您好我在从网址播放视频时遇到问题。我正在使用片段,每当我运行我的代码时,我都会收到此错误:
错误:(32,34)错误:没有为MediaController找到合适的构造函数(MainFragment) 构造函数MediaController.MediaController(Context)不适用 (实际参数MainFragment无法通过方法调用转换转换为Context) 构造函数MediaController.MediaController(Context,boolean)不适用 (实际和正式的参数列表长度不同) 构造函数MediaController.MediaController(Context,AttributeSet)不适用 (实际和正式的参数列表长度不同)
这是我的代码:
public class MainFragment extends Fragment {
private static final String Video_url = "https://dl.dropboxusercontent.com/u/102136471/20151113_223245.mp4";
public MainFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
VideoView view = (VideoView) getView().findViewById(R.id.videoView);
Uri video = Uri.parse(Video_url);
view.setMediaController( new MediaController(this));
view.setVideoURI(video);
view.start();
view.requestFocus();
return inflater.inflate(R.layout.fragment_main, container, false);
}
我不确定这是否是在片段内打开视频视图的正确方法?
答案 0 :(得分:2)
做
view.setMediaController(new MediaController(getActivity()));
使用getActivity()
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v=inflater.inflate(R.layout.fragment_main, container, false);
// Inflate the layout for this fragment
VideoView view = (VideoView) v.findViewById(R.id.videoView);
Uri video = Uri.parse(Video_url);
view.setMediaController(new MediaController(getActivity()));
view.setVideoURI(video);
view.start();
view.requestFocus();
return v;
}
