如何在Android中将单个字符串转换为JsonArray？

试试这个，

// Create JSonArrayJSONArray jArray = new JSonArray();while (managedCursor.moveTonext()){    final String number = managedCursor.getString(number1);    final String type2 = managedCursor.getString(type1);    final String date = managedCursor.getString(managedCursor.getColumnIndexOrThrow("date")).toString();    Date date1 = new Date(Long.valueOf(date));    final String fDate = date1.toString();    final String duration = managedCursor.getString(duration1);    String type = null;    // Create JSonObject    JSonObject item = new JSonObject();    // add the items to JSonObject    item.put("number", number);    item.put("type2", type2);    item.put("fDate", fDate);    item.put("duration", duration);    // add the JSonObject to JSonArray    jArray.put(item);}managedCursor.close();System.out.println(jArray.toString());
