制作json数组但显示错误。尝试以下链接但没有发生任何事情： -
java文件

我不明白发生了什么事，因为我会在此之前尝试这么多时间。所以任何身体都可以帮助我
ANSWER
通过在json值上使用.toString来解决问题。
离
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
}
但是我仍然混淆了bcz之前我正在制作这么多时间的json数组和json对象，但从来没有看到过那种错误。
所以现在我的问题是这个问题出现了什么？
答案 0 :(得分：4)
您构建了一个循环结构：j_class包含j1，j1包含j_class。
您可能希望将j1_class改为j_class。
答案 1 :(得分：0)
JSONObject json = new JSONObject();
try {
json.append("msisdn", new Object());

还记得做Stringify他们。见上面代码片段：（toString（））;）希望它可以帮助那里的人;）
