android – How to Automatically add thousand separators as number is input in EditText-ThrowExceptions

Exception or error:

Im creating a convertor application, I want to set the EditText so that when the user is inputting the number to be converted, a thousand separator (,) should be added automaticaaly in realtime to the number once it increaments by 3 figures…..thousand, million, billion etc
and when erased to below 4 figures the number goes back to normal.
Any help?
Thank You.

How to solve:

You can use String.format() in a TextWatcher. The comma in the format specifier does the trick.

This does not work for floating point input. And be careful not to set an infinite loop with the TextWatcher.

public void afterTextChanged(Editable view) {
    String s = null;
    try {
        // The comma in the format specifier does the trick
        s = String.format("%,d", Long.parseLong(view.toString()));
    } catch (NumberFormatException e) {
    }
    // Set s back to the view after temporarily removing the text change listener
}

Solved The Issue Finally

Even-though It is too late answer. I’ve researched much to accomplish the task To get the proper result but could not. So I finally solved the issue we were searching and provided this answer to the google searchers for saving their times on searching.

Fetures of the following codes

  1. Puts thousand separator in EditText as it’s text changes.

  2. adds 0. Automatically when pressed period (.) At First.

  3. Ignores 0 input at Beginning.

Just copy the following
Class named

NumberTextWatcherForThousand which implements TextWatcher

import android.text.Editable;
import android.text.TextWatcher;
import android.widget.EditText;
import java.util.StringTokenizer;

/**

public class NumberTextWatcherForThousand implements TextWatcher {

    EditText editText;


    public NumberTextWatcherForThousand(EditText editText) {
        this.editText = editText;


    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void afterTextChanged(Editable s) {
        try
        {
            editText.removeTextChangedListener(this);
            String value = editText.getText().toString();


            if (value != null && !value.equals(""))
            {

                if(value.startsWith(".")){
                    editText.setText("0.");
                }
                if(value.startsWith("0") && !value.startsWith("0.")){
                    editText.setText("");

                }


                String str = editText.getText().toString().replaceAll(",", "");
                if (!value.equals(""))
                editText.setText(getDecimalFormattedString(str));
                editText.setSelection(editText.getText().toString().length());
            }
            editText.addTextChangedListener(this);
            return;
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
            editText.addTextChangedListener(this);
        }

    }

    public static String getDecimalFormattedString(String value)
    {
        StringTokenizer lst = new StringTokenizer(value, ".");
        String str1 = value;
        String str2 = "";
        if (lst.countTokens() > 1)
        {
            str1 = lst.nextToken();
            str2 = lst.nextToken();
        }
        String str3 = "";
        int i = 0;
        int j = -1 + str1.length();
        if (str1.charAt( -1 + str1.length()) == '.')
        {
            j--;
            str3 = ".";
        }
        for (int k = j;; k--)
        {
            if (k < 0)
            {
                if (str2.length() > 0)
                    str3 = str3 + "." + str2;
                return str3;
            }
            if (i == 3)
            {
                str3 = "," + str3;
                i = 0;
            }
            str3 = str1.charAt(k) + str3;
            i++;
        }

    }

    public static String trimCommaOfString(String string) {
//        String returnString;
        if(string.contains(",")){
            return string.replace(",","");}
        else {
            return string;
        }

    }
}

Use This Class on your EditText as follows

editText.addTextChangedListener(new NumberTextWatcherForThousand(editText));

To get the input as plain Double Text

Use the trimCommaOfString method of the same class like this

NumberTextWatcherForThousand.trimCommaOfString(editText.getText().toString())

  public static String doubleToStringNoDecimal(double d) {
        DecimalFormat formatter = (DecimalFormat) NumberFormat.getInstance(Locale.US);;
        formatter .applyPattern("#,###");
        return formatter.format(d);
    }

###

This sample app deconstructs formatting numbers clearly.

To summarize the link above, use a TextWatcher and in the afterTextChanged() method format the EditText view with the following logic:

@Override
public void afterTextChanged(Editable s) {
    editText.removeTextChangedListener(this);

    try {
        String originalString = s.toString();

        Long longval;
        if (originalString.contains(",")) {
            originalString = originalString.replaceAll(",", "");
        }
        longval = Long.parseLong(originalString);

        DecimalFormat formatter = (DecimalFormat) NumberFormat.getInstance(Locale.US);
        formatter.applyPattern("#,###,###,###");
        String formattedString = formatter.format(longval);

        //setting text after format to EditText
        editText.setText(formattedString);
        editText.setSelection(editText.getText().length());
    } catch (NumberFormatException nfe) {
        nfe.printStackTrace();
    }

    editText.addTextChangedListener(this);
}

I know i am very late to the party but it may be very useful for future users. My answer is an extension of Shree Krishna‘s answer.

