小编Alm*_*ett的帖子

我需要使用具有图像改造2.0和一些键值参数发送multipart请求:"key1" - "parameter1","key2" - "parameter2"等,但也有使用相同的密钥参数: "somepar[]" - "text1","somepar[]" - "text2"...我不能使用@PartMap这个结构:

@Multipart
@POST(myUrlPart)
Call<ClassEntity> myRequest(@Header("Authorization") String authHeader,
                                @Part("image\"; filename=\"image.png\"") RequestBody image,
                                @PartMap Map<String, RequestBody> params); 

因为Map <>无法使用相同的键存储多个值.而我无法使用

@Part("somepar[]") List<String> mylist  

要么

@Part("somepar[]") String[] myArray  

因为它会发送键值"somepar[]" - "{"1","2","3"}",不"somepar[]" = "1" , "somepar[]" = "2" ,"somepar[]" = "3".

请帮忙,如何提出这样的要求.

我想将android.permission.CHANGE_CONFIGURATION授予我的 apk 文件。

我使用的 adb 命令：

adb shell pm grant myPackageName android.permission.CHANGE_CONFIGURATION

但总是一次又一次出现同样的错误：

不允许操作：java.lang.SecurityException：myPackageName 未请求权限 android.permission.CHANGE_CONFIGURATION

清单.xml

<uses-sdk 
    android:minSdkVersion="14" 
    android:targetSdkVersion="22"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" /> 

已授予权限：

解决这个问题的办法是什么？谷歌上的帖子对我没有帮助。提前致谢。

我一直在努力通过Android Retrofit + SpringMVC实现个人资料照片上传功能.Java服务器无法响应Retrofit API调用.相关代码段如下:

ApiInterface

@Multipart
@POST("user/profileImage")
Call<ResponseBody> uploadImage(@Part MultipartBody.Part image, @Part("name") RequestBody name);

uploadToServer

public void uploadToServer(){
    //Get retrofit client
    Retrofit retrofit = ApiClient.getClient();
    //Get API interface
    ApiInterface apiInterface = retrofit.create(ApiInterface.class);
    // Get image parts
    MultipartBody.Part imageParts = bitmapToMultipart(imageBitmap);
    //Get image name
    RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "ProfileImage");
    //Call image upload API
    Call<ResponseBody> call = apiInterface.uploadImage(imageParts,name);
    call.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            ResponseBody body = response.body();
        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) …

我有一个项目列表,包括数字和字母,如下所示:

原始清单:

Apple 1B
Apple 1D
Apple 2A
Apple 2A
Apple 1C
Apple 1B

Apple 10
Apple 11
Apple 5
Apple 11
Apple 8D
Banana 1
Banana 4
Banana 9D
Banana 9E
Banana 9C
Banana 13
Banana 16

这是从API搜索结果,只能通过字母顺序进行排序Apples和Bananas.现在我想用数字(数字随机带字母A,B,C,D,E)对它进行排序,如下所示:

带有A,B,C,D,E字母的数字应按数字和字母顺序排序.

预期清单:

Apple 1

我正在使用 SimpleBluetoothLibrary 访问我的蓝牙打印机。现在我可以搜索可用设备，从列表中选择蓝牙打印机，连接到打印机。这些部分已完成。但我不知道如何将数据发送到打印机进行打印作业.这是onDeviceConnected方法。我从中获得了设备地址。但我想将数据发送到打印机。

@Override
            public void onDeviceConnected(BluetoothDevice device) {
                //a device is connected so you can now send stuff to it
                mTxt.setText("Connection Status:Connected:" + device.getAddress());

                Log.d("Mac_Address", device.getAddress());


            }
