在这里我的代码播放你管视频使用Urls。这可能无法提供您的完整要求，但您可以使用它。

我VideoPlayActivity.class（活动）

import java.io.File; 

import android.annotation.SuppressLint; 
import android.app.Activity; 
import android.content.Context; 
import android.content.SharedPreferences.Editor; 
import android.media.MediaPlayer; 
import android.media.MediaPlayer.OnCompletionListener; 
import android.media.MediaPlayer.OnErrorListener; 
import android.os.Bundle; 
import android.view.Gravity; 
import android.view.View; 
import android.webkit.WebChromeClient; 
import android.webkit.WebView; 
import android.webkit.WebViewClient; 
import android.widget.FrameLayout; 
import android.widget.FrameLayout.LayoutParams; 
import android.widget.RelativeLayout; 
import android.widget.Toast; 
import android.widget.VideoView; 

@SuppressLint("SetJavaScriptEnabled") 
public class VideoPlayActivity extends Activity { 

    RelativeLayout a; 
    VideoView video; 
    WChromeClient chromeClient; 

    WebView mWebView; 

    WebViewClient wvClient; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     a = (RelativeLayout) findViewById(R.id.web); 
     chromeClient = new WChromeClient(); 
     wvClient = new WebViewClient(); 
     mWebView = (WebView) findViewById(R.id.webView1); 

     mWebView.setWebChromeClient(chromeClient); 
     mWebView.setWebViewClient(wvClient); 
     mWebView.getSettings().setJavaScriptEnabled(true); 
     mWebView.getSettings().setDomStorageEnabled(true); 

     mWebView.loadUrl("http://www.youtube.com/embed/"+"YCR7F6h3q2c"+"?autoplay=0"); 


    } 

    class WChromeClient extends WebChromeClient { 

     @Override 
     public void onShowCustomView(View view, CustomViewCallback callback) { 
      // TODO Auto-generated method stub 
      super.onShowCustomView(view, callback); 
      if (view instanceof FrameLayout) { 
       FrameLayout frame = (FrameLayout) view; 
       if (frame.getFocusedChild() instanceof VideoView) { 
        mWebView.setVisibility(View.GONE); 
        video = (VideoView) frame.getFocusedChild(); 
        FrameLayout.LayoutParams par = new FrameLayout.LayoutParams(
          LayoutParams.MATCH_PARENT, 
          LayoutParams.MATCH_PARENT); 
        par.gravity = Gravity.CENTER_HORIZONTAL; 
        video.setLayoutParams(par); 
        frame.removeView(video); 
        a.addView(video); 
        video.setOnCompletionListener(new OnCompletionListener() { 

         @Override 
         public void onCompletion(MediaPlayer mp) { 
          Toast.makeText(VideoPlayActivity.this, 
            "Video complited", Toast.LENGTH_LONG) 
            .show(); 

         } 
        }); 

        video.setOnErrorListener(new OnErrorListener() { 

         @Override 
         public boolean onError(MediaPlayer mp, int what, 
           int extra) { 
          Toast.makeText(VideoPlayActivity.this, 
            "Encountered some error", Toast.LENGTH_LONG) 
            .show(); 
          return true; 
         } 
        }); 
        video.start(); 
       } 

      } 

     } 
    } 

    @Override 
    protected void onDestroy() { 
     android.os.Process.killProcess(android.os.Process.myPid()); 
     Editor editor = getSharedPreferences("clear_cache", 
       Context.MODE_PRIVATE).edit(); 
     editor.clear(); 
     editor.commit(); 
     trimCache(this); 
     super.onDestroy(); 
    } 

    public static void trimCache(Context context) { 
     try { 
      File dir = context.getCacheDir(); 
      if (dir != null && dir.isDirectory()) { 
       deleteDir(dir); 

      } 
     } catch (Exception e) { 
      // TODO: handle exception 
     } 
    } 

    public static boolean deleteDir(File dir) { 
     if (dir != null && dir.isDirectory()) { 
      String[] children = dir.list(); 
      for (int i = 0; i < children.length; i++) { 
       boolean success = deleteDir(new File(dir, children[i])); 
       if (!success) { 
        return false; 
       } 
      } 
     } 

     // <uses-permission 
     // android:name="android.permission.CLEAR_APP_CACHE"></uses-permission> 
     // The directory is now empty so delete it 

     return dir.delete(); 
    } 

} 

activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/web"> 

    <WebView 
     android:id="@+id/webView1" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 

     /> 

</RelativeLayout> 

清单文件

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.webviewchromclient" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="8" 
     android:targetSdkVersion="15" /> 
    <uses-permission android:name="android.permission.INTERNET"/> 

    <application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" android:hardwareAccelerated="true"> 
     <activity 
      android:name=".VideoPlayActivity" 
      > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 

    </application> 

</manifest>
