GetMeasuredHeight (), getScrollY (), getHeight (), getmeasuredheight

First, let's talk about getMeasuredHeight () and getHeight (). Both methods obtain the component height. In normal layout, if the component itself does not exceed the cell phone screen, the height obtained by these two methods is equal. However, in a sliding layout such as ScrollView, the height obtained by getHeight () is the height displayed on the screen, not exactly, it is the screen height. getMeasuredHeight () obtains the actual size of the component, including the displayed part and the part beyond the screen.

GetScrollY () indicates the sliding distance of ScrollView. The value obtained when sliding starts is 0.
