我有一个片段内的listView（ListFragment不适用，因为有视图中的其他控件）。 它运行正常，但列表未填充。 日志和调试显示，适配器的getView被调用，一切都很好。只是没有显示。在片段中的listView不工作（不显示）
这里是片段
public class FoundFragment extends BaseFragment {
private ArrayList<Record> recordsList;
private ListView recordsListView;
private final String LOG_TAG = "FoundFragment";
private RecordsListAdapter recordsListAdapter;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}//end onCreate
//----------------------------------------------------------------------------------//
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
// The last two arguments ensure LayoutParams are inflated properly.
View rootView = inflater.inflate(
R.layout.frag_found, container, false);
return rootView;
}//end onCreateView
//------------------------------------------------------------------------------------//
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
recordsListView = (ListView) getView().findViewById(R.id.foundRecordsListView);
}
//------------------------------------------------------------------------------------//
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
new RecordsLoaderTask().execute(false);
}
//------------------------------------------------------------------------------------//
@Override
public void onResume() {
super.onResume();
if(recordsListAdapter != null){
recordsListAdapter.notifyDataSetChanged();
}
}
/********************************************************************/
@SuppressWarnings("unchecked")
@Override
public void onDataRetrievalSucceeded(Object dataRetrieved) {
Log.d("FoundFragment", "arrayRetrived with length of "
+ ((ArrayList<Record>) dataRetrieved).size());
recordsList = (ArrayList<Record>) dataRetrieved;
recordsListAdapter = new RecordsListAdapter(getActivity(), recordsList);
recordsListView.setAdapter(recordsListAdapter);
Log.e(LOG_TAG, "adapterOfList is " + recordsListView.getAdapter() + "\n" +
"length is " + recordsListView.getAdapter().getCount());
//TODO check here
if(recordsListAdapter != null){
recordsListAdapter.notifyDataSetChanged();
}
}//end onDataRetrievalSucceeded
}//end fragment
适配器：
private class RecordsListAdapter extends BaseAdapter{
private LayoutInflater mInflater;
private ArrayList<Record> recsList;
//--------------------------------------------------------------------//
public RecordsListAdapter(Context context, ArrayList<Record> records) {
// Cache the LayoutInflate to avoid asking for a new one each time.
System.out.println("in constructor of adaapter");
mInflater = LayoutInflater.from(context);
recsList = records;
}
//--------------------------------------------------------------------//
@Override
public int getCount() {
Log.d(LOG_TAG, "categories adapter get size = " + recsList.size());
return recsList.size();
}
//--------------------------------------------------------------------//
@Override
public Object getItem(int position) {
return recsList.get(position);
}
//--------------------------------------------------------------------//
@Override
public long getItemId(int position) {
return position;
}
//--------------------------------------------------------------------//
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null){
convertView = mInflater.inflate(R.layout.records_list_item, parent, false);
holder = new ViewHolder();
holder.name = (TextView) convertView.findViewById(R.id.recordItemNameTxtView);
holder.age = (TextView) convertView.findViewById(R.id.recordItemAgeTxtView);
holder.img = (CircularImageView) convertView.findViewById(R.id.recordItemImgView);
convertView.setTag(holder);
}//end if
else{
holder = (ViewHolder) convertView.getTag();
}
Record curRecord = recsList.get(position);
/*setting data from the item into the fields*/;
holder.name.setText(curRecord.getName());
holder.age.setText(curRecord.getAge());
Log.d(LOG_TAG, "curRecord image link is " + curRecord.getThumbURL());
//TODO image download
/*if(curRecord.getThumbURL() != null && !curRecord.getThumbURL().equals("")
&& !curRecord.getThumbURL().equals("null")){
Log.d(LOG_TAG, "in if b4 download image");
holder.img.setImageBitmap(
ImageDownloader.DownloadImage(curRecord.getThumbURL()));
progressDialog.cancel();
System.out.println("after image download");
}//end if --> imag link is available
else{
System.out.println("image link is not available");
}*/
Log.w(LOG_TAG, "convertView " +
convertView + ", " + ((ViewHolder)convertView.getTag()).name.getText().toString());
return convertView;
}//end method getView
////////////////////////////////////////////////////////////////////////////////////

同样的事情。尝试之前并没有工作 – Rowan 2015-02-10 12:31:22
