1. In ScrollView, when the scroll bar is in a certain location, if the current view is changed, the current focus position is incorrect?
Workaround: Use the setscrollpos function to reset the focus position
2, in ScrollView, when there is no dual cache, the focus position on the screen is not normal when dragging the scroll bar?
Workaround: Use the setWindoworg (X-axis roller position, Y scroll bar position) function to solve this bit
