ScrollView with CardView does not work

I want to use a ScrollView to put in a CardView and a vertical button, I made this XML and if it compiles, but when it is time to test it on a device, the app closes immediately. The device on which I am doing the test is API 22:

<?xml version="1.0" encoding="utf-8"?>

<TextView
    android:layout_width="wrap_content"

This is my gradle file:
