我想为列表设置自定义布局，但它有例外.
I want to set my custom layout for list, but it makes exceptions.
代码如下:
public class ListFragmentActivity extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
FragmentManager fm = getSupportFragmentManager();
if(fm.findFragmentById(android.R.id.content) == null)
{
myListFragments list = new myListFragments();
fm.beginTransaction().add(android.R.id.content, list).commit();
}
}
public static class myListFragments extends ListFragment
{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.topoffers, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
List<OfferModel> offers = Global.getInstance().getOffers();
List<OfferModel> topOffers = new ArrayList<OfferModel>(4);
for (int i = 0; i < 4; i++) {
if (offers.get(i).getOfferImage() == null)
offers.get(i).setOfferImage(
downloadFile(offers.get(i).getOfferImageUrl()));
topOffers.add(offers.get(i));
}
LazyAdapter adapter = new LazyAdapter(getActivity());
adapter.setData(topOffers);
setListAdapter(adapter);
setListShown(true);
}
public Bitmap downloadFile(String fileUrl) {
URL myFileUrl = null;
try {
myFileUrl = new URL(fileUrl);
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
}
try {
HttpURLConnection conn = (HttpURLConnection) myFileUrl
.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
return BitmapFactory.decodeStream(is);
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
}}
我的自定义布局是 R.layout.topoffers
