一、在pages.json文件里边写上自定义属性

"navigationStyle": "custom"

二、在对应的index页面写上以下：

<view :style="{ height: headheight + 'px', backgroundColor: '#24B7FF', zIndex: 99, position: 'fixed', top: '0px', width: '100%' }">
</view>
<view class="head" :style="{ top: headheight + 'px', backgroundColor: '#24B7FF' }">
	<view>新乡市</view>
</view>
<view style="height: 100rpx;"></view>

三、在script标签的return里边写上

headheight: '',

四、在onLoad()周期里面写上

const systemInfo = uni.getSystemInfoSync();
const windowHeight = systemInfo.statusBarHeight;
this.headheight = windowHeight;

五、style

.head {
		display: flex;
		justify-content: center;
		align-items: center;
		position: fixed;
		height: 100rpx;
		width: 100%;
		z-index: 99;
	}

效果：
