本文介绍了一种在Android应用中使用Glide库高效加载和显示网络图片的方法。通过自定义适配器实现了图片的列表展示，并利用RecyclerView进行性能优化。此外，还提供了具体的代码示例，包括如何设置图片的占位符、裁剪方式及淡入效果。

参考 http://www.codeceo.com/article/android-glide-usage.html

public class GlideImgAdapter extends RecyclerView.Adapter<GlideImgAdapter.GlideHolder>{

    private List<String> imgList;
    private Context context;

    public GlideImgAdapter(Context context,List<String> imgList) {
        this.imgList = imgList;
        this.context = context;
    }

    @Override
    public int getItemCount() {
       return this.imgList.size();
    }

    @Override
    public GlideHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new GlideHolder(LayoutInflater.from(context).inflate(R.layout.item_layout,parent,false));
    }

    @Override
    public void onBindViewHolder(GlideHolder holder, int position) {

        Glide.with(context).load(this.imgList.get(position))
                .placeholder(R.drawable.defualt)
                .centerCrop()
                .crossFade()
                .into(holder.imageView);

    }

    class GlideHolder extends RecyclerView.ViewHolder{

        public ImageView imageView;

        public GlideHolder(View itemView) {
            super(itemView);
            imageView = (ImageView) itemView.findViewById(R.id.img);
        }
    }
}

//显示

List<String> imgList = Arrays.asList(ImageUtil.IMAGES);
        mRecyclerView = (RecyclerView) this.findViewById(R.id.recycleview);
        LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
        mRecyclerView.setLayoutManager(layoutManager);
        GlideImgAdapter imgAdapter = new GlideImgAdapter(this,imgList);
        mRecyclerView.setAdapter(imgAdapter);

public class ImageUtil {

    public static final String[] IMAGES = new String[] {
