intent用法很靈活，以下列出了intent的一些常用例項，主要包括activity的跳轉及啟動：
intent intent = new intent(activity.main.this, activity2.class);startactivity(intent);
intent intent = new intent(activity.main.this, activity2.class);bundle bundle=new bundle();
bundle.putstring("name", "this is from mainactivity!");
intent.putextras(bundle);
startactivity(intent); startactivityforresult(intent,request_code);
對於資料的獲取可以採用：
bundle bundle=getintent().getextras();string name=bundle.getstring("name");
intent intent=getintent(); bundle bundle=new bundle(); bundle.putstring("name", "this is from activity2!"); intent.putextras(bundle); setresult(result_ok, intent);
注：setresult(int resultcode, intent data);中的引數resultcode的作用是：在上乙個activity的onactivityresult函式中作為第二次判斷用（第一次判斷在startactivityforresult(intent intent, int requestcode);中指定)
@overrideprotected void onactivityresult(int requestcode, int resultcode, intent data) }}
