When making a product, there is a need to monitor the ScrollView slide to the bottom. On the Internet to find some methods, there are such or that the problem, or the monitoring is not accurate,Or the repetitive monitoring, the code is not product, very unreliable.After their own experiments, finally found a capable of accurate monitoring of the implementation method. The code is as follows:1 Public classScrollbottomscrollviewextendsScrollView {2 3 PrivateOnscrollbottomlistener _listener;4

I used to have a headache for this problem for a long time. And then went to work on other things. Have not been to tidy up, today very difficult to idle down.
