导致资源的Android自定义按钮状态选择器XML文件$ NotFoundException

Question

由于Resource $ NotFoundException的原因，我的活动会随机崩溃，并且总是由于我的自定义按钮的状态选择器文件之一。崩溃是完全随机的，我会多次浏览整个应用程序而没有崩溃，然后第n次进入Activity，然后它会抛出异常。

而在ConfirmActivity线40是一段代码：

setContentView(R.layout.confirm); 

这里是RES /抽拉/ btn_green.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 

    <item 
     android:state_enabled="false" 
     android:drawable="@drawable/green_large_btn_pressed" /> 
    <item 
     android:state_pressed="true" 
     android:state_enabled="true" 
     android:drawable="@drawable/green_large_btn_pressed" /> 
    <item 
     android:state_focused="true" 
     android:state_enabled="true" 
     android:drawable="@drawable/green_large_btn" /> 
    <item 
     android:state_enabled="true" 
     android:drawable="@drawable/green_large_btn" /> 
</selector> 

这在整个应用程序中发生异常，它总是我的一个按钮。同样的事情发生在我的btn_gray和btn_orange。

color_large_btn.png和color_large_btn_pressed.png都适用于所有颜色。

的Android版本：0​​目前上的Droid2运行Android 2.2 也恰好在摩托罗拉Blur的运行Android 2.1 似乎并没有发生在宏达电Evo运行Android 2.3

Answer 1

这个问题本质上是一个彻头彻尾的内存场景。在try-catch块中结束我的xml文件膨胀后，我能够通过这个最初的错误，无法加载文件/找到它们。由此产生的行为是图像的活动只是简单地丢失，直到最后引发实际的内存异常。

修复？找到并删除了大量泄漏，并缩小了几个图像文件的大小。
