我在编程方面很菜鸟,我一直在学习一些教程,并且我更改了样式或颜色或其他内容,现在我遇到的问题是,当我尝试创建按钮时,它以特定颜色开始为此,它不允许我设置我以前做过的背景资源。
我怎样才能让按钮显示这个drawable?
这是 xml(尽管这发生在我所有的布局中)

这是我想使用的drawable
这是我设置了背景但未显示的按钮
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/button_black_background"/>
这些是我的颜色
<resources>
<color name="colorPrimary">#721100</color>
<color name="colorPrimaryDark">#3F0101</color>
<color name="colorAccent">#FF5AB0</color>
<color name="colorTextPrimary">#212121</color>
<color name="colorTextSecondary">#757575</color>
</resources>
这些是我的风格
<resources>

<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
