EditText.setFocusable(false); can't be set to true. :/
Try
etAdd.setFocusableInTouchMode(true);
etAdd.setFocusable(true);
instead of just
etAdd.setFocusable(true);
I use below code focus and click remove and add:
Remove:
secondFirstHalfEditText.setClickable(false);
secondFirstHalfEditText.setFocusable(false);
Add :
editText.setClickable(true);
editText.setFocusableInTouchMode(true);
editText.setFocusable(true);
Must use this For active Edittext >>
editText.setFocusableInTouchMode(true);
Its working for me perfecly
