【Java UI】HarmonyOS 如何集成SlidingDrawer组件

 参考资料

SlidingDrawer

api讲解

• 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

  <DirectionalLayout ohos:id="$+id:main"
                  xmlns:ohos="http://schemas.huawei.com/res/ohos"
                  ohos:height="match_parent"
                  ohos:width="match_parent"
                  ohos:orientation="vertical">
      <DirectionalLayout
          ohos:background_element="blue"
          ohos:height="80vp"
          ohos:width="match_parent"
          ohos:orientation="horizontal">
          <Text
              ohos:left_margin="10vp"
              ohos:id="$+id:hos"
                 ohos:width="80vp"
                 ohos:height="match_parent"
              ohos:text_color="#ed6262"
              ohos:text_size="20vp"
                 ohos:text="菜单"/>
          <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>

              ohos:alignment="top"
              ohos:height="match_parent"
              ohos:orientation="vertical">
          <Text

• 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
