我正在努力使我的应用符合Google的材料设计最佳做法,但出于某种原因,我在v21 \ styles.xml中设置的项目从未应用于我的应用程序。
请查看下面的v21样式和Android Manifest文件,并告诉我我做错了会导致我的自定义AppTheme无法显示。
V21 \ styles.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- android theme colors -->
<!-- Main theme colors -->
<!-- your app branding color for the app bar -->
<item name="colorPrimary">#F44336</item>
<!-- darker variant for the status bar and contextual app bars -->
<item name="colorPrimaryDark">#FFD600</item>
<!-- theme UI controls like checkboxes and text fields -->
<item name="colorAccent">#FFD600</item>
</style>
</resources>
的AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.foo"
android:versionCode="1"
android:versionName="1.0" >

<application

android:icon="@drawable/launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme"> **Theme set here**
<activity

android:configChanges="orientation|keyboardHidden|screenSize"
android:label="@string/app_name"
android:theme="@style/FullscreenTheme" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<!-- Test:USB otg -->
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>
<!-- Test:USB otg -->
<meta-data

android:resource="@xml/device_filter" />
</activity>
</application>
</manifest>
我正在运行最新版Android,API 23的设备上测试此代码,所以我不确定为什么API 21+的样式不会被触发。
下面我还发布了我的App的其他平台版本的xml文件,似乎应用程序正在使用其中一个。为了完整起见,我已将这些包括在内。
V14 \ styles.xml
<resources>
<!--
Base application theme for API 14+. This theme completely replaces
AppBaseTheme from BOTH res/values/styles.xml and
res/values-v11/styles.xml on API 14+ devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- API 14 theme customizations can go here. -->
</style>
</resources>
V11 \ styles.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!--
Base application theme for API 11+. This theme completely replaces
AppBaseTheme from res/values/styles.xml on API 11+ devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">

</style>
<style name="FullscreenTheme" parent="android:Theme.Holo">
<item name="android:actionBarStyle">@style/FullscreenActionBarStyle</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowBackground">@null</item>
<item name="metaButtonBarStyle">?android:attr/buttonBarStyle</item>
<item name="metaButtonBarButtonStyle">?android:attr/buttonBarButtonStyle</item>
</style>
<style name="FullscreenActionBarStyle" parent="android:Widget.Holo.ActionBar">
<item name="android:background">@color/black_overlay</item>
</style>
</resources>
值\ styles.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!--

</style>
<!-- Application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

<item name="android:windowBackground">@null</item>

<item name="metaButtonBarButtonStyle">@style/ButtonBarButton</item>

<style name="ButtonBar">

<item name="android:paddingTop">5dp</item>
<item name="android:paddingRight">2dp</item>
<item name="android:paddingBottom">0dp</item>

<style name="ButtonBarButton" />
</resources>
为什么我的应用程序永远不会显示我在v21 \ styles.xml中列出的样式?
答案 0 :(得分:1)
我发现了错误。
基本上,在您的清单文件中,您正在为应用程序设置“AppTheme”。但是,您还要为活动设置主题(FullscreenTheme)。
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
...
<application
android:theme="@style/AppTheme"> **Theme set here**
<activity
android:theme="@style/FullscreenTheme" >
...
</activity>
</application>
</manifest>
要修复,我看到两个选项:
<强>选项1:强>
您可以删除:
android:theme="@style/FullscreenTheme"
<强>选项2:强>
如果您确实需要使用FullscreenTheme,请将其添加到v21 / styles.xml。然后,您可以在v21中进行不同的设置。
这是你的电话!
