taro Ui Vue3 h5 安卓机输入框弹窗键盘时，会把页面顶上去 代码举例

感谢您的提问！以下是 Taro Ui Vue3 中防止 H5 安卓机在输入框弹窗键盘时将页面顶上去的一个例子：

<template>
  <div>
    <AtButton type="primary" @click="toggleModal">弹出模态框</AtButton>
    <AtModal :isOpened="isOpened" @close="handleClose">
      <AtModalHeader>标题</AtModalHeader>
      <AtModalContent>
        <div class="input-wrapper">
          <input type="text" placeholder="请输入内容" @focus="handleFocus" @blur="handleBlur">
        </div>
      </AtModalContent>
      <AtModalAction>
        <Button onClick="handleClose">取消</Button>
        <Button onClick="handleClose">确定</Button>
      </AtModalAction>
    </AtModal>
  </div>
</template>

<script>
import { defineComponent, onMounted, ref } from 'vue'
import { AtButton, AtModal, AtModalHeader, AtModalContent, AtModalAction } from 'taro-ui-vue3'

export default defineComponent({
  name: 'ModalExample',

  components: {
    AtButton,
    AtModal,
    AtModalHeader,
    AtModalContent,
    AtModalAction,
  },

  setup() {
    const isOpened = ref(false)

    const toggleModal = () => {
      isOpened.value = !isOpened.value
    }

    const handleClose = () => {
      isOpened.value = false
    }

    const handleFocus = () => {
      if (/Android/gi.test(navigator.userAgent)) {
        setTimeout(() => {
          document.activeElement.scrollIntoViewIfNeeded()
        }, 100)
      }
    }

    const handleBlur = () => {
      if (/Android/gi.test(navigator.userAgent)) {
        setTimeout(() => {
          document.activeElement.scrollIntoViewIfNeeded()
        }, 100)
      }
    }

    onMounted(() => {
      if (/Android/gi.test(navigator.userAgent)) {
        const height = window.innerHeight
        const timer = setInterval(() => {
          if (window.innerHeight !== height) {
            document.body.style.height = window.innerHeight + 'px'
            height = window.innerHeight
          }
        }, 100)
        return () => clearInterval(timer)
      }
    })

    return {
      isOpened,
      toggleModal,
      handleClose,
      handleFocus,
      handleBlur,
    }
  },
})
</script>

<style scoped>
.input-wrapper {
  padding: 20px;
}

input {
  width: 100%;
  height: 50px;
  font-size: 18px;
  border: none;
  border-bottom: 1px solid #ccc;
  outline: none;
}
</style>

这个例子中，我们使用了 Taro Ui Vue3 的 AtModal 组件，同时在输入框的 focus 和 blur 事件中，通过调用 `scrollIntoViewIfNeeded()` 方法，将输入框滚动到可视区域内。同时，在组件挂载时，我们通过监听窗口大小的变化，动态设置 body 的高度，以防止页面出现滚动条。希望这个例子能够帮到您！
