在我的应用程序中,我希望在RestfulController
中显示一些数据,并从服务器获取此数据。
我使用recyclerView
从发送或获取请求从android到服务器。
运行应用程序时,它显示Retrofit
0 ,但在 PostMan 中,我看到以下数据:
我在下面写了获取数据的代码:
response.body().getData().size()
显示此private void getComments() {
CommentSendData sendData = new CommentSendData();
sendData.setEntityID(7);
sendData.setReviewType(5);
sendData.setReviewUserType(0);
sendData.setEntityID(newsID);
sendData.setCelebrityID(0);
sendData.setPageIndex(0);
sendData.setPageSize(10);
InterfaceApi api = ApiClient.getClient().create(InterfaceApi.class);
Call<CommentResponse> call = api.getComments(sendData);
call.enqueue(new Callback<CommentResponse>() {
@Override
public void onResponse(Call<CommentResponse> call, Response<CommentResponse> response) {
Toast.makeText(NewsDetailActivity.this, "" + response.body().getData().size(), Toast.LENGTH_SHORT).show();
Toast.makeText(NewsDetailActivity.this, "" + call.isExecuted(), Toast.LENGTH_SHORT).show();
}
@Override
public void onFailure(Call<CommentResponse> call, Throwable t) {
}
});
}
时:Toast
在Toast.makeText(NewsDetailActivity.this, "" + call.isExecuted(), Toast.LENGTH_SHORT).show();
中向我显示 true 。
当显示此toast
:Toast
时,请在Toast.makeText(NewsDetailActivity.this, "" + response.body().getData().size(), Toast.LENGTH_SHORT).show();
中显示 0 。
我的适配器代码:
toast
CommentResponse代码:
public class CommentsListAdapter extends RecyclerView.Adapter<CommentsListAdapter.ViewHolder> {
private Context context;
private List<CommentData> model;
public CommentsListAdapter(Context context, List<CommentData> model) {
this.context = context;
this.model = model;
}
@Override
public CommentsListAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_comment, parent, false);
return new CommentsListAdapter.ViewHolder(view);
}
@Override
public void onBindViewHolder(final CommentsListAdapter.ViewHolder holder, final int position) {
holder.row_commentNameTxt.setText(Html.fromHtml(model.get(position).getOwner().getName()));
holder.row_commentCommentTxt.setText(Html.fromHtml(model.get(position).getText()));
Glide.with(context)
.load(model.get(position).getOwner().getImageUrl())
.placeholder(R.drawable.default_image)
.diskCacheStrategy(DiskCacheStrategy.ALL)
.listener(new RequestListener<String, GlideDrawable>() {
@Override
public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
return false;
}
@Override
public boolean onResourceReady(GlideDrawable resource, String model,
Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
return false;
}
})
.into(holder.row_commentProfileImage);
holder.row_commentLikeTxt.setText(model.get(position).getLikeCount() + "");
holder.row_commentReplayTxt.setText(model.get(position).getRepliesCount() + "");
holder.row_commentDateTxt.setText(model.get(position).getSubmitDate() + " " + model.get(position).getSubmitTime());
}
@Override
public int getItemCount() {
return model.size();
}
public void addNewItem(List<CommentData> newContent) {
int start = this.model.size();
int end = newContent.size();
model.addAll(newContent);
notifyDataSetChanged();
}
public void clear() {
model.clear();
notifyDataSetChanged();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private CircleImageView row_commentProfileImage;
private TextView row_commentNameTxt, row_commentCommentTxt, row_commentLikeTxt, row_commentReplayTxt, row_commentDateTxt;
public ViewHolder(View itemView) {
super(itemView);
row_commentProfileImage = (CircleImageView) itemView.findViewById(R.id.row_commentProfileImage);
row_commentNameTxt = (TextView) itemView.findViewById(R.id.row_commentNameTxt);
row_commentCommentTxt = (TextView) itemView.findViewById(R.id.row_commentCommentTxt);
row_commentLikeTxt = (TextView) itemView.findViewById(R.id.row_commentLikeTxt);
row_commentReplayTxt = (TextView) itemView.findViewById(R.id.row_commentReplayTxt);
row_commentDateTxt = (TextView) itemView.findViewById(R.id.row_commentDateTxt);
}
}
}
CommentData模型:
public class CommentResponse {
@SerializedName("statusCode")
@Expose
private Integer statusCode;
@SerializedName("statusMessage")
@Expose
private String statusMessage;
@SerializedName("data")
@Expose
private List<CommentData> data = null;
public Integer getStatusCode() {
return statusCode;
}
public void setStatusCode(Integer statusCode) {
this.statusCode = statusCode;
}
public String getStatusMessage() {
return statusMessage;
}
public void setStatusMessage(String statusMessage) {
this.statusMessage = statusMessage;
}
public List<CommentData> getData() {
return data;
}
public void setData(List<CommentData> data) {
this.data = data;
}
}
为什么在运行应用程序时显示 0 数据但在 PostMan 显示数据?
答案 0 :(得分:1)
可能有几个原因
1。)键入基本URL或辅助URL时可能会出现一些错误。请交叉检查。并检查“/”在基本URL之后出现的另一个问题,因此不需要在辅助URL之前使用它。
2.请交叉检查有效载荷,因为它们必须准确无误。如果您不知道如何创建准确的有效负载,请遵循此spinet。
private JsonObject makeJsonObjectPayload() {
JsonObject requestBean = new JsonObject();
requestBean.addProperty("key", value);
requestBean.addProperty("key", value);
requestBean.addProperty("key", value);
requestBean.addProperty("key", value);
requestBean.addProperty("key", value);
return requestBean;
}
3.如果您没有注意到您没有更新回收站视图中的数据。因此,请使用addNewItem(List<CommentData> newContent)
方法更新数据。

看起来你正在以错误的方式将一些数据传递给服务器。您确定从POSTMAN发送的数据与从Retrofit发送的数据相同吗?
您可以发布api.getComments(sendData)
方法的实现吗?
