Question

任何人都可以解释为什么我在这里收到此错误？这是res / layout文件夹中的styles.xml

<resources>

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <item name="android:buttonStyle">@style/ButtonTheme</item>
    </style>


   <style name="ButtonTheme" parent="android:Widget.Button">
        <item name="android:textColor">@color/Black</item>
        <item name="android:background">@color/LightGrey</item>
        <item name="android:textSize">23sp</item>
        <padding 
            android:left="1dp"
             android:top="1dp"
             android:right="1dp"
             android:bottom="1dp"
             /> 
    </style>

</resources>

错误似乎发生在ButtonTheme

的填充部分

Answer 1

您应该使用

<item name="android:padding">1dp</item>

而不是

<padding 
        android:left="1dp"
         android:top="1dp"
         android:right="1dp"
         android:bottom="1dp"
         />

Answer 2

您错过了命名空间声明。尝试将xmlns:android="http://schemas.android.com/apk/res/android"插入<resources>

即

<resources xmlns:android="http://schemas.android.com/apk/res/android">

Answer 3

你必须使用android前缀命名空间，例如： - android：name =＆＃34; AppBaseTheme＆＃34;

    <?xml version="1.0" encoding="utf-8"?>
    <resources xmlns:android="http://schemas.android.com/apk/res/android" >
    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style
         android:name="AppBaseTheme"
         android:parent="Theme.AppCompat.Light" >

Answer 4

你错过了架构uri，并且填充格式不正确。

<resources xmlns:android="http://schemas.android.com/apk/res/android">

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <item name="android:buttonStyle">@style/ButtonTheme</item>
    </style>

    <style name="ButtonTheme" parent="android:Widget.Button">
        <item name="android:textColor">@color/Black</item>
        <item name="android:background">@color/LightGrey</item>
        <item name="android:textSize">23sp</item>
        <item name="android:paddingLeft">1dp</item>
        <item name="android:paddingRight">1dp</item>
        <item name="android:paddingTop">1dp</item>
        <item name="android:paddingBottom">1dp</item>
    </style>

</resources>
