Question

这是我的代码。

public class MainActivity extends Activity {
    ListView list;
    public ArrayList<String> videoList;
    public CustomListAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        list =(ListView)findViewById(R.id.list);
        videoList = new ArrayList<String>();
        videoList.add("https://www.youtube.com/watch?v=Zgfi7wnGZlE");
        videoList.add("https://www.youtube.com/watch?v=Zgfi7wnGZlE");
        videoList.add("https://www.youtube.com/watch?v=Zgfi7wnGZlE");
        videoList.add("http://www.youtube.com/watch?v=DdlWPL53PvQ#sthash.fW5EtDFb.dpuf");
        Log.d("size of videoList:",""+ videoList.size());
        adapter = new CustomListAdapter(MainActivity.this, videoList);
        list.setAdapter(adapter);
    }
    public class CustomListAdapter extends BaseAdapter {
        private Activity activity;
        private LayoutInflater inflater;
        private ArrayList<String> videoList;

        public CustomListAdapter(Activity activity, ArrayList<String> videoList) {
            this.activity = activity;
            this.videoList = videoList;
        }

        @Override
        public int getCount() {
            return videoList.size();
        }

        @Override
        public Object getItem(int location) {
            return videoList.get(location);
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            if (inflater == null)
                inflater = (LayoutInflater) activity
                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            if (convertView == null)
                convertView = inflater.inflate(R.layout.list_row, null);

              VideoView video = (VideoView)convertView.findViewById(R.id.video_view);
             video.setVideoPath(videoList.get(position));
             video.start();
             return convertView;
        }

    }    
}

activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"
        android:listSelector="@drawable/list_row_selector" />

</RelativeLayout>

list_raw.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/list_row_selector"
    android:padding="8dp" >

    <!-- Thumbnail Image -->


    <VideoView
        android:id="@+id/video_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center" />


</RelativeLayout>

我无法获取视频，并且logcat中没有任何错误显示然后是什么问题？我在清单中添加了互联网许可，是否需要任何许可或其他任何设置？

Answer 1

我认为我们不应该直接在列表中放置视频视图，因为列表中的每个视图都被重绘或无效很多次，如果用户正在播放和观看任何视频，并且他不小心将其滚出屏幕， Android操作系统将释放该内存，因此将再次从Start播放视频。 会一次又一次地调用Video.start（）

最佳解决方案是提供任何视频帧的缩略图。 用图片视图替换视频视图，然后点击它打开一个新视频，放置视频视图并播放。

Answer 2

尝试设置VideoURI代替VideoPath，然后再次检查，

VideoView video = (VideoView)convertView.findViewById(R.id.video_view);
MediaController mediaController = new MediaController(this); 
mediaController.setAnchorView(video);
video.setMediaController(mediaController);
video.setVideoURI(Uri.parse(videoList.get(position)));
video.start();

更新：如果您计划仅使用YouTube上的视频，那么最好的方法是使用官方YouTube API。点击这里，
