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>"));

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!
Hy! I am working on my Android app and I want to format text so that my TextView shows this text on CONTACT US to look EXACTLY like on that website, but I dont know how to format it in strings.xml file. I have tried with basic HTML formatting putting <br> tag for new row and <a> tag for email adresses and web site, but nothing change. How to format it ? Can so large strings be saved into strings.xml ?

You can use \n for new lines.
Further, you can use Html.fromHtml to create a Spanned that would have basic formatting - bold, italic, links, etc.
You would then need to override the movement method to actually make links operational:
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setLinksClickable(true);
You can use HTML tags, like <br> and <a>, by using:
yourTextView.setText(Html.fromHtml(getString(R.string.your_string)));
Make sure you properly escape any special characters in your strings.xml.

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)));

in dimens file write:
<dimen name="size_edittext">180dp</dimen>
and in your xml layout or activity call it:
android:#dimen/ size_edittext
I am parsing data from an XML file which has subscript and superscript characters in them which I got from the character map. Like so:
<value column="Back" null="false">H₂</value>
but when I display it on a textview in Android it gives me this 'Hâ,,'
How can I fix this and display it properly in my app?
I found out how
In the XML file the code should be like this :
<value column="Back" null="false">H<sub>2</sub></value>
So that the parced string value is "H<sub>2</sub>"
then in the java code :
TextView textview.setText(Html.fromHtml(YourString);
and for superscript use "sup" instead of "sub"
You can use <small> tag along with <sub> or <sup> tags to decrease the size of the text.
For example:<sup><small>your-string</small></sup>
If you want to still decrease the size of text,you add <small> tag once more like this<sup><small><small>your-string</small></small></sup>
I'm using android studio and it is working perfectly for me !
i found this method useful for me.
strings.xml
<string name="your_string">H<sub>2</sub></string>
You can change it easier than that, just write in #strings or where you want<sub>your-string-here</sub> for subscript or <sup>your-string-here</sup>.
The subscripted letters(of your word) still have the same size as your text. You need to decrease it's size.
For that, use , where number means the size of the text you want.
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
