Question

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'.

Answer 1

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name =“AppTheme”。那样。

Answer 2

您已在样式中声明了无操作栏，因此不需要在清单

中使用清单

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

Answer 3

您的清单样式未引用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看起来像是

<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>

我在app主题中的styles.xml中遇到错误
