我需要在我的視圖中調用MediaPlayer

Question

是否有任何可能的方式在延伸視圖的類中調用MediaPlayer？

我已經讓我的Activity類成功地運作了mediaplayer。

如果這是不可能的，有沒有一種方法可以調用方法，從我的View類開始在我的Activity類中傳輸音頻流？

Android。

public class RealPlayView extends View { 
// call objects 
private Background background; 
private Grid grid; 
private Box[] box = new Box[30]; 
private Paint[] paint = new Paint[30]; 
private UpdateHandler updatehandler; 
private Handler invalidatehandler; 
private ColorFilter filter; 

// sound variables 
private RealPlayActivity realplayactivity; 

// variables 
public int lineNum = 0; 
public int boxValue = 3; 
public int gameSpeed = 250; 
public int controlMove = 1; 
public int controlSet = 1; 
public boolean goRight; 

// other variables regarding plain function 
public int setX1 = 100; 
public int setX2 = 100; 
public int setX3 = 100; 
public int endGame = 0; 

// variables regarding to checker 
public int X1; 
public int X2; 
public int X3; 
public int X4; 
public int X5; 
public int X6; 
public int X4D; 
public int X5D; 
public int X6D; 

public RealPlayView(Context context) { 
    super(context); 

    // call objects 
    background = new Background(context, R.drawable.background); 
    grid = new Grid(context, R.drawable.grid); 
    updatehandler = new UpdateHandler(); 
    invalidatehandler = new Handler(); 
    filter = new PorterDuffColorFilter(0xffffcc33, PorterDuff.Mode.SRC_ATOP); 
    }

嘗試與context

MediaPlayer mp_xmPlayer2 = MediaPlayer.create(context, R.raw.error); 
mp_xmPlayer2.start();
