Android的VideoView - 如何按顺序播放视频 [英] Android VideoView - How to play videos in sequence

问题描述

我想开发一个videoview扮演多个视频Android应用程序。当一个完成后，第二个有启动等

I'm trying to develop an android application that plays more than one video in one videoview. When one is finished, the second has to start and so on.

我的视频都存储在项目的原始文件夹，
得到他们的文件名我做的：

My videos are stored in the raw folder of the project, to get their filenames i do:

Field[] fields = R.raw.class.getFields();

        final List<String> videoNames = new ArrayList<String>() ;

        for(Field field: fields){
            videoNames.add(field.getName());
        }

然后我设定的第一个路径到我的视频查看

then i set the first one's path to my video view

 videoUri = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" 
                            + videoNames.get(0));

myVideoView.setVideoURI(videoUri);

玩别人

    myVideoView.setOnCompletionListener(new   MediaPlayer.OnCompletionListener() {

            @Override
            public void onCompletion(MediaPlayer mp) {


                 videoUri = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" 
                            + videoNames.get(VideoI));
                 myVideoView.setVideoURI(videoUri);

                 myVideoView.start();

                 if(VideoI==videoNames.size()-1)
                 {
                     VideoI=0;
                 }
                 else{
                     VideoI++;
                 }
            }
        });

但是...

每当我尝试在真实设备此code的时候，我得到了同样的错误
不能播放视频的时候，第一视频完成...

every time that i try this code in real device, i get the same error "can't play video" when the first video is finished...

所有的视频​​都记录了，我使用了相同的设备.mp4档案开发...

all the videos are .mp4 file recorded with the same device that i use for develop...

什么想法？或者其他的方式来按顺序播放更多的视频？
我找了一个解决方案，但到处都是我无法找到它。

any ideas? or other ways to play more videos in sequence? I looked for a solution everywhere but i couldn't find it..

修改

做到了！确定..错误是如此愚蠢的..谢谢大家了有用的答案。

DID IT!! ok.. the error was so silly.. thank you all for the helpful answers.

错误是在路径我一直在寻找（这些不是你想找的路径CIT）。

the error was in the path i was looking for ("these are not the paths your looking for" cit.)

为我写的，这些视频都存储在文件夹中的原始..
我使用

as i wrote, the videos are stored in raw folder.. i was using

 videoUri = Uri.parse("android.resource://" + MainActivity.ctx.getPackageName() + "/
                                    + videoNames.get(VideoI));

添加原料的文件夹路径

adding raw folder in path

videoUri = Uri.parse("android.resource://" + MainActivity.ctx.getPackageName() + "/raw/" 
                                    + videoNames.get(VideoI));

它最后的工作。至于我写的..这是一个愚蠢的。

it finally worked.. as i wrote.. it was a silly..

推荐答案

好吧你得到错误，因为你试图在CH375复位之前重新初始化videoview。更改了您的code这样的。

Well you are getting error because you are trying to initialize videoview again before reseting it. Make a change to your code like this.

myVideoView.setOnCompletionListener(new   MediaPlayer.OnCompletionListener() {

        @Override
        public void onCompletion(MediaPlayer mp) {

            startOtherVid();
        }
});

现在进行方法 startOtherVid（）和释放previous相继在这里初始化videoview。

Now make method startOtherVid() and initialize videoview here after releasing the previous one.

private void startOtherVid(){
  myVideoView.stopPlayback();
  videoUri = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" 
                        + videoNames.get(VideoI));
  myVideoView.setVideoURI(videoUri);

  myVideoView.start();
  .... 
   .....
}

此方式，您将释放一个videoview对象并重新创建。会有很短的时间来加载，但你可以直观地处理它。

This way you will release one videoview object and create again. There will be a short time to load, but you can handle it visually.

修改

您还可以释放MediaPlayer对象和解决您的问题。

You can also release mediaplayer object and solve your problem.

public void onCompletion(MediaPlayer mp) {

try {
    mp.reset();
    videoUri = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" 
                        + videoNames.get(VideoI));
    myVideoView.setVideoURI(videoUri);

    myVideoView.start();
}
catch(Exception e){e.printstacktrace();}
});

干杯。）
