我正在导入联系人并将其显示在 ListView 中。
这是我的光标加载器
ContentResolver cr = getActivity().getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
mAdapter = new ContactsAdapter(getActivity(), cur, true, null);
setListAdapter(mAdapter);
我的适配器是
for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()) {
// do what you need with the cursor here
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
Log.e("name", name + "\n" + cursor.getCount());
names.add(name);
}
getIndexList();
这是我的绑定(bind) View
@Override
public void bindView(View view, Context context, Cursor cursor) {
// Gets handles to individual view resources
final ViewHolder holder = (ViewHolder) view.getTag();
String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
for (phoneCursor.moveToFirst(); !phoneCursor.isAfterLast(); phoneCursor.moveToNext()) {
// do what you need with the cursor here
String phoneNum = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.e("phoneNum", phoneNum);
mCheckBox.setTag(phoneNum);
if (selectedNums.contains(phoneNum)) {
mCheckBox.setChecked(true);
} else {
mCheckBox.setChecked(false);
}
}
当 ListView 到达末尾时，我的代码崩溃了。如果有 2 个联系人，我会收到错误消息
java.lang.IllegalStateException:无法将光标移动到位置 2
同样，如果我有 n 个联系人，情况也是如此。
我见过this question但在那里找不到任何答案。请帮忙
这是日志

我找不到显示的错误行。这让我很困惑
最佳答案
感谢您的帮助。此问题与 getCount() 有关。我以前也这么做过，后来没注意到。
@Override
public int getCount() {
return names.size();
}
我删除了这个，它工作正常。感谢您的帮助
