In the description of how to add a list of options to an AlertDialog the official Android documentation alludes to saving a users preferences with one of the "data storage techniques." The examples assume the AlertDialog has been spawned within an Activity class.
In my case I've created a class that extends ItemizedOverlay. This class overrides the onTap method and uses an AlertDialog to prompt the user to make a multi-choice selection. I would like to capture and persist the selections for each OverlayItem they tap on. That said I am unsure if utilizing an AlertDialog in this manner is the right approach and open to other suggestions.
protected boolean onTap(int index)
{
OverlayItem item = _overlays.get(index);
final CharSequence[] items = { "WiFi", "BlueTooth" };
final boolean[] checked = { false, false };
AlertDialog.Builder builder = new AlertDialog.Builder(_context);
builder.setTitle(item.getTitle());
builder.setMultiChoiceItems(items, checked, new
DialogInterface.OnMultiChoiceClickListener()
{
@Override
public void onClick(DialogInterface dialog, int item,
boolean isChecked)
{
// for now just show that the user touched an option
Toast.makeText(_context, items[item],
Toast.LENGTH_SHORT).show();
}
});
builder.setPositiveButton("Okay", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int id)
{
// should I be examining what was checked here?
dialog.dismiss();
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface dialog, int id)
{
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
return true;
}
