按鈕blings同時點擊如果背景圖像被添加

Question

下面是按鈕：

<Button 
     android:id="@+id/button1" 
     android:layout_width="250dp" 
     android:layout_height="75dp" 
     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginBottom="39dp" 
     android:background="@drawable/sam_back" /> 

當selector屬性用於它不能被實現，因爲作爲android:background已用於背景圖像。請幫忙解決這個問題。
