Error:(728, 21) No resource found that matches the given name: attr 'colorMain'.

Error:(728, 21) No resource found that matches the given name: attr 'colorMain'.

Error:(729, 21) No resource found that matches the given name: attr 'listTextColor'.

<color name="colorMain">#fff</color> <color name="listTextColor">#fff</color>

I U SED在這裏：

`<EditText 
       android:id="@+id/edittxtPassword" 
       android:layout_width="match_parent" 
       android:layout_height="45dp" 
       android:background="@color/listTextColor" 
       android:hint="Enter your Password" 
       android:inputType="number" 
       android:maxLength="10" 
       android:paddingBottom="5dp" 
       android:paddingLeft="45dp" 
       android:paddingRight="5dp" 
       android:paddingTop="5dp" />` 

Answer 1

的問題是存在的colorMain和listTextcolor條目在styles.xml中

然後我刪除了條目，然後重建。建立成功。

Answer 2

創建res目錄「彩色」的文件夾，添加顏色資源文件，並在顏色XML文件中定義這樣的顏色

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