设置组件不同状态下的背景颜色

  今天来分享一下如何设置组件不同状态下的背景颜色，这里我定义了一个Ability，布局页面放了一个按钮和单选按钮代码如下

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:orientation="vertical">

    <RadioButton
        ohos:id="$+id:radChoose"
        ohos:height="50vp"
        ohos:width="match_content"
        ohos:text_size="30vp"
        ohos:background_element="gray"
        ohos:text="选我吧"/>
    <Button
        ohos:id="$+id:btnDisable"
        ohos:height="match_content"
        ohos:width="match_content"
        ohos:text="禁用"
        ohos:text_size="30vp"
        ohos:background_element="gray"/>
</DirectionalLayout>
