如何在安卓系统中用ViewPager显示ListView选中的项目

<androidx.viewpager.widget.ViewPager
    android:id="@+id/viewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

ListView listView = findViewById(R.id.listView);
List<String> data = getData(); // 获取数据源
ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, data);
listView.setAdapter(adapter);

ViewPager viewPager = findViewById(R.id.viewPager);
ViewPagerAdapter pagerAdapter = new ViewPagerAdapter();
viewPager.setAdapter(pagerAdapter);

class ViewPagerAdapter extends PagerAdapter {
    @Override
    public int getCount() {
        return data.size(); // 页面数量与ListView的数据项数量一致
    }

    @Override
    public boolean isViewFromObject(@NonNull View view, @NonNull Object object) {
        return view == object;
    }

    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
        View view = LayoutInflater.from(container.getContext()).inflate(R.layout.page_item, container, false);
        ListView listView = view.findViewById(R.id.listView);
        listView.setAdapter(adapter); // 使用相同的适配器
        listView.setSelection(position); // 设置ListView选中项
        container.addView(view);
        return view;
    }

    @Override
    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
        container.removeView((View) object);
    }
}

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
