尝试public class ScrollFragment extends Fragment {
private ObservableScrollView mScrollView;
private String mString;
public static ScrollFragment newInstance(String string) {
ScrollFragment scrollFragment = new ScrollFragment();
Bundle args = new Bundle();
args.putString("stringKey", string);
scrollFragment.setArguments(args);
return scrollFragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mString = getArguments().getString("stringKey");
}
...
}
