我试图让我的TextView在黑色背景上有白色文字。这就是我所拥有的：
<TextView
android:id="@+id/items_category"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Category"
style="@style/Category" />
在我的styles.xml中，我有：
<style name="Category">
<item name="android:textColor">#FFFFFF</item>
<item name="android:textSize">40sp</item>
<item name="android:colorBackground">#000000</item>
</style>
字体大小和颜色正确，但背景颜色不起作用。我究竟做错了什么？谢谢你的时间

或您自己定义的颜色：
<item name="android:background">#000000</item>
答案 1 :(得分：0)
如果您在任何视图中提供样式，那么它将继承您定义样式的所有属性..
现在，如果要更改任何属性，则必须在视图中定义它，以便覆盖该视图的该属性。
您可以在Textview中设置如下所示的背景颜色，这样它将覆盖样式背景属性的值：
<item name="android:background">#000000</item>
