通过在 json 值上使用 .toString 解决问题。

            try 
            {

                View view;
                for (int i = 0; i < list_lay.getChildCount(); i++) 
                {

                    TextView main = (TextView) view.findViewById(R.id.main);

                    String[] m=main.getTag().toString().split("::::");

                    j1.put("account_id",m[0]);

                    System.out.println("data_main1.getChildCount() => "+data_main1.getChildCount());

                    for (int k = 0; k < data_main1.getChildCount(); k++)

                        {
                            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，因为我做了很多次 json 数组和 json 对象，但从未见过这种错误。

所以现在我的问题是这个问题是怎么回事？

你已经建立了一个循环结构：j_classcontainsj1和j1contains j_class。

可能你想投入j1_class进去j_class。

    }catch(JSONException je){   
        je.printStackTrace();
    } catch (Exception se) {

还记得对它们进行字符串化。参见上面的片段：（toString（））；）希望它可以帮助那里的人；）
