Get only number not comma in edittext on process

Question

I have this code to detect number format from my EditText input.

public class NumberTextWatcher implements TextWatcher {

    private DecimalFormat df;
    private DecimalFormat dfnd;
    private boolean hasFractionalPart;

    private EditText et;

    public NumberTextWatcher(EditText et)
    {
        df = new DecimalFormat("#,###.##");
        df.setDecimalSeparatorAlwaysShown(true);
        dfnd = new DecimalFormat("#,###");
        this.et = et;
        hasFractionalPart = false;
    }

    @SuppressWarnings("unused")
    private static final String TAG = "NumberTextWatcher";

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

        try {
            int inilen, endlen;
            inilen = et.getText().length();

            String v = s.toString().replace(String.valueOf(df.getDecimalFormatSymbols().getGroupingSeparator()), "");
            Number n = df.parse(v);
            int cp = et.getSelectionStart();
            if (hasFractionalPart) {
                et.setText(df.format(n));
            } else {
                et.setText(dfnd.format(n));
            }
            endlen = et.getText().length();
            int sel = (cp + (endlen - inilen));
            if (sel > 0 && sel <= et.getText().length()) {
                et.setSelection(sel);
            } else {
                // place cursor at the end?
                et.setSelection(et.getText().length() - 1);
            }
        } catch (NumberFormatException nfe) {
            // do nothing?
        } catch (ParseException e) {
            // do nothing?
        }

        et.addTextChangedListener(this);
    }

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

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count)
    {
        if (s.toString().contains(String.valueOf(df.getDecimalFormatSymbols().getDecimalSeparator())))
        {
            hasFractionalPart = true;
        } else {
            hasFractionalPart = false;
        }
    }

}

And then call it in activity.

JumlahTrx = (EditText)findViewById(R.id.editJumlah);
JumlahTrx.addTextChangedListener(new NumberTextWatcher(JumlahTrx));

And it will produce 5,000 if I input the field. What I want is when I click on button the value 5,000 become 5000 and then insert to my database. Because I set on INT in my database.

Any help will be nice. Thanks

====================== UPDATE

add this code

String data = JumlahTrx.getText().toString();
data=data.replaceAll(",","");
int value=Integer.parseInt(data);
JumlahTrx.setText(value);

and got this error when on button click to save it in database

Error you're getting is entirely justified. It's invalid to call TextView::setText with arbitrary integer values. Please read what that method actually does and expects. — M. Prokhorov

You may use replace or replaceAll function before saving data to database For Example

String data = "5,000";
data= data.replaceAll(",","");

Int value = Integer.parseInt(data);

Store that value to your data base

Updated

in your doInBackGround

Change

hashMap.put("JumlahTrx",params[2]);

To

 String a = params[2];
 a=a.replaceAll(",","");
 hashMap.put("JumlahTrx",a);
