Table Layout Alignment?

Question

I have designed an XML layout as in this image:

I need to equally place the four buttons in the screen but I am having trouble getting it to work. I tried all possible changes that I can think of. Below is the layout's XML:

<RelativeLayout  
   android:layout_width="fill_parent"  
   android:layout_height="40dp" 
   android:id="@+id/buttonlayout"
   android:layout_alignBottom="@id/framelayout">


<TableLayout 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
xmlns:android="http://schemas.android.com/apk/res/android">

<TableRow>

  <Button
    android:id="@+id/previous"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/previous_icon" />

 <Button
    android:id="@+id/button_startprint"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/print_icon"
    android:padding="10dp" />

<Button
    android:id="@+id/button_cam"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/cam_icon"
    android:padding="10dp" />

<Button
    android:id="@+id/next"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/next_icon"
    android:hapticFeedbackEnabled="true"/>

 </TableRow>  
 </TableLayout> 
</RelativeLayout> 

Can anyone help me out with this?
