請幫助我，我創建了一個類newReclamation，我們可以在其中添加回收名稱，類型，描述和位置MapView。我如何添加MapView並用Marker手動標記我的位置，然後在mysql數據庫中保存（Lang，Lat）。 PS：現在我只保存回收名稱，類型和描述，它的工作原理。請幫幫我。將地圖添加到我的活動

我想使用谷歌地圖添加位置。請有任何想法嗎？
我們不能幫助您，直到您與我們分享您的代碼 –
我編輯了我的出版物，您現在可以找到我的代碼。我想添加谷歌地圖的位置，並將其保存在數據庫中 – salma
您應該從這裏開始：https：//developers.google.com/maps/documentation/android-api/start，因爲您必須先實施谷歌地圖，然後才能獲得來自用戶的位置。 –
