Android cursorloader not updating Smart phonesexmate 2014
Here is a working example tested for Android 2.3, and 4.0 (it uses nothing in the compatibility library, so it should be fine for awhile) Since it's a decorator, it should be easy to retrofit existing code and it works fine with is correct.) Spinner does not support multiple view types Code notes: 2 constructors This allows you to use a standard prompt or define your own 'nothing selected' as the first row, or both, or none. */ public class Nothing Selected Spinner Adapter implements Spinner Adapter, List Adapter I know this question has lot of Answer but I found the simplest and easiest way to do.(Note: Some themes show a Drop Down for a Spinner instead of a dialog. This solution is independent of API level ,it will works for all API level.Take a look at the iosched app for a general purpose solution to adding an element to the top of a list.In particular, if you are using a Cursor Adapter, look at Tracks which extends that definition to provide a "set Has All Item" method and associated code to manage the list count to deal with the extra item at the top.
To me the ideal solution would provide the “Select One” (or whatever initial text) when the spinner is first displayed. In my case was only the first one, the rest i leave the original Refer to one of the above answers: https://stackoverflow.com/a/23005376/1312796 I added my code to fix a little bug. Would you like to answer one of these unanswered questions instead?
The Dropdown doesn't normally show the prompt) You define a layout to 'look' like a prompt, for example, grayed out... Idea is to set the last item of spinner as default one.(); objects.add("India"); objects.add("Pakistan"); objects.add("China"); // add hint as last item objects.add("Select Country"); Hint Adapter adapter = new Hint Adapter(context, objects, android.
Using a standard prompt (notice that nothing is selected): Or with a prompt and something dynamic (could have had no prompt also): Usage in above example adapter = Array Adapter.create From Resource(this, R.array.planets_array, android. R.layout.simple_spinner_item); Drop Down View Resource(android. R.layout.simple_spinner_dropdown_item); Spinner spinner Film Type = (Spinner) find View By Id(spinner); Adapter(adapter); // show hint Selection(Count()); (activity, android.
I've tried several things (gravity, padding, margin, etc.) and none worked reliably across devices, so I'm going to opt for a different solution.
with one that presents a 'Select Option...' View initially for the Spinner to display with nothing selected. Spinner Adapter; /** * Decorator Adapter to allow a Spinner to show a 'Nothing Selected...' initially * displayed instead of the first choice in the Adapter.
