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
