onClick保持停止

Question

public class MandarinPage extends AppCompatActivity {
Button b01,b02,b03;
VideoView Vv01;
MediaController mediaC;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_mandarin_page);
    b01=(Button)findViewById(R.id.button01);
    b02=(Button)findViewById(R.id.button02);
    b03=(Button)findViewById(R.id.button03);

    Vv01=(VideoView)findViewById(R.id.videoView);
}

public void viedeplay(View v){
    String videopath = "android.resource://a0.besta_e_learning/"+R.raw.sample_video;
    Uri uri = Uri.parse(videopath); //URI stand for Uniform Resource Identifier
    Vv01.setVideoURI(uri);
    Vv01.setMediaController(mediaC);
    mediaC.setAnchorView(Vv01);
    Vv01.start();
}

当我点击播放按钮时，我的模拟器显示了这个。

Answer 1

我想这一行有错误。试着写视频的视频扩展部分

String videopath = 
"android.resource://a0.besta_e_learning/"+R.raw.sample_video.mp4;

或

 String videopath = 
 "android.resource://a0.besta_e_learning/"+R.raw.sample_video.3gp;
