연락처 및 전화 번호에서 전자 메일을 가져 오는 방법 연락처 및 클래스에서 확장 활동 및 oncreate() 메서드가 있습니까?

Question

나는 전화 번호를 얻고있다. 활동을 연장 한 연락처와 oncreate 방법으로 메일을 보낸다. fallowing 코드를 사용하여

:

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ 
      Class A extends Activity{ 

    new ClassB(this); 
}

그것은 결과를 얻기에서 잘 작동하지만 위의 예에서 fallowing 코드를 구현하는 방법을 모르는

:

ApplicationConstants.phoneContacts 
.add(new ContactNumberBean(nameOfContact, 
contactNumber, contactNumberType)); 

있는 경우를 하나는 나를 도와주세요.

Answer 1

ContentResolver에 액세스하여 ContentProviders를 쿼리하기 위해서만 android.content.Context 객체에 액세스해야합니다. 활동은 컨텍스트를 확장하므로 작동합니다. android.app.Service는 Activity도 확장하므로 너무 유용합니다. android.app.Application 또한 Context를 확장하므로 너무 효과적입니다.
