製作動畫從imageview切換圖像（Android）

Question

我是一個Android的新手，我正在製作一個老虎機遊戲，但無法弄清楚如何使用老虎機的動畫。現在我正在嘗試使用3個不同png文件進行切換的滾動動畫，並且logcat提供了有關跳幀的一些信息。它只是不改變圖像。對不起我的英語不好。

方法的代碼：

public void animation(){ 
     imageView1.setImageResource(R.drawable.slot1); 
     imageView2.setImageResource(R.drawable.slot2); 
     imageView3.setImageResource(R.drawable.slot3); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot2); 
     imageView2.setImageResource(R.drawable.slot3); 
     imageView3.setImageResource(R.drawable.slot1); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot3); 
     imageView2.setImageResource(R.drawable.slot1); 
     imageView3.setImageResource(R.drawable.slot2); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot1); 
     imageView2.setImageResource(R.drawable.slot2); 
     imageView3.setImageResource(R.drawable.slot3); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot2); 
     imageView2.setImageResource(R.drawable.slot3); 
     imageView3.setImageResource(R.drawable.slot1); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot3); 
     imageView2.setImageResource(R.drawable.slot1); 
     imageView3.setImageResource(R.drawable.slot2); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot1); 
     imageView2.setImageResource(R.drawable.slot2); 
     imageView3.setImageResource(R.drawable.slot3); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot2); 
     imageView2.setImageResource(R.drawable.slot3); 
     imageView3.setImageResource(R.drawable.slot1); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot3); 
     imageView2.setImageResource(R.drawable.slot1); 
     imageView3.setImageResource(R.drawable.slot2); 
     android.os.SystemClock.sleep(70); 
     imageView1.setImageResource(R.drawable.slot1); 
     imageView2.setImageResource(R.drawable.slot2); 
     imageView3.setImageResource(R.drawable.slot3); 
     android.os.SystemClock.sleep(70); 
    } 

logcat的：

05-08 17：06：53.230：I /指導（943）：跳過74幀！ 應用程序可能在其主線程上做了太多工作。

您正在主UI線程上調用睡眠，您需要從單獨的線程或AsyncTask運行此代碼。
