Hello,

condition i need to change android:layout_below instead of android:layout_below="@id/title1" change to android:layout_below="@id/title2"

Do you want to change it at runtime in the background code?

If so, you can use  relativeLayoutLayoutParams.AddRule(LayoutRules.Below, Resource.Id.title2); to set it.

RelativeLayout.LayoutParams relativeLayoutLayoutParams = new RelativeLayout.LayoutParams(Android.Views.ViewGroup.LayoutParams.MatchParent, Android.Views.ViewGroup.LayoutParams.WrapContent);

relativeLayoutLayoutParams.AddRule(LayoutRules.Below, Resource.Id.title2);
relativeLayoutLayoutParams.SetMargins(0, 4, 0, 0);
listView.LayoutParameters = relativeLayoutLayoutParams;

Please Note:If you have some controls below or above the listView, you need to AddRule for all of them.
