图片加载库Glide——解决图片错乱+无法设置tag

今天在写一个图片加载类ImageLoader,在使用的时候想用Glide替代我写的ImageLoader,然后问题就出来了！！！

第一个问题：在使用自己写的ImageLoader的时候，为了防止item复用导致的图片错乱，设置了Tag 如下代码

        @Override        public View getView(int position, View convertView, ViewGroup parent) {            ViewHolder holder = null;            if (convertView == null) {                convertView = mInflater.inflate(R.layout.image_list_item,parent, false);                holder = new ViewHolder();                holder.imageView = (ImageView) convertView.findViewById(R.id.image);                convertView.setTag(holder);            } else {                holder = (ViewHolder) convertView.getTag();            }            ImageView imageView = holder.imageView;            final String tag = (String)imageView.getTag();            final String uri = getItem(position);            if (!uri.equals(tag)) {                imageView.setImageDrawable(mDefaultBitmapDrawable);            }            if (mIsGridViewIdle && mCanGetBitmapFromNetWork) {                imageView.setTag(uri);                mImageLoader.bindBitmap(uri, imageView, mImageWidth, mImageWidth);            }            return convertView;        }

使用setTag（object），这里使用了每个图片的url地址来作为Tag来防止图片错乱
当使用Glide来替换ImageLoader,代码如下：

          public View getView(int position, View convertView, ViewGroup parent) {            ViewHolder holder = null;            if (convertView == null) {                convertView = mInflater.inflate(R.layout.item_gridview, parent, false);                holder = new ViewHolder();                holder.imageView = (ImageView) convertView.findViewById(R.id.image);                convertView.setTag(holder);            } else {                holder = (ViewHolder) convertView.getTag();            }            ImageView imageView = holder.imageView;            final String tag = (String) imageView.getTag();            final String uri = getItem(position);            if (!uri.equals(tag)) {                imageView.setImageDrawable(mDefaultBitmapDrawable);            }            if (mIsGridViewIdle && mCanGetBitmapFromNetWork) {                imageView.setTag(uri);                Glide.with(getApplicationContext()).load(uri).placeholder(R.drawable.image_default).crossFade().into(imageView);                //mImageLoader.bindBitmap(uri, imageView, mImageWidth, mImageWidth);            }            return convertView;        }

运行结果报错：java.lang.IllegalArgumentException: You must not call setTag() on a view Glide is targeting
然后将imageView设置Tag的代码删除，程序正常运行 。
但这个时候哟与出现一个问题，那就是图片错乱了。

第二个问题：删除ImageView的Tag的时候 图片错乱

解决问题的方法：使用setTag(int,object)方法设置tag 这样就解决了上面两个问题

        public View getView(int position, View convertView, ViewGroup parent) {            ViewHolder holder = null;            if (convertView == null) {                convertView = mInflater.inflate(R.layout.item_gridview, parent, false);                holder = new ViewHolder();                holder.imageView = (ImageView) convertView.findViewById(R.id.image);                convertView.setTag(holder);            } else {                holder = (ViewHolder) convertView.getTag();            }            ImageView imageView = holder.imageView;            final String tag = (String) imageView.getTag(R.id.imageloader_uri);            final String uri = getItem(position);            if (!uri.equals(tag)) {                imageView.setImageDrawable(mDefaultBitmapDrawable);            }            if (mIsGridViewIdle && mCanGetBitmapFromNetWork) {                imageView.setTag(R.id.imageloader_uri,uri);                Glide.with(getApplicationContext()).load(uri).placeholder(R.drawable.image_default).crossFade().into(imageView);                //mImageLoader.bindBitmap(uri, imageView, mImageWidth, mImageWidth);            }            return convertView;        }

这里的R.id.imageloader_uri是values下新建的ids.xml:

<?xml version="1.0" encoding="utf-8"?><resources>    <item name="imageloader_uri" type="id"/></resources>
