我有一个AlertDialog将数组显示为单个选定选项的方法:

    protected boolean blFrom, blTo;
protected void showSelectToDialog() {
    boolean[] checkedDate = new boolean[toDate.length];
    int count = toDate.length;

    DialogInterface.OnClickListener setD2 = new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            //TODO Auto-generated method stub
            onChangeSelectedTo(which);
        }
    };

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Select To Year");
    builder.setSingleChoiceItems(toDate, count, setD2);

    builder.setCancelable(true);
    builder.setPositiveButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            dialog.dismiss();
        }
    });
    dialog2 = builder.create();
    dialog2.show();
}

protected void onChangeSelectedTo(int j) {
    bTo.setText(toDate[j]);
    sTo = ((AlertDialog)dialog2).getListView().getCheckedItemPosition();
    blTo = true;
    displayToast(String.valueOf(sTo));
    to = j;
    dialog.dismiss();
}

我想要做的是第一次加载它应该显示默认值。一旦我选择了一个选项并且对话框关闭并且我再次打开相同的对话框,它应该显示我之前选择的选项并滚动到它。

我该如何完成它?

截至目前,我可以获得选定的职位,但接下来呢?

您可以将所选值存储在您的变量中Activity或使用SharedPreferences
