Question

我尝试使用这个库：

https://github.com/leocadiotine/WebCachedImageView/

我使用Emulator，API级别17，将WebCachedImageView添加到ListView抛出ListViewAdapter

public View getView(int pos, View child, ViewGroup parent) {
    Holder mHolder;
    LayoutInflater layoutInflater;
    if (child == null) {
        layoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        child = layoutInflater.inflate(R.layout.sent_listview_item, null);
        mHolder = new Holder();
        mHolder.txt_fileName    = (TextView) child.findViewById(R.id.txt_sentLV_fileName);
        mHolder.img_preview     = (WebCachedImageView) child.findViewById(R.id.wciv);
        child.setTag(mHolder);
    } else {
        mHolder = (Holder) child.getTag();
    }
    mHolder.txt_fileName.setText(fileName.get(pos));
    return child;
}

public class Holder {
    WebCachedImageView img_preview;
    TextView txt_fileName;
}

我收到了这个错误：

我想到这个错误：

mDiskCache = DiskLruCache.open(cacheDir, 1, 1, DISK_CACHE_SIZE); https://github.com/leocadiotine/WebCachedImageView/blob/master/code/src/io/leocad/webcachedimageview/CacheManager.java#L93

Plase帮帮我

我做到了。

由于问题是这个类的初始化：

Caused by: java.lang.NoClassDefFoundError: com.jakewharton.DiskLruCache

我删除了依赖DiskLruCache并在ClassPath中重新添加了。

这激发了我对这篇文章的启发： http://javarevisited.blogspot.ru/2011/06/noclassdeffounderror-exception-in.html
