Adding decimal point and Zeros to EditText field, and make it move with input

Question

I need the input to adapt to the final number as they enter the digits, without actually entering the decimal point. The best way to explain this is with an example:

Suppose the user starts off with an EditText field which contains this:

.

The user wants to enter 1234.01 into the field (i.e. the digits 0,1,2,3,4). Then he/she starts by entering 1, and the field should look like this:

0.01

Then:

0.12

Finally:

1234.01

So as you may notice, the decimal places itself accordingly as the numbers are inputted. Is it possible to do this as the numbers are being entered? Thanks.

Can you kindly clarify further what you are looking for, and to post what you have tried to do. — coder, Sep 22 '17 at 06:23

You can achieve this with TextWatcher .

In your xml file, create a EditText like :

<EditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/edt"
    android:inputType="numberDecimal"
    android:textDirection="anyRtl"
    android:gravity="right"/>

Now, In your Java file do something like this with your editText :

final EditText editText = (EditText) findViewById(R.id.edt);
    editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void afterTextChanged(Editable editable) {
            if (editText == null) return;
            String inputString = editable.toString();
            editText.removeTextChangedListener(this);
            String cleanString = inputString.toString().replaceAll("[.]", "");
            BigDecimal bigDecimal = new BigDecimal(cleanString).setScale(2, BigDecimal.ROUND_FLOOR).divide(new BigDecimal(100), BigDecimal.ROUND_FLOOR);
            String  converted = NumberFormat.getNumberInstance().format(bigDecimal).replaceAll("[,]","");
            editText.setText(converted);
            editText.setSelection(converted.length());
            editText.addTextChangedListener(this);
        }
    });
