VideoView

在main.xml中加入：

<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android" 
        android:layout_width="fill_parent" android:layout_height="fill_parent"> 
        <VideoView android:id="@+id/videoView" android:layout_width="fill_parent" 
            android:layout_height="fill_parent" android:layout_x="10px" 
            android:layout_y="10px" /> 
    </AbsoluteLayout>

在類中，加入以下程式碼

super.onCreate(savedInstanceState); 
        requestWindowFeature(Window.FEATURE_NO_TITLE); 
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);//設定成全屏模式 
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//強制為橫屏 
        setContentView(R.layout.main); 
       videoView = (VideoView) findViewById(R.id.videoView); 
//       videoView.setVideoPath("/sdcard/xyx.3gp"); 
       videoView.setVideoURI(Uri.parse("/sdcard/beijinghuanyingni.mp4")); 
       MediaController mediaController = new MediaController(this); 
       videoView.setMediaController(mediaController); 
       videoView.start(); 
       //videoView.requestFocus();

首先我使用的是全屏，強制橫屏播放視訊。.setVideoURI是設定視訊的路徑，這裡我用的是sdcard上的視訊，如果用http的，則需寫完整路徑。最重要的一點，我看網上有用videoView.requestFocus();來載入視屏播放，這裡我沒有能播放成功，改用了videoView.start();來播放。 
這種方式是使用Android自帶的按鈕，無需自定義暫停、播放等按鈕控制元件。
