我认为你应该使用的方法是：
public void startActivityForResult (Intent intent, int requestCode)
您可以在此处阅读更多信息：将该数据添加到意图本身如何？那也不行吗 比如：
i.putExtra("name","John");
Intent intent = getIntent();
String myName = intent.getStringExtra("name");
忘记finish（），认为我在上面单独编写的代码与该代码组合没有获得值假设您希望在登录活动中调用onActivityResult，在类活动中调用public final void setResult（int resultCode，Intent data）方法，然后调用finish（）。否则，您不会将结果传回登录活动的任何位置。您尝试发送的数据类型是什么？实际上，我想在OnActivityResult下发送combine变量中的combine值，问题是新活动正在打开，但数据未发送声明的
combinei.putExtra("name","John");
Intent intent = getIntent();
String myName = intent.getStringExtra("name");
