Android 从内部存储器设置图像位图

如何从内部存储器设置图像位图？我检查了我的代码和图像是否存放在内存中，但是函数SetImageBitmap有问题，有什么帮助吗？下面是我的代码，请拍照并保存到内部存储器

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1) {
            if (resultCode == Activity.RESULT_OK) {
                 String filename=currentImagePath.substring(currentImagePath.lastIndexOf("/")+1);

                imageView.setImageBitmap(BitmapFactory.decodeFile(filename));
                }
            }
        }


        public void takepicture() { 

        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

        if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
            File photoFile = null;
            try {
                photoFile = imageFile();
                currentImagePath = photoFile.getAbsolutePath();
            } catch (IOException ex) {
                ex.fillInStackTrace();
            }
            if (photoFile != null) {
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
                startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
            }
        }
    }

    @SuppressLint("SimpleDateFormat")
    private File imageFile() throws IOException {
        // Create an image file name
        SimpleDateFormat DATE_FORMAT = new SimpleDateFormat(Constants.DEFAULT_DATETIME_FORMAT);
        String imageFileName = DATE_FORMAT.format(new Date());

        ContextWrapper cw = new ContextWrapper(getActivity());
        File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);

        FileOperations.checkDirectory(directory, false);

        return File.createTempFile(imageFileName, ".jpg", directory);
    }
}

您正在尝试将图像存储在内部的外部路径？？中：ContextWrapper cw=new ContextWrapper（getActivity（））；File directory=cw.getDir（“imageDir”，Context.MODE\u PRIVATE）；你的代码会产生错误吗？？如果是，请填写日志您是否使用了getexterstore功能对不起，您可以详细解释一下吗？
