数据源fragment：

SPMainActivity activity=(SPMainActivity)getActivity();activity.fragTOFragsendMessage(search);//调用activity的方法，参数是传递的值。

activity：

public void fragTOFragsendMessage(String search){   Message msg = new Message();   Bundle bundle = new Bundle();   bundle.putString("search", search);   msg.obj = bundle;   msg.what = 111;   mHandler.sendMessage(msg);}

public void setHandler(Handler handler) {   mHandler = handler;}

接收数据的fragment：

private SPMainActivity mActivity;

@Overridepublic void onAttach(Activity activity) {    super.onAttach(activity);    mActivity = (SPMainActivity) activity;    mActivity.setHandler(mHandler);}

private Handler mHandler = new Handler() {    @Override    public void handleMessage(Message msg) {        switch (msg.what) {            case 111:                Bundle bundle=(Bundle)(msg.obj);                search=bundle.getString("search");                refreshData();                break;            default:                break;        }    }};
    mActivity = (SPMainActivity) activity;    mActivity.setHandler(mHandler);}
