传递一个int值到另一个类 [英] Passing a Int value to another class

问题描述

我有四组在ListView每个单元有四个网址我想在一个web视图加载。当用户选择一个链接直接转到我设置的值，像这样;

I have four groups in a listview each with four url's I want to load in a webView. When the user select a url to goto I set a value like so;

 if (position == 0) webb = webb +2;
 {
       Intent intent = new Intent(this, official.class);
       startActivity(intent);
 }

我再结转库存的意图转移到web视图类，我已经给每个URL值像这样;

I then carryout the intent to move to the webView class where I have given each url a value like so;

if (webb == 2) mWebView.loadUrl("http://yahoo.com");
if (webb == 3) mWebView.loadUrl("http://www.bbc.co.uk");

但屏幕保持空白，如果我说出它的工作原理official.class内的值。

But the screen stays blank, if I state the value inside the official.class it works.

我怎样才能得到这个值基础上，用户从列表视图中选择传递给另一个类。很抱歉，如果这是很难理解的。

How can I get this value to pass to another class based on the selection the user makes from the listview. Sorry if this is hard to understand.

推荐答案

如果你的问题是如何共享活动之间的数据（如您的韦伯值），那么你可能想看看<一href="http://developer.android.com/reference/android/content/Intent.html#putExtra%28java.lang.String,%20android.os.Bundle%29"相对=nofollow> Intent.putExtra（...）方法。更多信息：

If your question is how to share data between activities (such as your webb value), then you might want to look at the Intent.putExtra(...) methods. More info:
