我有一個帶有3個EditText的對話框,用於獲取ftp地址,用戶名和密碼。我使用.setNeutralButton來創建一個按鈕來「測試連接」。我把它連接到ftp並顯示結果Toast,但我不想讓測試按鈕關閉對話框。如何在連接測試期間保持對話框打開?單擊中性按鈕後是否可以保持對話框打開?

serverName.setHint("Server name");
final EditText serverAddress = new EditText(NewSite.this);
serverAddress.setHint("Server Address");
final EditText username = new EditText(NewSite.this);
username.setHint("Username:");
final EditText password = new EditText(NewSite.this);
password.setHint("Password");

// if this button is clicked, just close

lila1.addView(serverName);

alert.setView(lila1);
alert.show();
}
