Android Viewpager Change Adapter----When you use Viewpager to set a new adapter, you find the page or show the values in the old adapter

One requirement is that when a user chooses an item in the Navigationview, the Viewpager on the right needs to dynamically switch between the different adapter

Found direct setadapter without any response, loaded data or old data

Toss for half a day just to be

Fragmentpageradapter, change to Fragmentstatepageradapter.
Specific Baidu the difference between, there is time I write a summary out
The approximate understanding:

Fragmentpageradapter caches multiple data, and the data in the Viewpager does not change frequently

Fragmentstatepageradapter does not cache data, it is destroyed every time, and is suitable for dynamic changes
