我将必要的代码放在OnResume()中，而不是OnCreate()中，但是当我转到不同的活动时，ListView中的数组数据仍然会消失

public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private ArrayAdapter<String> adapter;
    private String[] dataArray;

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

        listView = findViewById(R.id.listView);

        if (savedInstanceState != null) {
            dataArray = savedInstanceState.getStringArray("dataArray");
        } else {
            // 初始化数组数据
            dataArray = new String[]{"Item 1", "Item 2", "Item 3"};
        }

        adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, dataArray);
        listView.setAdapter(adapter);
    }

    @Override
    protected void onResume() {
        super.onResume();
        // 更新数组数据
        dataArray = new String[]{"Item 4", "Item 5", "Item 6"};
        adapter.notifyDataSetChanged();
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        // 保存数组数据
        outState.putStringArray("dataArray", dataArray);
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        // 恢复数组数据
        dataArray = savedInstanceState.getStringArray("dataArray");
        adapter.notifyDataSetChanged();
    }
}
