我想从互联网路径的videoview获取以MB为单位的视频大小 [英] I want to get the video size in MB from videoview from internet path

问题描述

我正在尝试获取视频文件的大小并将其显示在布局中，然后再开始播放视频.

I'm trying to get the video file size and display it in the layout before starting the video.

我尝试了很多事情，但是没用

I have tried many thing but it wont work

video_player_view = (VideoView) findViewById(R.id.videoView2);
    media_Controller = new MediaController(this);
    dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics(dm);
    int height = dm.heightPixels;
    int width = dm.widthPixels;
    try {
        video_player_view.setMinimumWidth(width);
        video_player_view.setMinimumHeight(height);
    } catch (Exception e) {}
    video_player_view.setMediaController(media_Controller);
    video_player_view.setVideoPath(path);
    video_player_view.start();


    if (savedInstanceState != null) {
        video_player_view.seekTo(savedInstanceState.getInt("current_position"));
    }

    vidTitle = (TextView) findViewById(R.id.vidTitle);
    vidDesc = (TextView) findViewById(R.id.vidDesc);
    vidSize = (TextView) findViewById(R.id.vidSize);
    vidDur = (TextView) findViewById(R.id.vidDur);
    vidDownload = (ImageButton) findViewById(R.id.vidDownload);
    vidFav = (CheckBox) findViewById(R.id.vidFav);
    vidTitle.setText(singleVideoInfo.title);
    vidDesc.setText(singleVideoInfo.description);
    video_player_view.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {
            progressBarCircularIndeterminate.setVisibility(View.GONE);
            int duration = video_player_view.getDuration() / 1000;
            int hours = duration / 3600;
            int minutes = (duration / 60) - (hours * 60);
            int seconds = duration - (hours * 3600) - (minutes * 60);
            String formatted = String.format("Duration: %d:%02d:%02d", hours, minutes, seconds);
            vidDur.setText(formatted);
            //vidSize.setText("???");


        }
    });

我希望在onPreparedlistener

我尝试过

URL myUrl = new URL("http://your_url.com/file.mp4");
URLConnection urlConnection = myUrl.openConnection(); 
urlConnection.connect();
int file_size = urlConnection.getContentLength();
    file_size = file_size /1024;

还有这个

URL myUrl = new URL("http://your_url.com/file.mp4");
myConnection = myUrl.openConnection();
List headersize = myConnection.getHeaderFields().get("content-Lenght");

什么都行不通 请帮助

推荐答案

我认为您的操作方式存在大小限制.尝试这种方式:

I think there's a size limit with the way you're doing it. Try this way:

final URL uri=new URL("http://your_url.com/file.mp4");
URLConnection connection;
try
{
   connection=uri.openConnection();
   connection.connect();
   final String contentLengthStr=ucon.getHeaderField("content-length");
   // do whatever
}

catch(final IOException exception)
{
}

编辑:我刚刚注意到您尝试过类似的操作，但是您拼写的长度错误，也许就是这样

edit: i just noticed you have tried something similar, but you spelt length incorrectly, maybe it's just that
