android.content.res.Resources $ NotFoundException-/res/color/file.xml

Question

我试图实现颜色状态列表资源在我的Android应用程序，以下Android开发者指南颜色状态列表资源| Android开发人员。因此，我在目录中创建了两个资源文件button_text.xml和button_background.xml，res/color/并在@color/button_text和中@color/button_background分别引用了它们activity_main.xml。这是布局代码：

<Button
    android:id="@+id/myButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/app_name"
    android:layout_marginTop="150dp"
    android:layout_gravity="center"
    android:textColor="@color/button_text"
    android:background="@color/button_background"/>

在运行该应用程序时，我Resources Not Found Exception在日志中得到如下所示：

我曾尝试清理并重建项目，但没有成功。另外，把xml files在res/drawable/代替res/color/正显示出同样的error.Please帮助解决问题。提前致谢！

编辑：

这是button_text.xml文件代码：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="#000"
          android:state_pressed="true"/>
    <item android:color="#fff"
          android:state_activated="true"/>
</selector>

并且，button_background.xml文件代码：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="#fff"
          android:state_pressed="true"/>
    <item android:color="#000"
          android:state_activated="true"/>
</selector>

Answer 1

所以，就在这里。请阅读完整答案。该android:background属性不支持Color State Listdifferents android:textColor。要使android:background财产正常运转，您需要State List Drawables。因此，而不是res/color/在res/drawable/目录中创建文件。这是代码：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/white"
          android:state_pressed="true"/>
    <item android:drawable="@color/black"
          android:state_activated="true"/>
</selector>

请注意使用android：drawable而不是android：color。Android将使用颜色资源，并使用它来绘制图形。要完成此操作，您需要将颜色资源添加到res / values / colors.xml文件中。
