I have a ListFragment, where I add a CursorAdapter to my ListView, and I
want to be able to click several rows, to use contextual action bar. I use
SherlockActionbar, and it works fine, when I use a simpleArrayAdapter. But
when I switch to CursorAdapter, it breaks. I cannot select multiple rows,
only one. Any idea why it might happen?
In onActivityCreated I set up the list:
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mActionMode = null;
mListView = getListView();
FinTracDatabase database = mDatabaseProvider.get();
Cursor cursor = database.getTransactionCursor(false);
mCursorAdapter = new TransactionListAdapter(getSherlockActivity(),
cursor);
mListView.setAdapter(mCursorAdapter);
mListView.setItemsCanFocus(false);
mListView.setOnItemClickListener(this);
mListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
This is my Adapter:
private class TransactionListAdapter extends CursorAdapter {
public TransactionListAdapter(Context context, Cursor cursor) {
super(context, cursor, 0);
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
bindToExistingView(view, cursor);
}
private void bindToExistingView(View view, Cursor cursor) {
CheckedTextView amountView = (CheckedTextView) view;
amountView.setText(cursor.getString(cursor.getColumnIndex(Transactions.TITLE)));
}
@Override
public View newView(Context arg0, Cursor arg1, ViewGroup arg2) {
LayoutInflater layoutInflater =
getSherlockActivity().getLayoutInflater();
View view =
layoutInflater.inflate(android.R.layout.simple_list_item_multiple_choice,
arg2, false);
bindToExistingView(view, arg1);
return view;
}
}
And finally the onClickListener:
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long
arg3) {
SparseBooleanArray checked = mListView.getCheckedItemPositions();
boolean hasCheckedElement = true;
for (int i = 0; i < checked.size() && !hasCheckedElement; i++) {
hasCheckedElement = checked.valueAt(i);
}
if (hasCheckedElement) {
if (mActionMode == null) {
mActionMode = getSherlockActivity().startActionMode(new
SelectingActionMode());
}
} else {
if (mActionMode != null) {
mActionMode.finish();
}
}
}
If I switch my Adapter to a simple ArrayAdapter, it works fine.
new
ArrayAdapter<String>(this,android.R.layout.simple_list_item_multiple_choice,
new String[]{"A", "B", "C"})
I am hopeless, and I have no idea, why this is happening.
