RecyclerView

前端之家收集整理的这篇文章主要介绍了RecyclerView前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

RecyclerView

项目地址: RecyclerView
简介:支持下拉刷新,下拉加载,Header,Footer,复杂多种数据结构
  • RecyclerAdapter : 支持下拉刷新,上拉加载,添加 Header,Footer
  • MultiTypeAdapter : 针对复杂数据类型的数据列表

使用方法

  • gradle 依赖
compile 'cn.lemon:RefreshRecyclerView:0.1.5'
<cn.lemon.view.RefreshRecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:refresh_able="true"
        app:load_more_able="false"/>
mRecyclerView = (RefreshRecyclerView) findViewById(R.id.recycler_view);
   mRecyclerView.setSwipeRefreshColors(0xFF437845,0xFFE44F98,0xFF2FAC21);
   mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
   mRecyclerView.setAdapter(mAdapter);
   mRecyclerView.setRefreshAction(new Action() {
        @Override
        public void onAction() {
            getData(true);
        }
   });

   mRecyclerView.setLoadMoreAction(new Action() {
        @Override
        public void onAction() {
            getData(false);
            page++;
        }
   });
   mAdapter.setHeader(textView); //添加 Header
   mAdapter.setFooter(footer); //添加 Footer

RecyclerAdapter

针对相同数据类型列表,可添加 Header,Footer

自定义 Adapter 应该继承 RecyclerAdapter,如:

class CardRecordAdapter extends RecyclerAdapter<Consumption> {

    public CardRecordAdapter(Context context) {
        super(context);
    }

    @Override
    public BaseViewHolder<Consumption> onCreateBaseViewHolder(ViewGroup parent,int viewType) {
        return new CardRecordHolder(parent);
    }
}

MultiTypeAdapter

复杂数据类型列表,没有 Header,Footer 的概念,每个 Item 对应一个 ViewHolder

private MultiTypeAdapter mAdapter;
 mAdapter.add(ImageViewHolder.class,getImageVirtualData());
 mAdapter.addAll(TextViewHolder.class,getTextVirtualData());
 mAdapter.addAll(TextImageViewHolder.class,getTextImageVirualData());
 mAdapter.addAll(CardRecordHolder.class,getRecordVirtualData());

ViewHolder

自定义 ViewHolder 需继承 BaseViewHolder,如:

class CardRecordHolder extends BaseViewHolder<Consumption> {

     //当使用 MultiTypeAdapter 时,务必加上此构造方法
     public CardRecordHolder(ViewGroup parent) {
         super(parent,R.layout.holder_consume);
     }

     @Override
     public void setData(Consumption object) {
         super.setData(object);
         name.setText("Demo");
         //UI 绑定数据
     }

     @Override
     public void onInitializeView() {
         super.onInitializeView();
         name = findViewById(R.id.name);
         //初始化 View
     }

     @Override
     public void onItemViewClick(Consumption object) {
         super.onItemViewClick(object);
         //点击事件
     }
 }

注意:MultiTypeAdapter 的 ViewHolder 的构造函数保证能反射时获取,应该写成静态或者 public 的单独类

详细用法请看 Demo



注意事项

  • 依赖了其他库
compile 'com.android.support:recyclerview-v7:23.4.0'
    compile 'com.android.support:support-annotations:23.4.0'
