Android 如何筛选文本文件表单资产以仅显示特定结果

我正在从资产中加载文本文件，并在listview中使用json在我的文本文件中显示一些学校，我将我的文件粘贴到下面的\u name.json问题是我想筛选只显示名称为

“中学”的特殊学校

我如何筛选此行

JSONObject json2=new JSONObject（jsonresult）

仅显示名称为“MiddleSchool”的学校

遍历JSON对象，直到得到正确的项。没有用于此的内置函数。您可以在中找到所有必需的方法

我不会使用JSONObject。与注释一起使用要容易得多

 public String loadJSONFromAsset() {
    String json = null;
    try {

        InputStream is = getAssets().open("file_name.json");

        int size = is.available();

        byte[] buffer = new byte[size];

        is.read(buffer);

        is.close();

        json = new String(buffer, "UTF-8");
        jsonresult=json;

    } catch (IOException ex) {
        ex.printStackTrace();
        return null;
    }
    return json;

}
                    JSONObject json2 = new JSONObject(jsonresult);

        status = json2.getString("status");
        if (status.equals("1")) {
            message = "data";

            JSONArray school = json2.getJSONArray("data");

            for (int i = 0; i < school.length(); i++) {
                JSONObject object = school.getJSONObject(i);

                Category_ID.add(Long.parseLong(object
                        .getString("school_id")));
                Category_name.add(object.getString("name"));
            }
        }
        else {
                message = "error";
        }
        }
