我正在为我的校报创建一个应用程序，但在尝试显示全文时遇到了问题。目前我有一个从 RSS 提要中提取的文章列表，当单击它时，它会显示文章的内容。然而，只有第一段显示在 TextView 中，无论它有多长。这让我也相信它与<p></p>HTML 标签有关。我对 RSS 提要或解析 XML 不是很熟悉（这是我第一次尝试），并且一直在寻找方法来完成我想要完成的工作。
我的这个项目基于这个博客的一系列帖子：http ://android-er.blogspot.com/2010/04/simple-rss-reader-in-listview.html
我采用了此处提供的项目并将其添加到带有滑动模板的选项卡中，并更改了某些元素的布局方式。
免责声明：有很多评论丑陋的代码，我懒得拿出来。这主要是我在布局中不想要的东西。这是包含文章列表的片段：

这是单击列表中的项目时启动的活动：
package com.nick.pocketslate;
import android.app.Activity;
import android.os.Bundle;
import android.text.Html;
import android.text.method.ScrollingMovementMethod;
import android.widget.TextView;
public class ShowDetails extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.details);
TextView detailsTitle = (TextView)findViewById(R.id.detailstitle);
TextView detailsPubdate = (TextView)findViewById(R.id.detailspubdate);
TextView detailsLink = (TextView)findViewById(R.id.detailslink);
TextView detailsContent = (TextView)findViewById(R.id.detailscontent);
Intent intent = getIntent();
detailsTitle.setText(intent.getStringExtra("keyTitle"));
detailsPubdate.setText(intent.getStringExtra("keyPubdate"));
detailsLink.setText(intent.getStringExtra("keyLink"));
detailsContent.setText(Html.fromHtml(intent.getStringExtra("keyContent")));
detailsContent.setMovementMethod(new ScrollingMovementMethod());
}
}
在这一点上，我已经做了很多搜索并没有找到解决方案，我不确定我的代码的哪一部分可能会导致问题。如果有人可以查看并找到问题，我有一个链接可以在此处下载我的完整项目。
如果有人知道从哪里开始寻找，我会提出那部分代码。
