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

标签： java android xml android-resources android-color

我正在尝试按照Android开发人员指南Color State List Resource | Android Developers在我的Android应用程序中实现颜色状态列表资源。因此，我在目录button_text.xml中创建了两个资源文件button_background.xml和res/color/，并分别在@color/button_text中的@color/button_background和activity_main.xml中引用它们。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"/>

在运行应用程序时，我在日志中收到Resources Not Found Exception，如下所示：

我试图清理并重建项目，但它没有用。另外，将xml files放在res/drawable/而不是res/color/中会显示相同的错误。请帮助解决问题。提前谢谢！

修改

以下是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>

所以，在这里。请阅读完整的答案。与android:background不同，Color State List属性不支持android:textColor。要使android:background属性正常工作，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>

注意使用android：drawable而不是android：color。 Android将使用颜色资源并使其成为可绘制的。要完成此操作，您需要将颜色资源添加到res / values / colors.xml文件中。

试试这会对你有所帮助 关注此

第1步： - ＆gt;在res / color /目录中创建一个button_text.xml。 

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item  android:state_enabled="true" android:state_pressed="false" android:color="@color/colorPrimary"/>
<item  android:state_enabled="false" android:color="@color/colorAccent"/>
<item  android:state_enabled="true" android:state_pressed="true" android:color="@color/colorPrimaryDark"/>
</selector>

第2步： - ＆gt;在res / drawble /目录中创建一个button_selector.xml。

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item  android:state_enabled="true" android:state_pressed="false" android:drawable="@drawable/disha"/>
<item  android:state_enabled="false" android:drawable="@drawable/back"/>
<item  android:state_enabled="true" android:state_pressed="true" android:drawable="@drawable/ic_edit_pen"/>
</selector>

第3步： - 现在按下按钮 

    <Button
    android:id="@+id/b1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColor="@color/button_text"
    android:background="@drawable/button_selector" />

答案 2 :(得分：0)

如果您看起来更好的堆栈跟踪异常，您应该找到：

 Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #4: <item> tag requires a 'drawable' attribute or child tag defining a drawable

您可以在此处找到解决方案： Error : <item> tag requires a 'drawable' attribute or child tag defining a drawable

答案 3 :(得分：-1)

首先，您必须将button_text.xml和button_background.xml转移到drawable目录。

然后设置如下：

android:textColor="@drawable/button_text"
android:background="@drawable/button_background"
