Usage

ScrollablePanel is very similar to the RecyclerView and we can use them in the same way.

####1、Initialize ScrollablePanel

<com.kelin.scrollablepanel.library.ScrollablePanel
        android:id="@+id/scrollable_panel"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

####2、Adapter

This adapter must extend a class called PanelAdapter,We now have to override following methods so that we can implement our logic.

public class TestPanelAdapter extends PanelAdapter {
    private List<List<String>> data;

    @Override
    public int getRowCount() {
        return data.size();
    }

    @Override
    public int getColumnCount() {
        return data.get(0).size();
    }

    @Override
    public int getItemViewType(int row, int column) {
        return super.getItemViewType(row, column);
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int row, int column) {
        String title = data.get(row).get(column);
        TitleViewHolder titleViewHolder = (TitleViewHolder) holder;
        titleViewHolder.titleTextView.setText(title);
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new TestPanelAdapter.TitleViewHolder(LayoutInflater.from(parent.getContext())
                .inflate(R.layout.listitem_title, parent, false));
    }

    private static class TitleViewHolder extends RecyclerView.ViewHolder {
        public TextView titleTextView;

        public TitleViewHolder(View view) {
            super(view);
            this.titleTextView = (TextView) view.findViewById(R.id.title);
        }
    }
}

####3、Set Adapter

@Override
protected void onCreate(Bundle savedInstanceState) {
   ...
   ...
   TestPanelAdapter testPanelAdapter = new TestPanelAdapter();
   ScrollablePanel scrollablePanel = (ScrollablePanel) findViewById(R.id.scrollable_panel);
   scrollablePanel.setPanelAdapter(testPanelAdapter);
   ...
   ...
}
