如何在Android的多选对话框中保留旋转时的选择？

public class MainActivity extends AppCompatActivity {
    private boolean[] checkedItems; // 保存选中状态的数组

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 初始化选中状态数组
        checkedItems = new boolean[3];
        Arrays.fill(checkedItems, false);

        // 显示多选对话框
        showMultiChoiceDialog();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);

        // 屏幕旋转后重新设置选中状态
        showMultiChoiceDialog();
    }

    private void showMultiChoiceDialog() {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("多选对话框");
        builder.setMultiChoiceItems(R.array.items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                // 更新选中状态数组
                checkedItems[which] = isChecked;
            }
        });
        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 处理确定按钮点击事件
            }
        });
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                // 处理取消按钮点击事件
            }
        });
        builder.show();
    }
}
