Question

好的家伙，所以在花了一天试图弄清楚如何上传图片到解析服务器后，我终于决定寻求你的帮助。我没有找到关于如何做到这一点的完整示例。

我希望能做的是：

从图库中选择图片（已经这样做了）
加载到inageView（已经这样做）
在onClick事件中将所选图片上传到Parse服务器（我的问题）

到目前为止，您有我的代码段，但它无效。

private static int RESULT_LOAD_IMAGE = 1;


mSubmitJobBTN.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            createJob(); //this method will send data to Parse

        }
    });


private void addJob(final String mUsernameText, String mJobNameText,
        String mJobDescriptionText, String mJobPriceText) {

    /*Bitmap bitmap = BitmapFactory.decodeFile("picturePath");
    // Convert it to byte
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    // Compress image to lower quality scale 1 - 100
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] image = stream.toByteArray();

    try {
        image = readInFile(path);
    } catch (Exception e) {
        e.printStackTrace();
    }*/

    ParseUser user = ParseUser.getCurrentUser();

    anunt.put("username", "andrei");
    anunt.put("jobName", mJobNameText);
    anunt.put("jobDescription", mJobDescriptionText);
    anunt.put("jobPrice", mJobPriceText);



    /*// Create a column named "jobPicture" and set the string
    anunt.put("jobPicture", "picturePath");

    // Create the ParseFile
    ParseFile file = new ParseFile("picturePath", image);
    // Upload the image into Parse Cloud
    file.saveInBackground();

    // Create a column named "ImageFile" and insert the image
    anunt.put("ImageFile", file);*/


    anunt.saveInBackground(new SaveCallback() {
        public void done(ParseException e) {
            if (e == null) {
                Toast.makeText(getApplicationContext(),
                        "Job succesfully posted!", Toast.LENGTH_LONG)
                        .show();
                Intent in = new Intent(getApplicationContext(),
                        JobsListActivity.class);
                in.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(in);
                finish();

            } else {

                Toast.makeText(getApplicationContext(),
                        "Sign up error, please check all the fields",
                        Toast.LENGTH_LONG).show();
            }
        }

    });
}


    public byte[] readInFile(String path) throws IOException {
    byte[] data = null;
    File file = new File(path);
    InputStream input_stream = new BufferedInputStream(new FileInputStream(
            file));
    ByteArrayOutputStream buffer = new ByteArrayOutputStream();
    data = new byte[16384]; // 16K
    int bytes_read;
    while ((bytes_read = input_stream.read(data, 0, data.length)) != -1) {
        buffer.write(data, 0, bytes_read);
    }
    input_stream.close();
    return buffer.toByteArray();

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
            && null != data) {
        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        PreferenceManager.getDefaultSharedPreferences(this).edit()
                .putString("picturePath", picturePath).commit();
        cursor.close();

        ImageView imageView = (ImageView) findViewById(R.id.addJob_imageView);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }

您应该使用PHP或任何服务器脚本将图像从android上传到服务器。请尝试下面给出的网址

这就是答案！

 ByteArrayOutputStream stream = new ByteArrayOutputStream();
                    // Compress image to lower quality scale 1 - 100
                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
                    byte[] imagez = stream.toByteArray();

                    ParseFile filez = new ParseFile("androidbegin.png",
                            imagez);

                    filez.saveInBackground();

                    imgupload = new ParseObject("Anunturi");

                    imgupload.put("JobPictureName", "AndroidBegin Logo");

                    imgupload.put("jobPicture", filez);

                    imgupload.put("jobPictureName", picturePath);
                    imgupload.put("username", mUsernameText);
                    imgupload.put("jobName", mJobNameText);

                    });

使用Parse作为后端上传/保存所选图像
