在動畫中使用5-6個線程是一個好主意嗎？

Question

我使用5-6個線程一次顯示一個動畫。我正在使用翻譯動畫以及框架動畫。這是一個好主意嗎？什麼是最好的方式來做到這一點？我的代碼如下。

Handler handler1 = new Handler();   
handler1.postDelayed(new Runnable() { 
    public void run() { 
    Animation animation = new TranslateAnimation(0 ,0 ,0 ,100); 
    animation.setDuration(800); 
    ImageView rimg2 = (ImageView) findViewById(R.id.rainfall); 
    animation.setRepeatCount(-1); 
    rimg2.startAnimation(animation); 

    Animation animation1 = new TranslateAnimation(-290, 290,0, -150); 
    animation1.setDuration(35000); 
    ImageView rimg = (ImageView) findViewById(R.id.cloud1); 
    rimg.setVisibility(View.VISIBLE); 
    animation1.setRepeatCount(-1); 
    rimg.startAnimation(animation1); 
    } 
},0); 

Handler handler2 = new Handler(); 
handler2.postDelayed(new Runnable() { 
    public void run() { 
    Animation animation = new TranslateAnimation(0 ,0 ,0 ,100); 
    animation.setDuration(800); 
    ImageView rimg3 = (ImageView) findViewById(R.id.drops); 
    animation.setRepeatCount(-1); 
    rimg3.startAnimation(animation); 
    rimg3.setVisibility(View.VISIBLE); 
    } 
},1000); 

Handler handler3 = new Handler(); 
handler3.postDelayed(new Runnable() { 
    public void run() { 
    Animation animation = new TranslateAnimation(0 ,0 ,-250 ,10); 
    animation.setDuration(800); 
    ImageView rimg2 = (ImageView) findViewById(R.id.rainfall1); 
    animation.setRepeatCount(-1); 
    rimg2.startAnimation(animation); 
    rimg2.setVisibility(View.VISIBLE); 
    } 
},5000); 

Handler handler4 = new Handler(); 
handler4.postDelayed(new Runnable() { 
    public void run() { 
    Animation animation = new TranslateAnimation(0 ,0 ,-150 ,10); 
    animation.setDuration(800); 
    ImageView rimg3 = (ImageView) findViewById(R.id.drops1); 
    animation.setRepeatCount(-1); 
    rimg3.startAnimation(animation); 
    rimg3.setVisibility(View.VISIBLE); 
    } 
},10000); 

Handler handler5 = new Handler(); 
handler5.postDelayed(new Runnable() { 
    public void run() { 
    Animation animation1 = new TranslateAnimation(-290, 290,0, -150); 
    animation1.setDuration(35000); 
    ImageView rimg = (ImageView) findViewById(R.id.cloud2); 
    rimg.setVisibility(View.VISIBLE); 
    animation1.setRepeatCount(-1); 
    rimg.startAnimation(animation1); 
    } 
},15000);

除非有您的代碼示例中未顯示的原因，你並不需要張貼的Runnable運行這些動畫。您可以從主UI線程啓動動畫。欲瞭解更多詳情，看看這裏的文檔：

，如果你想錯開動畫的開始時間，您還可以設置開始偏移。

如果你想要做的事當動畫結束時，你可以用你的建議Animation.setAnimationListener
