我尝试通过捕获的相机和图库按钮监听器在网格视图中显示图像。之后，从存储它们的SD卡中删除选定的多个图像，并使用复选框从网格视图中删除。但是当我从相机或图库中捕获图像时，网格视图中没有显示图像。有人帮我解决了这个问题。谢谢提前。
这是我的活动代码
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

item.setBitmap(largeIcon);
imgItemArray.add(item);
//gridAdapter = new GridView_Adapter(this, R.layout.add_post_grid_item_layout, picsName);

@Override

if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.add_post_grid_item_layout, null);
holder.image = (ImageView) convertView.findViewById(R.id.image);
holder.checkbox = (CheckBox) convertView.findViewById(R.id.itemCheckBox);
convertView.setTag(holder);
} else {

}
Bitmap myBitmap = BitmapFactory.decodeFile(fileName.get(position));
Log.e("myBitmap ", " = " + myBitmap);
holder.image.setImageBitmap(myBitmap);
final int pos = position;
holder.checkbox.setOnClickListener(new View.OnClickListener() {

return convertView;

class ViewHolder

FileNotFoundException就在那里。检查一下它是否保存文件或在您的位置。 或更新全班。
