推荐答案

使用<一个href="http://developer.android.com/reference/android/app/Activity.html#getCallingActivity%28%29">getCallingActivity()

注意：如果调用活动没有期待的结果（即它没有使用 startActivityForResult（意图，INT）的形式，包括：请求code），然后调用包将为null

Note: if the calling activity is not expecting a result (that is it did not use the startActivityForResult(Intent, int) form that includes a request code), then the calling package will be null
