title: Is there a way to completely eliminate padding in a LinearLayout containing buttons?
body: <p>I tried the following to try to display two buttons in a horizontal linear layout, with the edges of the buttons flush with the border of the linear layout.  To my surprise, I found that there is always still padding between the buttons and the left, right and bottom edges of the linear layout.  Only the top edges of the buttons end up flush with the border of the linear layout.  Why is that?  And is there a way to control this behavior?  Thanks much. </p>
  
  <pre><code>&lt;LinearLayout android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#777"
    android:padding="0dip"
    android:layout_margin="0dip"&gt;
    &lt;Button android:id="@+id/feeling_done_button"
       android:text="@string/done_button_label"
       android:layout_height="wrap_content"
       android:layout_width="match_parent"
       android:layout_weight="1"
       android:padding="0dip"
       android:layout_margin="0dip"/&gt;
    &lt;Button android:id="@+id/feeling_cancel_button"
       android:text="@string/cancel_button_label"
       android:layout_height="wrap_content"
       android:layout_width="match_parent"
       android:layout_weight="1"
       android:padding="0dip"
       android:layout_margin="0dip"/&gt;&lt;/LinearLayout&gt;
