Intent intent=new Intent(context,MyService.class);

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.button1:
intent.putExtra("date", "we are friend !");
startService(intent);
break;
case R.id.button2:
stopService(intent);
break;
default:
break;
}
}

public class MyService extends Service{
private boolean running=false;
private String date="这是默认信息";
int i=0;
public MyService() {

}

@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// TODO Auto-generated method stub

date=intent.getStringExtra("date");

return super.onStartCommand(intent, flags, startId);
}
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
running=true;
new Thread(){
@Override
public void run() {
// TODO Auto-generated method stub
super.run();
while(running){
Log.i("TAG", date+i);
if(i==20){
stopSelf();
}
try {
sleep(1000);
i++;
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}}.start();
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
running=false;
}
}
