In an Android application I am writing, the styling for my various TextView elements is defined in an xml resource. I would like enable the user to change certain styles such as android:typeface using a PreferenceActivity. Is there a way to modify a style resource programmatically such that all associated widgets will update correctly? If not, must I manually select all widgets by id and change their styling?

Given a widget and a int that references a style (defined in my res/ values/style.xml), what is the 'correct' way to programmatically apply the style to the widget?
Up until now I've been hacking this by...
CODE:..................
For Style and Thems defination, CSS is considered to be a better standard...(as it has seen many revisions and widely used already in the web areas).. Any reason, why Android using XML approach as opposed to CSS.. Are there any plans of support of CSS too in future..
View 5 Replies View RelatedI want to enable different themes in my app. Some elements need "special" variations, like, for example, a headline TextView. Lets say for the example, in theme A, I want the headline yellow on black, in theme B red on white, while the default TextView uses black on white and vice versa.
Now, I can style the default TextView pretty easy by using <item name="android:textViewStyle"> with a different TextView style in each Theme style.
For example:
CODE:............
But how can I do it with the headline? As far as I know, I can use style="..." in the layout XML. But there, I can only use an item style like "headlineForBlack", which would ignore the current theme, while I'd rather need something like "style 'headline' for the current theme".
I have defined some attributes in my view and I can assign them like:
CODE:................
This works. But when I want to do the same thing with styles.xml:
CODE:.................
I get "No resource found that matches the given name".
Where can I find default styles for my widgets? Let me give you an example. In the Contacts application, when adding a new contact, at the very bottom there are two buttons that have a particular background. I have traced that to here: http://android.git.kernel.org/?p=platform/packages/apps/Contacts.git;... and it would seem that that background is achieved by using style="@android:style/ButtonBar" on a LinearLayout. From what I understand, this is a system-wide theme default for button bars. However, what I am searching for is not a ButtonBar, but similar, so I tried searching for this ButtonBar in the documentation, hoping to find other similar styles I could use. I *thought* I would find it in R.style:[url]

View 3 Replies View RelatedI'm supposed to develop an app which behave like that: The User starts the app and can select between different configurations. Depending on the selection there are different colors, drawables and strings (e.g. urls for webservice-calls) to display. All the code-stuff is the same.
My first intention to do so was themes.... - is it possible to include somehow strings in themes? - what shall I do with styles which are referenced in some layout-xml (which are the same for all configs) and should use different colors. can't define colors or styles multiple times and don't want to change that manually (when user selects by code).

So I have the basics down... I can create a UI with the XML, I can show it and change the screen to another UI (another XML file) but how do I add to the UI?
Hard to explain...
Say I have a header (just 2 textviews) that will remain at the top and below that is a search box and button (main.xml). The user searches and I have it display the search UI (search.xml). This UI will have the same header (2 textviews) and below it will have several textviews each one containing a search result... Kinda like if you search for an app in the market. There's no way of telling how many results would be returned so I figured I would have to create each textview on the fly within the .java file. I'm not sure how to do this. Most likely would require a loop of some sort, but whats the syntax to create a new textview and display it right below the one above it? I'm working with linear here so I would assume just creating a new textview it will by default go to the next one down which is what I want.
Also, say I have 30 results... How do I get those to scroll but leave the 2 textview header in place? Would I create a ScrollView and put the new TextViews in that?
Is there a way to change the Alert Dialog style, like background and font color using something like

Do you know if it's possible to apply a theme or a style on a OptionMenu ? I don't find tag in R.style or R.styleable to customize it and apply a theme.
View 3 Replies View RelatedI've got a text style defined in styles.xml. I'm trying to reference it from a layout. When I reference from the layout, it causes an exception upon inflation. If I use the style from java code, it works fine. Setting the individual styles on the TextView works fine too:

Im trying to figure out how to use Styles. It seems easy, but its not working.
First, here is my XML for the Button:
<Button style="@style/Btest" android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Some text"></Button>
And here is the values/styles.xml:
CODE:...........
Its not working at all. If I dont use Style and just add the style directly in the XML for the Button - no problem.
In the ApiDemos, there is a view example called Gallery1 which declares a custom style in attrs.xml.I want to do the same thing for my widgets, but using a different namespace. However, as soon as I replace the android: namespace with something else,Unable to find attribute? Why does it look for an attribute I am about to declare? Isn't the point of this file to be able to name your own custom attributes?It's interesting to note that it works if you do not supply a custom namespace, but just an attribute name.

View 3 Replies View RelatedI was wondering if its possible to set multiple styles for different pieces of text inside a TextView. For instance, I am setting the text as follows:
CODE:...........................
Now, is it possible to have a different style for each text element? I mean bold for line1, normal for word1 and so on...
I found this http://developer.android.com/guide/appendix/faq/commontasks.html#selectingtext:
Get our EditText object. EditText vw = (EditText)findViewById(R.id.text);
Set the EditText's text. vw.setText("Italic, highlighted, bold.");
If this were just a TextView, we could do: vw.setText("Italic, highlighted, bold.", TextView.BufferType.SPANNABLE); to force it to use Spannable storage so styles can be attached. Or we could specify that in the XML.
Get the EditText's internal text storage. Spannable str = vw.getText();
Create our span sections, and assign a format to each.
CODE:............................
But it uses position numbers inside the text. Is there a cleaner way to do this?
I am writing an application that will run on 2.0 and above. Now, I am thinking of adding the Data backup feature to the application.

If I do not set the property FillAfter to true then the image in my view, that I use RotateAnimation to animate, returns to the initial position after the animation is done. My problem is that when I set fillafter to true when I later set the image on my imageview to another image than the one I animated some kind of transformation is applied to that image also.

I am looking for some answers from some of the experts here. I have a project in mind that I want to start. It is about using HTC's Touch HD phone as a device in a museum with rich media/video about the art and the artists on it. Besides the videos and animation, I also want to show some content from a web browser. Now my biggestest issue. I do not want that the museum guest who pick up the phone for the tour get to see the standard Android user interface. Is there a way to develop a new user interface that would start up directly once the phone is turned on? It should then automatically start the app with the museum infos. Later I may want to add some GPS functions and even sms and photo taking, etc....
What do you think, how flexible is Android to allow that?

View 3 Replies View RelatedCurrently my ListView is filling up with the given String[] but I wanted to alternate some styles on the ListView items. Something weird is happening (I'm surely missing something obvious); The ListView Index is not fixed and the styles are not alternating as supposed. My Code is the following:

In my Android application I've hidden the default title bar, introduced a TabView and added my own titlebar under that TabView's tabs. At the moment, I'm using the ?android:attr/windowTitleStyle style which makes my new titlebar look gray and gradient. It looks pretty good, but my screens are looking pretty grayscale. I'd like to spice things up a bit by making this titlebar a different color gradient.
What am I looking at here? Creating my own image and using it? The ?android:attr/windowTitleStyle style seems to expand depending on the height of your custom titlebar; so I'm not sure it's actually a single image.
I've attempted to throw a LinearLayout over it with a bit of translucency (ex: making the color #800000FF), but the gradient style I have behind this LinearLayout disappears.
Update:
Per my answer down below, I've figured out that I can create an XML file that defines a gradient and use that. It works fine inside a LinearLayout (titlebar_gradient) I have on my layout. However, it is not working on the outer-most LinearLayout (background_gradient). Could someone tell me why? As I understand it, the ListView should be transparent...
