compile 'com.youth.banner:banner:+'

compile "com.github.bumptech.glide:glide:3.7.0"

<?xml version="1.0" encoding="utf-8"?>
<com.youth.banner.Banner xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/banner"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

public class GlideImageLoader extends ImageLoader {
    @Override
    public void displayImage(Context context, Object path, ImageView imageView) {
        //具体方法内容自己去选择，次方法是为了减少banner过多的依赖第三方包，所以将这个权限开放给使用者去选择
        Glide.with(context.getApplicationContext())
                .load(path)
                .crossFade()
                .into(imageView);

    }


}

final View header = LayoutInflater.from(getActivity()).inflate(R.layout.header, (ViewGroup) getActivity().findViewById(android.R.id.content), false);
mLRecyclerViewAdapter.addHeaderView(header);

banner = (Banner) header.findViewById(R.id.banner);

//更新图片数据

     banner.startAutoPlay();
    }

//界面不显示

@Override

}

1.添加布局fragment_hall_head.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/transparent"
    android:orientation="vertical">
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="300px">

        <android.support.v4.view.ViewPager
            android:id="@+id/viewPager"
            android:layout_width="match_parent"
            android:layout_height="300px" />

        <LinearLayout
            android:id="@+id/ll_points"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|center_horizontal"
            android:layout_marginBottom="11dp"
            android:orientation="horizontal" />

    </FrameLayout>
</LinearLayout>

2.添加资源文件

shape_xiao_yuan_quan_selected.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <size
        android:width="8dp"
        android:height="8dp" />
    <stroke
        android:width="1px"
        android:color="@color/colorAccent" />
    <solid android:color="@color/colorAccent" />
</shape>

shape_xiao_yuan_quan_nomal.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <size
        android:width="8dp"
        android:height="8dp" />
    <stroke
        android:width="1px"
        android:color="@color/white" />
    <solid android:color="@color/white" />
</shape>

3.代码：

初始化数据：
View bannerHead;
private LinearLayout llPoints; //图片里面的小圆点
private ViewPager viewPager;  //图片轮播
List<String> imgesUrl;

初始化图片：

bannerHead = View.inflate(mContext, R.layout.fragment_hall_head, null);
viewPager = (ViewPager) bannerHead.findViewById(R.id.viewPager);
llPoints = (LinearLayout) bannerHead.findViewById(R.id.ll_points);
imgesUrl = new ArrayList<>();
imgesUrl.add("http://img3.fengniao.com/forum/attachpics/913/114/36502745.jpg");
imgesUrl.add("http://imageprocess.yitos.net/images/public/20160910/99381473502384338.jpg");
imgesUrl.add("http://imageprocess.yitos.net/images/public/20160910/77991473496077677.jpg");
imgesUrl.add("http://imageprocess.yitos.net/images/public/20160906/1291473163104906.jpg");
dealLunBo();

初始化進行圖片的處理：

/**
 * 处理轮播图
 */

private void dealLunBo() {
    MyPagerAdapter myPagerAdapter = new MyPagerAdapter();
    viewPager.setAdapter(myPagerAdapter);
    viewPager.setCurrentItem(imgesUrl.size() * 10000);
    startRool();
    //初始化ViewPager轮播小圆圈
    llPoints.removeAllViews();
    for (int i = 0; i < imgesUrl.size(); i++) {
        ImageView point = new ImageView(getActivity());
        if (i == 0) {
            point.setImageResource(R.drawable.shape_xiao_yuan_quan_selected);
        } else {
            point.setImageResource(R.drawable.shape_xiao_yuan_quan_nomal);
        }
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        if (i > 0) {
            params.leftMargin = UiUtils.dp2px(getContext(), 8);
        }
        llPoints.addView(point, params);
    }
    //ViewPager的轮播效果(小圆圈改变)
    viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {
            position = position % imgesUrl.size();
            for (int i = 0; i < llPoints.getChildCount(); i++) {
