#### 安装教程

1.在项目根目录下的build.gradle文件中,
 ```gradle
allprojects {
    repositories {
        maven {
            url 'https://s01.oss.sonatype.org/content/repositories/snapshots/'
        }
    }
}
 ```
2.在entry模块的build.gradle文件中,
```xml
 dependencies {
    implementation('com.gitee.chinasoft_ohos:FlipViewPager.Draco:0.0.3-SNAPSHOT')
    
 }
```
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

xml布局引用 FlipViewPager

```xml
<?xml version="1.0" encoding="utf-8"?>
<com.yalantis.flipviewpager.FlipViewPager
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:id="$+id:flip_list"
    ohos:height="200vp"
    ohos:width="match_parent"/>
```
 用自己的Provider继承 BaseFlipAdapter,实现抽象的方法

```java
public class FriendProvider extends BaseItemProvider {
    // ... other code
    @Override
    public Component getComponent(int position, Component component, ComponentContainer componentContainer) {
        Component cpt = component;
        if (cpt == null) {
            cpt = LayoutScatter.getInstance(context).parse(ResourceTable.Layout_friend_item, null, false);
        }
        final int defaultPage = 2;
        FlipViewPager flipViewPager = (FlipViewPager) cpt.findComponentById(ResourceTable.Id_flip_list);
        //设置flipView的位置
        flipViewPager.setIndex(position);
        //设置touch监听
        flipViewPager.setLayoutTouchListener(this.layoutTouchListener);
        //设置页面时阴影效果
        flipViewPager.setFoldShading(new SimpleFlipShading());
        //设置provider
        flipViewPager.setProvider(new FlipViewPager.FlipProvider(flipItemArray.get(position)));
        //设置默认页
        flipViewPager.setCurrentPage(defaultPage);
        return cpt;
    }
}
```
 实现LayoutTouchListener监听
```java
public class MainAbilitySlice extends AbilitySlice implements LayoutTouchListener {
    // other code
    @Override
    public void requestDisallowInterceptTouchEvent(boolean isEnable) {
        //父布局是否响应事件,用来处理滑动冲突
        friendListContainer.setEnabled(isEnable);
    }

    @Override
    public void clickedItem(int position, int page, int direction) {
        // 点击friend头像时,显示nickname
        if (page == num2) {
            new ToastDialog(this)
                    .setOffset(0,offsetY)
                    .setText(Utils.friends.get(position * num2 + direction).getNickname())
                    .show();
        }
    }
}

```
 设置你的Provider ```ListContainer```

```Java
public class MainAbilitySlice extends AbilitySlice implements LayoutTouchListener {
    @Override
    protected void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_main);
        friendListContainer = (ListContainer) findComponentById(ResourceTable.Id_friendList);
        flipItemArray = new ArrayList<>();
        for (int i = 0; i < Utils.friends.size(); i += num2) {
            flipItemArray.add(FlipItemUtil.getFlipItems(i, i + 1, getContext()));
        }
        FriendProvider listProvider = new FriendProvider(flipItemArray, this);
        // 设置监听
        listProvider.setLayoutTouchListener(this);
        // 设置内容提供者
        friendListContainer.setItemProvider(listProvider);
        friendListContainer.setLongClickable(false);
    }
}

```
