Question

我从fabric.io那里得到了很多时间。但是我的测试没有在我的手机上发生任何故障，所以我并没有找到解决方案这个错误。

我很快从图库中选择图像，然后用户裁剪此图像并将此文件资源设置为imageview。

我也使用这个裁剪图像库。 https://github.com/lvillani/android-cropimage

我从那里打电话

 profileImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivityForResult(MediaStoreUtils.getPickImageIntent(MainActivity.this), REQUEST_PICTURE);
        }

    });

public static Intent getPickImageIntent(final Context context) {
    final Intent intent = new Intent();
    intent.setType("image/*");

    intent.setAction(Intent.ACTION_GET_CONTENT);

    return Intent.createChooser(intent, "Select picture");
}

的onCreate

File Folder = new File(Environment.getExternalStorageDirectory() + "/folder/");
    croppedImageFile = new File(Environment.getExternalStorageDirectory() + "/folder/test.jpg");
    if (!Folder.exists()) {
        Folder.mkdirs();
        File noMedia = new File(Environment.getExternalStorageDirectory() + "/folder" + "/.nomedia");
        try {
            noMedia.createNewFile();
            croppedImageFile.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

onActivityResult

 protected void onActivityResult(int requestCode, int resultCode,
                                Intent imageReturnedIntent) {

    super.onActivityResult(requestCode, resultCode, imageReturnedIntent);


    if ((requestCode == REQUEST_PICTURE) && (resultCode == RESULT_OK)) {
        Uri croppedImage = Uri.fromFile(croppedImageFile);
        CropImageIntentBuilder cropImage = new CropImageIntentBuilder(200, 200, croppedImage);
        cropImage.setOutlineColor(0xFF03A9F4);
        cropImage.setSourceImage(imageReturnedIntent.getData());

        startActivityForResult(cropImage.getIntent(this), REQUEST_CROP_PICTURE);
    } else if ((requestCode == REQUEST_CROP_PICTURE) && (resultCode == RESULT_OK)) {

        profileImage.setImageBitmap(BitmapFactory.decodeFile(croppedImageFile.getAbsolutePath()));
        profileImage.setTag(Constants.IMAGE_IS_DEFINED);
    }

Answer 1

好像你没有正确设置结果代码：

ResultInfo{who=null, request=2, result=-1, data=Intent { act=file:///storage/sdcard0/folder/test.jpg (has extras) }}

result=-1通常表示错误，因此无论您在何处调用Intent，都可能出错。

也许你没有设定最好的结果。你必须这样做： setResult(Activity.RESULT_OK, yourData);

who=null似乎Activity发回的结果是null，但它确实没有多大意义。

java.lang.RuntimeException：传递结果失败ResultInfo
