Android jetpack，paging实现分页加载，LivePagedListProvider通过构造方法将PagedList与DataSource联系

kotlin：

val pagedListLiveData = PixabayDataSourceFactory(application).toLiveData(1)

Java：

PixabayDataSourceFactory pixabayDataSourceFactory = new PixabayDataSourceFactory(getApplication());
LiveData<PagedList<T>> pageListLiveData = new LivePagedListBuilder<>(
	pixabayDataSourceFactory,
	1
).build();
