Android 如何从代码中应用按钮样式？

我在

style.xml

中定义了自定义按钮样式：

<style name="buttonBlack">
    <item name="android:background">@drawable/selector_button_black_bg</item>
    <item name="android:textColor">@android:color/white</item>
</style>

我做错了什么

这是选择器：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@drawable/button_black_pressed" />
    <item android:state_focused="true" android:drawable="@drawable/button_black_focused" />
    <item android:drawable="@drawable/button_black_normal" />
</selector>

您应该使用

ContextThemeWrapper

Button button = new Button(new ContextThemeWrapper(context, R.style.buttonBlack));

它对我有用，你能发布你的选择器文件吗？罗宾，这对你有用吗？？？什么android版本和sdk？

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@drawable/button_black_pressed" />
    <item android:state_focused="true" android:drawable="@drawable/button_black_focused" />
    <item android:drawable="@drawable/button_black_normal" />
</selector>

Button button = new Button(new ContextThemeWrapper(context, R.style.buttonBlack));
