Question

我收到此运行时错误

android.content.res.Resources$NotFoundException: Resource ID #0x0

我班上第38行：（Drawable res = context.getResources().getDrawable(imageResource);）

   @Override
   public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = context.getLayoutInflater();
        View view = inflater.inflate(R.layout.breed, null);
        Breed breed = breeds.get(position);
        String breedName = breed.getNameString(context);
        ((TextView) view.findViewById(R.id.breedNameText)).setText(breedName);
        String uri = "drawable/" + breedName.toLowerCase().replace(" ", "_");
        int imageResource = context.getResources().getIdentifier(uri, null, context.getPackageName());
        ImageView image = (ImageView) view.findViewById(R.id.breedImage);
        Drawable res = context.getResources().getDrawable(imageResource); // error occurs here
        image.setImageDrawable(res);
        return view;
   }

}

我需要更改它，但我还需要将其更改为将我的图片更改为适当的图片，因为我使用此图片为不同的组拖动不同的图片。谁能告诉我怎么做？

替换

String uri = "drawable/" + breedName.toLowerCase().replace(" ", "_");
int imageResource = context.getResources().getIdentifier(uri, null, context.getPackageName());

使用

int imageResource = context.getResources().getIdentifier(breedName.toLowerCase().replace(" ", "_"), "drawable", context.getPackageName());

注意：

1. getIdentifier returns 0 if no such resource was found. (0 is not a valid resource ID.)
2. Also check in your R.java whether there is a drawable with the given breedName.
