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

Question

我試圖在我的Android應用程序中實現顏色狀態列表資源，遵循Android開發人員指南Color State List Resource | Android Developers。因此，我在目錄res/color/中創建了兩個資源文件button_text.xml和​​，並在activity_main.xml中分別使用@color/button_text和@color/button_background來引用它們。這裏的佈局代碼：

<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"/> 

在運行應用程序，我得到在日誌中Resources Not Found Exception如下圖所示：

我試圖清理和重建項目，但它沒有工作。此外，將xml files置於res/drawable/而不是res/color/顯示相同的錯誤。請幫助解決該問題。提前致謝！

編輯：

這裏是button_text.xml文件代碼：

<?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> 

而且，​​文件代碼：

<?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

這樣的情況下，在這兒呢。請閱讀完整的答案。與android:textColor不同，android:background屬性不支持Color State List。要使android:background資產正常工作，您需要State List Drawables。因此，而不是res/color/創建res/drawable/目錄中的文件。這裏是代碼：

<?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> 

請注意使用android：drawable而不是android：color。 Android將使用該顏色資源並將其繪製出來。要完成這一步，您需要將顏色資源添加到res/values/colors.xml文件中。

Answer 2

首先，你有你的button_text.xml和​​轉移到drawable目錄。

然後設置，如：

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

Answer 3

試試這個它會幫助 你遵循這個

第1步： - >創建資源A button_text.xml /顏色/目錄。

<?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> 

步驟2： - >創建在res/drawble /目錄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> 

第三步： - 現在APPY在您的按鈕

<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" /> 

AKS我在任何查詢

Answer 4

如果你更好看的堆棧跟蹤異常，你會發現這一點：

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

您可以在這裏找到了解決辦法： Error : <item> tag requires a 'drawable' attribute or child tag defining a drawable
