使用LoopPagerAdapter的时候，会有部分网络图片加载不出来，不入有加载了5张网络图片，可能就会有三张网络图片加载不出来，然后重新刷新又会出来

如题

PointHintView其实可以抽象出一个基类，方便继承实现N多种指示器。如：

public abstract class ShapeHintView extends LinearLayout implements HintView {
    private Drawable focusDrawable, normalDrawable;

    protected abstract Drawable makeFocusDrawable();

    protected abstract Drawable makeNormalDrawable();

 @Override
    public void makeView(int length, int gravity) {
        ...
        normalDrawable = makeNormalDrawable();
        focusDrawable = makeFocusDrawable();
        ...
    }

public class CircleHintView extends ShapeHintView {
    @Override
    protected Drawable makeFocusDrawable() {
        GradientDrawable dot_focus = new GradientDrawable();
        dot_focus.setColor(Color.parseColor("#E3AC42"));
        dot_focus.setCornerRadius(Util.dip2px(getContext(), 4));
        dot_focus .setSize(Util.dip2px(getContext(), 8), Util.dip2px(getContext(), 8));
        return dot_focus ;
    }

    @Override
    protected Drawable makeNormalDrawable() {
        GradientDrawable dot_normal = new GradientDrawable();
        dot_normal.setColor(Color.WHITE);
        dot_normal.setAlpha(125);
        dot_normal.setCornerRadius(Util.dip2px(getContext(), 4));
        dot_normal.setSize(Util.dip2px(getContext(), 8), Util.dip2px(getContext(), 8));
        return dot_normal;
    }

public class IconHintView extends ShapeHintView {

    protected Drawable makeFocusDrawable() {
        return context.getDrawable(android.R.drawable.button_onoff_indicator_on);;
    }

    protected Drawable makeNormalDrawable() {
        return context.getDrawable(android.R.drawable.button_onoff_indicator_off);;
    }

}

两张图片的时候 是没问题的 有动画

远程库导入不了我的项目里面。。。

如图：
返回POSITION_UNCHANGED不是可以减少调用instantiateItem去创建ChildView；
而返回POSITION_NONE则要求每次notify的时候，（清理缓存）clear viewList，从新调用instantiateItem去创建一系列（默认3个）ChildView，加入到viewList；

请问：使用POSITION_NONE的原因，没有弄清楚真正的用意，很困惑，求解

在5.0以上运行没有问题，但是在4.4以下却是空白，什么都不显示。

是不是不兼容5.0以下版本？

以下是我的代码：

在RecyclerView Holder中嵌入RollPagerView

public class ViewBannerHolder extends RecyclerView.ViewHolder{

        @BindView(R.id.news_banner)
        RollPagerView mNewsBanner;

        ViewBannerHolder(View v, List<News> topNewses) {
            super(v);
            ButterKnife.bind(this, v);

            this.mNewsBanner.setHintView(new ColorPointHintView(v.getContext(), Color.YELLOW, Color.WHITE));
            this.mNewsBanner.setAdapter(new TopNewsLoopAdapter(mNewsBanner, topNewses));
        }
    }

在RecyclerView.Adapter的onCreateViewHolder()方法中构建ViewBannerHolder:

if(position == 0 && null != mTopNewses){
    View view = this.mLayoutInflater.inflate(R.layout.news_adapter_banner, parent, false);;
    return new ViewBannerHolder(view, mTopNewses);
}

RollViewPaper Adapter:

public class TopNewsLoopAdapter extends LoopPagerAdapter {

    private List<News> mTopNews;

    public TopNewsLoopAdapter(RollPagerView viewPager) {
        super(viewPager);
    }

    public TopNewsLoopAdapter(RollPagerView viewPager, List<News> topNews){
        super(viewPager);
        this.mTopNews = topNews;
    }

    @Override
    public View getView(ViewGroup container, int position) {
        View view = LayoutInflater.from(container.getContext()).inflate(R.layout.news_adapter_banner_view, container, false);

        final News news = this.mTopNews.get(position);
        ImageView imageView = (ImageView)view.findViewById(R.id.news_banner_image);
        ImageUtil.displayImage(container.getContext(), imageView, news.getImage());

        TextView textView = (TextView)view.findViewById(R.id.news_banner_title);
        textView.setText(news.getTitle());

        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(v.getContext(), NewsDetailActivity.class);
                intent.putExtra("newsId", news.getId());
                v.getContext().startActivities(new Intent[]{intent});
            }
        });
        return view;
    }

    @Override
    protected int getRealCount() {
        return null==this.mTopNews ? 0 : this.mTopNews.size();
    }
}

作者你好，很感谢分享你的项目，我在实际应用中发现，RollPagerView中startPlay()用到timer.schedule(new TimerTask() {}这里有个匿名TimerTask内部类会导致内存泄露

希望作者可以修改一下，小小建议，再次感谢

能往一个方向轮播么？比如往左都只往左无限轮播，现在是第一张左划不到最后一张，最后一张右滑不到第一张

而且不管传入什么大小图片,圆点大小都不变.

