Question

我有我开发的这个应用程序，它在模拟器上运行良好，没有任何错误。但是当我尝试在手机上运行同样的测试时，应用程序崩溃说明filenotfoundexception。它说文件/res/drawable/divider_horizontal.9.png丢失了。但实际上，我从未通过我的代码引用该文件。我相信它的系统/ os文件不可用。我有一个自定义列表视图，我猜它是那里的分隔符... 有人可以建议这里有什么问题。我相信这是一个类似的问题在这里讨论..但我无法理解它

listview.xml布局文件

<?xml version="1.0" encoding="utf-8"?>

Answer 1

通货膨胀期间出现问题。 Inflating没有最好的错误报告/恢复，因此当它遇到问题时会抛出奇怪的神秘消息。我相信问题出在listview.xml中，问题很可能是你添加到其中一个元素的xml属性之一。第6行我认为是指第一个或第二个Button元素。当它进行编译时，似乎每个元素只有一行。我首先要删除程序运行时不需要的所有标记，例如gravity和layout_weight。

抱歉，我无法提供更具体的答案;当你遇到像这样的通胀错误时，这是一个在黑暗中探索直到你发现错误的问题。

至于为什么在手机而不是仿真器上发生这种情况，很可能只是两者之间的操作系统差异（操作系统版本，正在使用的UI，制造商所做的其他更改等）。在模拟器上进行测试可以让您了解程序在手机上的外观和运行方式，但不能保证。

感谢提供如此多的信息，它使故障排除变得更加容易;-)如果我的建议有效，或者您需要更多信息，请告诉我。

Answer 2

我尝试使用自己的资源文件，其扩展名类似于“/res/drawable/divider_horizontal.9.png”E.G. “.9.png”据说这种类型的文件用于Android，以便知道图像具有可以调整的特殊边界。我尝试使用这种类型的文件扩展名创建自己的按钮，我也遇到了错误。我没有“.9”扩展名替换了我的文件，我不再有任何问题。当您引用该文件时，您永远不应该拥有该扩展名。

Answer 3
