Android :: Multiple Styles Inside A TextView?
Oct 7, 2009
I 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?

Is it possible to display Css style tags in a text view..? The method Html.fromhtml() converts only html tags to a spanned string but not the Css styles

I'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).

I have a Spinner with an ArrayAdapter that feeds Values into it. The layout for this views looks something like this:
CODE:.................
The Problem is that the text is to long for the view and the result is a very very ugly spinner. As can be seen in the screenshot:
I tried to pass the Id of my own TextView into the Adapter but everytime the spinner should be shown I get an Exception that the Id I supplied is not valid:
CODE:........................
Where do I have to define the TextView? In a separate xml file? With a surrounding viewgroup?
It would help me a lot if I could see an example of the adapter initialization and the textview definition?

I've got a ListView where each item in the list is contains several controls. One of the items is a checkbox, and I can check/uncheck it without problems. The other items are some TextViews and a WebView. I've got autoLink turned on and linksClickable turned on, but I can't get links to fire up the browser when I click on them. This applies to both TextView and WebView. I've tried changing the parent to a GridView instead of a ListView, playing with setFocusable(), and all that, but to no avail.
Is it even possible to have interaction on the TextView-based elements of a row in a ListView? It seems like that *should* be possible, but I've been banging my head against this problem for a few weeks with no progress. What's the secret?

I'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.
Right now I'm essentially using the Hello ListView code to create my ListView.
(In constructor)
CODE:...........
Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:
CODE:.............
This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.

I have a ListView with custom ArrayAdapter. Each of the row in this ListView has an icon and some text. These icons are downloaded in background,cached and then using a callback, substituted in their respective ImageViews. The logic to get a thumbnail from cache or download is triggered every time getView() runs.

I have read the Android UI trick 2 on Android developers, which tells people how to include a layout in another layout file multiple times, and give these included layouts different id. However, the sample here is overwriting the layout id, not the id of the views IN this layout. For example, if the workspace_screen.xml looks like this: And I include it three times in another layout file. Do I end up with three TextViews with id firstText, and another three with secondText? Isn't there an id collision? And how do I find the secondText TextView in the third included layout with findViewById? What should I input in the findViewById method?

I am using a textview to display some text and I would like different parts of the text to be shown in different colours, e.g. first half of the text in red, second in blue. I cant seem to find a way of doing this. I have heard of using Html.fromHtml() but I am not exactly sure how to do it this way.

I created a simple Java function to truncate a string to be displayed in my list view. I am displaying a news title and below this a news summary. I would like to have the same behavior as the image below. Currently, i am truncating the news title with 45 chars and then appending "..." at the end of it. However, when I change the orientation to landscape, the title could appear without being truncated. I don't think the app below truncates the news title, but it keeps the title in a single line and automatically "truncates". How can I achieve this behavior in my app?

I'm looking to clean up my home screens a little and would like to be able to create one on-screen folder or widget that can hold multiple other widgets for quick access and easy launch. Specifically, I have quite a few ColorNote files that I need quick access too, but don't necessarily want clogging up my home screen. I'm hoping there's something out there - either a folder organizer, launcher, or widget that can do this for me.
I currently use GoLauncher and FolderOrganizer on my SG Note.

If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.
Here is the code:..............
Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):
So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):
As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.
Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg

I've been a couple of days trying to solve this thing but I can'f figure it out.The problem is, simple activity, with simple layout, ScrollView -> LinearLayout -> and a lot of buttons inside the layout (within the scroll content). Everything works just fine but one tricky thing. When I click a button let's say at the top of the scroll content and inmediatelly I scroll down to the bottom of the content and I click other button there, nothing happens until I click a second time and all come to normal again.This can be reproduced anytime and it's code independent (i've tried more than 20 scenarios). I've not much experience in android yet but looks like the scroll listener stops the onclick listener or something like that.

So I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?

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..

I 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".
