推荐答案

您可以将指针从活动范围内传递到活动相关服务并启动另一个活动在那里。

You can pass the pointer to activity to a service and start another activity out there from the activity context.

在从中您将收到的结果使这样的一个活动：

In an activity from which you will receive the result make something like this:

private static Activity activity;
public static Activity getActivity() {
    return activity;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    activity = this;
}

实现的onActivityResult那里，做的方式向结果传递给无论是LocalBroadcastManager或静态字段，或粘合剂服务 - 无论适合你。

Implement onActivityResult out there and make a way to pass the result to a service either by LocalBroadcastManager or static fields, or Binder - whatever suits you.

这时从服务呼叫

TheActivity.getActivity().startActivityForResult(...
