Question

这是我的json：

{
  "status": "success",
  "data": {
    "totalEstimation": 15,
    "completed": 0,
    "pending": 15,
    "daily_effort": [
      {
        "taskName": "in progress",
        "projectName": "Test Project",
        "estimatedTime": "30",
        "timeLog": "15",
        "estimationVariation": 50
      },
      {
        "taskName": "po review",
        "projectName": "Test Project",
        "estimatedTime": "30",
        "timeLog": "45",
        "estimationVariation": 150
      }
    ]
  }
}

我的模特课是：

public class ProfileResponse {
    @SerializedName("status")
    @Expose
    private String status;
    @SerializedName("data")
    @Expose
    private Data data;
    // getter and setter
}

public class Data {
    @SerializedName("totalEstimation")
    @Expose
    private Integer totalEstimation;
    @SerializedName("completed")
    @Expose
    private Integer completed;
    @SerializedName("pending")
    @Expose
    private Integer pending;
    @SerializedName("daily_effort")
    @Expose
    private List<DailyEffort> dailyEffort = null;
    //getter and setter
}

public class DailyEffort {
    @SerializedName("taskName")
    @Expose
    private String taskName;
    @SerializedName("projectName")
    @Expose
    private String projectName;
    @SerializedName("estimatedTime")
    @Expose
    private String estimatedTime;
    @SerializedName("timeLog")
    @Expose
    private String timeLog;
    @SerializedName("estimationVariation")
    @Expose
    private Integer estimationVariation;
    // getter and setter
}

我的适配器类：

public class ProfileAdapter extends RecyclerView.Adapter<ProfileAdapter.MyViewHolderClass> {
private Context context;
private List<DailyEffort> dailyEffortList = new ArrayList<>();

public ProfileAdapter(Context context, List<DailyEffort> dailyEffortList) {
    this.context = context;
    this.dailyEffortList = dailyEffortList;
}

@Override
public MyViewHolderClass onCreateViewHolder(ViewGroup parent, int viewType) {
    View profileContainer = LayoutInflater.from(parent.getContext()).inflate(R.layout.fragment_profile_item, parent, false);
    return new MyViewHolderClass(profileContainer);
}

@Override
public void onBindViewHolder(MyViewHolderClass holder, int position) {
    DailyEffort dailyEffort = dailyEffortList.get(position);
    holder.taskName.setText(dailyEffort.getTaskName());
    holder.projectName.setText(dailyEffort.getProjectName());
    holder.timeLog.setText(dailyEffort.getTimeLog());
    boolean estimationVariation = dailyEffort.getEstimationVariation() >= 0;
    if (estimationVariation) {
        holder.estimationUp.setVisibility(View.VISIBLE);
        holder.estimationUp.setText("+" + dailyEffort.getEstimationVariation() + "");
    } else {
        holder.estimationDown.setVisibility(View.VISIBLE);
        holder.estimationDown.setText("-" + dailyEffort.getEstimationVariation() + "");
    }

}

@Override
public int getItemCount() {
    return dailyEffortList.size();
}


public class MyViewHolderClass extends RecyclerView.ViewHolder {
    @BindView(R.id.proTaskNameId)
    TextView taskName;
    @BindView(R.id.proProjectNameId)
    Button projectName;
    @BindView(R.id.proLogTimeId)
    Button timeLog;
    @BindView(R.id.proEstimationVariationUpId)
    Button estimationUp;
    @BindView(R.id.proEstimationVariationDownId)
    Button estimationDown;
    @BindView(R.id.proDividerLineId)
    View dividerLine;

    public MyViewHolderClass(View itemView) {
        super(itemView);
        ButterKnife.bind(this, itemView);
    }
}
}

在我的片段类中：

Call<ProfileResponse> profileResponseCall = profileService.profileContainer(preferenceClass.getLoginToken());
    profileResponseCall.enqueue(new Callback<ProfileResponse>() {
        @Override
        public void onResponse(Call<ProfileResponse> call, Response<ProfileResponse> response) {
            if (response.isSuccessful()){
                ProfileResponse profileResponse = response.body();
                if (profileResponse.getData() != null && profileResponse.getData().getDailyEffort() != null) {
                    profilePresenter.setDismiss();
                    logTime.setText("" + String.valueOf(profileResponse.getData().getTotalEstimation()) + " hrs");
                    completedTime.setText("" + String.valueOf(profileResponse.getData().getCompleted()) + " hrs");
                    pendingTime.setText("" + String.valueOf(profileResponse.getData().getPending()) + " hrs");

                    dailyEffortList = profileResponse.getData().getDailyEffort();


                    profileAdapter = new ProfileAdapter(getContext(), dailyEffortList);
                    recyclerViewProfile.setAdapter(profileAdapter);

                } 

            } 

        }

        @Override
        public void onFailure(Call<ProfileResponse> call, Throwable t) {

        }
    });

我正在从服务器获取记录时间，完成时间，待定时间。但是，RecyclerView没有显示。

当我使用log在控制台中查看结果时，它会显示数据。

Log.e(TAG, "onResponse: "+profileResponse.getData().getDailyEffort().get(0).getTaskName());
Log.e(TAG, "onResponse: "+profileResponse.getData().getDailyEffort().get(1).getTaskName());

屏幕截图如下：

列表结果位于此配置文件视图下方：图像，已记录/已完成/待处理任务，但我没有收到。

可以采取哪些措施来解决这个问题？

Answer 1

在setAdapter之前设置LayoutManager。

recyclerViewProfile.setLayoutManager(new LinearLayoutManager(getContext()));

使用改造2 android解析嵌套的json
