    	maven { url 'https://jitpack.io' }
    }
}
```

}
```

Maven

* 添加JitPack
```xml

        <url>https://jitpack.io</url>
    </repository>
</repositories>
```

* 添加依赖
```xml
<dependency>
    <groupId>com.github.demoNo</groupId>
    <artifactId>AutoScrollViewPager</artifactId>
    <version>v1.0.2</version>

## 使用

* 在xml中定义

```xml
<com.github.demono.AutoScrollViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    app:stopWhenTouch="true"
    app:slideInterval="5000"
    app:slideDirection="right"
    app:slideDuration="5000"/>
```

* 创建Adapter继承InfinitePagerAdapter
```Java
public class MyAdapter extends InfinitePagerAdapter {

    private List<String> data;

    public MyAdapter(List<String> data) {
        this.data = data;
    }

    @Override
    public int getItemCount() {
        return data == null ? 0 : data.size();
    }

    @Override
    public View getItemView(int position, View convertView, ViewGroup container) {
        return your view;
    }
}
```

* 设置ViewPager Adapter
```Java
@Override
protected void onCreate(Bundle savedInstanceState) {
    AutoScrollViewPager mViewPager = (AutoScrollViewPager) findViewById(R.id.viewPager);
    MyAdapter mAdapter = new MyAdapter(data);
    mViewPager.setAdapter(mAdapter);
    // optional start auto scroll
    mViewPager.startAutoScroll();
}
```

## 更多设置

* `startAutoScroll()` 开启自动滚动.
* `stopAutoScroll()` 停止自动滚动.
* `setSlideInterval(int slideInterval)` 设置自动滚动的间隔时间，默认5000毫秒.
* `setDirection(int direction)` 设置自动滚动的方向 `DIRECTION_RIGHT` 或者 `DIRECTION_LEFT`，默认向右.
* `setStopWhenTouch(boolean stopWhenTouch)` 触摸时是否停止自动滚动，默认为true.
* `setCycle(boolean cycle)` 当自动滚动到最后一个item时是否自动回到第一个item，只对继承自 `PagerAdapter`的 `Adapter`有效，默认false.
