  • It's Simple... Just listen for `keyup` event on Activity/Fragment or the `EditText` where you want the text to appear.. For more Info you should see: [This Question](https://stackoverflow.com/questions/7305972/edittext-onkeydown) – Syed Ali Naqi Jul 09 '19 at 03:30

Just implement a TextWatcher on your editText and inside its onTextChanged() method implements a simple if condition to check if space is entered or not and then replace that space with % if the condition is true.

try this,

editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            if (charSequence.toString().equalsIgnoreCase(" ")) {
                editText.setText(charSequence.toString().replace(" ", "%"));
            }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    });
