未设置 Android 主题 [英] Android theme not being set

问题描述

我有一个拒绝应用于活动的主题 - 没有应用任何样式.如果我不为 <Button> 提供 layout_width/layout_height 属性，它也会出现运行时错误，显示 按钮 类没有被应用.

I have a theme that refuses to be applied to activities - none of the styles are applied. If I don't supply the layout_width/layout_height attributes for <Button> it also gets a runtime error, showing that the Button class isn't being applied.

/res/values/themes.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme" parent="android:style/Theme.Black">
        <item name="android:windowNoTitle">true</item>
        <item name="android:buttonStyle">@style/Button</item>
        <item name="android:windowBackground">@color/page_background_light</item>
        <item name="android:textAppearance">@style/TextAppearance</item>
    </style>
</resources>

/res/values/styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="TextAppearance" parent="@android:style/TextAppearance">
        <item name="android:textSize">12sp</item>
        <item name="android:textColor">@color/darkblue</item>
    </style>
    <style name="Button" parent="@android:style/Widget.Button">
        <item name="android:layout_width">fill_parent</item> 
        <item name="android:layout_height">wrap_content</item>
        <!--<item name="android:textColor">#3C2F4F</item>
        <item name="android:textSize">20dip</item>-->
    </style>
</resources>

和相关的清单设置:

<application android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/Theme">

我遗漏的明显错误是什么?

What's the obvious mistake I'm missing?

推荐答案

我也一直在为此苦苦挣扎，我想我终于找到了可能的问题所在——也许是一样的.

I've been struggling with this as well, and think I've finally found what may have been the problem - perhaps it is the same.

我在 resvalues 文件夹中定义了自定义主题，但在 values-v11 和 values-v14 文件夹中没有.我认为这使得在某些设备(特别是我正在测试的 2！)中，主题无法应用，因为它不存在.

I had the custom theme defined in the resvalues folder, but not in the values-v11 and values-v14 folders. Which I think made it so that in some devices (specially the 2 I was testing with!), the theme could not be applied because it did not exist.

我现在看到在我的自定义主题中设置的属性(在应用程序级别应用)生效.

I now see the properties set in my custom theme (applied at the application level) taking effect.
