实际上，我是这个领域的新手。在图片上传过程中出现了一些问题。过了一段时间后，这个过程会自动暂停。我在下面附上我的代码。请任何人帮我解决这个问题。
ServerResponse.java
public class ServerResponse {
// variable name should be same as in the JSON response from PHP
@SerializedName("success")
boolean success;
@SerializedName("success_msg")
//@SerializedName("message")
String message;
String getMessage() {return message;
}
boolean getSuccess() {
return success;
}
}
ApiClient.java
public class ApiClient {
// public static final String BASE_URL="http://www.mytriangle.net16.net";

如果您的问题是隐藏了进度条，则表示您未在progressDialog.dismiss();函数中调用onFailure。
答案 1 :(得分：0)
您的文件应该像这样上传
File file1 = new File(mediaPath);
int id=24;
// File file2 = new File(mediaPath);
RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file1);
MultipartBody.Part body = MultipartBody.Part.createFormData("photo", file.getName(), requestFile);
RequestBody requestBodyid = RequestBody.create(MediaType.parse("multipart/form-data"),id);
ApiService getResponse = ApiClient.getClient().create(ApiService.class);
// Call<ServerResponse> call = getResponse.uploadFile(fileToUpload1);
Call<ServerResponse> call = getResponse.uploadFile(body,requestBodyid);
而不是
RequestBody requestBody1 = RequestBody.create(MediaType.parse("image/*"), file1);
编辑：您忘记为代码创建id.add请求正文。
RequestBody requestBodyid = RequestBody.create（MediaType.parse（＆＃34; multipart / form-data＆＃34;），id）;
其中id是你的id，即id = 24。
