Question

i want to resolve my mistake pls help me

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@Color/ColorPrimary</item>

        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@Color/ColorAccent</item>

    </style>         

android say: Error:(9, 34) No resource found that matches the given name (at 'colorAccent' with value '@Color/ColorAccent').

Answer 1

检查colors.xml中名称id的位置以及大小写和拼写是否正确，如您在样式文件中提到的那样。

Answer 2

Xml cannot allow capitalization. So the file name should be color and not Color Be careful with cases. Attributes are like variables, start with small letters.

Show us your colors.xml

Answer 3

<resources>

    <!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/ColorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/ColorAccent</item>
    </style>
<style name="Button_style" parent="@android:style/Widget.Button">
    <item name="android:textSize">25sp</item>
        <item name="android:background">#ffffad2f</item>
        <item name="android:textColor">#fff</item>
        <item name="android:textStyle">bold</item>
    </style>
</resources>
