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]}"; }
