我不明白发生了什么,因为在此之前我会尝试很多次。所以任何人都可以帮助我

回答

通过对 json 值使用 .toString 解决问题。

            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
}

但在此之前,我仍然对 bcz 感到困惑,我制作了很多次 json 数组和 json 对象,但从未见过那种错误。

那么现在我的问题是这个问题是怎么回事?

最佳答案

您已经建立了一个循环结构:j_class 包含 j1j1 包含 j_class

可能您想将 j1_class 放入 j_class 中。
