Android Scrollview: Scrollview

When there are so many contents on the user interface provided by activity that the current mobile phone screen cannot fully display all the contents, you need to scroll the view to help browse all the contents.

The effect is shown in Figure 1.

At this time, you need to use Scrollview to convert the current activity view into a scrolling view for easy browsing. The use of Scrollview is very convenient.

After adding Scrollview, the operation effect of the main.xml layout is shown in Figure 2.
