1.新建项目
2. 添加 计时器,按钮组件
<?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:alignment="center" ohos:orientation="vertical"> <TickTimer ohos:id="$+id:tick_1" ohos:height="match_content" ohos:width="match_content" ohos:text_color="red" ohos:text_size="50vp" ohos:text_alignment="center" ohos:layout_alignment="center" /> <Button ohos:id="$+id:bt_1" ohos:height="match_content" ohos:width="match_content" ohos:margin="30vp" ohos:clickable="false" ohos:text="准备!" ohos:text_color="red" ohos:text_size="50vp" ohos:text_alignment="center" ohos:layout_alignment="center"/> </DirectionalLayout>
3.抢红包业务逻辑
