老師，我在繪制盤塊背景的時候，模擬器上面不能顯示背景
/**
* 設(shè)置背景圖
*/
private Bitmap mBgBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.bg);
/**
*繪制背景
*/
private void drawBg() {
? ?mCanvas.drawColor(0xffffffff);
? ?mCanvas.drawBitmap(mBgBitmap,null,new RectF(mPadding/2,mPadding/2,getMeasuredWidth()-mPadding/2,getMeasuredHeight()-mPadding/2),null);
}
