Implementation of viewpager prohibiting sliding in Android

preface

In many apps, the home page does not allow sliding switching (because the page is loaded), but the viewpage is used to manage frgament. It's convenient

Examples previously found on the Internet:

This customization is OK if the inherited viewpager is a lower version

But if you compile with a higher version of API, after 5.0, the above customization will become invalid,

You will find that there will be slight sliding. It can still slide

To judge whether the old one is new, just look at setonpagechangelistener

This method in the latest viewpager has been abandoned and changed to addonpagechangelistener()

Because the viewpager was changed to lazy loading before, an old version of viewpager has been retained. It was not found until recently

After improvement
