May 12, 2010we have an XML file placed in the res/xml folder containing our preferences.
Is it possible at runtime to add new items to the preferences.
Example:
The user starts the app and the preferences consists of:
America
- New York - Los Angeles - Chicago
Where all the cities are CheckBoxPreferences.
Then the user performs some actions in the application and this triggers that two new cities are added to the preferences:
America
- New York - Los Angeles - Chicago - Seatlle - Washington
Anyone that know if it possible at all and how to do it?

Android :: Color Spinner List Items

Alternatively I would like to disable som list items, but still be able to capture the event when they are chosen.
View 5 Replies View RelatedAndroid :: How To Manage Height Of Spinner Items
Jun 13, 2010I have an android spinner that's populated by a list of strings using an ArrayAdapter and it operates fine, however because of the way the spinner is displayed I'm running into a display height problem with the list items.
At first glance it would seem that the ArrayAdapter can use a single layout for displaying options which leads to the problem I'm having. When displaying the current item in the spinner (when the user is not selecting a new item from the list) the spinner pads the text so that the spinner is a reasonable size for clicking on. However when the user taps on it and brings up the list to select a new item, the list items presented are way to small height-wise. If I use an item layout that presents the list items at a reasonable height, then the spinner itself becomes exorbitantly huge due to it's own padding of the list item.
Any ideas on how I can manage the height of these two item display modes so that effectively they display with the same height value instead of the spinner height being larger than the list item display height?

Android :: Dynamically Adding A View To Activity Layout
Aug 18, 2010I have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).
The book says to fetch the RelativeLayout using findViewById() in my java code then create a new instance of my custom view, then use addView on the RelativeLayout to add the new view.
I'm not getting any errors, but when I click my button to add the new view, nothing is happening (view isn't being added). Do I need to set additional properties on my custom view (layout width, layout height for example) in order for it to be shown?

Android :: Displaying XML-based Layout / Adding Text Dynamically
Sep 12, 2009I have a LinearLayout defined in XML that I want to use repeatedly to display elements of a list. The XML-layout looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/background"
android:paddingBottom="5px">
<TextView
android:id="@+id/destination"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="22dp"
android:text="@string/test_destination"
android:paddingLeft="5px"/>
<TextView
android:id="@+id/date"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:text="@string/test_date"
android:paddingLeft="5px"/>

I gather information about certain events from a webpage, and then I want to display all events in a list using the above layout for each event. My current approach is to have a LinearLayout as parent and then adding each event as a row.
Problem number one is to add the layout to each event (the number of events is varying). I.e., I want to dynamically inflate this layout for each event. I also don't want the text to be hard coded into the layout (as above) but added at runtime. I don't know how to do this. I have tried something like the following without any success.
LinearLayout eventView = (LinearLayout) findViewById(R.layout.event);
parentView.addView(eventView);
Problem number two is then to add these layouts to the parent view group and display it on the screen. When I try to do this using parent.addView(child), the program crashes at runtime and I can't figure out why.
It's kind of hard to describe the specific problem, since I'm new to GUI-programming on Android and I'm sort of programming by trial and error right now. Anyway, if you are able to help me with some of the problems it would be greatly appreciated. Linus
EDIT:
The problem now is adding text dynamically to the TextViews. I try this:
TextView dest = (TextView) findViewById(R.id.destination);dest.setText("myText");
only to discover that dest is null. Any ideas why and how to fix this?
EDIT 2:
I have narrowed the problem even more, but I really don't understand its nature. This is the trouble-method: Code...
it somehow works (even though the events are displayed in reverse order). Anyone knows what's going on here?

Feb 4, 2010When I add a new item to my ItemizedOverlay the onTap display I have set appears X times, where X is equal to the number of items that I added. So for example, if I add one item and tap it, it the onTap method gets called once, and in the LogCat I get:

If I add a second item and click ANY of the other items, the onTap method gets called twice and I get the following in LogCat:

If I add a third item and click ANY of the other items, the onTap method gets called three times and I get the following in LogCat:

Any idea why this would occur? I'm running into issues with it affecting other things like removal of items.
