我已经构建了以下方法来使用从 Contacts 表中获取的 id 从 RawContacts 表中获取 id。此方法因异常而失败。
public int getRawContactId(int contactId)
{
String[] projection=new String[]{ContactsContract.RawContacts._ID};
String selection=ContactsContract.RawContacts.CONTACT_ID+"=?";
String[] selectionArgs=new String[]{String.valueOf(contactId)};
Cursor c=context.getContentResolver().query(ContactsContract.RawContacts.CONTENT_URI,projection,selection,selectionArgs , null);
int rawContactId=c.getInt(c.getColumnIndex(ContactsContract.RawContacts._ID));
Log.d(TAG,"Contact Id: "+contactId+" Raw Contact Id: "+rawContactId);
return rawContactId;
}
对应的 Logcat 如下所示:
