机器人，构造的MediaController（）是未定义

问题描述

我有一个Android应用程序，做工精细用片段，

I have an android app, working fine with fragments,

我需要从展示片段的视频，但为了做到这一点，我需要实例化的MediaController，

I need to show a video from a fragment, but in order to do this, I need to instantiate mediacontroller,

但我得到：

The constructor MediaController() is undefined

在这里我的code：

here my code:

package com.orchard.elasto.custom;

import com.egoclean.elasto.R;

import android.content.Context;
import android.content.res.Resources;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.util.TypedValue;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.MediaController;
import android.widget.TextView;
import android.widget.VideoView;


//public class VideoView {

public class VideoViewBox extends Fragment{

    // public MediaController mc;


    private MediaController mediaController = new MediaController(this);



    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {


        //return inflater.inflate(R.layout.video_view, container,false);

        View view = inflater.inflate(R.layout.video_view, container,false);


           VideoView mVideo = (VideoView) view.findViewById(R.id.video_viewer);;



        mediaController.setAnchorView(mVideo);

      //Set video link (mp4 format )
//        Uri video = Uri.parse("android.resource://com.egoclean.elasto/raw/shoulder");

        Uri video = Uri.parse("android.resource://" + getClass().getPackage().getName() + "/" + R.raw.video1);


        mVideo.setMediaController(mediaController);
        mVideo.setVideoURI(video);
        mVideo.start();






        return view;

    }

}

那么，
如何实例化我的媒体控制器？

so ,how to instantiate my media controller?

谢谢！

推荐答案

这样的事情，也许，

MediaController mediaController = new MediaController(getActivity().getApplicationContext());
