this.data = data;
}
}
private void getReportPages(String id) {
if (subscription != null) {
subscription.unsubscribe();
}
subscription = RxUtil.appleHandlerStartFinish(
RestBuilder.api().getReportPage(RestParams.authHeaderAccept(getContext()), id),
() -> base.displayProcess(),
() -> base.dismissProcess())
.compose(RxUtil.applySchedulers())
.subscribe(
pageReports -> {
// LogUtil.e("JSON: ", SuApp.getInstance().gson().toJson(pageReports));
if (pageReports != null && pageReports.getData() != null && pageReports.getData().size() > 0) {
currentDataReport.setDataPages(pageReports.getData());
viewPager.setOffscreenPageLimit(pageReports.getData().size());
mPagerAdapter = new ReportPagerAdapter(getChildFragmentManager(), pageReports.getData());
viewPager.setAdapter(mPagerAdapter);

},

我正在尝试读取但总是出错，如果我在 JSON 中只有一个值，我可以进行搜索，但是当它有 3 时它没有。
好像 GSON () 类没有转换。在这种情况下可以做些什么以使错误不再发生？更改 JSON 还是代码中存在我尚未识别的错误？
【问题讨论】：
-
乍一看，您似乎在尝试将 JSON 直接加载到对象中，而 JSON 在 Java 对象没有数组的位置包含一个数组。您能否确定第 1 行第 125 列中的哪个字段并对照您的 Java 对象定义进行检查？
-
@Hugg 请发布您的
pageReports型号代码 -
@Kulebin 代码添加

这并不能真正告诉我们任何事情。正如 Gewure 指出的那样（我在错误中遗漏了），问题出在“选项”元素上：第一个 Datum 将 this 作为数组，第二个只是一个对象。这意味着我们需要查看 options 字段，这意味着您发布的仅包含 Datum 对象的 PageReports 也意味着没有 Datum 也没有任何意义，如果选项位于另一个包含的对象中，那么查看它会很有用也。但希望你现在已经足够了：听起来 JSON 中第一个 Datum 中的数组是错误的。需要同时接受array + obj吗？

@Rup.现在我明白错误了，谢谢。
