–UPDATE– April 17th, 2012<\/p>\n
It seems that it is only crashing when I add:<\/p>\n
android:layout_above=\"@+id\/lakeSearchAdWebView\"\n<\/code><\/pre>\nto lakeSearchScrollView, adding it to just lakeSearchDetailsWebView works fine.<\/p>\n
Here’s my layout:<\/p>\n
\n\n\n\n\n \n\n \n\n \n\n \n \n\n \n\n \n \n \n\n\n\n\n\n\n\n<\/code><\/pre>\nI want to have lakeSearchScrollView and lakeSearchDetailsWebView setup so that they are always above lakeSearchAdWebview, so lakeSearchAdWebview is always visible. Only ONE of lakeSearchScrollView and lakeSearchDetailsWebView is visible at a time, that’s whey they’re setup to be sitting on top of eachother.<\/p>\n
If I add the following line to lakeSearchScrollView, the apps crashes:<\/p>\n
android:layout_above=\"@+id\/lakeSearchAdWebView\"\n<\/code><\/pre>\nCan anyone tell me what I’m doing wrong? I’m still quite new to Android so I’m thinking it’s probably a newbie mistake… thanks in advance!<\/p>\n

android:layout_above=”@+id\/lakeSearchAdWebView” means the view will be directly above lakeSearchAdWebView. Since you stated you put that in two different views, there is a problem, since they cannot both be directly above lakeSearchAdWebView.<\/p>\n
Therefore to fix, simply put: android:layout_above=\"@+id\/lakeSearchAdWebView\"<\/code> in the lakeSearchDetailsWebView<\/p>\nand then put android:layout_above:\"@+id\/lakeSearchDetailsWebView\"<\/code> in the lakeSearchScrollView<\/p>\nDoing it this way will have your views in the order (from top to bottom) lakeSearchScrollView, lakeSearchDetailsWebView, lakeSearchAdWebView<\/p>\n<\/li>\n<\/ol>\n
