在Android中读取Json Array时出错

Question

JSON格式

}

代码-PageReports添加

public class PageReports implements Serializable{

    @SerializedName("data")
    @Expose
    private List<Datum> data = null;

    public List<Datum> getData() {
        return data;
    }

    public void setData(List<Datum> data) {
        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);
                            indicator.setViewPager(viewPager);
                        }
                    },
                    throwable -> throwable.printStackTrace()
            );
}

public static Map<String,String> authHeaderAccept(Context context) {
    Map<String, String> header = defaultHeader();
    header.put("Authorization","Bearer " + Preference.getInstance(context).getToken());
    return header;
}

我正在尝试读取，但始终会出错，如果我在JSON中只有一个值，我可以进行搜索，但是当它具有3时，它就没有搜索。

好像GSON（）类没有转换。 在这种情况下可以采取什么措施使该错误不再发生？ 更改JSON还是我尚未识别的代码中存在错误？

Answer 1

您的第二个data对象在[ options ]中丢失[及更高版本] ：

"options": {
        "left": {
            "goto": "+",

不管什么原因

做这个

"options": [{
            "left": {
                "goto": "+",

..并在结尾处使用相应的[]关闭数组
