再见，我已经创建了一个 GridView 库，网格视图项是 ImageView 和 TextView 的组合，所以我使用了膨胀文件 grid_folder_item.xml。应用程序启动时抛出的异常：

以下文件是应用程序的网格适配器：

package it.bwpp.adapter;

import it.bwpp.activity.R;
import it.bwpp.filemgr.PictureFolder;

import java.util.List;

import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.TextView;

public class ImageGridAdapter extends BaseAdapter {
      private Context mContext;
      private List<PictureFolder> picturesFolders;

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

      public int getCount() {
          return picturesFolders.size();
       }

        public Object getItem(int position) {
            return picturesFolders.get(position);
        }

        public long getItemId(int position) {
            return picturesFolders.get(position).getPath().hashCode();
        }

        // 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);
                tv.setText(picturesFolders.get(position).getName());
            } else {
                itemView = convertView;
            }
            return itemView;
        }
}

请帮帮我。再见。
