Question

我正在尝试使用以下代码合并android中的两个json对象：

Iterator<?> i1 = store_ordinary_data.keys();
Iterator<?> i2 = store_premium_data.keys();
while(i1.hasNext()) {
    tmp_key = (String) i1.next();
    mergedObj.put(tmp_key, store_ordinary_data.get(tmp_key));
}
while(i2.hasNext()) {
    tmp_key = (String) i2.next();
    mergedObj.put(tmp_key, store_premium_data.get(tmp_key));

生成的合并JSON应该包含5个数据。但是缺少一个数据。我在上面的代码中做错了什么？

编辑JSON：

缺少的部分是第一个JSON中的酒店。我认为问题是当第一次运行时，缺少的部分存在。但是当第二次运行时，因为第二个json也包含＆＃39;酒店＆＃39;关键的旧酒店似乎已被覆盖。如何使其成为一个添加操作，而不是覆盖一个

编辑：

我按如下方式修改了代码，现在获得了JSON异常：

JSONObject mergedObj = new JSONObject();
                    Iterator<?> i1 = store_ordinary_data.keys();
                    Iterator<?> i2 = store_premium_data.keys();
                    while(i1.hasNext()) {
                        tmp_key = (String) i1.next();
                        mergedObj.put(tmp_key, store_ordinary_data.get(tmp_key));
                    }
                    while(i2.hasNext()) {
                        tmp_key = (String) i2.next();
                        if(mergedObj.has(tmp_key)){
                            JSONArray jsonexsarr=mergedObj.getJSONArray(tmp_key);
                            jsonexsarr.put(store_premium_data.get(tmp_key));
                            mergedObj.put(tmp_key,jsonexsarr);
                        }
                        else
                        {
                        mergedObj.put(tmp_key, store_premium_data.get(tmp_key));
                        }

                    }

代码中的问题是，当添加第二个json中的两个酒店时，它们会在第一个数组中添加一个数组。我希望将这两个酒店作为对象添加到第一个数组中。

Answer 1

在原始代码中，可能有两个重复的键，一个值在第二个循环中被覆盖。
