私は2つの活動をしています。アクティビティsaveDataとアクティビティandroidCamera
まず、saveDataにフォームがあります。EditText「写真のアップロード」以外のフォームがすでに入力されている場合。次に、ボタンカメラをクリックしてURI/パス画像を撮影します。finish()
カメラアクティビティが値uri/pathをSaveDataフォームActivityに送り返すとき。問題は、SaveDataのEditText "Upload Photo"を更新する方法です。写真を撮ると、カメラはEditText "UploadPhoto"内のパス/uriを送信しますか?
これは私のアクティビティAndroidCameraです
