使用方法：
---------

***1.导入library源码***

***2.调用AutoScrollPageView和设置参数***
  ```xml
<com.ihongqiqu.view.lib.AutoScrollViewPager
        android:id="@+id/view_pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
```
```java
@Override
public void onCreate(Bundle savedInstanceState) {
    // TODO setContentView and so on
    
    AutoScrollViewPager viewPager = (AutoScrollViewPager) findViewById(R.id.view_pager);
    AutoScrollViewPagerAdapter pagerAdapter = new AutoScrollViewPagerAdapter(MainActivity.this) {
        @Override
        public List<View> buildViews() {
            return addView();
        }
    };
    viewPager.setAdapter(pagerAdapter);
    viewPager.start();
        
    // TODO others
}
```
```java
private List<View> addView() {
    List<View> list = new ArrayList<>();
    for (int i = 0; i < ids.length; i++) {
        ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        ImageView view = new ImageView(this);
        view.setLayoutParams(params);
        view.setScaleType(ImageView.ScaleType.CENTER_CROP);
        view.setImageResource(ids[i]);
        view.setTag(i);
        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "position : " + v.getTag(), Toast.LENGTH_SHORT).show();
            }
        });
        list.add(view);
    }
    return list;
}
```
```java
@Override
protected void onPause() {
    super.onPause();
    viewPager.onPause();
}

@Override
protected void onResume() {
    super.onResume();
    viewPager.onResume();
}
```
 
***3.设置指示器（重要）***

```java
// 设置AutoScrollViewPager时添加监听
viewPager.setOnPageChangeListener(new MyOnPageChangeListener());
```

```java
public class MyOnPageChangeListener implements OnPageChangeListener {

@Override
        public void onPageSelected(int position) {
            // 重要：当前真正的位置需要转化 下面pos变量就是真实的位置，可以直接使用pos，不能使用position
            int pos = position % pagerAdapter.getRealPageCount();
            // TODO 根据当前位置pos来进行相应的操作
            
        }

@Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        }

@Override
        public void onPageScrollStateChanged(int arg0) {
        }
    }
```
