如何在Android模擬器上運行的YouTube視頻

Question

我已在對此我取的ListView中的YouTube視頻列表中的程序，並已實施的onClick也

來源： - 我已經按照如何使用教程youtube gdata。使用YouTube和YouTube上的視頻填充列表視圖。源代碼可以在：

問題：

每當我點擊任何YouTube視頻項目行，讓特定的視頻在接下來的活動，但每當我點擊的視頻運行它不工作，每次只得到黑色的空間

GetYouTubeUserVideosTask.java

public class GetYouTubeUserVideosTask implements Runnable { 

public static final String LIBRARY = "Library"; 

private final Handler replyTo; 

private final String username; 


    public GetYouTubeUserVideosTask(Handler replyTo, String username) { 
this.replyTo = replyTo; 
this.username = username; 
    } 

    @Override 
    public void run() { 
try { 

    HttpClient client = new DefaultHttpClient(); 

    HttpUriRequest request = new HttpGet 
      ("http://gdata.youtube.com/feeds/api/users/ 
      GoogleDevelopers/uploads?v=2&alt=jsonc"); 
    // Get the response that YouTube sends back 
    HttpResponse response = client.execute(request); 
    // Convert this response into a readable string 
    String jsonString = StreamUtils.convertToString 
      (response.getEntity().getContent()); 
    // Create a JSON object that we can use from the String 
    JSONObject json = new JSONObject(jsonString); 

    // Get are search result items 
    JSONArray jsonArray = json.getJSONObject("data").getJSONArray("items"); 

    // Create a list to store are videos in 
    List<Video> videos = new ArrayList<Video>(); 

    for (int i = 0; i < jsonArray.length(); i++) { 
     JSONObject jsonObject = jsonArray.getJSONObject(i); 
     // The title of the video 
     String title = jsonObject.getString("title"); 
     // The url link back to YouTube, this checks if it has a mobile url 
     // if it doesnt it gets the standard url 
     String url; 
     try { 
    url = jsonObject.getJSONObject("player").getString("default"); 
     } catch (JSONException ignore) { 
    url = jsonObject.getJSONObject("player").getString("default"); 
     } 

    String thumbUrl = jsonObject.getJSONObject 
      ("thumbnail").getString("sqDefault"); 

     // Create the video object and add it to our list 
     videos.add(new Video(title, url, thumbUrl)); 
    } 
    // Create a library to hold our videos 
    Library lib = new Library(username, videos); 
    // Pack the Library into the bundle to send back to the Activity 
    Bundle data = new Bundle(); 
    data.putSerializable(LIBRARY, lib); 

    // Send the Bundle of data (our Library) back to the handler (our Activity) 
    Message msg = Message.obtain(); 
    msg.setData(data); 
    replyTo.sendMessage(msg); 

// We don't do any error catching, just nothing will happen if this task falls over 
} catch (ClientProtocolException e) { 
    Log.e("Feck", e); 
} catch (IOException e) { 
    Log.e("Feck", e); 
} catch (JSONException e) { 
    Log.e("Feck", e); 
} 
    } 

VideosListView.java

public class VideosListView extends 
    ListView implements android.widget.AdapterView.OnItemClickListener { 

private List<Video> videos; 
private VideoClickListener videoClickListener; 

public VideosListView(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs, defStyle); 
} 

public VideosListView(Context context, AttributeSet attrs) { 
    super(context, attrs); 
} 

public VideosListView(Context context) { 
    super(context); 
} 

public void setVideos(List<Video> videos){ 
    this.videos = videos; 
    VideosAdapter adapter = new VideosAdapter(getContext(), videos); 
    setAdapter(adapter); 
    // When the videos are set we also set an item click listener to the list 
    // this will callback to our custom list whenever an item it pressed 
    // it will tell us what position in the list is pressed 
    setOnItemClickListener(this); 
} 

// Calling this method sets a listener to the list 
// Whatever class is passed in will be notified when the list is pressed 
// (The class that is passed in just has to 'implement VideoClickListener' 
// meaning is has the methods available we want to call) 
public void setOnVideoClickListener(VideoClickListener l) { 
    videoClickListener = l; 
} 

@Override 
public void setAdapter(ListAdapter adapter) { 
    super.setAdapter(adapter); 
} 

// When we receive a notification that a list item was pressed 
// we check to see if a video listener has been set 

@Override 
public void onItemClick(AdapterView<?> adapter, View v, int position, long id) { 
    if(videoClickListener != null){ 
     videoClickListener.onVideoClicked(videos.get(position)); 
    } 
} 

VideoClickListener.java

public interface VideoClickListener { 

public void onVideoClicked(Video video); 

    } 

Answer 1

模擬器不會播放YouTube視頻，因爲具有不同不同格式的YouTube，仿真器只支持3GP的視頻，你可以測試它在移動它會工作得很好。

Answer 2

我試過這個代碼，並與此我可以觀看YouTube視頻。所以試試這段代碼並告訴我你的狀態。

public class MainActivity extends Activity { 
    /** Called when the activity is first created. */ 
    @ Override 


    public void onCreate (Bundle savedInstanceState) { 
     super. onCreate (savedInstanceState); 



     setContentView (R.layout.activity_main); 

     WebView web = (WebView) findViewById (R.id.webView1); 
     web. getSettings().setJavaScriptEnabled (true); 
     web. getSettings().setJavaScriptCanOpenWindowsAutomatically (false); 
     web. getSettings().setPluginsEnabled (true); 
     web. getSettings().setSupportMultipleWindows (false); 
     web. getSettings().setSupportZoom (false); 
     web. setVerticalScrollBarEnabled (false); 
     web. setHorizontalScrollBarEnabled (false); 


     web. loadUrl ("http://www.youtube.com/watch?v=Wg65ohhDldc"); 

     web. setWebViewClient (new WebViewClient() { 
      @ Override public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      if (url.startsWith("vnd.youtube")){ 

      startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url))); 

      return true; 
      } 
      else 
      { 
      return false; 
      } 
      } 
     }); 
    } 

}
