android - InvocationTargetException 在适配器类中膨胀视图
问题描述
我正在尝试扩充自定义 recyclerview，但问题是每次我尝试在 onCreateViewHolder() 中扩充 xml 文件时，它都会生成 InvocationTargetException 异常。我还应用了一些已经可用的解决方案，但问题仍然存在。我没有得到我缺乏的地方。
public class CurrentListAdapter extends RecyclerView.Adapter<CurrentListAdapter.CurrentViewHolder> {
private List<Prescription> mLst;
private Context mContext;
private String[] list;
public CurrentListAdapter(List<Prescription> mLst, Context mContext) {
this.mLst = mLst;
this.mContext = mContext;
}
@NonNull
@Override
public CurrentViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = layoutInflater.inflate(R.layout.row_current_list_item, parent, false);
list = v.getResources().getStringArray(R.array.cStatus);
return new CurrentViewHolder(v);
}
@Override
public void onBindViewHolder(@NonNull CurrentViewHolder h, int position) {
Prescription p = mLst.get(position);
h.prescriptionId.setText(p.getPresId());
h.patientName.setText(p.getPatientName());
h.labTest.setText(p.getLabTest());
}
@Override
public int getItemCount() {
return mLst.size();
}
public class CurrentViewHolder extends RecyclerView.ViewHolder implements AdapterView.OnItemSelectedListener {
TextView prescriptionId, patientName, labTest, labComment;
Spinner status;
ArrayAdapter<String> adapter;
public CurrentViewHolder(@NonNull View v) {
super(v);
prescriptionId = v.findViewById(R.id.presId);
patientName = v.findViewById(R.id.patientName);
labTest = v.findViewById(R.id.labTest);
labComment = v.findViewById(R.id.comment);
status = v.findViewById(R.id.status);
final List<String> statusList = new ArrayList<>(Arrays.asList(list));
adapter = new ArrayAdapter<String>(itemView.getContext(), R.layout.spinner_item,statusList){
@Override
public boolean isEnabled(int position) {
if (position == 0)
{
return false;
}
else{
return true;
}
}
@Override
public View getDropDownView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
View view = super.getDropDownView(position, convertView, parent);
TextView tv = (TextView) view;
if(position == 0){
// Set the hint text color gray
tv.setTextColor(Color.GRAY);
}
else {
tv.setTextColor(Color.BLACK);
}
return view;
}
};
adapter.setDropDownViewResource(R.layout.spinner_item);
status.setAdapter(adapter);
status.setOnItemSelectedListener(this);
}
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
}
}
