Why my Admob banner is showing on top of screen?

Question

I have an app with two ads: a banner and an interstitial. I have a RelativeLayout where I have a GridLayout and the AdView. The grid layout has the line android:layout=above the AdView and the AdView has the line alignparentbottom="true" But it keeps showing the banner on top of the screen.

I need to place the AdView just at bottom of screen.

Answer 1

try adding a layout_gravity to your banner ad xml

<com.google.android.gms.ads.AdView
android:id="@+id/adView4"
android:layout_width="659dp"
android:layout_height="48dp"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:layout_marginTop="0dp"
ads:adSize="BANNER"
ads:adUnitId="ca-app-pub-2703074771097768/1520884519" />
