Solution 1:

Implement the TextWatcher on your edittext like this

EditTextmyTextBox= (EditText) findViewById(R.id.myTextBox);
  myTextBox.addTextChangedListener(newTextWatcher() {

   publicvoidafterTextChanged(Editable s) {
   }

   publicvoidbeforeTextChanged(CharSequence s, int start, 
     int count, int after) {
   }

   publicvoidonTextChanged(CharSequence s, int start, 
     int before, int count) {
   // Here you can trigger your another code/function about which you are asking
   }
  });

Hope it will help!

Solution 2:

you can use OnFocusChangeListener, if the textview has focus then the user is typing. for more information you can check here http://developer.android.com/reference/android/view/View.OnFocusChangeListener.html
