刚开始研究了下鸿蒙 HAP，然后~

摘一段代码：

public class ListItemProvider extends RecycleItemProvider {
    private ArrayList<String> data = new ArrayList<>();
    private AbilitySlice mSlice;

    ListItemProvider(AbilitySlice abilitySlice) {
        mSlice = abilitySlice;
        for (int i = 0; i < 10; ++i) {
            data.add("test" + i);
        }
    }

    @Override
    public long getItemId(int i) {
        return 0;
    }

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

    @Override
    public Component getComponent(int position, Component convertView, ComponentContainer parent) {
        Component component = LayoutScatter.getInstance(mSlice).parse(ResourceTable.Layout_list_item, null, false);
        if (!(component instanceof ComponentContainer)) {
            return null;
        }
        ComponentContainer rootLayout = (ComponentContainer) component;
        Text leftText = (Text) rootLayout.findComponentById(ResourceTable.Id_left_content);
        leftText.setText(String.valueOf(position));
        Text rightText = (Text) rootLayout.findComponentById(ResourceTable.Id_right_content);
        rightText.setText(data.get(position));
        return component;
    }
}

想起小学的时候。。。作业真的多啊

不论怎么说挺可以的了
