使用bmob的菜鸟，写了一个利用bmob把图文数据加载到listview的代码，图片文件是用的bmobfile，我是通过获取它的URL然后进行网络图片下载来加载图片的，但是运行出错了，求解决啊
adapter的代码：
public class ClassListAdapter extends BaseAdapter {
private Context mContext;
private LayoutInflater mInflater = null;// LayoutInflater作用是将layout的xml布局文件实例化为View类对象
private ArrayList mClassList = null; // 所选分类下的所有列表
public ClassListAdapter(Context context, ArrayList classList) {
setmContext(context);
mClassList = classList;
mInflater = LayoutInflater.from(context);
}
@Override
public int getCount() {
return mClassList.size();
}
@Override
public Object getItem(int position) {
return mClassList.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
public void refresh(ArrayList list) {
mClassList = list;
notifyDataSetChanged();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ClassHolder classHodler;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_class_item, null);
classHodler = new ClassHolder();
classHodler.tvClassName = (TextView) convertView
.findViewById(R.id.tv_cn);
classHodler.tvDate = (TextView) convertView
.findViewById(R.id.tv_date);
classHodler.ivClassPic = (ImageView) convertView
.findViewById(R.id.class_pic);
convertView.setTag(classHodler);
} else {
classHodler = (ClassHolder) convertView.getTag();
}
classHodler.tvClassName.setText(mClassList.get(position).getCname());
classHodler.tvDate.setText(mClassList.get(position).getDate());
String url = mClassList.get(position).getCpic().getFileUrl();
classHodler.ivClassPic.setTag(url);
new ImageLoader().showImageByThread(classHodler.ivClassPic, url);
return convertView;
}
public Context getmContext() {
return mContext;
}
public void setmContext(Context mContext) {
this.mContext = mContext;
}
}
listactivity的代码：
public class ClassActivity extends Activity implements OnItemClickListener {
private static final String TAG = "ClassActivity";
private ListView classListView;
private ArrayList classList = new ArrayList();
private ClassListAdapter mClassListAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_class_all);
initView();
initEvent();
}
private void initEvent() {
// TODO Auto-generated method stub
mClassListAdapter = new ClassListAdapter(this, classList);
classListView.setAdapter(mClassListAdapter);
classListView.setOnItemClickListener(this);
getClassData();
}
private void initView() {
// TODO Auto-generated method stub
classListView = (ListView) findViewById(R.id.lv_class_all);
}
private void getClassData() {
// TODO Auto-generated method stub
BmobQuery query = new BmobQuery();
query.order("-updatedAt");
query.findObjects(this, new FindListener() {
@Override
public void onSuccess(final List object) {
classList = (ArrayList) object;
mClassListAdapter.refresh((ArrayList) classList);
mClassListAdapter.notifyDataSetChanged();
}
@Override
public void onError(String arg0) {
toast("获取数据失败了");
}
});
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Intent toClassDetail = new Intent(ClassActivity.this,
ClassDetailActivity.class);
toClassDetail.putExtra("ClassName", classList.get(position).getCname());
toClassDetail.putExtra("ClassTeacherObjectId", classList.get(position)
.getTobjectid());
toClassDetail.putExtra("ClassDate", classList.get(position).getDate());
toClassDetail.putExtra("ClassTime", classList.get(position).getTime());
toClassDetail.putExtra("ClassInfo", classList.get(position).getCinfo());
toClassDetail.putExtra("ClassPic", classList.get(position).getCpic()
.getFileUrl());
startActivity(toClassDetail);
}
public void toast(String toast) {
Toast.makeText(this, toast, Toast.LENGTH_SHORT);
}
}
这是运行时报的错
