I am currently trying to fix my problem with string length at buttons, in android application. So i parse string and then set it as button text. But if one text is bigger then 9 characters or 10 it gets displayed out of the button overlay. I know i could make text smaller but this is not good solution because i already have small text.
So what you guys recommend for example if i have:
String text = "ThisIsSomeRealyLongText";
How can i split this string in 2 lines or when i reach character number 9 just use /n (to break text)?
Using too much text on a button is never a good idea. You should think about using an icon, or shorter text with (if needed) more explanation text somewhere else. Remember,the best UX will be the one with the least amount of reading involved.
Using regex you can do this. It will break the string into 9 characters per line.
text = text.replaceAll("(.{9})", "$1\n");
Use
(new line):
android:text = "ThisIsSome
RealyLongText"
But in code, you can just use \n. You can define in ../res/values/strings.xml:
<string name="longname">ThisIsSome\nRealyLongText</string>
then set the text for you button
android:text="#string/longname"

Is there any way to make a some text appear as a paragraph, since at the moment i use,
private String howtoplay = "[Insert How To Play THe Game Instructions Here]";
When i use strings the text just goes off my game screen which is 800 pixels by 600 pixels.
How do i make it so it doesn't go out of the screen and just either just a block of text, or that when the word reaches the end of the game screen, it will start on a new line.
I have only used strings and so i have been used t using them to create small amounts of text like the title and small commands instructing what button to click.
So in short, is there any way to create a block of text without creating like another class, or just creating a bunch of strings?
EDIT:
So it turns out that i cannot create a new line break, due to the fact i have a drawString
g.drawString(title, ((Sea_InvadersDisplay.WIDTH/2)-(titleWidth/2))-2, (Sea_InvadersDisplay.HEIGHT/2)-123);
and i have found the solution here:
Problems with newline in Graphics2D.drawString
So in other words i have found the solution to my problem.
use can \n to break to the next line and you can use.
everytime you need to move to a new line or new row u just pass \n into your string
Try to use html code.... new line in html code is represented by <br/> tag... so you will have something like this:

I have a search function that scrolls through a String and finds specific instances of a substring and then notes the index for the location of the substring.
For example, if I'm trying to find the String
"AATACG"
in the string
"TACGATCAATACGACGATCAGT",
it will return 7 as the index of the substring. What I need is a way to color the substring. So, the return text will be
"TACGATCAATACGACGATCAGT",
but with the substring colored. The text is outputted to a JavaFX TextArea.
I've tried using ANSI codes (which didn't work); I've also tried changing the string into a Text object and setting the fill color/applying a CSS id, but I can't find a way to change the Text back into a String with the color change remaining.
Is there a way to do this? Any help is much appreciated.
How about using javafx.scene.text.TextFlow? Seems like you want to highlight text without editing it. In this case TextFlow is appropriate component.
I have textview with droid sans mono font. Max line lenght is 10 characters. gettin it by this function.
this.getPaint().breakText(FULLTEXT, 0, 100, true, this.getWidth(), null);
I want lines always full if there is text and not the break halfway or something similar.
If I am using only normal characters like numbers and letters its working but for characters like "." or "," in certain situations the line break.
For example: if i have line:
"0123456789" or ".012345678"
tv is working as i want.. line is full..but with input:
"Y.012345678"
the line break this way:
".xxxxxxxxx"
"012345678Y"
where x are empty spaces.
i want to have multiline, i just dont want empty spaces (just in last line)
If i insert two special character like:
"01234\\.789"
its start breaking halfway if line is full. how i understand it, textview is breaking sentences which are too long for line.
Curently i am inputing different chareacter without this behaviour, but i would be happy if i didn't need too do this. (too much corections need too be done and its messy)
I noticed that descripted behaviour is not on every android version. I have devices with android 2.3.6, 4.0.4 and kindle fire version. I don't have problem on 2.3.6.
Is there a way how to disable this textview behaviour? thanks.
android:singleLine="true"
is the property of textview and edittext which will keep the text on single line. if length of string is too big then text will be truncated but will never go on next line.
I am trying to write Persian text to a .txt file in Java. Because Persian (Farsi) is read from right to left, how can I write each line such that it is right aligned?
I am currently using Apache's FileUtils.writeLines(), but I am open to other alternatives in order to achieve the problem.
Thanks!
Text alignment is determined by UI that would show your text file. If you are using a plain text file, so it does not have facilities to tell it its text alignment.
If you insist on it, there are special Unicode characters that can tell UI it must be interpreted as right-to-left text. Please see here.
You can wrap each line into a String.format
String.format("%s", formatter.format(i))
or
Apache StringUtils has several methods: leftPad, rightPad, center and repeat.

How can I pad a String in Java?
You just add spaces if you want to have lines with specific size, otherwise it depends on the tool you use for reading it.
In my application, Im having a Textview containing text in this style:
"123131 (Ø 374)"
On small devices, the text reaches the viewborder causing a new line at one of these spaces. In some cases, this makes the text look like this:
"123131 (Ø
374)"
Is there a way to force the new line to the first whitespace without using 2 TextViews? Isnt there some kind of "protected white space" or something like this?
"123131
(Ø 374)"
regards
danijoo
I solved it by recplacing all whitespaces but one with the unicode code for a nonbreaking whitespace:
"123131 (Ø\u00a0374)"
What I'd do is:
Implement a custom TextView with a listener when Ellipsis is triggered:
http://thanksmister.com/2012/10/16/android-textview-with-ellipsis-listener/
Then, when receiveing the listener, programmatically adding a '\n' character right before the '(' character.
Remember to set that TextView to be multi line.
