How to know key presses in EditText

Question

I need to detect every key press on either a soft or hard keyboard in EditText. I just need to send the characters one at a time as they are pressed and don't need the final text string.

I have tried using an EditText with onKeyPress, but I ran into the problems here with not getting key presses with soft keyboards and TextWatcher isn't a good option because I need each key press. Is there any solution to know all the keypresses (including back, shift, enter... also)?

If you have an EditText, then you can use the TextWatcher interface. In my code, search_edit is an EditText.

search_edit.addTextChangedListener(new TextWatcher() {               @Override     public void onTextChanged(CharSequence s, int start, int before, int count) {                                            //here is your code         myadapter.getFilter().filter(s);         listview.setAdapter(myadapter);      }                            @Override     public void beforeTextChanged(CharSequence s, int start, int count, int after) {         // TODO Auto-generated method stub                               }                            @Override     public void afterTextChanged(Editable s) {         // TODO Auto-generated method stub                       } });

Implement this:

 et_code_1.setOnKeyListener(new View.OnKeyListener() {             @Override             public boolean onKey(View v, int keyCode, KeyEvent event) {                 if (keyCode == KeyEvent.KEYCODE_ENTER) {                     /* do something */                 }             return true;             }         }); 

Update:

As you would like to implement a Soft key listener, you can implement TextWatcher. Here is an example: How to use the TextWatcher class in Android?
