Google Maps Android API를 안드로이드에서 사용하는 방법과 GoogleApiClient를 이용하여 현재 위치를 구글맵에 표시하는 내용을 다음 포스팅에서 다루었습니다. 이번에는 Places API Web Service를 이용하여 현재 위치 주변의 음식점 정보를 구글맵에 표시하는 내용을 다룹니다.
[Android/Google Map] - Google Maps Android API v2 예제
[Android/Google Map] - GoogleApiClient를 사용하여 Android Google Map에 현재 위치 표시하기
Places API Web Service 키 얻기
Google Map에 현재 위치 주변의 음식점 표시하기
실행 결과
Places API Web Service 키 얻기
Google Developers Console(https://console.developers.google.com/project )에 방문합니다.
1. 프로젝트 만들기를 선택합니다.
2. 프로젝트 이름을 적어주고 만들기를 선택합니다.
3. 검색창에 place를 입력하여 검색되는 Google Places API Web Services를 선택합니다.
4. 사용 설정을 선택하면 잠시후 사용중지로 변합니다. 이제 Google Places API Web Services가 활성화 되었습니다.
5. 사용자 인증 정보 만들기를 선택합니다.
6. 어떤 사용자 인증 정보가 필요한가요?를 선택합니다.
7. API키가 생성되었습니다. 메모장에 복사해두고 완료를 선택합니다.
Google Map에 현재 위치 주변의 음식점 표시하기
Places API Web Service에서 제공하는 REST API를 이용하여 현재 위치 주변의 음식점에 대한 정보를 요청하여 획득된 JSON을 파싱하는 작업을 해주면 되지만 여기에서는 간단하게 구현이 가능한 Android-Google-Places-API를 사용했습니다.
Android-Google-Places-API( https://github.com/nomanr/Android-Google-Places-API )
다음 포스팅에서 작성했던 코드를 수정해서 진행했습니다.

activity_main.xml에 버튼을 추가하고 android:layout_weight 속성을 추가합니다.

실행 결과
실행하면 현재 위치가 지도에 표시되고 있습니다.
장소 검색 버튼을 누르면 현재 위치 주변의 음식점 위치들이 지도에 표시됩니다.
음식점 위치를 표시하는 마커 하나를 선택하면 음식점 이름과 주소가 나타납니다.
장소 검색버튼을 다시 누르면 기존 마커들을 다지우고 새로 음식점 마커들을 표시합니다.
