问题 I have a TabHost with 4-5 tabs. I want to have a similar bottom for all the tabs. Is there any way we can add a bottom to all the tabs? Or do I need to place the xml code in every layout file.

问题 I am trying to get an AdView directly below a TabHost. RelativeLayout does allow this to happen with android:layout_alignParentBottom="true" however this overlaps TabHost contents, and does so for the ScrollView's I add inside each Tab (this would probably occur for any views whose height was large enough) Right now the closest I can get to having a TabHost and AdView in their own seperate space on the screen is using this code (below), that allows me to have a Ad directly above the TabHost..
