How to remove hyphen from TextUtils.split(line, "-")?

I found a dictionary sample in GitHub that I am currently experimenting with. The sample database used hyphen between the searched word and the word's meaning. So something like this.
abbey - n. a monastery ruled by an abbot
I looked into the dictionary database java file and found the following code:
String[] strings = TextUtils.split(line, "-");
I have my own database that translates Korean words to English. However I didn't use hyphen while creating it. So is there a way to not use hyphen or any other symbols but simply spaces? Also this is part of an android app.
Edit- An example of my own dictionary would be something like
abbey a monastery ruled by an abbot
Edit-
The problem here is that the old code only differentiates and recognizes the words and the meaning only if they are separated by hyphen. How do I make this so it works with spaces alone.

To remove a character in a String use String.replace
String newString = line.replace("-","");
To replace with a space simply use
String newString = line.replace("-"," ");

String mystring = mystring 1.replace("_"," "); if you want space give space.

As I understand it, you want to split your String to get the output like
abbey - n. a monastery ruled by an abbot
[abbey][n. a monastery ruled by an abbot]
You can use String.split(String, int) to force the number of split.
The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n - 1 times
Let's use it like :
String[] array = s.split(" ", 2);
This will split your String on the regex " " but will limit the size of the output to 2 cells. So it will only split once, put the left part on the first cell and the right part on the second cell.
Without this limit argument, the method would keep split the right part again using a bigger array.
Note: this will be a problem if your word is a sentence in the left part.

Converting a text file into String array with regular expression

I have a .txt file which contains above 1000 words
sample city names below
Razvilka
Moscow
Firozpur Jhirka
Kathmandu
Kiev
Pokhara
Merida
Delhi
Reshetnikovo
Ciudad Bolivar
Marfino
Zhukovskiy
Reutov
Kurovskoye
etc
I would like to have these words in this format below
"Razvilka","Moscow","etc","etc"
enclosed with double quotation and with a comma in the end.I am using Notepad++.Could you mention how to do it and which software should I use it?

If you're using Notepad++, make a Search and Replace replacing
\b(\w+)\b
with
"$1",
It'll find all words and replace with them self, surrounded by quotes. You'll have to manually remove the last , if that's unwanted.

I wonder if this question is about programming, but You tagged android, regex and android studio, so I guess it is. If yes, You can simply split a string in that way:
String[] splitted = yourString.split("\\s+");
In that case, You are splitting the strings by whitespaces (this regex is also for more than one whitespace), like Your string seems to be. If You have more than one delimiter, You can do it by using the OR operator |
String[]splitted = yourString.split("-|\\.");
In that example, You are splitting the String by - and . (minus and point). The delimiter is the sign where the String is splitted by.

Android Regular Expression - Replace all spaces '(' ')' '-'

I newt o regular expressions and been using tutorials, but the regular express I have works sometimes, but doesn't all the time. I am getting my numbers out of the contact list from my android phone. I am trying to get rid of all spaces, '(', ')', and '-'
For example:
1. (555) 867-5309 -> 5558675309
2. 1555-555-5555 -> 15555555555
3. 555-555-5555 -> 5555555555
This is the line I am using
String formatphone = contactPhone.replaceAll("\\s()-","");
For some numbers it only returns number and sometimes it doesn't change the format.
Is it correct? Do i need to format something because I am taking it out of the phone's contact list?

Put the desired characters in a character class:
String formatphone = contactPhone.replaceAll("[ ()-]","");
Ensure that you put the hyphen - at either end.

Try using this:
String formatphone = contactPhone.replaceAll("^.*[\\s\\(\\)-].*", "");
As a regular expression you're defining a set using []. In that set you include any character you want to be replaced. As ( and ) are special meaning characters, you have to escape them. As the - is a special character used to design ranges, it has to be the last character of your set, so if nothing is behind it, it's not a range, but just that character (you could escape it too, though).

