android - 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                  
    }
});
