I think you might be looking for a TextWatcher. You can assign it to an EditText:

inputTitle.addTextChangedListener(new TextWatcher() {

        @Override

        public void beforeTextChanged(CharSequence s, int start, int count, int after) {



        }



        @Override

        public void onTextChanged(CharSequence s, int start, int before, int count) {



            String str = s.toString();



            if(str.length() > 0 && str.charAt(str.length() - 1) == 'n') {

                //Run the onClick code here

            }





        }



        @Override

        public void afterTextChanged(Editable s) {



        }

    });

Actually an empty TextBox is empty when there is no text, that's correct.

But what if you try using the string method contains('n); after getText()?

    public void onClickDone(View view) {

         String myInputTitle = inputTitle.getText().toString();

         String myInputDesc = inputDesc.getText().toString();

         if (myInputTitle.isEmpty() || myInputDesc.isEmpty() || !myInputTitle.getText().toString().contains('n')) {

         Snackbar.make(view, "Please fill in both form!", 

         Snackbar.LENGTH_SHORT).show();

     } else {

         dbManager.insert(myInputTitle, myInputDesc);

         Intent intent = new Intent(AddItem.this, 

         MainActivity.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

         startActivity(intent);

     }

}
