/**

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public class WexinFragment extends Fragment {

    public WexinFragment() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
//界面对象化
            return inflater.inflate(R.layout.wexin_01,container,false);
    }
}