Android: converting between Strings, SpannedStrings and Spannablestrings

I have a string resource called "foo". It may be a simple string... or it may contain HTML. This may change over time: I should be able to box it up as at least a SpannableString immediately upon reading whether it's HTML or not (but how??)
I want to get that raw CharSequence and first be able to display it as-is (the exact characters, not Android's "interpretation" of it). Right now I can't do that... toString() decides to rip out the parts it doesn't think I want to see.
I'd then like to be able to create a SpannableString from this and other Strings or SpannableStrings via concatenation using some method (none of the normal ones work). I'd like to then use that SpannableString to display the HTML-formatted text in a TextView.
This shouldn't be difficult, but clearly I'm not doing it right (there's very little info out there about this that I've found so far). Surely there is a way to accurately interconvert between between Strings, SpannedStrings and even Spannablestrings, without losing the markups along the way?
Note that I've already played with the somewhat broken Linkify, but I want better control over the process (no dangling unformatted "/"s, proper hrefs, etc.) I can get this all to work IF I stay in HTML at all steps, though I can't concatenate anything.
Edit 1: I've learned I can use the following to always ensure I get my raw string (instead of whatever Android decides it thinks the CharSequence really is). Nice... now, how to coax this into a SpannableString?
<string name="foo"><![CDATA[
<b>Some bold</b>
]]>
</string>
Edit 2: Not sure why this didn't work earlier, but... if foo1 and foo2 are strings marked up as above (as CDATA), then one can apparently do this:
String foo1 = (String)getResources().getText(R.string.foo1);
String foo2 = (String)getResources().getText(R.string.foo2);
SpannedString bar = new SpannedString(Html.fromHtml(foo1+foo2));
Curious: is there a more straightforward solution than this? Is this CDATA business actually necessary? It seems convoluted (but not as convoluted as never quite knowing what the resource type will be... String, Spannable, etc.)

I had the same problem. There are two solutions according to Google API Guides.
First is to escape < mark with < in the string resource. Unfortunately, String conversion removes the tag in the background.
Second is to use Format Strings instead of XML/HTML tags. It seems simpler, faster, and evades hidden conversion problems. getString(resource, ...) works like a printf(string, ...) here.
Both work and require some code to replace given part of the string anyway (handle tags or format strings). Enjoy! =)

It appears there isn't a more straightforward way to accomplish this.

New Line character \n not displaying properly in textView Android

I know that if you do something like
myTextView.setText("This is on first line \n This is on second line");
Then it will display properly like this:
This is on first line
This is on second line
When I store that string in a database and then set it to the view it displays as such:
This is on first line \n This is on second line
Here is the line of code I use to extract the string from the database:
factView.setText(factsCursor.getString(MyDBAdapter.FACT_COLUMN));
I simply populate the database from a text file where each line is a new entry into the table so a line would look like this "This is on first line \n This is on second line" and it is stored as text.
Is there a reason that it isn't displaying the \n characters properly? It must be something to do with the string being in the database. Any suggestions?

I found this question Austyn Mahoney's answer is correct but here's a little help:
private String unescape(String description) {
return description.replaceAll("\\\\n", "\\\n");
}
description being the string coming out of your SQLite DB

As Falmarri said in his comment, your string is being escaped when it is put into the database. You could try and unescape the string by calling String s = unescape(stringFromDatabase) before you place it in your TextView.
As a side note, make sure you are using DatabaseUtils.sqlEscapeString() on any kind of data that is from the user or an unknown changeable source when inserting data into the database. This will protect you from errors and SQL Injection.

Try \\n instead of \n. If it throws an exception than use newline keyword in place of \n....newline is one character, ascii 10; it's often entered in a string literal...and will serve your purpose....:)

"This is on first line"||x'0A'||"This is on second line"
The || concatenates strings and the x'0A' is an unescaped newline.
If you're inserting records you'll have to replace every newline with "||x'0A'||" (If your string is double quoted). This may seem clumsy compared to the other asnswers. However if your lines are in separate columns this also works in a select:
SELECT firstline||x'0A'||secondline FROM wherever;
I found this while having the same problem you are: http://www.mail-archive.com/sqlite-users#sqlite.org/msg43557.html

A text area can be in multi line or single line mode. When it is in single line mode newline characters '\n' will be treated as spaces. When in doubt, to switch multi line mode on you can use the following code:
setInputType(getInputType() | InputType.TYPE_TEXT_FLAG_MULTI_LINE);
I had the problem that the same code did not work on honeycomb and on froyo, which seem to have different defaults. I am now also excluding the flag when I want to force a field to be single lined.
From the Android doc:
public static final int TYPE_TEXT_FLAG_MULTI_LINE Added in API level 3
Flag for TYPE_CLASS_TEXT: multiple lines of text can be entered into
the field. If this flag is not set, the text field will be
constrained to a single line. Constant Value: 131072 (0x00020000)
http://developer.android.com/reference/android/text/InputType.html#TYPE_TEXT_FLAG_MULTI_LINE
You have to set the flag before you populate the field.
