ScrollablePanel
感谢大神:https://github.com/Kelin-Hong/ScrollablePanel
A flexible view for providing a limited rect window into a large data set,just like a two-dimensional RecyclerView.
备注: 实际使用中,若数据很少,出现滑动卡顿Bug
Download
compile 'com.kelin.scrollablepanel:library:1.2.0'
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);
...
...
}
