我想在Android ListView项中添加可点击链接。每行ListView有5个项目,我只想让其中两个项目可点击,并使用putextras()意图在WebView中打开。我正在使用自定义适配器,请帮忙。
假设"链接1"是:"查看校对"(proofinglink)(在TextView中)和"链接2"是:"获取更多详细信息"(sitelink),我希望当我点击链接1时,它应该在WebView中打开其自己给定的URL。当我点击链接2时:它也应该在WebView中打开其自己给定的URL,使用putextras()意图。这是我的代码。

我希望“proofinglink”和“sitelink”可点击并在Web视图中打开
这是自定义适配器
