Try implementing TextWatcher interface.

It has three methods which you need to override.

public void afterTextChanged(Editable s) {
        
        Log.v("afterTextChanged","here");
    }
    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
        
        Log.v("beforeTextChanged","here");
    }
    
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        }

I think this will do your work.
