我正在尝试获取用户选择的联系人号码。问题是，无论何时从列表中选择联系人，都会抛出此异常：
android.database.CursorIndexOutOfBoundsException：请求索引0，大小为0
任何联系人都会发生这种情况，即使是那些有多个电话号码的联系人。
为我打开联系人列表的唯一示例：
Pick a Number and Name From Contacts List in android app
How to read contacts on Android 2.0
Android contacts database giving me an exception
他们都为我产生了同样的错误。
我的代码：
调用意图
public void pickPerson(View V)
{
Intent intent = new Intent(Intent.ACTION_PICK,
ContactsContract.Contacts.CONTENT_URI);
intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
startActivityForResult(intent, PICK_CONTACT);
}
获取电话号码
//Declcared earlier
static final int PICK_CONTACT=1;
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data)
{
super.onActivityResult(reqCode, resultCode, data);
switch (reqCode)
{
case (PICK_CONTACT) :
{
if (resultCode == Activity.RESULT_OK)
{
Uri contactData = data.getData();
Cursor c = getContentResolver().query(contactData, null, null, null, null);
if (c.moveToFirst())
{
String id =c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
String hasPhone =c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (hasPhone.equalsIgnoreCase("1"))
{
Cursor phones = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,
null, null);
phones.moveToFirst();
String cNumber = phones.getString(phones.getColumnIndex(PhoneLookup.NUMBER));
phone.setText(cNumber); //EditText view
}
}
}
break;
}
}
}

答案 0 :(得分：0)
你可以尝试这个String cNumber = phones.getString(phones.getColumnIndex("data1"));
