Any of those help I want to put specific format while entering value in my edittext. , Use a textwatcher as follows:
code :
private class GenericTextWatcher implements TextWatcher{

        private View view;
        private GenericTextWatcher(View view) {
            this.view = view;
        }

        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {}
        public void onTextChanged(CharSequence s, int i, int i1, int i2) {

            switch(view.getId()){
            case R.id.ed_youredittextid://this is your xml id
                 insertCommaIntoNumber(ed_youredittextid,s);
                break;
         }
        }

        public void afterTextChanged(Editable editable) {

        }
    }

        private void insertCommaIntoNumber(EditText etText,CharSequence s)
        {
            try {
                if (s.toString().length() > 0) 
                {
                    String convertedStr = s.toString();
                    if (s.toString().contains(".")) 
                    {
                        if(chkConvert(s.toString()))
                            convertedStr = customFormat("###,###.##",Double.parseDouble(s.toString().replace(",","")));
                    } 
                    else
                    {
                        convertedStr = customFormat("###,###.##", Double.parseDouble(s.toString().replace(",","")));
                    }

                    if (!etText.getText().toString().equals(convertedStr) && convertedStr.length() > 0) {
                        etText.setText(convertedStr);
                        etText.setSelection(etText.getText().length());
                    }
                }

            } catch (NullPointerException e) {
                e.printStackTrace();
            }
        }


 public String customFormat(String pattern, double value) {
        DecimalFormat myFormatter = new DecimalFormat(pattern);
        String output = myFormatter.format(value);
        return output;
    }

    public boolean chkConvert(String s)
    {
        String tempArray[] = s.toString().split("\\.");
        if (tempArray.length > 1) 
        {
            if (Integer.parseInt(tempArray[1]) > 0) {
                return true;
            }
            else 
                return false;
        }
        else
            return false;
    } 
edyourdittext.addTextChangedListener(new GenericTextWatcher(edyouredittext));
//this is the edittext with which you want to bind the textwatcher

will help you Please check the image below for reference. When I copy any text from webpage and paste it in Edittext in my app, Pasted text sometimes is already formatted and is different than default text. How can I keep pasted text to have default text style same as of Edittext. , Try removing spans in afterTextChanged()
code :
public void afterTextChanged(Editable s)
{
    CharacterStyle[] toBeRemovedSpans = s.getSpans(0, s.length(),
                                                MetricAffectingSpan.class);
    for (int index = 0; index < toBeRemovedSpans.length; index++)
        s.removeSpan(toBeRemovedSpans[index]);
    }
}

this will help After exploring more on this issue, I have found the solution. Where I am calculating the cursor position. I have removed onSelectionChanged(...) method from my code and I am handling selection inafterTextChanged(...) method. In the following code I have made changes in afterTextChanged(...) :
code :
@Override
    public void afterTextChanged(Editable editable) {

        String str = editable.toString();
        String number = str.replaceAll("[,]", "");
        if (number.equals(previousNumber) || number.isEmpty()) {
            return;
        }
        previousNumber = number;

        int startText, endText;
        startText = editText.getText().length();

        int selectionStart = editText.getSelectionStart();

        String formattedString = prefix + formatNumber(number);
        editText.removeTextChangedListener(this);
        editText.setText(formattedString);
        endText = editText.getText().length();

        int selection = (selectionStart + (endText - startText));
        editText.setSelection(selection);

        editText.addTextChangedListener(this);
    }
