Cursor Focus EditText Detection (CFED)

Hello geas, on this occasion I want to try to share a unique experience when completing a special client project. At that time I was making a validation form where there was one field whose input had to be the nominal value of Indonesian money, where there had to be a dot separator in every thousand. Therefore I need to listen to where the cursor is focused, to be able to activate or disable certain components while formatting the nominal value of money.

Solution

It turns out I need to use the interface  OnFocusChangeListener() and then TODO SOMETHING or do something in its override like  onFocusChange, like the example below.

for (EditText view : editList){
   view.setOnFocusChangeListener(focusListener);
}
....
private OnFocusChangeListener focusListener = new OnFocusChangeListener() {
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus){
             focusedView = v;
        } else {
             focusedView  = null;
        }
    }
}
