本文介绍了一个简单的Android应用，该应用使用VideoView组件从设备存储和assets资源中加载并播放视频。文章展示了如何通过复制文件到外部存储并在VideoView中设置路径来实现视频播放。

    public class MainActivity extends Activity {

        private VideoView video;
        private String path="";

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            video = (VideoView) findViewById(R.id.videoview);
//        assets读取视频文件
            if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
            {
                File file = Environment.getExternalStorageDirectory();
                File file2 = new File(file.getAbsoluteFile()+"/video.mp4");
                path = file2.getAbsolutePath();
                try {
                    InputStream is = getAssets().open("video1.mp4");
                    FileOutputStream fo = new FileOutputStream(file2);
                    byte[] b=new byte[1024];
                    while (true) {
                        int m = is.read(b);
                        if(m==-1)
                            break;
                        fo.write(b, 0, m);
                    }
                    fo.flush();
                    is.close(); fo.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

//        设置视频文件的路径
            video.setVideoPath(path);


//        raw读取视频播放
//     video.setVideoPath("android.resource://"+getPackageName()+"/"+R.raw.video1);
            findViewById(R.id.start).setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    MediaController media=new MediaController(MainActivity.this);
                    video.setMediaController(media);
                    media.setAnchorView(video);
                    video.start();
                }
            });
        }
    }
