저는 아직 로그 캣을 보는 데 익숙해 져 있습니다. Android 개발을 배우기 위해 내 연락처에 연락처 앱을 만들고 있는데이 연락처 정보를로드하려고하면 오류가 발생합니다. 할 수 있으면이 logcat을 설명해 주시면 읽어주는 방법을 더 잘 이해할 수있는 좋은 기회가됩니다.

Answer 1

오류는 다음과 같습니다 no such column: contact_id1

이 줄에 =을 잊어 버렸기 때문입니다.

ContactsContract.Data.CONTACT_ID + contactId 

이는 contact_id = 1 대신에 contact_id1이됩니다. 그것은이어야한다 :

ContactsContract.Data.CONTACT_ID + " = " + contactId
