答案 0 :(得分：0)
我认为你应该使用的方法是：
public void startActivityForResult (Intent intent, int requestCode)
此外，在开始下一个活动后，您不必在原始活动上调用finish（）。
您可以在此处详细了解：http://developer.android.com/training/basics/intents/result.html
答案 1 :(得分：0)
如何将数据添加到意图本身？这不起作用吗？
类似的东西：
i.putExtra("name","John");
修改
在第二个活动中，您将获得如下数据：
Intent intent = getIntent();
String myName = intent.getStringExtra("name");
