ScrollView causes the App to crash

问题:

I'm testing the some of the sensors available, and i display the values of each sensor in a textview.

But When I enclosed all the textviews inside a scrollView the App crashed.

Note: my scrollView is already enclosed inside a linearLayout

Please find below the .xml file.
