Question

我想将图片上传到parse.com。我从图库中选择图像并将其放在活动A中的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：

@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();

        }

然后我通过Intent发送字节数组：

intent.putExtra("Image",byteArray);

现在在活动B中：

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


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

最后我发送它来解析如：

listedProperty.put("PropPic", file);

从那以后，数据没有进入我的parse类，我从parse得到一个不成功的回调。可能有什么不对？

logcat的：

Answer 1

不确定这是否有帮助，但我将我的位图图像保存为这样解析，这是在用相机拍照后。

@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();
    }
}

我的项目中有类似的代码，我用Parse保存用户的图像并在Parse ImageView中显示，它可以工作：

 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();
    }

}

在Parse.com上保存图像
