如何集成

修改entry的bulid.gradle,代码如下

 implementation 'io.openharmony.tpc.thirdlib:SlidingDrawer:1.0.2'

需要在xml布局添加如下代码片段

</hollowsoft.slidingdrawer.SlidingDrawer>

java 代码需要添加如下代码

SlidingDrawer drawer = new SlidingDrawer(this);
drawer.setOrientation(Component.VERTICAL);//todo 设置方向
drawer.setHandle(new Component(this));//todo 这个必须设置

抽屉布局打开
```
drawer.animateOpen();
```
抽屉布局关闭
```
drawer.animateClose();
```

代码运行

绘画xml布局

在xml布局中绘画一个导航布局和抽屉列表布局，具体参考xml布局注释，代码如下

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout ohos:id="$+id:main"
                xmlns:ohos="http://schemas.huawei.com/res/ohos"
                ohos:height="match_parent"
                ohos:width="match_parent"
                ohos:orientation="vertical">
<!--    头部当行栏-->
    <DirectionalLayout
        ohos:background_element="blue"
        ohos:height="80vp"
        ohos:width="match_parent"
        ohos:orientation="horizontal">
<!--        菜单栏-->
        <Text
            ohos:left_margin="10vp"
            ohos:id="$+id:hos"
               ohos:width="80vp"
               ohos:height="match_parent"
            ohos:text_color="#ed6262"
            ohos:text_size="20vp"
               ohos:text="菜单"/>
<!--标题栏-->
        <Text
            ohos:width="0vp"
            ohos:weight="1"
            ohos:height="match_parent"
            ohos:text_alignment="center"
            ohos:text_size="20vp"
            ohos:text_color="#ffffff"
            ohos:text="界面标题"/>
        <Text
            ohos:right_margin="10vp"
            ohos:width="80vp"
            ohos:height="match_parent"
            ohos:text_color="#ed6262"
            ohos:text_size="20vp"/>
    </DirectionalLayout>
<!--抽屉布局-->
    <hollowsoft.slidingdrawer.SlidingDrawer
        ohos:id="$+id:slide"
        ohos:background_element="#20000000"
        xmlns:ohos="http://schemas.huawei.com/res/ohos"
        ohos:height="500vp"
        ohos:width="match_parent"
        ohos:orientation="horizontal">
        <DirectionalLayout
            ohos:width="500vp"
            ohos:alignment="top"
            ohos:height="match_parent"
            ohos:orientation="vertical">
<!--            菜单一-->
        <Text
            ohos:id="$+id:text_menu_one"
            ohos:height="80vp"
            ohos:background_element="#ffffff"
            ohos:width="match_parent"
            ohos:text_size="20vp"
            ohos:text="菜单一"/>
<!--            菜单二-->
            <Text
                ohos:id="$+id:text_menu_two"
                ohos:top_margin="1vp"
                ohos:height="80vp"
                ohos:background_element="#ffffff"
                ohos:width="match_parent"
                ohos:text_size="20vp"
                ohos:text="菜单二"/>
<!--            菜单三-->
            <Text
                ohos:id="$+id:text_menu_there"
                ohos:top_margin="1vp"
                ohos:height="80vp"
                ohos:background_element="#ffffff"
                ohos:width="match_parent"
                ohos:text_size="20vp"
                ohos:text="菜单三"/>

        </DirectionalLayout>
    </hollowsoft.slidingdrawer.SlidingDrawer>
</DirectionalLayout>

实现java 代码

给“菜单”实现点击事件，控制抽屉布局的打开，然后在实现菜单列表的点击事件，具体代码如下
