android关于fragment的构造函数用法建议

Avoid non-default constructors in fragments: use a default constructor plus Fragment#setArguments(Bundle) instead:

public static final GridFragment newInstance(String tabId){

    GridFragment f = new GridFragment();

    Bundle bdl = new Bundle(2);

    bdl.putString(TAB_ID, tabId);

    f.setArguments(bdl);

    return f;

}

@Override

public void onCreate(Bundle savedInstanceState) {

    String tabId = getArguments().getString(TAB_ID);

    }

@SuppressLint("ValidFragment")

public PlaceDialogFragment(Place place, DisplayMetrics dm){

        super();

        this.mPlace = place;

        this.mMetrics = dm;

    }
