如何为我的ListView保存滚动位置

public class MyActivity extends AppCompatActivity {
    private ListView listView;
    private int lastVisibleItemPosition = 0;

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

        listView = findViewById(R.id.listView);

        // 设置ListView的滚动监听器
        listView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {
                // 滚动停止时保存当前可见的第一个item的位置
                if (scrollState == AbsListView.OnScrollListener.SCROLL_STATE_IDLE) {
                    View firstVisibleItem = listView.getChildAt(0);
                    lastVisibleItemPosition = listView.getFirstVisiblePosition();
                    if (firstVisibleItem != null) {
                        lastVisibleItemPosition += firstVisibleItem.getTop() / firstVisibleItem.getHeight();
                    }
                }
            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                // 滚动中的逻辑处理
            }
        });

        // 恢复滚动位置
        if (savedInstanceState != null) {
            lastVisibleItemPosition = savedInstanceState.getInt("lastVisibleItemPosition");
        }
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        // 保存滚动位置
        outState.putInt("lastVisibleItemPosition", lastVisibleItemPosition);
    }

    @Override
    protected void onResume() {
        super.onResume();
        // 恢复滚动位置
        listView.setSelection(lastVisibleItemPosition);
    }
}
