RecyclerPagerAdapter

RecyclerPagerAdapter is a class that extends PagerAdapter to offer a RecyclerView.Adapter-like interface with a couple of convenience parameters and methods. Like RecyclerView and unlike, PagerAdapter, RecyclerPagerAdapter handles view recycling through the ViewHolder pattern

Install

Add the following line to your module's build.gradle dependencies to use:

compile 'com.nyentek.android:recyclerpageradapter:1.x.y'

Usage

Extend RecyclerPagerAdapter<Item, ViewHolder extends RecyclerPagerAdapter.ViewHolder> filling in the generic types to fit your app-specific data and view.

`ExamplePagerAdapter`

public class ExamplePagerAdapter extends RecyclerPagerAdapter<String, ExampleViewHolder> {

    private List<String> stringList;

    public ExamplePagerAdapter(List<String> stringList) {
        this.stringList = stringList;
    }

    @Override
    public int getCount() {
        return stringList; // size of items in data set
    }

    @Override
    public String getItem(int position) {
        return stringList.get(position); // return an item at given position in data set
    }

    @Override
    public int getItemViewType(int position) {
        return 0; // return unique integer to represent a view type, 0 in this example for one view type
    }

    @Override
    public ExampleViewHolder onCreateViewHolder(LayoutInflater inflater, ViewGroup parent, int viewType) {
        // use viewType if more than one view type to determine what subclass of ExampleViewHolder to return
        // in this example, there is only one view type so no need to use viewType or subclass
        return new ExampleViewHolder(inflater.inflate(R.layout.page_example, parent, false));
    }

    @Override
    public void onBindViewHolder(DemoRecyclerPagerAdapterViewHolder holder, String text) {
        holder.setText(text);
    }
}

`ExampleViewHolder`

public class ExampleViewHolder extends RecyclerPagerAdapter.ViewHolder {

    private TextView textView;

    public DemoRecyclerPagerAdapterViewHolder(View view) {
        super(view);
        textView = (TextView) view;
    }

    public void setText(String text) {
        textView.setText(text);
    }
}

`page_example.xml`

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="match_parent"
          android:layout_height="match_parent" />
