title: How can I add spacing in RelativeLayout
body: <p>I have a Relative Layout.
  Which has 2 buttons, side by side and it is right-aligned.  </p>
  
  <p>So this is my layout xml file.  My question is there are no spacing between the right-most button and the right border of the RelativeLayout and between the 2 buttons. How can I add that? I play with android:paddingRight, but nothing helps.</p>
  
  <p>Thank you.</p>
  
  <pre><code>&lt;RelativeLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingLeft="0dp" android:paddingRight="10dp"&gt;
  
      &lt;Button android:id="@+id/1button" android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_alignParentRight="true"
          android:paddingLeft="10dp" android:paddingRight="10dp"/&gt;
  
      &lt;Button android:id="@+id/1button" android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_toLeftOf="@id/1button"
          android:paddingLeft="10dp" android:paddingRight="10dp"/&gt;
  </code></pre>
