안드로이드 1to50 게임을 만들어봤습니다.

공감 및 댓글은 포스팅 하는데  아주아주 큰 힘이 됩니다!! 포스팅 내용이 찾아주신 분들께  도움이 되길 바라며 더 깔끔하고 좋은 포스팅을  만들어 나가겠습니다^^

안드로이드 1to50 게임을 만들어봤습니다.

RxJava를 사용해서 타이머를 구현해봤습니다.

5 x 5 판은 RecyclerView에 GridLayoutManager를 set 해서 만들었고,

터치 이벤트는 item들의 좌표를 구해서 좌표에 해당하는 position이

선택되도록 만들었습니다.

데이터바인딩도 사용했습니다.

사이즈는 대충 만들었기 때문에 사용하실 분들은 본인 스크린사이즈에 맞게

사용하셔야 합니다.
