如何使活动可滚动？

Question

Some Buttons in my app are going to set my content View to a layout where is only 1 TextView and a Button. I want that my TextView becomming scroll-able but my button should be fixed, so he stands still on the top or on the buttom. At the moment I have ScrollView (see XMLCode below) but everytime I start it on my Android emulator, my app crashes if I click on the button so my layout with scrollview should show up. Every other layout is working but this one not.

Code doesn't appear correctly, here's the link .

I've used Linear and Relative layout as well, but I used ConstraintLayout on every layout so there it is as well.

Any ideas?

只需使用LinearLayout作为根布局，然后添加Button然后scrollview，然后在其中添加TextView

LinearLayout >> [ Button , ScrollView >> TextView ]
