我不明白是什么事，因为我会在这之前尝试这么多的时间。因此，任何机构可以帮助我
I do not understand what is happened because i will try so many time before this. So any body can help me
答案
问题的决心通过JSON值使用的ToString。
problem resolve by using .toString on json value.
前
try
{
View view;
for (int i = 0; i < list_lay.getChildCount(); i++)
{
view=list_lay.getChildAt(i);
JSONObject j1=new JSONObject();
TextView main = (TextView) view.findViewById(R.id.main);
String[] m=main.getTag().toString().split("::::");
j1.put("account_id",m[0]);
j1.put("address_1",m[1]);
j1.put("address_2",m[2]);
j1.put("city",m[3]);
j1.put("email",m[4]);
j1.put("id",m[5]);
j1.put("manager_name",m[6]);
j1.put("name",m[7]);
j1.put("zip",m[11]);
j1.put("state",m[9]);
j1.put("phone",m[8]);
j1.put("website",m[10]);
LinearLayout data_main1=(LinearLayout) view.findViewById(R.id.data_main1);;
JSONArray j_class=new JSONArray();
System.out.println("data_main1.getChildCount() => "+data_main1.getChildCount());
for (int k = 0; k < data_main1.getChildCount(); k++)
{
View view1=data_main1.getChildAt(k);
TextView name = (TextView) view1.findViewById(R.id.name);
CheckBox cb = (CheckBox) view1.findViewById(R.id.checkBox1);
if(cb.isChecked())
{
JSONObject j1_class=new JSONObject();
String [] l=name.getTag().toString().split("::::");
j1_class.put("id",l[0].toString());
j1_class.put("teacher",l[1].toString());
j1_class.put("name",l[2].toString());
j1_class.put("enrolled","yes".toString());
j_class.put(j1.toString());
System.out.println("j1 => "+j1.toString());
System.out.println("j_class => "+j_class.toString());
}
}
j1.put("classes", j_class.toString());
json.put(j1.toString());
System.out.println("json => "+json.toString());
}
System.out.println("array => "+json.toString());
}
catch (Exception e)
{
// TODO: handle exception
}
不过在此之前我还在迷惑BCZ我正在做这么多时间JSON数组和JSON对象，但从来没有见过那样的错误。
But i'm still confuse bcz before this i'm making so many time json array and json object but never ever see that kind of error.
所以现在我的问题是怎么回事这个问题？
推荐答案
您已经建立了一个圆形结构： j_class 包含 J1 和 J1 包含 j_class 。
You have built up a circular structure: j_class contains j1 and j1 contains j_class.
也许你希望把 j1_class 到 j_class 代替。
这篇关于java.lang.StackOverflowError错误显示了制作JSON数组对象？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
