如何複製surfaceview爲位圖

Question

我想surfaceview複製到的位圖，但只是讓黑色（FF000000）

//this.surView is my SurfaceView 
    Bitmap bitmap =Bitmap.createBitmap(this.surView.getWidth(), this.surView.getHeight(),  Bitmap.Config.RGB_565); 
     //this.can is my canvas 
    this.can = this.surHolder.lockCanvas(new Rect(0,0,this.surView.getWidth(), this.surView.getHeight())); 
    this.can.setBitmap(bitmap); 
    this.surView.draw(this.can); 
    this.surHolder.unlockCanvasAndPost(can); 
     // bitmap = Bitmap.createBitmap(bitmap); 
        //copy bitmap from (srcx,srcy) to (x,y) 
     bitmap = Bitmap.createBitmap(bitmap, srcx, srcy, cx, cy); 

     this.ondrawImage(bitmap, x, y);

使用surfaceview.getDrawingCache()將得到位圖。
