离子：离子头像不显示

Question

item-avatar 在我的项目中不起作用，它根本没有显示 item-avatar 元素。

  <ion-content padding>
  <ion-list>
      <ion-list-header>
          Recent Conversations
      </ion-list-header>
      <ion-item>
          <item-avatar start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </item-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>

      <ion-item item-start>
          <item-avatar start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </item-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>

      <ion-item slot="start">
          <item-avatar start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </item-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>
  </ion-list>
</ion-content>

Answer 1

你在<item-avatar start>犯了一个错误

改为：

<ion-avatar item-start>
    <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
 </ion-avatar>

工作代码：

<ion-content padding>
  <ion-list>
      <ion-list-header>
          Recent Conversations
      </ion-list-header>
      <ion-item>
          <ion-avatar item-start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </ion-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>

      <ion-item item-start>
          <ion-avatar item-start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </ion-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>

      <ion-item slot="start">
         <ion-avatar item-start>
              <img src="https://ionicframework.com/docs/demos/api/avatar/avatar.svg">
          </ion-avatar>
          <ion-label>
              <h2>Finn</h2>
              <h3>I'm a big deal</h3>
              <p>Listen, I've had a pretty messed up day...</p>
          </ion-label>
      </ion-item>
  </ion-list>
</ion-content>

Answer 2

你犯了一个错误

改为：

<ion-list>
  <ion-item>
   <ion-avatar item-start>
     <img src="img/avatar-cher.png">
   </ion-avatar>
   <h2>Cher</h2>
   <p>Ugh. As if.</p>
  </ion-item>
</ion-list>

您应该删除其他元素上的额外“item-start”。仅在头像“item-start”上使用

你需要检查这个答案。
