enter image description hereenter image description here谁能告诉我在哪里写listView的代码以便活动扩展片段可以读取它。有onCreateView，我映射listview但仍然没有读取它。
正如你所看到的，我评论的方法很少，因为它没有阅读它。请告诉我在哪里编写代码以获得输出。以下是我的代码。
public class Tab1 extends Fragment {
PendingPickupBEAN pendingPickup=new PendingPickupBEAN();
public static final List<PendingPickupBEAN> refer=new ArrayList<PendingPickupBEAN>();
ListView listview;
CustomListView customListView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*listview= (ListView) findViewById(R.id.listTab1);
customListView = new CustomListView(getContext(),R.layout.list_item,DashboardActivity.listBeanobj);
Log.e(TAG,"=======CUSTOM LIST VIEW ========");
listview.setAdapter(customListView);*/
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// final ArrayList<PendingPickupBEAN> listPending = (ArrayList<PendingPickupBEAN>) getIntent().getSerializableExtra("ARRAYLIST");
Log.e(TAG,"Pending piclup list : listbeanobj " + DashboardActivity.listBeanobj.size());
View view= inflater.inflate(R.layout.activity_tab1, container, false);
return view;
listview=(ListView) view.findViewById(R.id.listTab1);
customListView = new CustomListView(getContext(),R.layout.list_item,DashboardActivity.listBeanobj);
Log.e(TAG,"=======CUSTOM LIST VIEW ========");
listview.setAdapter(customListView);
}
public class CustomListView extends ArrayAdapter<PendingPickupBEAN> {
/* ArrayAdapter<PendingPickupBEAN> adapter=new ArrayAdapter<PendingPickupBEAN>

我做到了。但它显示空白活动。没有预期的输出。
