原本是用的没有设置 itemList: ["拍照", "选择本地相册"],但是在安卓手机中点击图标不能弹出下图2,而是直接打开了手机相册,所以需要自己写一个数组展示

index.vue//[点击相机图片弹出拍照和选择本地相册的弹框,去选择/上传成功展示图片]

     <view class="section section2 ">
        <label class="section__title section__title1"
          ><text style="color:red;"></text>
          <text style="margin-left:10rpx;">上传图片</text>
