Paging Library without Room

Question

All examples of the new paging library have been with Room library and Room creates a Data Source for us. In my own case, I need to create my custom data source.

Here is

Answer 1

I think this can help:
1. countItems() should return DataSource.COUNT_UNDEFINED
2. loadRange(int startPosition, int count): You can directly execute your query.
3. So now you can delete result global variable

Also, turnoff placeholders:

listLiveData = p.create(0,new PagedList.Config.Builder()
        .setPageSize(5) //number of items loaded at once
        .setPrefetchDistance(10) //Must be >0 since placeholders are off
        .setEnablePlaceholders(false)
        .build());

Here is the updated code for Data Class:

public class DataClass extends TiledDataSource {

@Override
public int countItems() {
 return DataSource.COUNT_UNDEFINED;
}

@Override
public List loadRange(int startPosition, int count) {

 Call call = NetworkModule.providesWebService().makeRequest();
 Response response = call.execute();
 return parseJson(response.body());
}
