The most basic way to do this would be to simply reset your EditText views. If you have logic that drives the update of these fields, then resetting them to an empty String and requesting a "recalculation" to update the hints.

{
    EditText firstField = (EditText)this.findById(R.id.firstField);
    EditText secondField = (EditText)this.findById(R.id.secondField);
    //...etc...
    if (firstField != null) firstField.setText("");
    if (secondField != null) secondField.setText("");

    updateHints();
}

private void updateHints()
{
    //Logic for your "hints"
}
