Help with android layout? -

i have tablelayout , have ads on app, ads go under last button on screen, how can ad stick bottom of screen?

<textview  android:id="@+id/textview1"  android:layout_height="wrap_content" android:text="@string/time"  android:layout_width="wrap_content"> </textview>  <button  android:layout_height="wrap_content"   android:layout_centerinparent="true"    android:id="@+id/totime"  android:layout_width="wrap_content"> </button>  <button  android:layout_height="wrap_content"  android:text="save"  android:id="@+id/save"  android:layout_width="wrap_content"> </button>  <com.mobfox.sdk.mobfoxview 

android:id="@+id/mobfoxview" android:layout_width="fill_parent" android:layout_height="50dp" publisherid="**********" />

then, use relativelayout, , put like:

<com.mobfox.sdk.mobfoxview     android:id="@+id/mobfoxview"     android:layout_width="fill_parent"     android:layout_height="50dp"     android:layout_alignparentbottom="true"     publisherid="**********" /> 

you have modify widgets above mobfoxview... maybe can leave them inside tablelayout, , put tablelayout inside relativelayout:

<relativelayout>     <tablelayout>         other stuff     </tablelayout>     <mobfoxstuff/> </relativelayout>
