以下是一个示例代码，演示了如何比较两个ListView的父项和子项，并改变图片索引:

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.widget.ImageView;
import android.widget.TextView;

public class MainActivity extends Activity {

    private ExpandableListView listView1, listView2;
    private List listDataHeader1, listDataHeader2;
    private Map> listDataChild1, listDataChild2;
    private MyExpandableListAdapter adapter1, adapter2;

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

        // 初始化数据
        initData();

        // 初始化ListView
        listView1 = (ExpandableListView) findViewById(R.id.listView1);
        listView2 = (ExpandableListView) findViewById(R.id.listView2);

        adapter1 = new MyExpandableListAdapter(listDataHeader1, listDataChild1);

        // 设置适配器
        listView1.setAdapter(adapter1);
        listView2.setAdapter(adapter2);

        // 处理父项点击事件
        listView1.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {

                }

                // 更新图片索引
                imageView.setTag(imageIndex);
                imageView.setImageResource(getImageResource(imageIndex));

                return false;

                } else {
                    imageIndex = 0;
                }

                imageView.setTag(imageIndex);
                imageView.setImageResource(getImageResource(imageIndex));
