У меня есть DialogFragment, который имеет представление списка с CheckedTextView и флажок вверху, чтобы проверить и снять отметку со всех элементов в представлении списка. Я пытаюсь установить для состояния CheckedTextView значение Checked/Unchecked в зависимости от состояния флажка CheckAll. Но я не могу соответствующим образом обновить представление, используя notifyDataSetChanged.

CheckBox checkAll;
ListView categoriesListView;

String[] categories = new String[] { "Hill Station", "Beach", "Historic",
"Wild Life", "Waterfall", "River", "Archeology", "Hill Station",
"Beach", "Historic", "Wild Life", "Waterfall", "River",
"Archeology" };
Boolean[] categories_state = new Boolean[] { true, false, true, true, true,
true, false, true, false, true, true, true, true, false };
public static CategoriesDialogFragment newInstance() {
CategoriesDialogFragment frag = new CategoriesDialogFragment();
Bundle args = new Bundle();
frag.setArguments(args);
return frag;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Dialog dialog = new Dialog(MainActivity.context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dialog_categories);
categoriesListView = (ListView) dialog
.findViewById(R.id.listViewDialog);
List<Category> theCategories = new ArrayList<Category>();
for (int i = 0; i < categories.length; i++) {
Boolean flag;
Category pl = new Category(categories[i], categories_state[i]);
theCategories.add(pl);
}
// categoriesListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
adapter = new CategoriesListAdapter(MainActivity.context,
R.layout.dialog_list_item_category, theCategories);
categoriesListView.setAdapter(adapter);
// List View Item Click Listener
categoriesListView
.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
CategoriesListAdapter adapter = (CategoriesListAdapter) parent
.getAdapter();
Category c = (Category) adapter.getItem(position);
c.setChecked(!c.getChecked());
adapter.notifyDataSetChanged();
}
});
// CheckAll CheckBox

checkAll.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override

boolean isChecked) {
Toast.makeText(MainActivity.context, "Check",
Toast.LENGTH_SHORT).show();
for (int i = 0; i < adapter.getCount(); i++) {
categoriesListView.setItemChecked(i, isChecked);
Log.i("Nomad", isChecked + " isChecked " + i);
