Android中生成、使用Json数据实例
1、Json的制作
packagecom.example.usingjson2;
importorg.json.JSONException;
importorg.json.JSONObject;
importandroid.os.Bundle;
importandroid.app.Activity;
publicclassMainActivityextendsActivity{
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
System.out.println("\"HelloWorld\"");
JSONObjectobject=newJSONObject();
try{
object.put("one","yu");
object.put("two","xi");
object.put("three","kuo");
object.put("four","hi");
System.out.println(object);
}catch(JSONExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
}
}
2、Json的使用
（1）首先在当前包中创建新的class
packagecom.example.useingjson;
publicclassData{ publicstaticfinalStringjsonStr="{'arr':[1,2,3,4],'dat':[yu,xi,kuo]}"; }
