如何从 onActivityResult Intent 获取视频缩略图？

Question

下面是我的代码，我从 ThumbnailUtils.createVideoThumbnail

得到一个空值

Intent takePicture = new Intent(Intent.ACTION_PICK, MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
takePicture.setType("video/*");
startActivityForResult(takePicture, 4);

我的视频文件选择意图的 OnResultActivity 代码：

if(requestCode == 4) {
    Uri selectedVideoUri = data.getData();
    Bitmap bitmap = ThumbnailUtils.createVideoThumbnail(selectedVideoUri.getPath(), MediaStore.Video.Thumbnails.MINI_KIND);
    Log.i("Video URI, ", String.valueOf(bitmap));
}

另外请帮助我如何从录制的视频意图中获取缩略图

Intent takeVideo = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
startActivityForResult(takeVideo, REQUEST_VIDEO_CAPTURE);

Answer 1

经过一些研究，我注意到 file path 不应该是 uri

你应该有这样的东西

final String noturipath = getRealPathFromUri();

Bitmap bitmap = ThumbnailUtils.createVideoThumbnail(noturipath, MediaStore.Video.Thumbnails.MICRO_KIND);

然后创建一个方法

    public string getRealPathFromUri (final Uri content)
    {
 // get intent from activity and added it here

    Uri uri;
    String stringUri;
    stringUri = uri.toString();
    }
