用uniapp写一个新闻界面

好的，以下是一个简单的新闻界面的示例代码：

<template>
  <view class="news">
    <view class="news-header">
      <text class="news-header-title">今日新闻</text>
    </view>
    <view class="news-list">
      <view class="news-item" v-for="(item, index) in newsList" :key="index">
        <view class="news-item-image">
          <image :src="item.image"></image>
        </view>
        <view class="news-item-content">
          <text class="news-item-title">{{item.title}}</text>
          <text class="news-item-summary">{{item.summary}}</text>
        </view>
      </view>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      newsList: [
        {
          title: "新闻标题1",
          image: "https://dummyimage.com/200x200/f0f0f0/999999.png",
          summary: "新闻简介1"
        },
        {
          title: "新闻标题2",
          image: "https://dummyimage.com/200x200/f0f0f0/999999.png",
          summary: "新闻简介2"
        },
        {
          title: "新闻标题3",
          image: "https://dummyimage.com/200x200/f0f0f0/999999.png",
          summary: "新闻简介3"
        }
      ]
    };
  }
};
</script>

<style>
.news {
  display: flex;
  flex-direction: column;
  height: 100%;
}

.news-header {
  height: 50px;
  background-color: #f5f5f5;
  display: flex;
  align-items: center;
  justify-content: center;
}

.news-header-title {
  font-size: 20px;
  font-weight: bold;
}

.news-list {
  flex: 1;
  display: flex;
  flex-direction: column;
  padding: 20px;
}

.news-item {
  display: flex;
  flex-direction: row;
  margin-bottom: 20px;
}

.news-item-image {
  width: 200px;
  height: 200px;
  margin-right: 20px;
  overflow: hidden;
}

.news-item-image image {
  width: 100%;
  height: 100%;
  object-fit: cover;
}

.news-item-content {
  flex: 1;
  display: flex;
  flex-direction: column;
}

.news-item-title {
  font-size: 18px;
  font-weight: bold;
  margin-bottom: 10px;
}

.news-item-summary {
  font-size: 14px;
  color: #999;
}
</style>

这个示例代码使用了 `flex` 布局，将新闻列表垂直排列在一个容器中。每个新闻条目由一个图片和标题、简介组成。示例代码中的图片使用了一个占位图片，实际使用时需要替换成真实图片的 URL。
