critical code

1. Listen for scrolling events

First, add setonscrolllistener listener to listview. Note that this listener is addonscrolllistener on recyclerview, that is, the following code supports recyclerview at the same time.

There are two methods in monitoring. We use onscroll method to record the current first visible item and the total number of visible items, and use onscrollstatechanged to monitor the whole process of hand sliding the screen. When the scrollstate field value in onscrollstatechanged is equal to scroll_ STATE_ When idle, it means that the sliding is completed and the rolling is stopped 🙄 Interested friends can Baidu the meaning of the other two parameters, which may be helpful to your needs 🙄。

2. Processing video logic

First, judge whether the item has video according to the total number. If so, use the rect class to obtain the visual area of the view in the screen coordinates.
