您正在以相同的座標繪製圖像。這就是爲什麼你看到最後一次繪製canvas.drawBitmap(位圖[定時器],10,20,空); – Raghunandan

請在文本正文中添加一個問題。你想要的是每個'bitmap []'條目要被順序繪製來模擬一個die roll? –

@Raghunandan:是的,我知道我正在使用同一個座標..但實際上這是我的要求。其實我有一個骰子的形象。我想像他們畫的那樣骰子在滾動。 –

try{ 
    Thread.sleep(1000);  
    canvas.drawBitmap(bitmap[timer], 10,20,null); 
    }catch(InterruptedException e){ 
} 

它符合你的答案嗎?
