如何在Android的视频视图中获取视频的总长度 [英] how to get total length of video in video view in android

问题描述

我有一个问题，我要为此在视频视图中运行的视频的总长度，我正在使用视频视图的getDuration方法，但是在将它与currentPosition进行比较时，它始终返回-1.实际上，我希望如果视频的当前位置等于视频的总长度，那么它应该从第0个位置开始，即开始.意思是说我想比较视频的当前位置和视频的总长度，我该怎么做?

I have a problem that I want to get total length of video which is running in Video View for this I am using getDuration Method of video view but it always returns -1 when I am comparing it with currentPosition. Actually I want that if video's currentposition is equals to the total length of the video then it should start from the 0th position means starting. Mean I want to say that I want to compare Video current position with the total length of the video, how can I do that?

提前谢谢.

代码:

videoPosition=VideoPositionFinding(IDValue,video.getDuration());
    video.seekTo(videoPosition);
    if(video.getCurrentPosition()==video.getDuration()){
        videoPosition=0;
    }
     locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
     System.out.println("The Video Duration: "+video.getCurrentPosition());

     video.start();

推荐答案

要获取视频的总长度，请使用代码:

To get total length of video use code:

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener()  {
            @Override
            public void onPrepared(MediaPlayer mp) {                         
                long duration = videoView.getDuration();
            }
        });
