我有这个奇怪的问题,我的适配器没有调用任何方法..构造函数工作,它停在那里,如果我有一个断点,但从那里,没有.. onCreateViewHolder没有被调用,既没有onBindViewHolder,甚至没有getItemCount ..我尝试了我在网上找到的所有东西,但似乎没有任何工作,所以我不知道该怎么做.有什么建议？这是我的代码：

public class FragmentPackageDetails extends Fragment {

return v;
}

rvPackageDetails.setLayoutManager(new LinearLayoutManager(getActivity()));
database = new DatabaseHandler(getActivity());
selectedPackage = database.getPackage(trackerCode);
RecyclerView.Adapter adapter = new MyAdapter(selectedPackage.getRecords());
rvPackageDetails.setAdapter(adapter);
}
//other methods in class
}
MyAdapter
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
private ArrayList<TrackingRecordCheckedOut> mDataset;
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item,and
// you provide access to all the views for a data item in a view holder
public class ViewHolder extends RecyclerView.ViewHolder {
// each data item is just a string in this case
public TextView tvPackageDetailsRowDayOfWeek,tvPackageDetailsRowDayOfMonth,tvPackageDetailsRowNameOfMonth,tvPackageDetailsRowDetailsTitle,tvPackageDetailsRowDetailsDescription,tvPackageDetailsRowDetialsTime;

// Provide a suitable constructor (depends on the kind of dataset)
public MyAdapter(ArrayList<TrackingRecordCheckedOut> myDataset) {
mDataset = myDataset;
}
// Create new views (invoked by the layout manager)
@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {
// create a new view
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recyclerview_list_item,parent,false);
// set the view's size,margins,paddings and layout parameters
ViewHolder vh = new ViewHolder(v);
return vh;
}
// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(ViewHolder holder,int position) {
// - get element from your dataset at this position
// - replace the contents of the view with that element
TrackingRecordCheckedOut tr = mDataset.get(position);
holder.tvPackageDetailsRowDayOfWeek.setText(tr.getDayOfWeek());
holder.tvPackageDetailsRowDayOfMonth.setText(tr.getDayOfWeek());
holder.tvPackageDetailsRowNameOfMonth.setText(tr.getMonthOfYear());
holder.tvPackageDetailsRowDetailsTitle.setText(tr.getTitle());
holder.tvPackageDetailsRowDetailsDescription.setText(tr.getDetails());
holder.tvPackageDetailsRowDetialsTime.setText(tr.getTimeOfDay());
}
// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
return mDataset.size();
}
}

解决方法
@H_404_20@ 我看了你的代码不幸的是没有真正看到一个问题.可能有问题的一点是,在ViewHolder构造函数中,您调用super(v).您可能需要调用super((LinearLayout)v).但这可能没什么区别.祝好运！
