title: Android TableRow positioning
body: <p>i want to make a kind of weapon selector for my game. It will consisted of a left arrow, the weapon image, and a right arrow.</p>
  
  <p>My approach is like this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent" android:layout_height="fill_parent"
  android:orientation="vertical"&gt;
  &lt;TableRow android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:gravity="bottom" android:orientation="horizontal"&gt;
      &lt;ImageView android:layout_width="wrap_content"
          android:layout_height="wrap_content" android:src="@drawable/larrow"
          android:id="@+id/img_larrow" /&gt;
      &lt;ImageView android:layout_height="wrap_content"
          android:layout_width="wrap_content" android:src="@drawable/ak47"
          android:id="@+id/img_ak47" /&gt;
      &lt;ImageView android:layout_width="wrap_content"
          android:layout_height="wrap_content" android:src="@drawable/rarrow"
          android:id="@+id/img_rarrow" /&gt;
  &lt;/TableRow&gt;
  </code></pre>
  
  <p></p>
  
  <p>The problem is, I want to make it position on the bottom-center. So far I just can make it position on the bottom or top center via the TableRow's android:gravity attribute. There is "bottom" and "center_horizontal" attribute for android:gravity but none for bottom center. Anyone know how to do this?</p>
