关键代码

Timer timer=new Timer();timer.schedule(new TimerTask() {@Overridepublic void run() {Looper.prepare();// TODO Auto-generated method stubToast.makeText(getApplicationContext(), "您的账户已经刷新.", Toast.LENGTH_SHORT).show();Looper.loop(); //codes after this will not be excuted.}}, 5000);

 Looper.prepare()和 Looper.loop()的位置很重要。Looper.loop()后的代码是不会被执行的来。
