コードでエラーが発生し続けます。AlertDialog 内で新しい AlertDialog を呼び出そうとしています。サルトの表示に問題があるようですが、理由がわかりません...

public String passA = "";
public String passB = "";

public void createPassword() {
    final AlertDialog.Builder alert = new AlertDialog.Builder(this);
    final AlertDialog.Builder salert = new AlertDialog.Builder(this);
    final EditText input = new EditText(this);
    input.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD
            | InputType.TYPE_CLASS_TEXT);

    salert.setView(input); // edit text added to alert
    alert.setView(input); // edit text added to alert
    salert.setTitle("Widerholen Sie Ihre PIN"); // title setted
    alert.setTitle("Geben Sie eine PIN an"); // title setted

    final OnClickListener b = new OnClickListener() {
        public void onClick(DialogInterface arg0, int arg1) {
            passB = input.getText().toString();
            if (passA.equals(passB)) {
                editor = settings.edit();
                editor.putString("password", passA);
                editor.commit();
                logged_in = true;
                return;
            }
        }
    };
    salert.setPositiveButton("OK", b);

    OnClickListener a = new OnClickListener() {
        public void onClick(DialogInterface arg0, int arg1) {
            passA = input.getText().toString();

            salert.show();
            return;
        }
    };

    alert.setPositiveButton("OK", a);

    alert.setOnCancelListener(new OnCancelListener() {

        public void onCancel(DialogInterface dialog) {
            // TODO Auto-generated method stub
            Functions.writeError("Falsche PIN Eingabe.");
            finish();
        }

    });
    alert.show();
}

私が得ているエラーは次のとおりです。

複数のダイアログに 1 つのビューを使用しています。1 つのビューは 1 つの親を持つことができます。

変化する：

final EditText input = new EditText(this);

salert.setView(input); // edit text added to alert
alert.setView(input); // edit text added to alert

に：

final EditText firstInput = new EditText(this);
final EditText secondInput = new EditText(this);

salert.setView(firstInput); // edit text added to alert
alert.setView(secondInput); // edit text added to alert
