Answer 1

Just do like this –

((EditText)findViewById(R.id.et_testo)).addTextChangedListener(new TextWatcher() {

public void afterTextChanged(Editable s) {

}

public void beforeTextChanged(CharSequence s, int start, int count,
        int after) {
    // TODO Auto-generated method stub

}

public void onTextChanged(CharSequence s, int start, int before,
        int count) {
    // TODO Auto-generated method stub
    Toast.makeToast(activity.this, s.toString(), Toast.Long).show();
}
});

Have a look at TextWatcher
