MediaPlayer 類可用於控制音訊/視訊檔案和流的播放。

MediaPlayer 物件的建立可以有三種型別：

1. 來自本地資源的媒體

   MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.resource);
   mediaPlayer.start(); // no need to call prepare(); create() does that for you
   

2. 從本地 URI（從 ContentResolver 獲取）

   Uri myUri = ....; // initialize Uri here
   MediaPlayer mediaPlayer = new MediaPlayer();
   mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
   mediaPlayer.setDataSource(getApplicationContext(), myUri);
   mediaPlayer.prepare();
   mediaPlayer.start();
   

3. 來自外部 URL

   String url = "http://........"; // your URL here
   MediaPlayer mediaPlayer = new MediaPlayer();
   mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
   mediaPlayer.setDataSource(url);
   mediaPlayer.prepare(); // might take long! (for buffering, etc)
   mediaPlayer.start();
