Answer 4

As you are doing formatting in TextWatcher (##,####....) ie you are adding "," in EditText and you have made the EditText as numeric. If its numeric then "," char is invalid. Thus its not allowing TextWatcher to update the formatted text that contains ',".

You have 3 options to deal with this problem :

1. Make the EditText as normal instead of numeric. In TextWatcher look out for any other invalid chars other than 0-9. You can show IME for Mumber keypad when the focus is on the EditText.
2. Use Mask for EditText.
3. Let it be numeric. Trap FocusGain & FocusLost for the EditText. In focusGain, remove the formatting & set the inputType to Numeric. & In focusLost, first make the input type to Normal and then update the entered value to formmated value. You can set the input type to normal at runtime using setInputType(InputType.TYPE_TEXT_VARIATION_NORMAL); & for numeric use : setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);

I believe 1st option will be best to handle and manage out.
