Margin does not impact in "include"

I have a view with articles. It uses "include", and I'm trying to make a little margin between them. However, "android:layout_marginTop" does not seem to have any impact on the layout.

What am I doing wrong?

<LinearLayout 
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >    
    <include android:id="@+id/article1" layout="@layout/mainarticle" />
    <include android:id="@+id/article2" android:layout_marginTop="10dip" layout="@layout/article" />
    <include android:id="@+id/article3" android:layout_marginTop="10dip" layout="@layout/article" />
    <include android:id="@+id/article4" android:layout_marginTop="10dip" layout="@layout/article" />
    <include android:id="@+id/article5" android:layout_marginTop="10dip" layout="@layout/article" />    
</LinearLayout>

You should add the android:layout_width and android:layout_height attributes in the include tag. Otherwise, the margins are not taken into consideration.

However, if you want to override layout attributes using the <include> tag, you must override both android:layout_height and android:layout_width in order for other layout attributes to take effect.

I had the same problem and the answer from Kamen Goranchev doesn't work for me.

I have used ADT's feature "Extract include..." from the layout editor to extract some commonly used badges as a list of TextView-elements. So the Extract-include-tool wrapped my TextView-Elements in a merge-tag, which usually would be fine.

But, according to the very helpful sourcecode-link from boiledwater I see in line 888 https://github.com/android/platform_frameworks_base/blob/master/core/java/android/view/LayoutInflater.java#L888, the layout-attributes from the include-tag itself are only parsed if the include doesn't have the merge-tag as its root-element.

So I removed the merge-tag from the include and used another ViewGroup-tag like e.g. FrameLayout. Then the margins in the include-tag are working as expected.


include tag support below properties:

  1. Any android:layout_* attributes which you can overwrite.

  2. android:id attribute.

  3. layout attribute.
  4. android:visibility attribute.

Etc: include android:id=”@+id/news_title” android:layout_width=”match_parent” android:layout_height=”match_parent” layout=”@layout/title”/>

Another solution would be to add Space before include:

    <Space
        android:layout_height="8dp"
        android:layout_width="match_parent" />
