public abstract class CommonAdapter<T> extends BaseAdapter
{
 protected LayoutInflater mInflater;
 protected Context mContext;
 protected List<T> mDatas;
 protected final int mItemLayoutId;

 public CommonAdapter(Context context, List<T> mDatas, int itemLayoutId)
 {
  this.mContext = context;
  this.mInflater = LayoutInflater.from(mContext);
  this.mDatas = mDatas;
  this.mItemLayoutId = itemLayoutId;
 }

 @Override
 public int getCount()
 {
  return mDatas.size();
 }

 @Override
 public T getItem(int position)
 {
  return mDatas.get(position);
 }

 @Override
 public long getItemId(int position)
 {
  return position;
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent)
 {
  final ViewHolder viewHolder = getViewHolder(position, convertView,parent);
  convert(viewHolder, getItem(position));
  return viewHolder.getConvertView();

 }

 public abstract void convert(ViewHolder helper, T item);

 private ViewHolder getViewHolder(int position, View convertView,
   ViewGroup parent)
 {
  return ViewHolder.get(mContext, convertView, parent, mItemLayoutId,
    position);
 }

}
