먼저 사용자의 현재 위치를 가져 오는 중입니다. MapActivity입니다. 현재 위치를 얻으려면 AsyncTask 개념을 사용했습니다. 이제 달성하기 위해 무엇을 ProgressDialog 현재 위치를 얻을 때까지 사용자에게 표시하는 것입니다.

좋습니다. 그것의 일 벌금. getApplicationContext()를 사용할 때 왜 에러가 발생하는지 말해 주시겠습니까 ?? – Scorpion
대화 상자는 전체 응용 프로그램이 아닌이 특정 활동과 관련이 있습니다. 일반적으로 범위가 활동 인 객체를 만들 때 Activity.this를 사용하십시오. 현재 활동 범위를 벗어나는 범위의 개체를 만들 때 응용 프로그램 컨텍스트를 사용하십시오. –
흠. 정보를 제공해 주셔서 감사합니다. 나는이 개념을 알고 있었지만 이것을 생각하지 않았습니다. 다시 한번 감사드립니다 ... – Scorpion
