我的card片有录像。 我愿在我的图像学文中对这一视频进行预览。 请让我知道如何在安乐斯这样做。 感谢你的帮助和时间。
如果您使用第8级及以上。 你们可以制作这样的录像:
String videoFile = "/sdcard/blonde.mp4";
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail(videoFile,
MediaStore.Images.Thumbnails.MINI_KIND);
现在请在<代码>上显示。 图表:
ImageView imageView = (ImageView) findViewById(R.id.my_image_view);
imageView.setImageBitmap(thumbnail);
或者,作为背景,你可以将其带至<代码>VideoView上,以便在录像开始之前作为第一个视频框架显示:
VideoView video = (VideoView) findViewById(R.id.my_video_view);
BitmapDrawable bitmapDrawable = new BitmapDrawable(thumbnail);
video.setBackgroundDrawable(bitmapDrawable);
这个例子用于blonde.mp4文档:
String videoFile = "/sdcard/blonde.mp4";
Bitmap thumbnail = ThumbnailUtils.createVideoThumbnail(videoFile, MediaStore.Images.Thumbnails.MINI_KIND);
