请查看商店中的Contacts + app以了解我的意思。您有三个ListView,每个都有屏幕宽度。然后,您可以使用HorizontalScrollView滚动每个。最好的方法是什么?

您可以使用带有三个片段的viewpager作为标签,使用标签适配器,如下所示。
主持人活动:
public class PageViewActivity extends FragmentActivity {
MyPageAdapter pageAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page_view);
List<Fragment> fragments = getFragments();
pageAdapter = new MyPageAdapter(getSupportFragmentManager(), fragments);
ViewPager pager =
(ViewPager)findViewById(R.id.viewpager);
pager.setAdapter(pageAdapter);
}
}
片段适配器
class MyPageAdapter extends FragmentPagerAdapter {
private List<Fragment> fragments;
public MyPageAdapter(FragmentManager fm, List<Fragment> fragments) {
super(fm);
this.fragments = fragments;
}
@Override
public Fragment getItem(int position) {
return this.fragments.get(position);
}
@Override
public int getCount() {
return this.fragments.size();
}
}
获取片段的方法(可选取决于您希望如何使用片段)
private List<Fragment> getFragments(){
List<Fragment> fList = new ArrayList<Fragment>();
fList.add(MyFragment.newInstance("Fragment 1"));
fList.add(MyFragment.newInstance("Fragment 2"));
fList.add(MyFragment.newInstance("Fragment 3"));
return fList;
你的片段类
public class MyFragment extends Fragment {
public static final String EXTRA_MESSAGE = "EXTRA_MESSAGE";
public static final MyFragment newInstance(String message)
{
MyFragment f = new MyFragment();
Bundle bdl = new Bundle(1);
bdl.putString(EXTRA_MESSAGE, message);
f.setArguments(bdl);
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String message = getArguments().getString(EXTRA_MESSAGE);
View v = inflater.inflate(R.layout.myfragment_layout, container, false);
TextView messageTextView = (TextView)v.findViewById(R.id.textView);
messageTextView.setText(message);
return v;
}
}
