Android默认按钮样式无法正常工作

Question

我正在尝试设置我的样式,使所有按钮成为特定的颜色组合,特别是蓝色和白色文本.这是我的主要styles.xml:

<resources>
    <style name="CustomTheme" parent="MaterialDrawerTheme.Light.DarkToolbar">
        <!-- various items -->

        <item name="android:buttonStyle">@style/ButtonStyle</item>
    </style>

    <!-- a couple of other styles -->

    <style name="ButtonStyle" parent="android:style/Widget.Button">
        <item name="android:textSize">19sp</item>
        <item name="android:textColor">@color/primaryTextContrast</item>
        <item name="android:background">@color/primary</item>
    </style>
</resources>

在清单中:

 <application
        android:name=".CustomApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/application_name"
        android:theme="@style/CustomTheme">

color/primary是深蓝色,color/primaryTextContrast是白色的.在棒棒糖上,按钮看起来很完美.在4.1设备上,它是浅灰色和黑色文本.我发现这样做的每一个资源都与我正在做的完全一样,所以我不知道我在这里缺少什么.

我在基本样式定义中控制文本大小也遇到了类似的问题.

更新:这是颜色.

<resources>
    <color name="primary">#3F51B5</color>
    <color name="dark">#303F9F</color>
    <color name="accent">#FFCA28</color>
    <color name="background">@android:color/white</color>
    <!-- Color for text displayed on top of the primary or dark color -->
    <color name="primaryTextContrast">@android:color/white</color>
    <!-- Color for text displayed on the background color (which I think will always be white) -->
    <color name="basicText">@color/primary</color>
    <!-- Color for text displayed on the accent color -->
    <color name="accentText">#303F9F</color>
</resources>

这是v19/styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="FullscreenTheme" parent="MaterialDrawerTheme.Light.DarkToolbar.TranslucentStatus">
        <item name="android:windowTranslucentNavigation">true</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowTranslucentStatus">true</item>
    </style>
</resources>

这是v21:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" parent="CustomTheme">
        <item name="android:windowContentTransitions">true</item>
        <item name="android:windowAllowEnterTransitionOverlap">true</item>
        <item name="android:windowAllowReturnTransitionOverlap">true</item>
        <item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
        <item name="android:windowSharedElementExitTransition">@android:transition/move</item>
    </style>
</resources>

我认为其中任何一个都不能使它在5.1上正常工作.

Answer 1

使用AppCompat 22.1.+(也22.2.0应该工作),我定义了一个样式:

<style name="MyApp.Button.Red" parent="Base.Widget.AppCompat.Button">
    <item name="colorButtonNormal">@color/primary</item>
    <item name="android:colorButtonNormal">@color/primary</item>
    <item name="android:textColor">@android:color/white</item>
</style>

然后使用命名空间中的native theme属性在一个按钮中应用主题android,如Chris Banes的这篇精彩帖子所述.

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/sign_up_button"
    android:theme="@style/MyApp.Button.Red" />
