java - 带有选项卡的 Activity 中的布局刷新问题

Question

它是一个带有Tabs 的Activity，我使用Volley 库 从API 获取数据。只有一个 Fragment。每当通过滑动或单击 Tab 更改 Tab 时，调用 API 的函数将使用不同的数据调用。

Problems:

1) 它每次在工作互联网上加载项目，但有时显示有时不显示。当我按下主页按钮(即 Activity 正在后台运行)，然后从打开的应用程序列表中选择应用程序时，它会显示数据。我必须通过按下主页按钮并从打开的应用程序中重新选择来暂停和恢复应用程序以查看更改。如果我锁定屏幕和解锁屏幕，它也会显示内容。

2) 类似于问题 1) 右上角有一个信息按钮，单击它会显示/隐藏布局。但有时当问题 1) 发生时，它的行为也相同。

3) 看起来也类似于 1) 和 2) 有 TextView (选项)在单击时显示/隐藏布局但有时当问题 1) 发生时它的行为也相同。

任何帮助将不胜感激，我的时间不多了......

Answer 1

这是我解决问题的方法:

首先，理解问题。

1. 在您获取餐厅列表的第一个 Activity 中，这很好。

2. 当餐厅被点击时，您将餐厅 ID 传递给 RestaurantDetailActivity 并执行 API 请求。

3. 在 API 请求中，您传递餐厅 ID 并获得响应。响应包含该餐厅所有类别的丢失以及该餐厅在所有类别中提供的所有菜肴的列表。这个非常重要。

4. 在此阶段，您只需要响应中的类别列表并开始为每个类别创建一个 fragment 。您将类别 ID 传递给每个 fragment 。

5. 然后每个 fragment 向在 Activity 级别(上面的第 3 点)调用的相同 API 发出 API 请求。每个 fragment 独立执行相同的请求，并仅提取属于该类别的菜单项列表。那是一种资源浪费。

6. 当 fragment 离开 View 时，它会被销毁，然后在用户滑回选项卡时重新创建。每次用户来到 fragment 时，它都会再次加载数据。这种重复加载数据导致设备无响应。

这就是我所做的。在第 3 步，当针对特定餐厅完成字符串请求并收到所有菜单项作为响应时。我在这个阶段为每个类别创建一个单独的菜单项列表，然后将列表传递给每个 fragment 。现在每个 fragment 只需要显示它从 Activity 中收到的列表。每个 fragment 不负责执行自己的字符串请求并将其解析为创建自己的项目列表。相反，它只是从 Activity 中接收列表并显示它。其中只有一个 API 请求是在 Activity 级别完成的。无论用户切换多少次标签页，都没有额外的 API 请求。