<com.jude.rollviewpager.RollPagerView
android:layout_width="match_parent"
android:layout_height="@dimen/base168dp"
android:id="@+id/tabhome_autovp"
app:rollviewpager_play_delay="3000"
app:rollviewpager_hint_paddingBottom="@dimen/base8dp"
></com.jude.rollviewpager.RollPagerView>

tabhomeAutovp.setHintView(new IconHintView(getActivity(), R.drawable.point_white, R.drawable.point_white80));
tabhomeAutovp.setAdapter(new LoopAdapter(tabhomeAutovp, vpPics));

用LoopPagerAdapter时，getCount值是Integer.MAX_VALUE，这样会很耗性能的呀

使用1.4.5版本
适配器:RollPagerAdapter
加载环境:网络加载图片 使用Fresco
页面中是RollPagerView下面放listView或者recycleView
启动页面时会出现IllegalStateException异常
所有数据改变位置都添加了Adapter.notifyDataSetChanged(); 依然报错

。。

有下拉刷新和viewpager的时候，左右华东bannar很难滑动

我在Activity的onCreate()中调用setAdapter()没有任何问题。但是，出于一种需求，我开启一个线程去获取新的图片，在图片获取结束后在runOnUiThread中调用setAdapter()更换成新的图片时，出现ANR，界面卡死，UI线程CPU满占用，十几秒后才恢复。即使我在getView()中返回new ImageView(container.getContext())，也是一样卡死，说明不是我在getView()中做耗时操作造成的这个ANR。望修复这个bug

==补充：broadcastreceiver的onReceive()事件中进行setAdapter()也不行

比如手指左滑 : 在第三页拖到第四页， 拖动到一半（或多或少都会） 然后取消滑动。
正常是回到第三页的。
但是有时会直接退回到第二页去。（换个方向也会）

在魅蓝上是好的
但是在三星note4上Error是OOM,应该显示图片的地方显示黑块

建议在只有一张图片的情况下，禁止viewpager的滑动

ScrollView包含RollViewPager不显示

在主要的 Moudle 中的 AndroidMenifest.xml 如果已有屬性

< application

< /application>
則在引用的 Library Moudle 中的 AndroidMenifest.xml 也設有相同的屬性設置
android:theme="@android:style/Theme.XXX
則會報出上述錯誤，將 Library Moudle 中的該屬性消除即可。

场景是数据源一开始是零，访问网络后拿到了数据然后通过notifyDataSetChanged更新，但是一直往前滑的话就滑不动了，只能往后滑

如何添加点击事件呢~ 我重写的instantiateItem 控制吗？

不好意思又来了。。我用了LoopPagerAdapter的notifydatasetchange方法，但是使用后似乎向左滑动会出现问题，在第一张图时会无法向左滑动。。。

轮播图循环时，要等很久才能加载出图片是什么原因呢，求解答
补充：是在请求网络之后再加载要等很久才能加载，尽管轮播图没有用到任何网络数据，setAdapter也执行完了，图片还是没有出来，用PagerView也有这种情况

与Glide图片加载框架结合使用时，加载进来的图片有时会比例失真，有时又是比例正常的。请解决比例失真的bug

代码：
LoopPagerAdapter loopPagerAdapter=new LoopPagerAdapter(rollPagerView) {
@OverRide
public View getView(ViewGroup container, int position) {
ImageView imageView = new ImageView(container.getContext());

            Glide
                    .with(MainFragment.this)
                    .load(xxxxxxxUrl)
                    .centerCrop()
                    //.placeholder(R.color.windowBackground)
                    //.diskCacheStrategy(DiskCacheStrategy.SOURCE)
                    .crossFade()
                    .into(imageView);


            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setLayoutParams(new                            ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
            return imageView;
        }

        @Override
        public int getRealCount() {
            return rollPicList==null?1:rollPicList.size();
        }

    };

    rollPagerView.setAdapter(loopPagerAdapter);
    rollPagerView.setPlayDelay(4000);
}

这个支持自定义的fragment显示吗？

照片由多变少的时候（大于一变为小于等于一） 底部indicator没有被初始化
需要把RollPagerView中的initHint改为public 然后再适配器的getview中作判断
if (_urls.size() < 2) {
_viewPager.setHintView(null);
} else {
_viewPager.initHint(
new ColorPointHintView(_viewPager.getContext(), Color.parseColor("#394482"),
Color.parseColor("#88ffffff")));
}
我这里大于1张才显示indicator。
大神可以考虑把它加到LoopPagerAdapter中

请问可以为轮播页添加文字随图片一起滚动播放吗

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

比如说，刚开始的广告有4页，刷新后只有1页时.只要上次的广告停留的不是第一页，刷新后不仅图片没有刷新，而且必崩。提示信息如下

可以看出at com.zhipu.salehelper.referee.widget.rollviewpager.RollPagerView$TimeTaskHandler.handleMessage(RollPagerView.java:133)这一行崩的。
刷新代码如下

bannerList.clear();
bannerList.addAll(list);
mLooperAdapter.notifyDataSetChanged();

如果只有两张图片的话，初始化默认会显示第二张图片，但指示器默认会显示的是第一个。也就是指示器和图片不匹配。只在初始化的时候有这个问题，轮播开始之后就正常了。

怎么用textHint？

轮播图怎么无限循环呢

滑动不好使，在右侧向左滑的时候很难滑动到下一页

如果使用LoopPagerAdapter，在配合上Picasso轮播网络图片时，如果网络图片稍大，会导致页面挂起，等待Picasso图片加载完毕后才会恢复，而使用staticPagerAdapter时没有这个问题。
