Dialogfragment java.lang.IllegalStateException: Das angegebene Kind hat bereits einen Elternteil. Sie müssen zuerst removeView() für das übergeordnete Element des Kindes aufrufen.

Question

Ich rufe eine Liste in einem Dialogfragment auf, das von einem benutzerdefinierten Adapter geladen wird.

Laden mein Fragment

ProfileListViewHolder.imageButtonMore.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      ProfileDialog ProfileDialogFragment = new ProfileDialog(); 

      ProfileDialogFragment.setStyle(DialogFragment.STYLE_NORMAL, R.style.CustomDialog); 
      android.support.v4.app.FragmentTransaction fragmentManager =((AppCompatActivity)context).getSupportFragmentManager().beginTransaction(); 

      fragmentManager.replace(R.id.drawer_layout,ProfileDialogFragment) .addToBackStack(null).commit(); 

     } 
    }); 

und das ist mein Dialog, die ich verwende

public class ProfileDialog extends android.support.v4.app.DialogFragment { 

private Context context; 

public View profileView; 


@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
} 


public void setTitle(String title) { 
    Dialog dialog = getDialog(); 
    dialog.setTitle(title); 
} 

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

    if (profileView == null) { 
      profileView = inflater.inflate(R.layout.fragment_profile_dialog, container,false); 
    } else { 
     ((ViewGroup) profileView .getParent()).removeView(profileView); 
    } 

    ListView profileListView = (ListView) profileView.findViewById(R.id.lstvSelectedProfile); 


    return profileListView; 
} 

@Override 
public void onStart() { 
    super.onStart(); 
    //addInnerFragment(); 
} 

@Override 
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { 
    super.onViewCreated(view, savedInstanceState); 


} 
@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 
    Dialog dialog = super.onCreateDialog(savedInstanceState); 
    return dialog; 
} 

} 

Answer 1

Sie sind die profileListView statt profileView zurück. Ändern Sie den Code wie folgt,

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     profileView = inflater.inflate(R.layout.fragment_profile_dialog, container, false); 
     ListView profileListView = (ListView) profileView.findViewById(R.id.lstvSelectedProfile); 
     return profileView; 
    } 

Answer 2

Versuchen

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

    profileView = inflater.inflate(R.layout.fragment_profile_dialog, container,false); 

    ListView profileListView = (ListView) profileView.findViewById(R.id.lstvSelectedProfile); 

    return profileView; 
}
