的Android java.lang.StackOverflowError的TransitionDrawable

我得到一个计算器错误，当我在TextView的应用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"); 
    } 

}

}

我几乎可以肯定你在一个循环中调用applyAnimationTransitionBackground()，例如onDrawFrame()的一个Renderer（我说这只是因为我看到GL ES的使用，但它可能是某种或另一种事情的动画）。

我这么认为是因为你设置了背景view。在view的第一个背景是两种颜色之间的转换可绘制 - 我们称之为T(C1, C2)。对于每一个连续的呼叫中，view的背景设置为之间的过渡可绘制：

的view当前背景和
一些颜色绘制

在效果：

后第二次电话，view背景设置为转换T(T(C1, C2), C3)。
第三次通话后，view后台设置为转换T(T(T(C1, C2), C3), C4)。
等等...

实际上，即使经过100个电话，你有一个背景绘制设置为100个过渡可绘制一个大规模组合。您可以想象在对您的方法进行1000或10000次调用后会发生什么。由于转换可绘制只是将绘图委托给它们的组件绘图，所以最终会出现堆栈溢出。

最简单的方法来检查是否正是这种情况是将行Logger.info("call");放在applyAnimationTransitionBackground()的开头。如果在日志（LogCat）中看到很多call消息，则情况就是如此。

要解决这个问题，你只需要从这种组合drawable的模式中辞职。例如，您可以保存用于转场的最后一个颜色值及其开始时间。然后，当您需要在当前颜色和新颜色之间创建过渡时，可以使用保存的开始时间和颜色来内插背景的当前颜色。然后，您可以简单地创建一个新的转换可绘制 - 在当前颜色和新颜色之间。
