The use of Jsonobject and Jsonarray Jsonobject contains Jsonarray

A lot of people use json-lib, to use so many libraries is very troublesome Ah, direct eclipse inside with Android's own JSON is good.

It's simple, I'll put the code down.

Import Org.json.JSONArray;
Import org.json.JSONException;
Import Org.json.JSONObject;

Look, this is a self-bringing JSON.

Jsonobject param = new Jsonobject ();
for (int j = 0; J < Postparams.length; J + +) {
//This is the addition of Jsonarray postparams[j].values is specified by a arraylist<string> that is groupids. The red is the list I made in front of me.

for (Alarmgroupbean Chen:alarmgroupbeans) {

if ( Chen.getchecked ()) {
Groupids.add (Chen.getuid ());
}
}
< /span>param.put (postparams[j].name, 
new Jsonarray (Postparams[j]. values));
log.v ("Czyczy", postparams[j].name+ "zzzz" +postparams[j].values+ "CCCCCC ");
}
//This is a generic string key-value pair
{ param.put (postparams[j].name, 
Span style= "White-space:pre" > Postparams[j].value);
log.v ("Czyczy", postparams[j].name+ "zzzz" +postparams[j].value+ "CCCCCC" );
}

LOG.V ("Czyczy", param.tostring ());

The use of Jsonobject and Jsonarray

Introduction of JAR Package

To enable the program to run, the Json-lib package must be introduced, and the Json-lib package relies on the following jar packages:

1.commons-lang.jar

2.commons-beanutils.jar

3.commons-collections.jar

4.commons-logging.jar

5.ezmorph.jar

6.json-lib-2.2.2-jdk15.jar

Second, Jsonobject Object Use

The Json-lib package is a Beans,collections,maps,java arrays and XML and JSON transforms each other's packages. In this example, we will use the Jsonobject class to create the Jsonobject object, and then we print the values of those objects. In order to use the Jsonobject object, we will introduce the "Net.sf.json" package. To add elements to an object, we use the put () method.

Package Com.hwy;

Import Net.sf.json.JSONArray;
Import Net.sf.json.JSONObject;

public class Jsonobjectsample {

Create a Jsonobject object
private static Jsonobject Createjsonobject () {
Jsonobject jsonobject = new Jsonobject ();
Jsonobject.put ("username", "Huangwuyi");
Jsonobject.put ("Sex", "male");
Jsonobject.put ("QQ", "999999999");
Jsonobject.put ("Min.score", New Integer (99));
Jsonobject.put ("nickname", "Mood in the Dream");
return jsonobject;
}
public static void Main (string[] args) {
Jsonobject jsonobject = Jsonobjectsample.createjsonobject ();
Output Jsonobject Object
System.out.println ("jsonobject==>" +jsonobject);

Interpreting the type of the output object
Boolean IsArray = Jsonobject.isarray ();
Boolean isEmpty = Jsonobject.isempty ();
Boolean isnullobject = Jsonobject.isnullobject ();
System.out.println ("IsArray:" +isarray+ "IsEmpty:" +isempty+ "Isnullobject:" +isnullobject ");

Add Property
Jsonobject.element ("Address", "Xiamen, Fujian Province");
System.out.println ("Object ==> after adding a property" +jsonobject);

Returns a Jsonarray object
Jsonarray Jsonarray = new Jsonarray ();
Jsonarray.add (0, "This is a Jsonarray value");
Jsonarray.add (1, "another Jsonarray value");
Jsonobject.element ("Jsonarray", Jsonarray);
Jsonarray array = Jsonobject.getjsonarray ("Jsonarray");
System.out.println ("Returns a Jsonarray object:" +array);
Value after adding Jsonarray
{"username": "Huangwuyi", "Sex": "Male", "QQ": "999999999", "Min.score": "The Heart of the Dream", "Address": "Xiamen, Fujian province", " Jsonarray ": [" This is a Jsonarray value "," another Jsonarray value "]}
SYSTEM.OUT.PRINTLN ("result =" +jsonobject);

Returns a string based on key
String username = jsonobject.getstring ("username");
System.out.println ("username==>" +username);

Convert characters to Jsonobject
String temp=jsonobject.tostring ();
Jsonobject object = jsonobject.fromobject (temp);
Return value after conversion based on key
System.out.println ("qq=" +object.get ("QQ"));

}

}
