How to make Enter key the same as the Space Bar key - Android

Question

I have an EditText and when a user uses the enter key it creates a new line. I want the enter key to only make a single space, not a new line. I have no idea to do this. The reason I want to is because when the user clicks Enter it creates a new line and when they submit the message its stored and the database with an empty line and then when its retrieved and displayed on the android phone it displays and empty line.

Answer 1

Try this:

 final EditText edittext = (EditText) findViewById(R.id.edittext);
    edittext.setOnKeyListener(new OnKeyListener() {
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            // If the event is a key-down event on the "enter" button
            if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
                (keyCode == KeyEvent.KEYCODE_ENTER)) {
              // Perform action on key press
              editText.setText(editText.getText() + " ");
              return true;
            }
            return true;
        }
    });

Try this way works perfectly

EditText edit = (EditText) findViewById(R.id.edit);

        InputFilter filter = new InputFilter() {
            public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {

                for (int i = start; i < end; i++) {

                    if (source.charAt(i) == '\n') {
                        return " ";
                    }
                }
                return null;
            }
        };

        edit.setFilters(new InputFilter[] { filter });
