Android - Glide的使用

Glide setTag崩溃问题

java.lang.IllegalArgumentException: You must not call setTag() on a view Glide is targeting 

- 原因: 

and an Adapter which is using the usual ViewHolder pattern, i.e. inflating the view from resource (above) and setTag(vh);, now Glide wants to do the same when loading the image. 

- 解决方案: 

There could easily be a way to prevent conflicts, by allowing the ViewTarget users to set an ID to use with setTag(int, Object), even if it’s just a static method on ViewTarget (default beingView.NO_ID -> setTag(Object)).

问题代码：

@Override
public
View getView(final
int
position, View view, ViewGroup container) {

 final
ViewHolder holder;

 if
(view == null)
{ holder = new
ViewHolder();

view = holder.imageView =
new
ImageView(context);

holder.imageView .setLayoutParams(new
ViewGroup.LayoutParams(-1,
-1));

holder.imageView.setScaleType(ImageView.ScaleType.FIT_XY);

view.setTag(holder);

}
else
{ holder = (ViewHolder) view.getTag();

}

Glide.with(context)
.load((String) this.imageIdList.get(getPosition(position)))
.centerCrop()
.placeholder(R.drawable.meinv)
.error(R.drawable.meinv)
.into(holder.imageView);

我这里没有使用R.资源。而是new了一个ImageView，所以它报错，大意是需要一个id。

后来我改成了这样：

@Override
public View getView(final int position, View view, ViewGroup container) {
final ViewHolder holder;
if (view == null) {
view = LayoutInflater.from(context).inflate(R.layout.imageitem, null);
holder = new ViewHolder();
holder.imageView = (ImageView) view.findViewById(R.id.img_player);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}

Glide.with(context)
.load((String) this.imageIdList.get(getPosition(position)))
.centerCrop()
.placeholder(R.drawable.meinv)
.error(R.drawable.meinv)
.into(holder.imageView);

就可以了
