java - 在警报对话框中访问 LinearLayout 中的 EditText

Question

我有这个代码:

final AlertDialog.Builder alert = new AlertDialog.Builder(this);
final EditText name = new EditText(this);
final EditText surname = new EditText(this);
final EditText email = new EditText(this);
LinearLayout ll=new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.addView(image);
ll.addView(name);
ll.addView(surname);
ll.addView(email);
alert.setView(ll);
alert.setPositiveButton(R.string.enter, new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
        String name = // ??
        String surname = // ??
        String email = // ??
    }
});
alert.show();

如何获取在 OnClickListener 内的 EditText 字段中输入的文本字符串？
