本文介绍了一个简单的Android应用示例，该应用使用VideoView组件实现基本的视频播放功能，并通过按钮控制播放、暂停和重新播放。代码展示了如何设置媒体控制器、加载视频路径以及响应用户点击事件。

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        huanchong();
        initVideoPath();

    }

    private void huanchong() {
        MediaController mc = new MediaController(MainActivity.this);//Video是我类名，是你当前的类

        videoView.setMediaController(mc);//设置VedioView与MediaController相关联

    }

    private void initVideoPath() {
       // File file = new File("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4");
        videoView.setVideoPath("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4");
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.play:
                if (!videoView.isPlaying()) {
                    videoView.start();
                }
                break;
            case R.id.pause:
                if (videoView.isPlaying()) {
                    videoView.pause();
                }
                break;
            case R.id.replay:
                if (videoView.isPlaying()) {
                    videoView.resume();

                break;
        }

    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (videoView != null) {
            videoView.suspend();
        }
    }
}

代码很简单，一看就可以明白的哦，希望大家有好的框架或者好的意见，一起相互学习哦
