如何使用Java合并JSON数组? [英] how to merge json array using java?

问题描述

我正在使用android studio.

I am working on android studio.

我有两个json数组，例如...

I have two json arrays such as...

jsonArray1:

jsonArray1:

[
  {"file":"ay.m4a", "version":"5"}, 
  {"file":"kt.m4a", "version":"5"}
]

jsonArray2:

jsonArray2:

[
  {"file":"hh.m4a", "version":"7"}, 
  {"file":"sh.m4a", "version":"7"}
]

然后，我要像这样合并这些数组...

Then, I want to merge these arrays like this...

jsonArrayMerged:

jsonArrayMerged:

[
  {"file":"ay.m4a", "version":"5"}, 
  {"file":"kt.m4a", "version":"5"}, 
  {"file":"hh.m4a", "version":"7"}, 
  {"file":"sh.m4a", "version":"7"}
]

我该怎么做?

推荐答案

尝试下面的代码，这将提供您想要的结果.

Try below code, This will give your desired result.

JSONArray jsonArray = new JSONArray();
JSONArray jsonArray1 = new JSONArray();
try {
    for (int i = 0; i < jsonArray1.length(); i++) {
        JSONObject jsonObject = jsonArray1.getJSONObject(i);
        jsonArray.put(jsonObject);
    }
} catch (JSONException e) {
    e.printStackTrace();
}

现在使用 jsonArray 将所有已合并的jsonObject

Now use jsonArray which is having all merged jsonObject
