Lorsque j'essaie d'intégrer sherlock de barre d'action dans mon projet existant, il se bloque au démarrage. Toutefois, la barre d'actions et mon projet fonctionnaient avant la compilation.Le fragment Android se bloque au démarrage
Voici mon code fragment:
public class SalesOrder extends SherlockFragment{
ListView myInfoList;
String[] items = {"Item 1", "Item 2"};
ArrayAdapter<CharSequence> adapter;
ArrayList<MessageDetails> details;
AdapterView.AdapterContextMenuInfo info;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
refreshListView();
return inflater.inflate(R.layout.sales_order, container, false);
}
private void refreshListView()
{
myInfoList = (ListView)getActivity().findViewById(R.id.MessageList);
adapter = new ArrayAdapter<CharSequence>(getActivity().getApplicationContext(), android.R.layout.simple_list_item_1, items);
myInfoList.setAdapter(adapter);
details = new ArrayList<MessageDetails>();
MessageDetails Detail;
//CHANGE THIS PART TO RETRIEVE DATABASE ITEM DYNAMICALLY
List<String> itemName = new ArrayList<String>();
itemName.add("Shirt Design 1");
itemName.add("Shirt Design 2");
itemName.add("Shirt Design 3");
List<Float> itemPrice = new ArrayList<Float>();
itemPrice.add(14f);
itemPrice.add(15f);
itemPrice.add(16f);
List<String> description = new ArrayList<String>();
description.add("This is a fine shirt 1");
description.add("This is a fine shirt 2");
description.add("This is a fine shirt 3");
Detail = new MessageDetails();
for (int i =0; i < itemName.size(); i++)
{
Detail = new MessageDetails();
Detail.setSub(itemName.get(i));
Detail.setSubValue(itemPrice.get(i));
Detail.setDescription(description.get(i));
details.add(Detail);
}
myInfoList.setAdapter(new CustomAdapter(details , getActivity().getApplicationContext()));
myInfoList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
//System.out.println("Name: "+details.get(position).getSub());
String s = details.get(position).getDescription();
}
});
}
public class CustomAdapter extends BaseAdapter {
private ArrayList<MessageDetails> _data;
Context _c;
CustomAdapter (ArrayList<MessageDetails> data, Context c){
_data = data;
_c = c;
}
public int getCount() {
// TODO Auto-generated method stub
return _data.size();
}
public Object getItem(int position) {
// TODO Auto-generated method stub
return _data.get(position);
}
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = convertView;
if (v == null)
{
LayoutInflater vi = (LayoutInflater)_c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.mysaleslistview, null);
}
TextView subView = (TextView)v.findViewById(R.id.itemName);
TextView subValueView = (TextView)v.findViewById(R.id.itemPrice);
MessageDetails msg = _data.get(position);
subView.setText(msg.sub);
subValueView.setText(msg.subValue.toString());
return v;
}
}
public class MessageDetails {
String sub, description;
Float subValue;
public String getSub() {
return sub;
}
public void setSub(String sub) {
this.sub = sub;
}
public Float getSubValue() {
return subValue;
}
public void setSubValue(Float subValue) {
this.subValue = subValue;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
}
Et mon logcat:

À quoi correspond la ligne 38? – Ahmad
myInfoList.setAdapter (adaptateur); –
@Ahmad a raison: vous avez une exception 'NullPointerException' sur la ligne 38, à l'intérieur de votre méthode' refreshListView() '. – eternay
