无法在android中使用解析api在解析服务器中上载图像

我尝试从gallery中选择一幅图像，并保存在android的parse cloud server中。 但是我做不到

我尝试了以下代码：

OnImageView单击事件选择图像：

imageDish.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            try {
                Intent intent = new Intent();
                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(
                        Intent.createChooser(intent, "Select Picture"),
                        SELECT_PICTURE);
            } catch (Exception e) {
                Toast.makeText(getActivity(),
                        "Select Image From Gallery", Toast.LENGTH_LONG)
                        .show();
                // TODO: handle exception
            }

        }
    });

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

    if (resultCode == Activity.RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {
            selectedImageUri = data.getData();

            selectedImagePath = getPath(selectedImageUri);
            System.out.println("Image Path : " + selectedImagePath);
            imageDish.setImageURI(selectedImageUri);
        }
    }
}

public String getPath(Uri uri) {
    String[] projection = {MediaStore.Images.Media.DATA};
    Cursor cursor = getActivity().managedQuery(uri, projection, null, null, null);
    int column_index = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);

}

 InputStream imageStream = null;
    try {
                imageStream = getActivity().getContentResolver().openInputStream(
                        selectedImageUri);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }

            Bitmap bitmap = BitmapFactory.decodeStream(imageStream);
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            // Compress image to lower quality scale 1 - 100
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byte[] image = stream.toByteArray();
            ParseFile file = new ParseFile("FoodImage", image);
            // Upload the image into Parse Cloud
            file.saveInBackground();
            Log.d("File======", "" + file);



      try {
                ParseObject Foodobject = new ParseObject("Food");
                Foodobject.put("FoodName", Name);
                Foodobject.put("ResId", ParseObject.createWithoutData("Restaurant",Res_id);
                Foodobject.put("FoodCategory", ParseObject.createWithoutData("FoodCategory", _CategoryId));
                Foodobject.put("FoodDesc", Des);
                Foodobject.put("Price",priceNumber);
                Foodobject.put("VegOnly", "Y");
                Foodobject.put("IsRecommended", false);
                Foodobject.put("FoodImage", file);
                Foodobject.saveInBackground();
               } catch (Exception ex) {
                Log.e("Error", "" + ex);
            }

OnActivityResult:

imageDish.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            try {
                Intent intent = new Intent();

                startActivityForResult(
                        Intent.createChooser(intent, "Select Picture"),
                        SELECT_PICTURE);
            } catch (Exception e) {
                Toast.makeText(getActivity(),

    });

    if (resultCode == Activity.RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {
            selectedImageUri = data.getData();

            selectedImagePath = getPath(selectedImageUri);
            System.out.println("Image Path : " + selectedImagePath);
            imageDish.setImageURI(selectedImageUri);
        }
    }

分析保存图像的代码：

               } catch (Exception ex) {
                Log.e("Error", "" + ex);
            }

文件===：com.parse。ParseFile@39f19700

用这个替换你的代码

ParseFile file = new ParseFile("FoodImage.png", image);

在parse docs中，我们清楚地提到，您为具有文件扩展名的文件命名。这使Parse能够找出文件类型并相应地处理它。

---

我认为您的图像大小问题，可能是您从gallery中选择的图像太大，无法保存在parse.com中

所以试试这个代码

它对我有用

                ByteArrayOutputStream stream = null;
                Bitmap bitmap = BitmapFactory.decodeFile(picturePath)
                Bitmap newbitmap = Bitmap.createScaledBitmap(bitmap, 200, 200, true);
                stream = new ByteArrayOutputStream();   
                newbitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);

            byte[] image = stream.toByteArray();
            final ParseFile file = new ParseFile("FoodImage.png", image);
            file.saveInBackground(new SaveCallback() {
                @Override
                public void done(ParseException e) {
                    if(e==null){
                     // Your Parse Code....
                      }
                  }

试试这个链接@NikitaSukhadiya是的！我尝试了…但不起作用…：-（那么什么不起作用呢？@Wain当我从图库中选择图像时，它没有存储在parse.but

Bitmap Bitmap=BitmapFactory.decodeResource（getResources（），R.mipmap.ic_启动器）中）

当写入直接资源映像时，它已成功保存！！！您如何测试它？该保存是异步的，我尝试了，但不起作用..当我从可绘图文件写入默认映像时，它已保存..您可以尝试位图Bitmap=BitmapFactory.decodeFile（selectedImagePath）吗；而不是位图位图=BitmapFactory.decodeStream（imageStream）；
