Dynamically setting links to text in strings.xml - android

I'm trying to make an app with localisation built in, but I want a way that I can create a web link within the text, the URL being defined elsewhere (for ease of maintenance).
So, I have my links in res/values/strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
...
<string name="link1">http://some.link.com</string>
<string name="link2">http://some.link2.com</string>
</resources>
and my localised text in res/values-en-rGB/strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
...
<string name="sampleText">Sample text\nMore text and link1\nMore text and link2.</string>
</resources>
I've not tested this bit, but from the localization section of developer.android.com it says that this approach to reducing content duplication should work, although I'm not sure what folder I should put Italian, for example. Would it be in 'res/values-it-rIT/strings.xml'? Lets assume that I have various other languages too.
I'm looking for a way of taking the base localised 'sampleText' and inserting my html links in, and getting them to work when clicked on. I've tried two approaches so far:
1,
Putting some formatting in the 'sampleText' (%s):
<string name="sampleText">Sample text\nMore text and link1\nMore text and link2.</string>
and then processing the text like this:
TextView tv = (TextView) findViewById(R.id.textHolder);
tv.setText(getResources().getString(R.string.sampleText, getResources().getString(R.string.link1), getResources().getString(R.string.link2)));
But this didn't work when I click on the link, even though the link text is being put in to the correct places.
2, I tried to use Linkify but the regular expression route may be difficult as I'm looking at supporting non-Latin based languages. I tried to put a custom xml tag around the link text and then do something like this:
Pattern wordMatcher = Pattern.compile("<span1>.*</span1>");
String viewURL = "content://" + getResources().getString(R.string.someLink);
Linkify.addLinks(tv, wordMatcher , viewURL );
But this didn't work either.
So, I'd like to know if there's a way of dynamically adding multiple URLs to different sections of the same text which will link to web content?

The problem is your "a href" link tags are within strings.xml and being parsed as tags when strings.xml is parsed, which you don't want. Meaning you need to have it ignore the tags using XML's CDATA:
<string name="sampleText">Sample text <![CDATA[link1]]></string>
And then you can continue with Html.fromHtml() and make it clickable with LinkMovementMethod:
TextView tv = (TextView) findViewById(R.id.textHolder);
tv.setText(Html.fromHtml(getString(R.string.sampleText)));
tv.setMovementMethod(LinkMovementMethod.getInstance());

In your layout set android:autoLink to web
<TextView android:text="#string/text_with_url"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:autoLink="web" />
And in strings.xml just add the URL(s).
<string name="text_with_url">http://stackoverflow.com/ FTW!</string>

Try using Html.fromHtml() to convert the HTML into a Spannable that you put into the TextView. With what you have in #1, I would expect the TextView to show the HTML source, not rendered HTML.

You have to implement
setMovementMethod(LinkMovementMethod.getInstance());
on your Textview

how to superscript in a title in androidplot?

I'm trying to superscript a number in a title in androidplot, like so:
strings file:
<string name="plot_title_3m">stuff per m<sup>3</sup></string>
xml file:
androidPlot.title="#string/plot_title_3m"
but it doesn't superscript at all, the number is normal styling. I've also tried using
<string name="plot_title_3m">stuff per m<sup>3</sup></string>
but no dice, it actually shows the sup tags in the title
also tried this
<string name="plot_title_3m">stuff per m<small><sup>3</sup></small></string>
and actually found out that the 'small' tags don't work either...
You can use HTML tags to achieve this. To be more exact, you need to use Spans on your input text to achieve this look on TextView, but we have a friendly neighborhood helper class that converts some common HTML tags into spans.
E.g.:
((TextView)findViewById(R.id.text)).setText(Html.fromHtml("X<sup>2</sup>"));

Formatting string in xml resource file

I want to display help dialog box in which it has one textview and it loads the content from the String.xml file. Instead of making it one boring paragraphs, I would like to add some formatting to that String.xml For example coloring some sentences, bold..etc. Is there a way I can do that in the xml file within the string?
My xml looks like that
<string name="help_summary">Clicking on button (Summary) will result in ((report))</string>
So I want (Summary) to be red color and ((report)) to be bold.
How can I achieve that?
You can use Html. When you load the string in the textview use:
yourTextView.setText(Html.fromHtml(context.getResources().getString(R.string.help_summary)));
And use html in the string, for example:
<string name="help_summary"><![CDATA[Clicking on button <span style="color:red">Summary</span> will result in <b>report</b>]]></string>
There are some attributes that can be used in string resources without implementing HTML into and or altering your java code. None needed, you CAN do most of what you seem to need in strings.xml
Example:
<string name ="my_string"><i>italics</i><b>bold</b><u>underline</u><font fgcolor="#FFFFFFFF">color</font><small>small text</small></string>
I believe there is a <large/> or <big/> tag as well, amongst a few more.
Edit also, there is \n for a new line. Just include that in your string like so:
<string name="paragraph">Text is one first line \n now text is on next line. \n\n this will appear as an indented paragraph now.</string>
Hope this helps, happy coding!

