저는 Android가 처음이며 Android 앱에서 작업하고 있습니다. 이 앱에는 활동 편집과지도 활동이라는 두 가지 활동이 있습니다.두 액티비티간에 카메라 이미지로 인 텐트를 처리하고 Google Maps API에서 해당 이미지를 마커에 전달하면 작동하지 않습니다.
편집 활동에서 사용자는 데이터를 입력하고 잘 작동하는 Android 전화에서 사진을 찍을 수 있습니다. 다른 활동은 맵 활동이며지도의 마커가 표시됩니다.
지도의 아이콘에는 잘 작동하는 비트 맵이 포함되어 있습니다. 작동하지 않는 부분은 비트 맵 그래픽 대신 마커에 카메라 그림을 배치하는 부분입니다.
카메라의 이미지가 작동하는 편집 활동에 대한 이미지보기로 표시됩니다.
작동하지 않는 부분은 카메라의 의도를 다른 활동으로 전달하고 의도 내용을 마커에 배치하는 것입니다.
Here's 편집 활동 (많은 코드가 주석) :

안드로이드에, 나는이 문제에 더 오래 머물러있다. 도움이나 힌트를 주시면 감사하겠습니다.
안녕하세요 @rajendra, 노력해 주셔서 감사합니다. 그러나 코드는 여전히 동일한 결과를 생성하므로 원하는대로 작동하지 않습니다. Bitmap bmp = BitmapFactory.decodeResource (getResources(), R.drawable.icon) 카메라 이미지로 대체되어야하며 작동하지 않습니다. 더 이상의 도움이나 힌트를 주시면 감사하겠습니다! – user8623502
안녕하세요, 비트 맵을 디코딩하지 말고 편집 활동에서 의도를 보내려면 가져와야합니다. 의도 intent = getIntent(); bmp = (비트 맵) intent.getParcelableExtra ("BitmapImage"); – rajendra
intent.putExtra ("BitmapImage", photo); \t \t \t // 비트 맵을 다음 활동으로 전달합니다. 다음 활동으로 되 찾으십시오. – rajendra
