获取输出裁剪图像 URI

Question

我在我的应用程序中使用 android 意图实现了图像裁剪，如下所示：

CropIntent = new Intent("com.android.camera.action.CROP");

我已收到裁剪后的图像并显示在我的 UI 上，但我想执行更多用例，例如上传裁剪后的图像 uri。问题是 activity.

中没有返回 uri

这是我的裁剪图像意图片段：

galleryFAB.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Log.d(TAG, "Gallery Btn Clicked");
            selectFromGallery();
        }
    });

private void selectFromGallery() {

    galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
    galleryIntent.setType("image/*");
    startActivityForResult(Intent.createChooser(galleryIntent, "Choose From"), 2);
}

我的代码在 activity 结果方法中：

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

    InputStream inputStream;

    if (requestCode == 2 && resultCode == RESULT_OK){
        if (data != null){
            cropImageUri = data.getData();
            userImage.setImageURI(cropImageUri);
            try {
                originalBitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), cropImageUri);

                inputStream = getContentResolver().openInputStream(data.getData());
                originalBitmap = BitmapFactory.decodeStream(inputStream);

                Log.d(TAG, "Original bitmap byte count is:\t" + originalBitmap.getByteCount());

                resizedBitmap = getResizedBitmap(originalBitmap, 200);

                ByteArrayOutputStream stream = new ByteArrayOutputStream();
                resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);

                Log.d(TAG, "Resized bitmap byte count is:\t" + resizedBitmap.getByteCount());

                try {
                    File file = saveBitmap("avatar_image");
                    upLoadFile(file);
                } catch (IOException ex) {
                    ex.printStackTrace();
                }


                byte[] bytes = stream.toByteArray();

                /**
                 *   For Shared Preferences
                 * **/

                encodedImage = Base64.encodeToString(bytes, Base64.DEFAULT);

                imagePrefs = getSharedPreferences("ImagePrefs", Context.MODE_PRIVATE);
                SharedPreferences.Editor editor = imagePrefs.edit();
                editor.putString("image_user", encodedImage).commit();

                upLoadBytes(bytes);

            } catch (IOException e) {
                e.printStackTrace();
            }

            cropImage();
        }

    } else if (requestCode == PERM_CODE){
        if (data != null){

            //I want to get the cropped image uri here but unable to. Have tried converting the bitmap rcvd here to uri but in activity, ntn is returned. kindly guide me

            Bundle bundle = data.getExtras();
            originalBitmap = bundle.getParcelable("data");
            userImage.setImageBitmap(resizedBitmap);
        }

    }

}

我的裁剪图像功能：

private void cropImage() {
    try {
        CropIntent = new Intent("com.android.camera.action.CROP");

        CropIntent.setDataAndType(cropImageUri, "image/*");
        CropIntent.putExtra("crop", true);
        CropIntent.putExtra("outputX", 200);
        CropIntent.putExtra("outputY", 200);
        CropIntent.putExtra("aspectX", 1);
        CropIntent.putExtra("aspectY", 1);
        CropIntent.putExtra("scale", true);
        CropIntent.putExtra("return-data", true);

        startActivityForResult(CropIntent, PERM_CODE);


    } catch (ActivityNotFoundException ex){

    }
}

谁能说说如何获取输出uri？谢谢

如果裁剪后的图像显示在 ImageView 中，请按照 this link 将其保存到设备存储，然后您可以上传文件。
