#### 安装教程
方式一：

1.在项目根目录下的build.gradle文件中，

 ```

allprojects {

    repositories {

        maven {

            url 'https://s01.oss.sonatype.org/content/repositories/releases/'

        }

    }

}

 ```

2.在entry模块的build.gradle文件中，

 ```

 dependencies {

    implementation('com.gitee.chinasoft_ohos:ExpandableLayout: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
####  使用方式
第一步：
```xml 
  <ScrollView
        ohos:id="$+id:scrollview"
        ohos:background_element="#ffffff"
        ohos:height="match_parent"
        ohos:width="match_parent">

        <DependentLayout
            ohos:orientation="horizontal"
            ohos:height="match_content"
            ohos:width="match_parent">
            <com.hos.expandblelib.ExpandableLayout
                ohos:id="$+id:el"
                ohos:width="match_parent"
                ohos:height="match_parent"/>
        </DependentLayout>
    </ScrollView>
```
第二步：设置数据
```
       sectionLinearLayout.addSection(getSection());
```
第三步：数据更新以及展开关闭的回调
```
   sectionLinearLayout.setRenderer(new ExpandableLayout.Renderer<FruitCategory, Fruit>() {
            @Override
            public void renderParent(Component view, FruitCategory model, boolean isExpanded, int parentPosition) {
                ((Text) view.findComponentById(ResourceTable.Id_tvParent)).setText(model.getName());
                Image image = (Image) view.findComponentById(ResourceTable.Id_arrow);
                image.setPixelMap(isExpanded ? ResourceTable.Graphic_arrow_down : ResourceTable.Graphic_arrow_up);
            }

            @Override
            public void renderChild(Component view, Fruit model, int parentPosition, int childPosition) {
                ((Text) view.findComponentById(ResourceTable.Id_tvChild)).setText(model.getName());
            }

        });
```
        sectionLinearLayout.setExpandListener((ExpandCollapseListener.ExpandListener<FruitCategory>) (parentIndex, parent, view) -> {
            Image image = (Image) view.findComponentById(ResourceTable.Id_arrow);
            image.setPixelMap(ResourceTable.Graphic_arrow_down);
        });
```
        sectionLinearLayout.setCollapseListener((ExpandCollapseListener.CollapseListener<FruitCategory>) (parentIndex, parent, view) -> {
            Image image = (Image) view.findComponentById(ResourceTable.Id_arrow);
            image.setPixelMap(ResourceTable.Graphic_arrow_up);
        });

```
