在Android中停止服务

在这里，我尝试了简单的服务程序。启动服务可以正常工作并生成Toast，但停止服务则不能。此简单服务的代码如下：

public class MailService extends Service {
    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }
    public void onCreate(){
        super.onCreate();
        Toast.makeText(this, "Service Started", Toast.LENGTH_SHORT).show();
    }
    public void onDestroyed(){
        Toast.makeText(this, "Service Destroyed", Toast.LENGTH_SHORT).show();
        super.onDestroy();
    }
}

调用此服务的活动的代码如下：

public class ServiceTest extends Activity{
    private Button start,stop;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.service_test);
        start=(Button)findViewById(R.id.btnStart);
        stop=(Button)findViewById(R.id.btnStop);
        start.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                startService(new Intent(ServiceTest.this,MailService.class));
            }
        });
        stop.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                stopService(new Intent(ServiceTest.this,MailService.class));
            }
        });
    }
}
