通过bindservice调用服务内部方法

1.在服务内部定义一个方法

public void banzheng(int money) { if (money < 1000) { Toast.makeText(getApplicationContext(), "太少了", 1).show(); } else if (money > 1000) { Toast.makeText(getApplicationContext(), "太多了", 1).show(); } }

2.在服务的内容定义一个中间人对象

public class MyBinder extends Binder { public void callBanZheng(int money) { banzheng(money); } }

3.把定义的中间人对象放在onBind内并返回

@Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub return new MyBinder(); }

4.在acivity的oncreate方法内调用bindService

Intent intent = new Intent(this, BanZhengService.class); conn = new MyConnection(); bindService(intent, conn, BIND_AUTO_CREATE);

5.拿到中间价对象，就可以调到服务的电话

public class MyConnection implements ServiceConnection { @Override public void onServiceConnected(ComponentName name, IBinder service) { // TODO Auto-generated method stub binder = (MyBinder) service; } @Override public void onServiceDisconnected(ComponentName name) { // TODO Auto-generated method stub } }

6.在 onDestroy方法内解绑

@Override protected void onDestroy() { // TODO Auto-generated method stub unbindService(conn); super.onDestroy(); }
