需要一些帮助设计在Android中的布局
我有ListView使用AsyncTask从服务器获取数据。之后onItemClick开始新Activity，该ListView应显示ViewPager中所点击项目的更详细信息。很简单。但问题是单个页面应该像9GAG android app一样工作（即带有ViewPager的可滑动片段）。详细信息更多。您对该页面的设计布局有何建议？目前我在该单页上使用public class IndividualPage extends ActionBarActivity{
ArrayList<Item> arrayOfList;
ViewPager pager;
CountryPageAdapter pageAdapter;
private ProgressBar mProgress;
@Override
public void onCreate (Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.secondpage);
mProgress = (ProgressBar) findViewById(R.id.linear_progress_bar);
new FilteredResult().execute();
pager = (ViewPager)findViewById(R.id.viewpager);
}
private List<Fragment> getFragments() {
List<Fragment> frags = new ArrayList<Fragment>();
System.out.println("fragments main ayya hai");
cats=arrayOfList;
for(int i = 0;i<cats.size();i++ ) {
System.out.println("number : "+i+"::"+cats.get(i).getSector());
frags.add(prepareFragment(cats.get(i).getImage(),cats.get(i).getName(),cats.get(i).getLocation(),cats.get(i).getSector(),cats.get(i).getStatus(),cats.get(i).getFounded(),cats.get(i).getFundRaising()));
}
return frags;
}
Fragment prepareFragment(String image,String name,String location,String Expertise,String sector,int founded,String fund) {
CountryFragment cf = new CountryFragment();
Bundle args = new Bundle();
args.putString(CountryFragment.STARTUP_IMAGE, image);
args.putString(CountryFragment.STARTUP_NAME, name);
args.putString(CountryFragment.STARTUP_LOCATION, location);
args.putString(CountryFragment.STARTUP_EXP, Expertise);
args.putString(CountryFragment.STARTUP_SEC, sector);
args.putInt(CountryFragment.STARTUP_FOUNDED, founded);
args.putString(CountryFragment.STARTUP_FUND, fund);
cf.setArguments(args);
return cf;
}
[![public class FilteredResult extends AsyncTask<String, Void, String> {
//onpreexcute nothing doing great in this
//onbackground
@Override
protected void onPostExecute(String result) {
List<Fragment> fragments = getFragments();
pageAdapter = new CountryPageAdapter(getSupportFragmentManager(), fragments);
pager.setAdapter(pageAdapter);
}
}]
并设计片段以获得所需的内容。
代码
<item name="android:listSelector">?attr/listChoiceBackgroundIndicator</item>

答案 0 :(得分：1)
我个人更喜欢ViewPagers到ScrollViews，因为他们没有将所有片段/视图保留在内存中。
此外，每个单独的项目都独立于其他项目。例如，如果您希望能够为每个项目实现垂直滚动，则无法使用HorizontalScrollView执行此操作，因为所有视图都将一起滚动。
