Question

I want to setup a button, that when clicked on will pull data from my database and fill a list (like when using a spinner). I’ve used popup menus before but haven’t figured out a way to make them float (anyone know how to make the size a float and not pix). Is there a way to have a button pull up a list like a spinner or is it just better for me to change my ui to have the spinner instead of using an clickable image button?

You can create a dialog that takes an adapter of your items

YourCustomAdapter adapter = new YourCustomAdapter(/**whatever args you need to get your content**/);
int selectedItem = -1; //somehow get your previously selected choice
Builder builder = new Builder(context);
builder.setSingleChoiceItems(adapter, selectedItem, new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which)
    {
         //handle the item you clicked here

    }
};
builder.setTitle("Select Attachments").setCancelable(true);

Dialog dialog = builder.create();

Note that if you need to select multiple items there are methods for multiple choice items.
builder.setMultipleChoice…