Improvements:

  1. Thousands separators and Decimal markers are locale aware i.e. they are used accordingly to the Locale of the device.
  2. The cursor position doesn’t change after deleting or adding elements in the middle also (In his answer cursor was reset to the end).
  3. The overall quality of the code has been improved specially the getDecimalFormattedString method.

Code:

    import android.text.Editable;
    import android.text.TextWatcher;
    import android.widget.EditText;

    import java.text.DecimalFormat;

Using

<.ThousandNumberEditText

You can use this method:

myEditText.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                }

                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {

                    String input = s.toString();

                    if (!input.isEmpty()) {

                        input = input.replace(",", "");

                        DecimalFormat format = new DecimalFormat("#,###,###");
                        String newPrice = format.format(Double.parseDouble(input));


                        myEditText.removeTextChangedListener(this); //To Prevent from Infinite Loop

                        myEditText.setText(newPrice);
                        myEditText.setSelection(newPrice.length()); //Move Cursor to end of String

                        myEditText.addTextChangedListener(this);
                    }

                }

                @Override
                public void afterTextChanged(final Editable s) {
                }
            });

And to get original text use this:

String input = myEditText.getText().toString();
input = input.replace(",", "");

###

This solution has some advantage over other answers. For example, it keeps the user’s cursor position even if they edit the beginning or middle of the number. Other solutions always jump the cursor to the end of the number. It handles decimals and whole numbers, as well as locales that use characters other than . for the decimal separator and , for the thousands grouping separator.

class SeparateThousands(val groupingSeparator: String, val decimalSeparator: String) : TextWatcher {

    private var busy = false

    override fun afterTextChanged(s: Editable?) {
        if (s != null && !busy) {
            busy = true

            var place = 0

            val decimalPointIndex = s.indexOf(decimalSeparator)
            var i = if (decimalPointIndex == -1) {
                s.length - 1
            } else {
                decimalPointIndex - 1
            }
            while (i >= 0) {
                val c = s[i]
                if (c == groupingSeparator[0] ) {
                    s.delete(i, i + 1)
                } else {
                    if (place % 3 == 0 && place != 0) {
                        // insert a comma to the left of every 3rd digit (counting from right to
                        // left) unless it's the leftmost digit
                        s.insert(i + 1, groupingSeparator)
                    }
                    place++
                }
                i--
            }

            busy = false
        }
    }

    override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
    }

    override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
    }
}

Then in xml:

  <EditText
    android:id="@+id/myNumberField"
    android:digits=",.0123456789"
    android:inputType="numberDecimal"
    .../>

And finally register the watcher:

findViewById(R.id.myNumberField).addTextChangedListener(
    SeparateThousands(groupingSeparator, decimalSeparator))

To handle . vs , in different locales use groupingSeparator and decimalSeparator, which can come from DecimalFormatSymbols or localized strings.

###

you can use this code in many ways in your program, you give it a string and it separate each three from right and place space there.

private String Spacer(String number){
    StringBuilder strB = new StringBuilder();
    strB.append(number);
    int Three = 0;

    for(int i=number.length();i>0;i--){
        Three++;
        if(Three == 3){
            strB.insert(i-1, " ");
            Three = 0;
        }
    }
    return strB.toString();
}// end Spacer()

u can change it a bit and use it ontextchangelistener.
good luck

Since i had the same problem i decided to find a solution to it

Find my function below i hope it helps people finding solution

securityDeposit.addTextChangedListener(new TextWatcher() {

I just wanted comma to be placed and this is working for me:

String.format("%,.2f", myValue);

The answers here lack a method to handle actual user input, such as deleting characters or copying and pasting. This is an EditText field. If you want to add formatting in, you need to support editing that formatted value.

This implementation still has a deficiency depending on your use case. I didn’t care about decimal values and assumed I would only be handling whole numbers. There’s enough of how to handle that on this page and how to handle actual internationalization that I’ll leave that as an exercise to the reader. If you need to do that, it shouldn’t be too difficult to add “.” to the regular expression to keep the decimal; you’ll just have to be careful to acknowledge the numeral string still has a non numerical character.

This is designed to be used throughout multiple activities. New it once, give it your edit text and your data model and ignore it. The model binding can be removed if you don’t need it.

}

At a highlevel, what that does is:

  • Determine which numbers were actually in the string after it was edited
  • Process the edit to the numeral version of the string if the numbers weren’t edited
  • Convert the numeral back to a formatted string
  • Determine, where the cursor should be based on where editing began and how much text was added

It also nicely handles edge cases like completely deleted input, integer overflow and erroneous input.
