使用整数，字符串的其他活动等 [英] Using Integers, Strings etc in other Activities

问题描述

我有两个活动。在一个我计算了一些东西，所以我有一些整数，也有一些字符串存储。所以，现在我想在我的第二个活动中使用这些蜇伤和整数。如何在我在第二次活动使用它们？

I've got two Activities. In one I calculate some things and therefore I have some Integers and also some Strings stored. So now I would like to use these Stings and Integers in my second Activity. How an I use them in my second Activity?

推荐答案

您得把它们传递给你的第二个活动。

You gotta pass them to your second activity.

当您创建意图开始活动

Intent i = new Intent(FirstActivity.this, SecondActivity.class);

做额外的步骤是这样

do extra step like this

i.putExtra("integer", myInteger); //where myInteger is integer you have in first Activity
i.putExtra("string", myString); //where myString is String you have in first Activity

startActivity(i);

和现在的第二个活动来访问这些值使用以下code

and now in second Activity to access those values use following code

int in = this.getIntent().getExtras().getInt("integer");
String str = this.getIntent().getExtras().getString("string");

就这么简单。
