Android Scrollview in a RelativeLayout Shows Blank

i'm trying to make that all the content i have in a view can be scroll-able and what i'm doing is adding a Scrollview to the entire relative layout but when i do this anything is shown in the view. Below is the layout code i have with the Scrollview.

<Scrollview
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scroller"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

i found a solution through the use of an unusual method that was provided by doughw. The solution is to hack the listview to load to a full height.

Here is the link to the answer: How can I put a ListView into a ScrollView without it collapsing?

Thanks everybody.

I had an issue close to what you had and my problem was using layout_width="match_parent" on items that were aligned to the left or right of another item. I changed it to layout_width="wrap_content" and everything worked perfectly after that.

Change the wrap_content to fill_parent in the scrollview height attribute.
