我收到了一个错误的错误。我从sqlite db获取人员信息。用光标取整个表然后放入arraylist。信息包括姓名，公司，职位，地址，电话，手机，电子邮件和照片（以字节为单位）。这是代码：
public class Contacts extends ListActivity {
private ArrayList<Stuff> contactsList = null;
private ContactsAdapter contactsAdapter;
private ProgressDialog m_ProgressDialog = null;
private Runnable viewContacts;
// Attributes
private static String name = "";
private static String company = "";
private static String title = "";
private static String address = "";
private static String phone = "";
private static String cel = "";
private static String email = "";
private static byte[] picture = null;
private static int template = 0;
@SuppressWarnings("unchecked")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contact_list);
contactsList = new ArrayList<Stuff>();
contactsAdapter = new ContactsAdapter(this,
R.layout.contact_list_entry, contactsList);
setListAdapter(this.contactsAdapter);
// Setting progress dialog
viewContacts = new Runnable() {
public void run() {
getOrders();
}
};
Thread thread = new Thread(null, viewContacts, "MagentoBackground");
thread.start();
m_ProgressDialog = ProgressDialog.show(Contacts.this, "Please wait...",
"Retrieving data ...", true);
/*
*
* Log.d("*********", "size :" + Integer.toString(contactsList.size()));
*
* if (contactsList != null && !contactsList.isEmpty()) {
*
* contactsAdapter.notifyDataSetChanged(); contactsAdapter.clear(); for
* (int i = 0; i < contactsList.size(); i++) {
* contactsAdapter.add(contactsList.get(i)); } }
*
* contactsAdapter.notifyDataSetChanged();
*/
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
Stuff stuff = contactsList.get(position);
Intent i = new Intent(Contacts.this, ContactsDetail.class);
Bundle bundle = new Bundle();
bundle.putSerializable("person", stuff);
i.putExtra("personBundle", bundle);
startActivity(i);
}
private Runnable returnRes = new Runnable() {
public void run() {
// Get Data from database
CardsDatabase info = new CardsDatabase(Contacts.this);
info.open();
Cursor c = info.geTContactsData();
c.moveToFirst();
while (c.isAfterLast() == false) {
name = c.getString(c.getColumnIndex(CardsDatabase.NAME_R));
company = c
.getString(c.getColumnIndex(CardsDatabase.COMPANY_R));

email, template, null, true);
contactsList.add(s);
c.moveToNext();
}
c.close();
info.close();
if (contactsList != null && contactsList.size() > 0) {
contactsAdapter.notifyDataSetChanged();
for (int i = 0; i < contactsList.size(); i++)
contactsAdapter.add(contactsList.get(i));
}
m_ProgressDialog.dismiss();
contactsAdapter.notifyDataSetChanged();
}
};
private void getOrders() {
runOnUiThread(returnRes);
}
}
我使用的这个自定义适配器：
public class ContactsAdapter extends ArrayAdapter<Stuff> {
private ArrayList<Stuff> contactDataItems;
private Activity context;
public ContactsAdapter(Activity context, int textViewResourceId,
ArrayList<Stuff> contactDataItems) {
super(context, textViewResourceId, contactDataItems);
this.context = context;
this.contactDataItems = contactDataItems;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater vi = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(R.layout.contact_list_entry, null);
}
Stuff stuff = contactDataItems.get(position);
if (stuff != null) {
// name
TextView nameTextView = (TextView) view
.findViewById(R.id.contact_name);
nameTextView.setText(stuff.getName());
// number
TextView ratingTextView = (TextView) view
.findViewById(R.id.contact_number);
ratingTextView.setText("Rating: " + stuff.getPhone());
// thumb image
ImageView imageView = (ImageView) view
.findViewById(R.id.contact_pic);
final Bitmap bitmap;
byte[] picture = stuff.getPicture();
ByteArrayOutputStream bos = new ByteArrayOutputStream();
if (picture != null) {
ByteArrayInputStream imageStream = new ByteArrayInputStream(
picture);
bitmap = BitmapFactory.decodeStream(imageStream);
Log.d("populate", "stored pic");
} else {
bitmap = BitmapFactory.decodeResource(Resources.getSystem(),
R.drawable.default_pic);
bitmap.compress(CompressFormat.PNG, 0, bos);
picture = bos.toByteArray();
Log.d("populate", "default pic");
}
imageView.setImageBitmap(bitmap);
}
return view;
}
}
