Android setOnEditorActionListener（）不会触发

您可以使用TextWatcher。

    editText.addTextChangedListener(new TextWatcher() {        @Override        public void onTextChanged(CharSequence s, int start, int before, int count) {        }        @Override        public void beforeTextChanged(CharSequence s, int start, int count,     int after) {        }        @Override        public void afterTextChanged(Editable s) { if (s.charAt(s.length() - 1) == 'n') {       Log.d("TEST RESPONSE", "Enter was pressed"); }        }    });
