拍照后出现 "The following declarations have the same JVM signature" 错误，如何在 kotlin 上设置 onActivityResult？

Question

我正在尝试在从本地文件拍摄或附加照片后在 kotlin class 上设置 onActivityResult。 java 代码工作正常

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CameraService.REQUEST_IMAGE_CAPTURE) {
        if (resultCode == Activity.RESULT_OK) {
            photoList.add(mPhotoFile.toString());
        }
    }else{
        if (resultCode == Activity.RESULT_OK) {
            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 picturePath = cursor.getString(columnIndex);
            cursor.close();
            photoList.add(picturePath);
        }
    }
}

但是在 kotlin class 上，相同的代码块给我一个错误“以下声明具有相同的 JVM 签名”

这是科特林代码

private fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {
        if (requestCode == CameraService.REQUEST_IMAGE_CAPTURE) {
            if (resultCode == Activity.RESULT_OK) {
                photoList.add(mPhotoFile.toString())
            }
        } else {
            if (resultCode == Activity.RESULT_OK) {
                val selectedImage = data.data
                val filePathColumn = arrayOf(MediaStore.Images.Media.DATA)
                val cursor = contentResolver.query(selectedImage, filePathColumn, null, null, null)
                cursor.moveToFirst()
                val columnIndex = cursor.getColumnIndex(filePathColumn[0])
                val picturePath = cursor.getString(columnIndex)
                cursor.close()
                photoList.add(picturePath)
            }
        }
    }

错误是

任何帮助或建议都将非常感谢

您应该像这样更改您的代码

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {
        if (requestCode == CameraService.REQUEST_IMAGE_CAPTURE) {
            if (resultCode == Activity.RESULT_OK) {
                photoList.add(mPhotoFile.toString())
            }
        } else {
            if (resultCode == Activity.RESULT_OK) {
                val selectedImage = data.data
                val filePathColumn = arrayOf(MediaStore.Images.Media.DATA)
                val cursor = contentResolver.query(selectedImage, filePathColumn, null, null, null)
                cursor.moveToFirst()
                val columnIndex = cursor.getColumnIndex(filePathColumn[0])
                val picturePath = cursor.getString(columnIndex)
                cursor.close()
                photoList.add(picturePath)
            }
        }
    }

片段onActivityResult方法中，data参数可以为空，所以必须使用data: Intent?:

private fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    // your code here
}
