Question

想照着书上敲个状态栏通知， getSystemService();方法报错 它必须在activity中 但我的按钮在fragment中啊

public static class PlaceholderFragment extends Fragment {
private Button button;
private TextView tv;
public PlaceholderFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,
false);
tv=(TextView)rootView.findViewById(R.id.dd);
button=(Button)rootView.findViewById(R.id.ss);
button.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
//获取通知管理器
NotificationManager mNotificationManager=(NotificationManager)getSystemService(NOTIFICATION_SERVICE);

}

});
像很多这种以前是直接写在activity中 现在控件放fragment中了代码很容易出错啊 求高手指导啊

出什么错，你getActivity().getSystemService就好了。
