• 能够被高度扩展和定制，以适用不同的场景。

二、使用

1. 添加依赖

implementation 'com.google.android.exoplayer:exoplayer:2.11.0'

2. 清单文件中申请权限及 application 设置

3. 布局文件

4. MainActivity.java

public class MainActivity extends AppCompatActivity {
    private PlayerView mPlayerView;

    private SimpleExoPlayer player;

    private boolean playWhenReady;

    private int currentWindow;

    private long playbackPosition;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        init();
    }

    private void init() {
       mPlayerView = findViewById(R.id.video_view);
       initializePlayer();
    }

    private void initializePlayer() {
        player = new SimpleExoPlayer.Builder(this).build();

        player.setPlayWhenReady(playWhenReady);
        player.seekTo(currentWindow, playbackPosition);
        Uri playUri = Uri.parse("https://stream7.iqilu.com/10339/upload_transcode/202002/18/20200218114723HDu3hhxqIT.mp4");
        MediaSource mediaSource = buildMediaSource(playUri);
        player.prepare(mediaSource, true, false);

        mPlayerView.setPlayer(player);
    }

    private MediaSource buildMediaSource(Uri uri) {
        DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(this, "com.example.exoplayerdemo");
        MediaSource videoSource = new ExtractorMediaSource.Factory(dataSourceFactory).createMediaSource(uri);
        return videoSource;
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        player.release();
    }
}
