public void initView(){
videoView= (VideoView) findViewById(R.id.vv_video);
playVideo();

public void playVideo(){
//String file=Environment.getExternalStorageDirectory().getPath()+"/oppo.3gp";//oppo.3gp视频播放的名字
String uri = "android.resource://" + getPackageName() + "/" + R.raw.oppo;
videoView.setVideoURI(Uri.parse(uri));
MediaController mc = new MediaController(this);
//设置控制器 控制的是那一个videoview
