在Parse.com上保存圖像

Question

我想將圖像上傳到parse.com。 我從圖庫中選擇圖像，並將其放在活動A的ImageView中，如下所示：

addImage.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(i, RESULT_LOAD_IMAGE);
}
};

然后，在OnActivityforResult中：

@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) {
             mMediaUri = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

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

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

           // ImageView imageView = (ImageView) findViewById(R.id.imgView);
            propertyImage.setImageBitmap(BitmapFactory.decodeFile(picturePath));

            Bitmap bmp = BitmapFactory.decodeFile(picturePath);
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byteArray = stream.toByteArray();

        }

然后，我通過Intent發送字節數組：

intent.putExtra("Image",byteArray); 

現在處於活動B：

byte[] data = getIntent().getByteArrayExtra("Image");


        final ParseFile file = new ParseFile("propic.png", data);
        file.saveInBackground();

最后，我將其發送為解析：

listedProperty.put("PropPic", file);

從那時起，數據就沒有進入我的解析類，並且我從解析中獲得了失敗的回調。 有什么事嗎

Answer 1

不確定是否有幫助，但是我保存了位圖圖像以進行解析，這是在使用相機拍照后進行的。

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    byte[] image_byte_array;
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        post_object = new Post();
        Bundle extras = data.getExtras();
        image = (Bitmap) extras.get("data");
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        image.compress(Bitmap.CompressFormat.PNG, 100, stream);
        image_byte_array = stream.toByteArray();
        picture_file = new ParseFile("Picture", image_byte_array);
        picture_file.saveInBackground();
        post_object.put("Image", picture_file);
        post_object.saveInBackground();
    }
}

我在proyect中有一個類似的代碼，並以此將用戶的圖像保存在Parse上並在ParseImageView中顯示，並且它可以正常工作：

 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 filePath = cursor.getString(columnIndex);
        cursor.close();

        Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath);

        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        yourSelectedImage.compress(Bitmap.CompressFormat.PNG, 100, stream);
        // put on my imageview
     //   ImagenParseUserNavigation.setImageBitmap(yourSelectedImage);
     //   ImagenParseUser.setImageBitmap(yourSelectedImage);
        byte[] image = stream.toByteArray();


        ParseUser currentUser = ParseUser.getCurrentUser();
        ParseFile photoFile = new ParseFile("fotoperfil"+currentUser.getUsername()+".png",image);

        currentUser.put("Imagen", photoFile);
        currentUser.saveInBackground();
    }

}
