我想在下面的代码中刷新或调用onCreateView.

我有一个上下文来删除一个Item,之后我想用新的Item刷新片段.

谢谢！

public class ItemDetailFragmentBlackBoard extends Fragment {

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {

....

return rootView;

}

}

/** Menu on LongClick */

@Override

public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo)

{

super.onCreateContextMenu(menu, v, menuInfo);

menu.setHeaderTitle("Context Menu");

menu.add(0, v.getId(), 0, "Delete");

}

@Override

public boolean onContextItemSelected(MenuItem item) {

if(item.getTitle()=="Delete"){

String status="";

AdapterContextMenuInfo info = (AdapterContextMenuInfo)item.getMenuInfo();

int posizione = info.position;

String[] messaggioDaCancellare= S.getMessaggiInfo().get(posizione);

try{

JSONObject del =ProxyUtils.proxyCall("deleteMessage",messaggioDaCancellare[4]);

status=del.getString("status");

} catch (Exception e) {

Log.i("Eccezione", e.toString());

}

Activity activity= getActivity();

if(status.equals("OK")){

**HERE......I would like to refresh my fragment o recall onCreateView method...**

Toast.makeText(activity, "Delete avvenuta", Toast.LENGTH_SHORT).show();

}else

Toast.makeText(activity, "Delete non riuscita", Toast.LENGTH_SHORT).show();

} else {return false;}

return true;

}

解决方法:

最好在onCreateView函数中定义一个类似简单的linearLayout(称之为屏幕)的viewGroup,并将其填入init()之类的函数中.每次要重新创建视图时,只需删除所有linearLayout的子节点并调用init().

你做得很好,但它比我简单的解决方案更贵.
