如何获取文档文件的内部共享存储和sd卡文件路径？

Question

我正在尝试从内部共享存储和 SD 卡获取视频的文件路径。

我已将视频随机保存在内部共享存储和外部存储的随机文件夹中。

  public ArrayList<String> getVideosPath(Activity activity,Context context)
{
    listOfAllImages = new ArrayList<String>();
    Cursor cursor;

    final String[] columns = {MediaStore.Video.Media.DATA, MediaStore.Video.Media._ID};
    final String orderBy = MediaStore.Video.Media._ID;
    //Stores all the images from the gallery in Cursor
    cursor = getContentResolver().query(
            MediaStore.Video.Media.EXTERNAL_CONTENT_URI, columns, null,
            null, orderBy);
    //Total number of images
    int count = cursor.getCount();

    //Create an array to store path to all the images
    String[] arrPath = new String[count];

    for (int i = 0; i < count; i++) {
        cursor.moveToPosition(i);
        int dataColumnIndex = cursor.getColumnIndex(MediaStore.Video.Media.DATA);

        //Store the path of the image
        arrPath[i] = cursor.getString(dataColumnIndex);


        Bitmap thumb = ThumbnailUtils.createVideoThumbnail(arrPath[i],
                MediaStore.Images.Thumbnails.MINI_KIND);

//        BitmapFactory.Options options = new BitmapFactory.Options();
//        options.inSampleSize = 4;
//        Bitmap b = BitmapFactory.decodeFile(arrPath[i], options);



        bitmap.add(thumb);
      //  drawimages_onvideo.add(thumb);
        Log.i("PATH", arrPath[i]);
        listOfAllImages.add(arrPath[i]);
    }

虽然是从sd卡和phone存储中获取文件，但是路径不同

例如有 2 个视频文件，一个在 android 存储中，一个在 sd 卡中，路径为

android 存储空间：/storage/emulated/0/Movies/videoplay.mp4

和

sd 卡：/storage/BBF7-A8D2/videos/videoplay.mp4

我正在获取这 2 个文件，但显示给我的路径是：

/storage/emulated/0/Movies/videoplay.mp4
/storage/emulated/0/Movies/videoplay.mp4

怎么了？

这给了我所需的文档文件，从堆栈流链接之一获得了帮助。

            int count = fileCursor.getCount();

            //Create an array to store path to all the documents
            String[] arrPath = new String[count];

            for (int i = 0; i < count; i++) {

                int dataColumnIndex = fileCursor.getColumnIndex(MediaStore.Files.FileColumns.DATA);

                arrPath[i] = fileCursor.getString(dataColumnIndex);

                Bitmap b = ((BitmapDrawable) ResourcesCompat.getDrawable(this.getResources(), R.drawable.documentfile, null)).getBitmap();
