我從我想通過如姓名，地址我在OnpostExecute了另一個電子郵件活動字符串數據singlePlaceActivity類。我的singlePlace活動成功地啓動了電子郵件活動，但我沒有在使用getextra方法的電子郵件活動中收到putExtra string data，並且我通過logcat驗證了我的字符串數據名稱，地址和電話沒有空值。使用意向接收使用putExtra和getExtra方法次活動空數據
SinglePlaceActivity：

Heyy kaushik它不工作，我的字符串值的名稱，地址，電話不爲空我從logcat驗證。即使我沒有在第二個活動，即電子郵件活動geting沒什麼。 – user3930098 2014-09-06 06:27:49
「緯度」和「經度」如何？ – kId 2014-09-06 06:49:17
截至目前，我不需要經緯度。 – user3930098 2014-09-06 09:08:18
