Hi use this may be it's solve your problem:

android:windowSoftInputMode="adjustPan" in your manifest file in activity

second:

android:gravity="bottom" set in LinearLayout 

<LinearLayout android:id="@+id/bottom_control_bar" 
android:layout_marginTop="8dp" android:orientation="horizontal" 
android:layout_width="fill_parent" android:gravity="bottom"
android:layout_height="wrap_content" android:layout_alignParentBottom="true">               
    <com.google.ads.AdView android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ads:adUnitId="xcxxxcxcxc"
    ads:adSize="BANNER"
    ads:loadAdOnCreate="true">
 </com.google.ads.AdView>
</LinearLayout>
