如何处理 react-native-multiple-select getSelectedItemsExt() 函数？

Question

我正在构建一个 React Native 应用程序并找到了我按照文档实施的 react-native-multiple-select 库 https://www.npmjs.com/package/react-native-multiple-select . The view is being displayed but the selected items are not showing up, only the counter of selected items works. I think it's because I don't have the control over how its function getSelectedItemsExt() works and from my researchs on internet like React-native-multiple-select: Cannot read the property 'getSelectedItemsExt' of undefined 我只发现我应该这样做

  <View>
       { this.multiselect
      ?
     this.multiselect.getSelectedItemsExt()
      :
      null}
    </View>

。虽然它有助于摆脱红屏，但它不显示项目。那么你能告诉我如何管理吗

this.multiselect.getSelectedItemsExt()

并显示我的项目。任何帮助深表感谢。提前致谢。

我可以在整个问题中猜测您正在将 hideTags 道具传递给 MultiSelect 组件，即您在组件内部 < 多选隐藏标签>。这个 hideTags 是你的问题，因为 它的作用如其名，即 它不显示你在FlatList 或任何组件。如果您希望显示这些值，请从组件内部删除 hideTags，您应该会显示您的项目。那么你还想自定义这个库的输出，它的颜色和 InputField 样式然后前往你的反应本机应用程序的 root，然后转到 node-module -> react-native-multiple-select -> Library 在那里你会找到你可以自定义的核心文件休闲.
