Question

我在imageview和videoview中显示图像和视频，但问题出在视频时播放onpreparedlistener但是当视频完成oncompletion listener时没有调用当视频观看完成后，我将i增加为下一个视频或图像

它也给我这样的logcat错误，但视频正在播放

无论哪种方式，上面引用的错误都是MEDIA_ERROR_UNKNOWN。如果此视频是针对此应用制作的，我会确保它已针对Android进行了正确编码。还要确保明确定义其端点。

http://developer.android.com/reference/android/media/MediaPlayer.html#MEDIA_ERROR_UNKNOWN

这是一种解决方法，但可能适用于您的情况：

@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
    if(what == MediaPlayer.MEDIA_ERROR_UNKNOWN) 
        //ERROR UNKNOWN - COULD BE IMPROPERLY FORMATTED VIDEO {
        //MOVE ON TO NEXT VIDEO
        //DO LOGGING
    }
}

videoview oncompletionlistener没有在android中调用？
