  <p>How to do the same in relative layout?
  Here's the code: Trying linearlayout inside relative layout. But this doesn't work.</p>
  
  <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"

      &lt;LinearLayout
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:orientation="horizontal" &gt;
  
          &lt;Button
              android:id="@+id/button5"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
