这是我的json数组.
This my json array.
[
{
"type":"select",
"label":"Select",
"className":"form-control",

JSONArray js = null;
try {
js = new JSONArray(json);
} catch (JSONException e) {
e.printStackTrace();
}
JSONObject obj = null;
for (int i = 0; i < js.length(); i++) {
try {
obj = js.getJSONObject(i);
} catch (JSONException e) {
e.printStackTrace();
}
try {
type = obj.getString("type");
} catch (JSONException e) {
type = null;
}
System.out.println("Type : " + type);
try {
JSONArray jContent = obj.getJSONArray("values");
System.out.println(jContent.toString());
for (int iterate = 0; iterate < jContent.length(); iterate++) {
JSONObject inner = jContent.getJSONObject(iterate);
String inner_label = (String) inner.get("label");
System.out.println(inner_label);
String val = (String) inner.get("value");
boolean sel;
try {
sel = (boolean) inner.get("selected");
} catch (JSONException j) {
sel = false;
}
System.out.print(inner_label);
System.out.print(" " + val);
System.out.println(" " + sel);
}
} catch (JSONException e) {
System.out.println("There is some error");

我能够获取所有其他对象的值，但我无法读取values数组.我已经为它编写了代码，但它直接转到catch块，并显示错误消息有一些错误".谢谢您的帮助.
I am able to get all other objects values I am unable to read the values array. I have written the code for it but its directly going to the catch block printing the error message "There is some error". Thnaks for the help.
推荐答案
已解决...值不是一个数组，而是一个对象....所以这就是我所做的.奏效了.
Solved...Values was not an array it was an object....So here's what I did. It worked.
try {
String j2 = obj.getString("values");
JSONArray jContent = new JSONArray(j2);
for (int iterate = 0; iterate < jContent.length(); iterate++) {
JSONObject inner = jContent.getJSONObject(iterate);
String inner_label = (String) inner.get("label");
System.out.println(inner_label);
String val = (String) inner.get("value");
boolean sel;
try {
sel = (boolean) inner.get("selected");
} catch (JSONException j) {
sel = false;
}
System.out.print(inner_label);
System.out.print(" " + val);
System.out.println(" " + sel);
}
