Android - Decimal Formatter

I've try this in my device and work fine. But, in some Android device, the symbol is in wrong place. This is my code :
public static String convertToRupiah(String priceBeforeConverted){
//manual setting separator, because currently RUPIAH is NOT supported
DecimalFormat formatter = (DecimalFormat) DecimalFormat.getCurrencyInstance();
DecimalFormatSymbols formatRupiah = new DecimalFormatSymbols();
formatRupiah.setCurrencySymbol("Rp ");
formatRupiah.setMonetaryDecimalSeparator(',');
formatRupiah.setGroupingSeparator('.');
formatter.setDecimalFormatSymbols(formatRupiah);
Double price = StringFormatter.isNullOrEmpty(priceBeforeConverted) ? 0.00 : Double.valueOf(priceBeforeConverted) ;
String conversionResult = formatter.format(price);
if(conversionResult.endsWith(",00"))
conversionResult = conversionResult.substring(0, conversionResult.length()-3);
return conversionResult;
}
expected result is : Rp 25.000,00

String pattern = "Rp ###,###.000 ";
DecimalFormat decimalFormat = new DecimalFormat(pattern);
String format = decimalFormat.format(25.000);
System.out.println(format);
--Try this, your zeros after decimal place will not miss. Output of this code is.
Rp 25.000
Let me know if anything is not clear.

Split datetime from string android

I have String s = http://kqxs.net.vn/xo-so-ngay/an-giang-xsag-23-4-2015/
(Using Java android)how to split date string 23-4-2015 from it become two substring:
http://kqxs.net.vn/xo-so-ngay/an-giang-xsag
23-4-2015

Use the substring method
String str = "http://kqxs.net.vn/xo-so-ngay/an-giang-xsag-23-4-2015/";
url = str.substring(0, 43);
date = str.substring(44, 53);

I hope the date will always be on the last. So you can actualy do Java substring take the last 11 char from the end. Because there is "/".
Hard way you can actually do a RegEx to get only a number. But it is not possible if in the URL there is a numerical too.

Try this using regular expressions,
String str = "http://kqxs.net.vn/xo-so-ngay/an-giang-xsag-23-4-2015/";
String regexStr = "\\d{2}-\\d{1,2}-\\d{4}";
Pattern pattern = Pattern.compile(regexStr);
Matcher matcher = pattern.matcher(str);
int startIndex=-1;
// Check all occurrences
while (matcher.find()) {
startIndex = matcher.start();
}
if(startIndex>0){
String firstPart = str.substring(0,startIndex-1);
String secondPart = str.substring(startIndex);
System.out.println("First Part "+firstPart);
System.out.println("Second Part "+secondPart);
}else{
System.out.println("Match Not Found!");
}
Output:-
First Part http://kqxs.net.vn/xo-so-ngay/an-giang-xsag
Second Part 23-4-2015/

Try This code for The Get the date from the String.
String str="fgdfg12°59'50\" Nfr | gdfg: 80°15'25\" Efgd";
String[] spitStr= str.split("\\|");
String numberOne= spitStr[0].replaceAll("[^0-9]", "");
String numberSecond= spitStr[1].replaceAll("[^0-9]", "");
Try this another code
String str=" abc d 1234567890pqr 54897";
Pattern pattern = Pattern.compile("\\w+([0-9]+)\\w+([0-9]+)");
Matcher matcher = pattern.matcher(str);
for(int i = 0 ; i < matcher.groupCount(); i++) {
matcher.find();
System.out.println(matcher.group());
}

DecimalFormat using Turkish Format

My format is
DecimalFormat decimalformat = new DecimalFormat("0.00##");
But my user is Turkish,Russian etc. They different local. They using my app . Give error look like this
For Turkish ,"10,00"
My Error;
java.lang.NumberFormatException:Invalid Double:"10,00"

Have not enough information how do you parse the input, but i suggest you to do it this way:
static String parseInput(String input) throws ParseException {
DecimalFormat dFormat = new DecimalFormat("0.00##");
Number number = dFormat.parse(input);
// double numAsDouble = number.doubleValue();
return number.toString();
}
Not really nice, but you could also try to parse the input by replacing ',':
static String parseInputByReplace(String input) throws ParseException {
DecimalFormat dFormat = new DecimalFormat("0.00##");
double number = Double.parseDouble(input.replace(',', '.'));
return dFormat.format(number);
}

You should parse using the culture of the user. decimal.Parse will do that. If you use a culture of your own it means you are explicitly "telling" the parser to only use that format.

How to show it point after two digit in java?

I am Android developer.I get from web service result 45.0000.i am stored ArrayList.But i want show it point after two digit only.
Example output 45.00 only .Please give me solution.

Use DecimalFormat class to achieve this.
DecimalFormat df=new DecimalFormat("##.##");
String formate = df.format(value);
double finalValue = (Double)df.parse(formate) ;

you can use String.format, it returns a formatted string using the specified format string and arguments
String.format("$%.2f", value);
also String.format uses your Locale
int index = 0;
for (; index < yourList.size (); index++) {
String tmpvalue = yourList.get(index);
String conValue = String.format("$%.2f", Float.parse(tmpvalue));
yourList.set(index, conValue);
index++;
}

Android String format - price

Is there an easy formatter to format my String as a price?
So my string is: 300000 i'd like to "300 000" with space
or 1000000 "1 000 000"
Leslie

This does it:
String s = (String.format("%,d", 1000000)).replace(',', ' ');

Use Formatter class to format string
format("%,d", 1024);
After that replace , with space.
http://developer.android.com/reference/java/util/Formatter.html

You cannot do this with a simple format string but with the DecimalFormat and DecimalFormatSymbols class.
int value = 123456789;
DecimalFormat fmt = new DecimalFormat();
DecimalFormatSymbols fmts = new DecimalFormatSymbols();
fmts.setGroupingSeparator(' ');
fmt.setGroupingSize(3);
fmt.setGroupingUsed(true);
fmt.setDecimalFormatSymbols(fmts);
TextView txt = (TextView) findViewById(R.id.txt);
txt.setText(fmt.format(value));
There are lots and lots of other options in these classes. For example you could seperate the numbers with dots or commas or use a locale specific setting.
For example you can use the fmt.setCurrency method:
fmt.setCurrency(Currency.getInstance(Locale.GERMANY));

double yourPrice = 1999999.99;
String formattedPrice = new DecimalFormat("##,##0.00€").format(yourPrice);
output :
formattedPrice = 1.999.99,99€

if you have integer value, most elegant in my opinion
public static String formatNumberWithSpaces(long number) {
DecimalFormat formatter = (DecimalFormat) NumberFormat.getInstance();
DecimalFormatSymbols symbols = formatter.getDecimalFormatSymbols();
symbols.setGroupingSeparator(' ');
return formatter.format(number);
}
