Answer 1

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.

Answer 2

try implementing TextWatcher interface.

it has 3 methods which u 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 ur work.
