Android 自訂對話框控件取得方法

若要使用自定義的對話框，要使用到裡面的控件時，要像下面這樣使用。

LayoutInflater factory = LayoutInflater.from(DrawPanel.this);     final View textEntryView = factory.inflate(R.layout.remote,             null);     AlertDialog dlg = new AlertDialog.Builder(DrawPanel.this)             .setTitle("User Login")             .setView(textEntryView)             .setPositiveButton("OK",                     new DialogInterface.OnClickListener() {                         public void onClick(DialogInterface dialog,                                 int whichButton) {                             final EditText user = (EditText) textEntryView.findViewById(R.id.userName);                             final EditText serverName = (EditText)textEntryView.findViewById(R.id.serverName);                             final EditText serverPort = (EditText)textEntryView.findViewById(R.id.serverPort);                             String username = user.getText().toString();                             String hostAddress = serverName.getText().toString();                             String port = serverPort.getText().toString();
