android - 如何将图像从图库上传到 Android 中的 Parse Server ..？

Question

这是我的代码

公共(public)类 TestingActivity 扩展 AppCompatActivity {

Button btn_testing;
ProgressDialog pDialog;
ImageView iv_image;
Bitmap bMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.testing);
    btn_testing = (Button)findViewById(R.id.btn_testing);
    iv_image = (ImageView)findViewById(R.id.iv_imagetesting);

    FileInputStream in;
    BufferedInputStream buf;


    try
    {
        in = new FileInputStream("/storage/emulated/0/Pictures/InstaTag_Edit_20160427_131230-346274175.jpg");
        buf = new BufferedInputStream(in,1070);
        System.out.println("1.................."+buf);
        byte[] bMapArray= new byte[buf.available()];
        buf.read(bMapArray);
         bMap = BitmapFactory.decodeByteArray(bMapArray, 0, bMapArray.length);
        iv_image.setImageBitmap(bMap);
        if (in != null)
        {
            in.close();
        }
        if (buf != null)
        {
            buf.close();
        }

    }
    catch (Exception e) {
        Log.e("Error reading file", e.toString());
    }
    btn_testing.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            pDialog = new ProgressDialog(TestingActivity.this);
            pDialog.setMessage("Loading...");
            pDialog.show();


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

            ParseFile file = new ParseFile("androidbegin.png", image,"image/png");
            file.saveInBackground(new SaveCallback() {
                @Override
                public void done(ParseException e) {
                    try {
                        pDialog.dismiss();
                    } catch (Exception e1) {
                    }
                    if (e == null) {
                        Toast.makeText(TestingActivity.this, "Image saved", Toast.LENGTH_LONG).show();
                    } else {
                        e.printStackTrace();
                        Toast.makeText(TestingActivity.this, "Image not saved", Toast.LENGTH_LONG).show();
                    }
                }
            });
        }
    });

改变这一行

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

到

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

你有没有添加这些行，

            ParseObject photo = new ParseObject("Photo");
            photo.put("fileFull", imgfile);
            photo.put("User", ParseUser.getCurrentUser());
            photo.saveInBackground();
