【问题描述】：
我试图在单击时更改我的文本视图（状态）之一，但它只是删除当前文本并显示我的原始文本的文本。 文本视图当前显示“未采用”或“待定”，具体取决于从我的数据库中检索到的数据。
我的弹出对话框片段代码在回收视图中显示卡片项目。
public class FragmentLocationPopup extends DialogFragment {
View mView;
TextView tvSelectedBranch;
RecyclerView mScheduleList;
ScheduleAdapter mAdapter;
RecyclerView.LayoutManager mLayoutManager;
String TAG = "DialogFragment";
ArrayList<Schedule> scheduleList;
VariablesHolder variablesHolder;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.fragment_location_popup, container, false);
createScheduleList();
buildRecyclerView();
return mView;
}
public void createScheduleList(){
scheduleList = new ArrayList<>();
tvSelectedBranch = mView.findViewById(R.id.tvSelectedBranch);
variablesHolder = (VariablesHolder) getActivity().getApplicationContext();
String selectedBranch = variablesHolder.getSelectedBranch();
tvSelectedBranch.setText(selectedBranch);
Log.d(TAG, "Selected branch = "+selectedBranch);
Call<List<Schedule>> call = RetrofitClient.getInstance().getApiDate().getSchedule();
call.enqueue(new Callback<List<Schedule>>() {
@Override
public void onResponse(Call<List<Schedule>> call, Response<List<Schedule>> response) {
List<Schedule> schedules = response.body();
for (Schedule schedule : schedules) {
if(schedule.getBranchID().equals(variablesHolder.getBranchID())) {
scheduleList.add(new Schedule(schedule.getWorkScheduleFromDateTime(), schedule.getWorkScheduleToDateTime(),schedule.getWorkScheduleStatus()));
Log.d(TAG, "onResponse: " + schedule.getWorkScheduleFromDateTime() + " and " + schedule.getWorkScheduleToDateTime() + " and "+schedule.getWorkScheduleStatus());
}
}
}
@Override
public void onFailure(Call<List<Schedule>> call, Throwable t) {
}
});
String asd = ""+variablesHolder.getBranchIdList();
Log.d(TAG, "onCreateView: "+asd);
}
public void buildRecyclerView(){
mScheduleList = mView.findViewById(R.id.rvScheduleList);
mScheduleList.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(mView.getContext());
mAdapter = new ScheduleAdapter(scheduleList);
mScheduleList.setLayoutManager(mLayoutManager);
mScheduleList.setAdapter(mAdapter);
mAdapter.setOnItemClickListener(new ScheduleAdapter.OnItemClickListener() {
@Override
public void onItemClick(int position) {
changeItem(position, "Clicked");
}
});
}
public void changeItem(int position, String text){
scheduleList.get(position).changeText1(text);
mAdapter.notifyItemChanged(position);
Log.d(TAG, "changeItem: "+position+" / "+text);
}
}
我的日程安排类（我目前只在其中使用 3 个变量）workfromtime、worktotime 和 workstatus
public class Schedule {
private String workScheduleID;
private Date workScheduleFromDateTime;
private Date workScheduleToDateTime;
private String workScheduleStatus;
private String workDescriptionID;
private String branchID;
private String staffID;
private String managerID;
private String workScheduleBidDateTime;
public Schedule(Date workScheduleFromDateTime, Date workScheduleToDateTime,String workScheduleStatus) {
this.workScheduleFromDateTime = workScheduleFromDateTime;
this.workScheduleToDateTime = workScheduleToDateTime;
this.workScheduleStatus = workScheduleStatus;
}
public void changeText1(String workScheduleStatus){
this.workScheduleStatus = workScheduleStatus;
}
public String getWorkScheduleID(){return workScheduleID;}
public Date getWorkScheduleFromDateTime(){return workScheduleFromDateTime;}
public Date getWorkScheduleToDateTime(){return workScheduleToDateTime;}
public String getWorkScheduleStatus(){return workScheduleStatus;}
public String getWorkDescriptionID(){return workDescriptionID;}
public String getBranchID(){return branchID;}
public String getStaffID(){return staffID;}
public String getManagerID(){return managerID;}
public String getWorkScheduleBidDateTime(){return workScheduleBidDateTime;}
}
适配器类
public class ScheduleAdapter extends RecyclerView.Adapter<ScheduleAdapter.ScheduleViewHolder> {
private static final String TAG = "ScheduleAdapter";
private ArrayList<Schedule> mScheduleList;
private OnItemClickListener mListener;
public interface OnItemClickListener{
void onItemClick(int position);
}
public void setOnItemClickListener(OnItemClickListener listener){
mListener = listener;
}
public static class ScheduleViewHolder extends RecyclerView.ViewHolder{
public TextView FromTime,ToTime,ScheduleStatus,Tester;
public ScheduleViewHolder(@NonNull final View itemView, final OnItemClickListener listener) {
super(itemView);
FromTime = itemView.findViewById(R.id.tvFromTime);
ToTime = itemView.findViewById(R.id.tvToTime);
ScheduleStatus = itemView.findViewById(R.id.tvStatus);
Tester = itemView.findViewById(R.id.tvTest);
itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(listener != null){
int position = getAdapterPosition();
if(position != RecyclerView.NO_POSITION){
listener.onItemClick(position);
}
}
}
});
}
}
public ScheduleAdapter(ArrayList<Schedule> scheduleList ){
mScheduleList = scheduleList;
}
@NonNull
@Override
public ScheduleViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View mView = LayoutInflater.from(parent.getContext()).inflate(R.layout.schedule_item,parent,false);
ScheduleViewHolder svh = new ScheduleViewHolder(mView, mListener);
return svh;
}
@Override
public void onBindViewHolder(@NonNull ScheduleViewHolder holder, int position) {
Schedule currentSchedule = mScheduleList.get(position);
Log.d(TAG, "onBindViewHolder: "+currentSchedule.getWorkScheduleFromDateTime() + " and "+currentSchedule.getWorkScheduleToDateTime());
String FromTimeRegion = currentSchedule.getWorkScheduleFromDateTime().toString().replace("GMT 2020","");
String ToTimeRegion = currentSchedule.getWorkScheduleToDateTime().toString().replace("GMT 2020","");
String status = currentSchedule.getWorkScheduleStatus();
Log.d(TAG, "onBindViewHolder: "+status);
if(status.toLowerCase().equals("pending")) {
holder.ScheduleStatus.setText("Pending");
holder.ScheduleStatus.setTextColor(Color.parseColor("#FFFF00"));
}
if(status.toLowerCase().equals("not taken")) {
holder.ScheduleStatus.setText("Not Taken");
holder.ScheduleStatus.setTextColor(Color.parseColor("#7FFF00"));
}
holder.FromTime.setText("From: "+FromTimeRegion);
holder.ToTime.setText("To: "+ToTimeRegion);
}
@Override
public int getItemCount() {
return mScheduleList.size();
}
}
请指教。
