按钮的Android主题样式不适用 [英] Android theme style for button not applying

问题描述

我的主要活动视图中有三个简单的按钮. 我想做的是将按钮样式应用于所有按钮，但我没有这样做.

I have three simple buttons in my main activity view. What I am trying to do is apply a buttonstyle to all my buttons but I fail to do so.

这是我的xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/minecraft_portrait"
    android:alpha="0.75"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/txtAppName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:text="@string/app_name_readable"
        android:textSize="32sp"
        android:textColor="@android:color/white" />

    <Button
        android:id="@+id/btnCrafting"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:background="@drawable/button_selector"
        android:onClick="craftingButtonClicked"
        android:text="@string/crafting" />

    <Button
        android:id="@+id/btnServerCommands"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@id/btnCrafting"
        android:layout_below="@id/btnCrafting"
        android:layout_marginTop="20dp"
        android:background="@drawable/button_selector"
        android:onClick="commandsButtonClicked"
        android:textColor="@android:color/white"
        android:text="@string/servercommands" />

    <Button
        android:id="@+id/btnVideos"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@id/btnServerCommands"
        android:layout_below="@id/btnServerCommands"
        android:layout_marginTop="20dp"
        android:background="@drawable/button_selector"
        android:onClick="videosButtonClicked"
        android:text="@string/videos" />

</RelativeLayout>

这是res/values文件夹中的style.xml:

And this is my style.xml from the res/values folder:

<resources xmlns:android="http://schemas.android.com/apk/res/android">

    <style name="AppBaseTheme" parent="android:Theme.Light">
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <item name="android:buttonStyle">@style/ButtonTheme</item>
    </style>

    <style name="ButtonTheme" parent="android:Widget.Button">
        <item name="android:textColor">@android:color/white</item>
        <item name="android:background">@android:color/darker_gray</item>
        <item name="android:typeface">monospace</item>
        <item name="android:textSize">32sp</item>
    </style>
</resources>

清单文件中的主题定义:

And my theme definition from the manifest file:

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
....

有什么想法为什么风格不适用于我的按钮? 我将一个按钮的文本颜色设置为白色，只是为了看到任何区别.

Any ideas why the style isn't applying to my buttons? I have set the textcolor of one button to white just to see any difference.

推荐答案

在使用支持库时，按钮样式必须应用为:

When using the support library the button style must be applied as:

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:buttonStyle">@style/ButtonTheme</item>
    <item name="buttonStyle">@style/ButtonTheme</item>
</style>

注意重复项，但没有名称空间

Note the duplication but with no namespace
