Tri ListView dans ListFragment
Bonsoir ,
J'ai crée un spinner qui permet de choisir le type de tri de la listview contenue dans un listfragment .
Cependant lorsque je choisis un tri , la listview ne change pas... Je ne comprends pas pourquoi .
voici mon code :
Pour mon spinner :
Code:
1
2
3
4
5
6

| public void addListenerOnButton() {
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(adapterView.getContext(),
"OnItemClickListener : " + adapterView.getItemAtPosition(i).toString(),
Toast.LENGTH_SHORT).show();
switch (i)
{
case 0:
listFragment.sort(SortType.AlphaTitre);
break;
case 1:
listFragment.sort(SortType.AlphaDesc);
break;
case 2:
listFragment.sort(SortType.Importance);
break;
case 3:
listFragment.sort(SortType.DateCreation);
break;
case 4:
listFragment.sort(SortType.DateAlarme);
break;
}
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
} |
Dans le listfragment :
Code:
1
2
3
| public void sort(SortType type){
adapter.sort(new MonComparator(type));
} |
