# SlideAndDragListView
这是一个自定义ListContaner控件，可以左右滑动菜单，上下拖拽改变item位置。
## 概述
* 支持左右滑动显示菜单
* 支持长按或触摸上下拖拽改变item位置
* 左右滑动菜单以及上下拖拽效果没有原组件体验好
## 演示
## 集成
```
方式一：
通过library生成har包，添加har包到libs文件夹内
在entry的gradle内添加如下代码
implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
方式二：
allprojects{
repositories{
mavenCentral()
}
}
implementation 'io.openharmony.tpc.thirdlib:SlideAndDragListView:1.0.0'
```
## entry运行要求
通过DevEco studio,并下载SDK
将项目中的build.gradle文件中dependencies→classpath版本改为对应的版本（即你的IDE新建项目中所用的版本）
### 示例
```xml
```
```java
/**
* 左右滑动菜单
*/
