使用視頻視圖(VideoView)類顯示從YouTube下載的視頻

視頻視圖(VideoView)類可以用來顯示從各種來源, 如資源(resources)或內容提供商, 載入的視頻文件.

下面的例子顯示了如何使用視頻視圖(VideoView)類顯示從YouTube載入的視頻.



main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   >
<TextView 
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:text="@string/hello"
   />
<VideoView
   android:id="@+id/video"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   />
</LinearLayout>

AndroidVideoView.java

package com.AndroidVideoView;

import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;

public class AndroidVideoView extends Activity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
      
       VideoView videoView = (VideoView)findViewById(R.id.video);
      
       String src = "rtsp://v2.cache2.c.youtube.com/CjYLENy73wIaLQm3JbT_9HqWohMYESARFEIJbXYtZ29vZ2xlSARSBXdhdGNoYIvJo6nmx9DvSww=/0/0/0/video.3gp";
       videoView.setVideoURI(Uri.parse(src));
       videoView.setMediaController(new MediaController(this));
       videoView.requestFocus();
       videoView.start();
   }
}

注意：它不能在Android模擬器顯示, 需要運行在真的Android機.
