Java 尝试在使用AsyncTask读取RSS时更新UI，但无效

java android rss

Java 尝试在使用AsyncTask读取RSS时更新UI，但无效,java,android,android-asynctask,rss,rss-reader,Java,Android,Android Asynctask,Rss,Rss Reader,我的应用程序正在向名为rssItems的ArrayList读取RSS，我试图做的是在ArrayList中添加新项时调用适配器的setDataSetChanged方法。我还使用AsyncTask从不同的线程读取RSS 为此，我将AsyncTask作为一个参数传递到RssParseHandler中，这样，每当AsyncTask对象读取完RSS项时，该处理程序就可以调用publishProgress方法。由于publishProgress是一个受保护的方法，因此我编写了一个名为publishProgr

我的应用程序正在向名为

rssItems

的

ArrayList

读取RSS，我试图做的是在

ArrayList

中添加新项时调用适配器的

setDataSetChanged

方法。我还使用AsyncTask从不同的线程读取RSS

为此，我将

AsyncTask

作为一个参数传递到

RssParseHandler

中，这样，每当

AsyncTask

对象读取完RSS项时，该处理程序就可以调用

publishProgress

方法。由于

publishProgress

是一个受保护的方法，因此我编写了一个名为

publishProgress

的公共包装器方法，以便处理程序可以在

AsyncTask

对象之外调用它。下面是我的一些代码：

public class MainActivity extends Activity {

private MainActivity local;
private List<RssItem> rssItems;
RssItemAdapter<RssItem> adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    this.rssItems = new ArrayList<RssItem>();

    this.adapter = new RssItemAdapter<RssItem>(local,
            R.layout.rss_row_view, rssItems);

    // Get references to the Fragments
    FragmentManager fm = getFragmentManager();
    // find the fragment
    newsFragment newsFragment = (newsFragment) fm
            .findFragmentById(R.id.newsFragment);

    newsFragment.setListItems(rssItems);

    newsFragment.setListAdapter(adapter);


    GetRSSDataTask task = new GetRSSDataTask(this.rssItems, this.adapter, "blah.jpg");
    task.execute("http://somesite.net/category/news/feed/");

    Log.d("RssReader", Thread.currentThread().getName());
}

感谢您的帮助

将e.getMessage（）更改为e.toString（）后：

更改为e.printStackTrace（）后：

将rssItems添加到RssReader后：

我知道这是因为我试图在与UI线程不同的线程中更改UI。你知道怎么改吗

尝试将doInBackground的返回类型设置为Boolean（确保将所有“Void”更改为“Boolean”然后返回Boolean.TRUE表示成功，或返回Boolean.FALSE表示失败。我不确定这是否会修复错误，但最好从doInBackground返回一些内容。另外，请确保日志调用中没有记录空对象。

尝试此操作

使用

.printStackTrace（）；

查看错误消息

try { // Parse RSS, get items rssReader.getItems(); } catch (Exception e) { e.printStackTrace(); }
编辑：
将
this.rssItems=rssItems；
添加到
RssReader.class

public RssReader(String rssUrl, String icon, List<RssItem> rssItems, GetRSSDataTask task) { this.rssUrl = rssUrl; this.icon = icon; this.task = task; this.rssItems = rssItems; }

public RssReader（字符串rssUrl、字符串图标、列表rssItems、GetRSSDataTask任务）{ this.rssUrl=rssUrl； this.icon=图标； this.task=任务； this.rssItems=rssItems； }
请指出第49行@
GetRSSDataTask
@Shayanpourvatan第49行是“return null；”。返回null有什么问题吗？感谢您的帮助！第49行是什么？是登录catch吗？
46:catch（异常e）{47:log.e（“RssReader”，e.getMessage（））；48:}49:return null；
请更改
e.getMessage（）
到
e.toString（）；
和测试again@Lee7355512727检查我的编辑。只需放入
e.printStackTrace（）；
它就会显示错误。无需在日志中给出该错误。第44行是rssReader.getItems（）；@Lee7355512727
RssParseHandler.java中的行号51
51:this.rssItems.add（currentItem）；52:this.task.publicPublishProgress（）；非常感谢！现在我遇到了另一个错误。请检查我对问题的编辑。
