#### 安装教程
1.在项目根目录下的build.gradle文件中，

```groovy
// 添加maven仓库
repositories {
    maven {
        url 'https://s01.oss.sonatype.org/content/repositories/releases/'
    }
}
 ```
 2.在entry模块的build.gradle文件中，
 ```groovy
// 添加依赖库
dependencies {
    implementation 'com.gitee.chinasoft_ohos:expandable-recycler-view:1.0.0'
}

 ```

在sdk6，DevEco Studio2.2 beta1下项目可直接运行
如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，
并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

#### 使用说明

添加布局
``` xml
        <com.thoughtbot.expandablecheckrecyclerview.expand.ExpandListContainer
            ohos:id="$+id:list_container"
            ohos:height="match_parent"
            ohos:width="match_parent"
            />

         <com.thoughtbot.expandablecheckrecyclerview.multicheck.MuCheckContainer
            ohos:id="$+id:list_container"
            ohos:height="match_parent"
            ohos:width="match_parent" />

        <com.thoughtbot.expandablecheckrecyclerview.multitype.MultiTypeContainer
            ohos:id="$+id:multiType_container"
            ohos:height="match_parent"
            ohos:width="match_parent" />   

         <com.thoughtbot.expandablecheckrecyclerview.multitypeandcheck.MultiTypeAndCheckContainer
            ohos:id="$+id:multiType_container"
            ohos:height="match_parent"
            ohos:width="match_parent" />

        <com.thoughtbot.expandablecheckrecyclerview.singlecheck.SingleCheckContainer
            ohos:id="$+id:list_container"
            ohos:height="match_parent"
            ohos:width="match_parent" />
```
创建对象并设置参数

**相关方法:**
* **setFatherData** 设置父菜单数据
* **setChildData**  设置子菜单数据

```java
   private void initView() {
        listContainer = (MultiTypeAndCheckContainer)findComponentById(ResourceTable.Id_multiType_container);
        listContainer.setFatherData(getData());
        listContainer.setChildData(getChildMap());
        backButton = (Button)findComponentById(ResourceTable.Id_backButton);
        backButton.setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                terminateAbility();
            }
        });
    }

    private List<ExpandFatherItem> getData() {
        ArrayList<ExpandFatherItem> data = new ArrayList<>();
        VectorElement vectorElementLabel = new VectorElement(getContext(),ResourceTable.Graphic_ic_arrow_down);
        VectorElement vectorElementRock = new VectorElement(getContext(),ResourceTable.Graphic_ic_electric_guitar);
        VectorElement vectorElementJazz = new VectorElement(getContext(),ResourceTable.Graphic_ic_saxaphone);
        VectorElement vectorElementClassic = new VectorElement(getContext(),ResourceTable.Graphic_ic_violin);
        VectorElement vectorElementSalsa = new VectorElement(getContext(),ResourceTable.Graphic_ic_maracas);
        VectorElement vectorElementBluegrass = new VectorElement(getContext(),ResourceTable.Graphic_ic_banjo);
        data.add(new ExpandFatherItem("0",vectorElementRock,"Rock",vectorElementLabel));
        data.add(new ExpandFatherItem("1",vectorElementJazz,"Jazz",vectorElementLabel));
        data.add(new ExpandFatherItem("2",vectorElementClassic,"Classic",vectorElementLabel));
        data.add(new ExpandFatherItem("3",vectorElementSalsa,"Salsa",vectorElementLabel));
        data.add(new ExpandFatherItem("4",vectorElementBluegrass,"Bluegrass",vectorElementLabel));
        return data;
    }

   /**
     * 填充子组件数据
     *
     * @param name name
     * @return List
     */
    private List<ExpandChildItem> getChildData(String[] name) {
        ArrayList<ExpandChildItem> data = new ArrayList<>();
        for (int i = 0; i < name.length; i++) {
            data.add(new ExpandChildItem(name[i]));
        }
        return data;
    }

    /**
     * 子组件数据绑定到指定的父组件上
     *
     * @return Map
     */
    private Map<String, List<ExpandChildItem>> getChildMap() {
        Map<String, List<ExpandChildItem>> childMap = new HashMap<>();
        childMap.put("0",getChildData(ChildData.ROCK_CHILD));
        childMap.put("1",getChildData(ChildData.JAZZ_CHILD));
        childMap.put("2",getChildData(ChildData.CLASSIC_CHILD));
        childMap.put("3",getChildData(ChildData.SALSA_CHILD));
        childMap.put("4",getChildData(ChildData.BLUEGRASS_CHILD));
        return childMap;
    }

    public class ChildData {
        public static final String[] ROCK_CHILD = {"Queen","Styx","REO Speedwagon","Boston"};
        public static final String[] JAZZ_CHILD = {"Miles Davis","Ella Fitzgerald","Billie Holiday"};
        public static final String[] CLASSIC_CHILD = {"Ludwig van Beethoven","Johann Sebastian Bach",
            "Johannes Brahms","Giacomo Puccini"};
        public static final String[] SALSA_CHILD = {"Hector Lavoe","Celia Cruz","Willie Colon","Marc Anthony"};
        public static final String[] BLUEGRASS_CHILD = {"Bill Monroe","Earl Scruggs","Osborne Brothers","John Hartford"};
        private ChildData() {
    }
}

```
