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.

Take a Look at AutoCompleteTextView.

Basically you can create an ArrayAdapter or a SimpleAdapter that contains your Strings. Then just replace your EditText with the AutoCompleteTextView and automagically ... you get the typeahead behavior that you describe.

AutocompleteTextView will create TextView list that has all the possible words that match your strings. Is this what you want?
