如何使文本从EditText在AlertDialog可在MainActivity类

Question

在我的项目中有一个MainActivity类和victory()方法:

public void victory() {
        name = "";
        AlertDialog dialog = DialogScreen.getDialog(this, DialogScreen.IDD_MAPHIGHSCORE);
        dialog.setCanceledOnTouchOutside(false);
        dialog.show();
        name = DialogScreen.nickname;
        Log.i("NICKNAME :", " " + name);
    }

我从DialogScreen类调用getDialog(Activity Activity, int ID)方法:

public class DialogScreen {
static String nickname = "DEF";
public static final int IDD_MAPHIGHSCORE = 1;
public static final int IDD_WORLDHIGHSCORE = 2;
public static AlertDialog getDialog(Activity activity, int ID) {
    AlertDialog.Builder builder = new AlertDialog.Builder(activity);
    final EditText editText = new EditText(activity);
    int maxLength = 15;
    editText.setFilters(new InputFilter[] {new InputFilter.LengthFilter(maxLength)});
    switch(ID) {
        case IDD_MAPHIGHSCORE: {
            builder.setTitle(R.string.newHighScore);
            builder.setMessage(R.string.enterNickName);
            builder.setCancelable(true);
            builder.setView(editText).create();
            builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    String text = editText.getText().toString();
                    nickname  = text;
                    dialog.dismiss();
                }
            });
        }
    }
    return builder.create();
}

}

但是在Log中。如果我只能看到"昵称:"。我还尝试了DialogScreen类中的getter和MainActivity类中的setter。但这没有用。

所以第一个问题是如何使文本从EditText在MainActivity类可用?

第二个是我怎么知道(从MainActivity类)，如果按钮"OK"从对话框已被按下?

我想这是一个时间问题日志。在您单击对话框的肯定按钮之前完成。在MainActivity和移动日志的对话框中添加一个解散监听器。
