android - 录制视频并保存在 SD 卡中

Question

我拍照并将其保存到外部存储:

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            File photoFile = getPhotoFile();

            String authorities = getActivity().getPackageName() + ".fileprovider";
            imageUri = FileProvider.getUriForFile(getActivity(), authorities, photoFile);

            intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
            startActivityForResult(intent, 1);

效果不错但是录制视频呢
我写了一些这样的代码，但我认为它不正确:

            Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
            File videoFile = getVideoFile();

            String authorities = getActivity().getPackageName() + ".fileprovider";
            videoUri = FileProvider.getUriForFile(getActivity(), authorities, videoFile);

            intent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri);
            startActivityForResult(intent, 2);

我能做什么？

编辑:这些方法创建一个目录并返回照片和视频文件

public File getPhotoFile() {
    //create a random name
    String randomName = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
    File mainPath = new File(path, "/Images");

    if (!mainPath.exists()) {

        mainPath.mkdirs();
    }

    File photoPath = new File(mainPath, randomName + ".jpg");
    return photoPath;
}

public File getVideoFile() {
    //create a random name
    String randomName = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
    File mainPath = new File(path, "/Videos");

    if (!mainPath.exists()) {

        mainPath.mkdirs();
    }

    File photoPath = new File(mainPath, randomName + ".mp4");
    return photoPath;
}

录制视频使用:

startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE);

这是一个 example
