我在应用主题 styles.xml 中遇到错误

I am having errors in styles.xml in app theme

这是我的 AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.sammar.materialdeisgn">

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme.NoActionBar">
    <activity
        android:name=".MainActivity"
        android:label="YourAppName"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
 </application>

</manifest>

这是我的 styles.xml

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

我收到以下错误:

1)Error:No resource found that matches the given name (at 'theme' with value '@style/AppTheme.NoActionBar').



 2)Error:No resource found that matches the given name (at 'theme' with value '@style/AppTheme.NoActionBar').



 3)Error:No resource found that matches the given name (at 'theme' with value '@style/AppTheme.NoActionBar').



 4)Error:No resource found that matches the given name (at 'theme' with value '@style/AppTheme.NoActionBar').



 5)Error:Execution failed for task ':app:processDebugResources'.

aapt

尝试使用:

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

因为您的应用可能使用了 name="AppTheme"。这样。

您已经在样式中声明了 No action Bar,那么在清单中就不需要了,只需在清单中使用即可

 <activity
            android:name=".MainActivity"
            android:label="YourAppName"
            android:theme="@style/AppTheme">

未引用您的清单样式 NoActionBar 主题,因此请添加以下行

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

所以你的Style.xml看起来像

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- 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="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>
</resources>