color string resource for xml layout

<string name="some_text">this is <font fgcolor="#ffff0000">red</font></string>
or
<string name="some_text">this is <font color="#ffff0000">red</font></string>
is not doing it.
I need to call the string in an xml TextView. How do I get it to work? No I don't want to use a horizontal LinearLayout with a bunch of TextViews.
You can't do this. instead of you can set TextView text as HTML like
textview.setText(Html.fromHtml("this is<font color=\"##ffff0000\">red</font>"));
Go to this for more HTML tag support information :html-tags-supported-by-textview
TextView doesn't support entering HTML text directly, though some of the other answers seem to show you how to get a Html object from the String. If you want to format the text within a TextView you need to use Spannable instances to format the sections of text to have different colours, fonts etc. This is only good if you don't already have your text in HTML though, of course.

How to make XML strings bold, underlined etc?

http://docs.fusioncharts.com/charts/contents/Styles/Font.html
I tried this, along with a lot of things but failed to do so.
Here's what I want.
<string name="ss">Bold. Underlined. Italic. Big. Small</string>
I want to format a little bit of the string.
Where it's written bold, I want it to be bold...and same for others.
I tried a lot of tags ...but well nothing worked, and I couldn't find anything on Google or SO.
I know how to do it in a textview, but that's not what I want...
I'm sending some text resource to an activity that shows it...
If I did it with different text views, I'd have to create several of them, a new one for whenever I want bold text, and that's not very elegant.
Is there a way to simple do this in the XML file ? or some other way ?
Try wrapping your marked up text in CDATA tags. For example:
<string name="ss"><![CDATA[<b>Bold.</b> <u>Underlined.</u> <i>Italic.</i> <big>Big.</big> <small>Small</small>]]></string>
And then use Html.fromHtml wherever you're wanting to display it:
Html.fromHtml(getString(R.string.ss))
This problem has been driving me crazy for ages. It's something sooo simple that you just want it to work!!!
Anyway I've found an answer here at http://www.coderzheaven.com/2011/06/19/styling-text-in-android-through-xml/
The key is to load the resource as a CharSequence using getResources().getText(R.string.xxxx) this will retain all the style information and allow you to use inline styling tags.
My mistake was using getString() because when loading your resource getString() will cause the string to lose all its style information.
exemple:
<string name="ss"><font size="15"><b>Parrainage</b></font><u>subscribe</u></string>
b = bold et u = underline .....etc
This is working for me.
<string name="welcome_messages">Hello, %1$s! You have <b>%2$d new messages</b>.</string>
txt.setText(Html.fromHtml(getString(R.string.welcome_messages)));
more details check Official site:
https://developer.android.com/guide/topics/resources/string-resource.html#StylingWithSpannables
in dimens file write:
<dimen name="size_edittext">180dp</dimen>
and in your xml layout or activity call it:
android:#dimen/ size_edittext

Format items coming from a String-Array in XML

Im trying to format items(Bold, new line, italics, etc...) In a string array in an xml file Ive created for the arrays(items.xml). Each Item is going to have a different format and Im trying to figure out a way to format each item. using \n I can get new lines, but can get bolding of text or anything else. How can this be done?
My code to display the items in the array:
Intent launchingIntent = getIntent();
String content = launchingIntent.getData().toString();
TextView viewer = (TextView) findViewById(R.id.tutView);
viewer.setText(content);
setContentView(viewer);
It grabs the item number from a previous activity to display the text in the item in the array.
EDIT: Found the answer. Cant answer it for another 8 hours, so here it is:
I figured out, by searching the Android dev website, which I should have done first, is to use "&lt" before the bold tags, and to use Html.fromHtml(content) and it seems to do exactly what I needed.
Styling with HTML markup
You can add styling to your strings with HTML markup. For example:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="welcome">Welcome to <b>Android</b>!</string>
</resources>
Similar thing can be applied with string array in strings.xml
Supported HTML elements include:
<b> for bold text.
<i> for italic text.
<u> for underline text.
