <TextView
            style="?android:listSeparatorTextViewStyle"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Section header" />

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

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

            <ImageButton
                style="?android:borderlessButtonStyle"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/ic_launcher" />
        </LinearLayout>

        <LinearLayout

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

                android:layout_height="wrap_content"
                android:src="@drawable/ic_launcher" />
        </LinearLayout>
    </LinearLayout>

    <LinearLayout

        android:divider="?android:dividerHorizontal"
        android:orientation="vertical"

check this below layout. I've made few changes to add the horizontal divider above ButtonBarLayout.

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.
