下面是我的代码，我只想过滤名称为小学的学校，但我的代码不过滤它，我删除了这一行if (object.getString("title") =="Elementary Schools")，然后显示所有学校我如何过滤它？

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);
        if (object.getString("title").equals("Elementary Schools")){
            Category_ID.add(Long.parseLong(object.getString("school_id")));
            Category_name.add(object.getString("name"));
        }
    }
}

JSON响应：

String title = object.getString("title");
if(title.equals("Elementary Schools"))
{
   //do your code
}

title.equalsIgnoreCase("Elementary Schools");你也可以使用

JUst do 

String title = object.getString("title");
if(title.equals("Elementary Schools"))
{
// Do you stuff
}

you can also use
if (object.getString("title").equalsIgnoreCase("Elementary Schools")
{`enter code here
// do you stuff
}

// 我刚刚注意到你的 if 语句后的 (;) 删除它并测试你的代码。
