3 | [![Build Status](https://travis-ci.com/nekocode/Items.svg?branch=master)](https://travis-ci.com/nekocode/Items) [![codecov](https://codecov.io/gh/nekocode/Items/branch/master/graph/badge.svg)](https://codecov.io/gh/nekocode/Items) 4 | 5 | 这个库可以为 Android 的 `RecyclerView` 生成基于 **Data-View-Binding** 的 Adapter。 6 | 7 | 对比其他一些类似的开源库，它有以下的一些优势： 8 | * 更好的拓展性。这个库不需要你继承特定的 Adapter 或 ViewHolder 类，你可以继承任何第三方提供的基类； 9 | * 更好的性能。使用 Annotation Processor 意味着实现 Binding 时无需使用反射。支持 [增量处理](https://docs.gradle.org/current/userguide/java_plugin.html#sec:incremental_annotation_processing)； 10 | * 更低的侵入性。和传统的 Adapter 写法类似，可以快速从旧的 Codebase 迁移到新的写法； 11 | * 更可靠的代码。提供了单元测试覆盖大部分的 Case。 12 | 13 | ## 集入 14 | 15 | 替换以下代码中的 `${lastest-version}` 为最新版本号 [![](https://jitpack.io/v/nekocode/Items.svg)](https://jitpack.io/#nekocode/Items)，并复制到 Android 工程中的 build.gradle 脚本: 16 | 17 | ```gradle 18 | repositories { 19 | maven { url "https://jitpack.io" } 20 | } 21 | dependencies { 22 | implementation "com.github.nekocode.Items:itemsLib:${lastest-version}" 23 | annotationProcessor "com.github.nekocode.Items:itemsProcessor:${lastest-version}" 24 | } 25 | ``` 26 | 27 | 注意，在 Kotlin 工程中，需要使用 `kapt` 关键字代替 `annotationProcessor` 关键字。 28 | 29 | ## 使用 30 | 31 | 使用 `BaseItem` 能够帮助你把 `ViewHolder` 的创建和绑定从 Adapter 中提取出来，并且与特定的数据类型绑定。例如你可以为 `String` 类型的数据创建一个 Item： 32 | 33 | ```java 34 | public class StringItem extends BaseItem { 35 | 36 | public StringItem(ItemAdapter adapter, int viewType) { 37 | super(adapter, viewType); 38 | } 39 | 40 | @NonNull 41 | @Override 42 | public Holder onCreateViewHolder(@NonNull LayoutInflater inflater, @NonNull ViewGroup parent) { 43 | final View itemView = inflater.inflate(R.layout.item_string, parent, false); 44 | final Holder holder = new Holder(itemView); 45 | holder.button.setOnClickListener(v -> { 46 | if (getCallback() != null) { 47 | getCallback().onButtonClick(holder.data); 48 | } 49 | }); 50 | return holder; 51 | } 52 | 53 | @Override 54 | public void onBindViewHolder(@NonNull Holder holder, int position, @NonNull String data) { 55 | holder.data = data; 56 | holder.textView.setText(data); 57 | } 58 | 59 | static class Holder extends RecyclerView.ViewHolder { 60 | private TextView textView; 61 | private Button button; 62 | private String data; 63 | 64 | Holder(View itemView) { 65 | super(itemView); 66 | textView = itemView.findViewById(R.id.textView); 67 | button = itemView.findViewById(R.id.button); 68 | } 69 | } 70 | 71 | public interface Callback { 72 | void onButtonClick(@NonNull String data); 73 | } 74 | } 75 | ``` 76 | 77 | Item 提供了很好的拓展能力： 78 | * 可以使用任意类型的 `ViewHolder`； 79 | * 可以通过 `Callback` 为 `ViewHolder` 设置 UI 事件回调。 80 | 81 | 接下来你需要创建一个 Adapter 来装载你的所有 Item： 82 | 83 | ```java 84 | @AdapterClass 85 | public abstract class TestAdapter extends RecyclerView.Adapter implements ItemAdapter { 86 | private final LinkedList mList = new LinkedList(); 87 | 88 | @NonNull 89 | public LinkedList list() { 90 | return mList; 91 | } 92 | 93 | @Override 94 | public int getItemCount() { 95 | return mList.size(); 96 | } 97 | 98 | @NonNull 99 | @Override 100 | public T getData(int position) { 101 | return (T) mList.get(position); 102 | } 103 | 104 | /** 105 | * 定义一个任意名称的方法来返回你想装载的 Item 106 | */ 107 | @NonNull 108 | @ItemMethod 109 | public abstract StringItem stringItem(); 110 | } 111 | ``` 112 | 113 | 这个 Adapter 必须实现 `ItemAdapter` 接口的 `getItemCount()` 和 `getData()` 方法。你可以使用任意类型的 Collection（例如上面的 `LinkedList`）来装载你的数据，这个 Adapter 会通过这两个方法来访问你的数据，然后根据数据的类型来选择对应的 Item 来创建 `ViewHolder`。 114 | 115 | 在编译期间，Annotation Processor 会为这个 Adapter 生成一个实现类 `TestAdapterImpl`，你可以通过以下例子来使用这个 Adapter： 116 | 117 | ```java 118 | // 创建 Adapter 实例 119 | TestAdapter adapter = new TestAdapterImpl(); 120 | 121 | // 给 Adapter 插入数据 122 | adapter.list().add("Item1"); 123 | adapter.list().add("Item2"); 124 | 125 | // 给 Item 设置 Callback 126 | adapter.stringItem().setCallback(data -> { 127 | // Button 点击时 128 | }); 129 | 130 | // 为 RecyclerView 设置 Adapter 131 | recyclerView.setAdapter(adapter); 132 | ``` 133 | 134 | 以上就是这个工具的基础使用。 135 | 136 | 此外，你还可以让你的单个数据类型绑定多个 Item： 137 | 138 | ```java 139 | @Adapter 140 | public abstract class TestAdapter extends RecyclerView.Adapter implements ItemAdapter { 141 | // ... 142 | 143 | @NonNull 144 | @ItemMethod 145 | public abstract StringItem stringItem(); 146 | 147 | @NonNull 148 | @ItemMethod 149 | public abstract StringItem2 stringItem2(); 150 | 151 | /** 152 | * 定义一个任意名称的方法来帮助 Adapter 选择绑定了同一数据类型的 Item 153 | */ 154 | @SelectorMethod 155 | public int itemForString(int position, @NonNull String data) { 156 | if (!data.endsWith(2)) { 157 | return stringItem().getViewType(); 158 | } else { 159 | return stringItem2().getViewType(); 160 | } 161 | } 162 | } 163 | ``` 164 | 165 | 最后，还有一个小的 Tip。你可以定义一些 BaseAdapter 来简化你 Adapter 的代码，例如把对集合的操作封装起来，举个例子： 166 | 167 | ```java 168 | public abstract class BaseArrayListAdapter extends RecyclerView.Adapter implements ItemAdapter { 169 | private final ArrayList mList = new ArrayList(); 170 | 171 | public ArrayList getList() { 172 | return mList; 173 | } 174 | 175 | @NonNull 176 | @Override 177 | public T getData(int position) { 178 | return (T) mList.get(position); 179 | } 180 | 181 | @Override 182 | public int getItemCount() { 183 | return mList.size(); 184 | } 185 | } 186 | 187 | @Adapter 188 | public abstract class TestAdapter extends BaseArrayListAdapter { 189 | // ... 190 | } 191 | ``` 192 | 193 | 更详细的应用可以参考这个仓库中的 [exampleApp](exampleApp) 模块。 194 | -------------------------------------------------------------------------------- /build.gradle:
