Android Glide not support StateListDrawable

[gjdyo...@126.com]

I try to use StateListDrawable R.drawable.image in Glide, but it always show the error R.drawable.default_image. However, if replace R.drawable.image with R.drawable.image_add_sel, it will show normally. I use it as below:

Glide.with(context)                                  
 .load(R.drawable.image)                                 
 .error(R.drawable.default_image)            
 .placeholder(R.drawable.default_image)       
 .diskCacheStrategy(DiskCacheStrategy.RESULT) 
 .into(imageView);

I find the root cause is :

in com.bumptech.glide.load.data.FileDescriptorLocalUriFetcher.java

    @Override

    protected ParcelFileDescriptor loadResource(Uri uri, ContentResolver contentResolver) throws FileNotFoundException {

        return contentResolver.openAssetFileDescriptor(uri, "r").getParcelFileDescriptor();

    }

It will throw "This file can not be opened as a file descriptor; it is probably compressed" exception, it not support StateListDrawable  resource.

I think it's common to use StateListDrawable in ImageView, so could this issue be fixed? Thanks.

Glide doesn't support Drawable types other than simple BitmapDrawables. If you're interested in adding support, I'd be willing to look at PR. In general there's not a lot of value to using Glide to load standard resources.

Even if it went past that exception https://github.com/bumptech/glide/issues/350 would prevent continuing forward.

Thanks for your prompt and kind reply. Now I find a workaround to fix this issue as below:

Glide.with(context)                                  

     .load(R.drawable.image)                                 

     .error(R.drawable.image)             

     .placeholder(R.drawable.image)       

     .diskCacheStrategy(DiskCacheStrategy.RESULT) 

     .into(imageView);

 

In addition, I think it's necessary to add XML drawable support in Glide.

We always use Glide in GridView or ListView to async loading images, but sometimes we want to

show xml drawable in GridView or ListView meanwhile. If we use ImageView.setImageDrawable(***) to load drawable, it will not show correctly for the views reusing in GridView and ListView. At this moment, we'd better use Glide to show drawable, too.

Thanks.

I guess you mean that when glide reuse a view, there is a chance that it will display what was loading there ?  
It is very easy to use the same view for both glide and classic view.setImageResource calls.

In this second case, you just have to call `Glide.clear(imageview);` in order to tell glide to release any resource and to stop any load associated  with that view. Then you can manipulate this view yourself.

Yeah, many thanks for your reply. That really resolves my issue. Thanks.
