更改

  View view = LayoutInflater.from(mContext).inflate(R.layout.layout_sort_search,null);

另一个视图也是如此。它应该会起作用

试试这个

 @Override
 public int getViewTypeCount() {
 // return the total number of view types. this value should never change at      runtime
 return 2;
}

@Override
public int getItemViewType(int position) {
// return a value between 0 and (getViewTypeCount - 1)
return position % 2;
}
  View view = LayoutInflater.from(mContext).inflate(R.layout.layout_sort_search,null);
  View view = LayoutInflater.from(mContext).inflate(R.layout.layout_sort_search,parent, false);
 @Override
 public int getViewTypeCount() {
 // return the total number of view types. this value should never change at      runtime
 return 2;
}

@Override
public int getItemViewType(int position) {
// return a value between 0 and (getViewTypeCount - 1)
return position % 2;
}
