How to make scrollview extend beyond screensize android?

Question

My root element is relative layout, within which I have one LinearLayout wrapped into a scrollview. The LinearLayout has multiple children that include textViews, editText, and other Linearlayouts that have textviews and editText. Looked into several SO posts, but no help. All I get is a grey bar on the right of the screen,which scrolls just an inch max, can't scroll any further down.The last few components are only half visible and scrolling does not happen until the bottom where my last components are visible. Setting the viewport parameter to true/false has no effect. Any help will be appreciated.

Answer 1

Your layout structure is fine. The problem is you are setting a specified height for almost everything, that's a no no. If you want to work with font height, there's a property called

android:textSize

in all views related to text, and the preferred unit is sp for text, dp for images.

Change all heights to

wrap_content
