的Android java.lang.StackOverflowError的TransitionDrawable

我得到一個計算器錯誤，當我在TextView的應用TransitionDrawable：的Android java.lang.StackOverflowError的TransitionDrawable

private static void applyAnimationTransitionBackground(String descriptorValue, final Resources resources, View view){ 
Drawable currentBackground; 
TransitionDrawable td; 

if (view!=null){ 

    //Get current background or transparent color 
    currentBackground = view.getBackground(); 
    if (currentBackground==null){ 
     currentBackground = new ColorDrawable(android.R.color.transparent); 
    } 

    //Create transition depend on trend 
    if (descriptorValue.equals("1")){ 
     td= new TransitionDrawable (new Drawable []{currentBackground, new ColorDrawable(resources.getColor(R.color.positive_animation))}); 
    }else if (descriptorValue.equals("2")){ 
     td= new TransitionDrawable (new Drawable []{currentBackground, new ColorDrawable(resources.getColor(R.color.neutral_animation))}); 
    }else{ 
     td= new TransitionDrawable (new Drawable []{currentBackground, new ColorDrawable(resources.getColor(R.color.negative_animation))}); 
    } 

    //Apply animation 
    if (td!=null){ 
     view.setBackgroundDrawable(td); 
     td.startTransition(500); 
     //td.reverseTransition(500);    
    }else{ 
     Logger.error("applyAnimationTransitionBackground: TransitionDrawable is NULL"); 
    } 

}

}

我幾乎可以肯定你在一個循環中調用applyAnimationTransitionBackground()，例如onDrawFrame()的一個Renderer（我說這只是因爲我看到GL ES的使用，但它可能是某種或另一種事情的動畫）。

我這麼認爲是因爲你設置了背景view。在view的第一個背景是兩種顏色之間的轉換可繪製 - 我們稱之爲T(C1, C2)。對於每一個連續的呼叫中，view的背景設置爲之間的過渡可繪製：

的view當前背景和
一些顏色繪製

在效果：

後第二次電話，view背景設置爲轉換T(T(C1, C2), C3)。
第三次通話後，view後臺設置爲轉換T(T(T(C1, C2), C3), C4)。
等等...

實際上，即使經過100個電話，你有一個背景繪製設置爲100個過渡可繪製一個大規模組合。您可以想象在對您的方法進行1000或10000次調用後會發生什麼。由於轉換可繪製只是將繪圖委託給它們的組件繪圖，所以最終會出現堆棧溢出。

最簡單的方法來檢查是否正是這種情況是將行Logger.info("call");放在applyAnimationTransitionBackground()的開頭。如果在日誌（LogCat）中看到很多call消息，則情況就是如此。

要解決這個問題，你只需要從這種組合drawable的模式中辭職。例如，您可以保存用於轉場的最後一個顏色值及其開始時間。然後，當您需要在當前顏色和新顏色之間創建過渡時，可以使用保存的開始時間和顏色來內插背景的當前顏色。然後，您可以簡單地創建一個新的轉換可繪製 - 在當前顏色和新顏色之間。
