在网上也看了很多相关文章了,还是没有解决,在Activity下使用此代码没有任何问题，数据可以显示，但是用了Fragment adapter的getView方法就一直不执行。
我觉得他们之间唯一的区别的就是context 和view 的不同，请大神指教
代码如下
public class BookSearchActivity extends Fragment {
private BookSearchService service;
private List<Books> list;
private String result;
private BookSearchAdapter adapter;
private Handler mHandler;
private ListView listView;
private View v ;
private Context context;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
context= getActivity();
v = inflater.inflate(R.layout.booksearch, container, false);
return inflater.inflate(R.layout.booksearch, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mHandler = new Handler();
new Thread(new Runnable() {
@Override
public void run() {
service = new BookSearchService();
list = service.queryBookList("", "");
if (list == null)
result = ApplConst.FAILURE;
else
result = ApplConst.SUCCESS;
adapter = new BookSearchAdapter(list,context);
mHandler.post(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
listView = ((ListView) v.findViewById(R.id.books_list_view));
listView.setAdapter(adapter);
listView.setDividerHeight(1); // 不显示分割线
listView.setCacheColorHint(Color.TRANSPARENT); //防止listview背景变黑
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent,
View view, int position, long id) {
Intent newActivity = new Intent(view.getContext(),
BookSearchActivity.class);
Books book = (Books) listView.getItemAtPosition(position);
newActivity.putExtra("BookId",
book.getId());
newActivity.putExtra("categoryId",
book.getCategoryId());
startActivity(newActivity);
}
});
}
});
}
}).start();
}
}

private Map<Integer, View> rowViews = new HashMap<Integer, View>();
private Context context = null;
public BookSearchAdapter(List<Books> objects, Context context) {
booksList = objects;
this.context = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = rowViews.get(position);
if (rowView == null) {
SimpleDateFormat df = new SimpleDateFormat("HH:mm:ss");
LayoutInflater layoutInflater = LayoutInflater.from(context);
rowView = layoutInflater.inflate(R.layout.booksearch_items,
null);

Books books = booksList.get(position);
if (books.publicationDate != null)
publicationDate.setText("出版时间:"
+ DateUtil.parseDateToString(
books.getPublicationDate(), df));
if(books.getBookName()!=null)
bookName.setText(books.getBookName());
if(books.getWritor()!=null)
writor.setText("编者:"+books.getWritor());
if(books.getBookName()!=null)
publish.setText("出版社:"+books.getPublish());
rowViews.put(position, rowView);
}
return rowView;
}
