Android GridView android.view.InflateException：二进制 XML 异常

Question

再见，我创建了一个 GridView 画廊，网格视图项是 ImageView 和 TextView 的复合体，所以我使用了 inflate 文件 grid_folder_item.xml。 应用程序启动时抛出异常：

以下文件是应用程序的网格适配器：

package it.bwpp.adapter;

public class ImageGridAdapter extends BaseAdapter {

      private List<PictureFolder> picturesFolders;

      public ImageGridAdapter(Context c, List<PictureFolder> folders) {
            mContext = c;
            this.picturesFolders = folders;
        }

      public int getCount() {

        }

        public long getItemId(int position) {

        }

        // create a new ImageView for each item referenced by the Adapter
        public View getView(int position, View convertView, ViewGroup parent) {
            View itemView = convertView;
            if (convertView == null){
                LayoutInflater li = ((Activity)mContext).getLayoutInflater();
                itemView = li.inflate(R.layout.grid_folder_item, null);

                ImageView imageView = (ImageView)itemView.findViewById(R.id.grid_folder_image);
                imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
                imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
                imageView.setPadding(8, 8, 8, 8);
                imageView.setImageBitmap(picturesFolders.get(position).getPreviewImage());

                TextView tv = (TextView) itemView.findViewById(R.id.grid_folder_name);

            }
            return itemView;
        }
}

请帮助我。 再见。

你有Textview，应该是TextView。
