android - Android 中的跨区格式和 html 格式

标签 android

我需要在 android 应用程序的 html 输出中格式化这个字符串:

<a href=http://www.mywebpage.net?ID=764>My remote pics</a>

并在 ListView 中尝试了 Spanned 方法:

Spanned varHtml = Html.fromHtml(var.toString());

ArrayList<String> planetList = new ArrayList<String>();
planetList.addAll(Arrays.asList(varHtml));

listAdapter = new ArrayAdapter<String>(this, R.layout.simplerow,
        R.id.rowTextView, planetList);
listAdapter.addAll(varHtml.toString());
mainListView.setAdapter(listAdapter);

但是我在这一行中有这个错误，为什么？

listAdapter.addAll(varHtml.toString());

错误

The method addAll(Collection<? extends String>) in the
type ArrayList<String> is not applicable for the
arguments (List<Spanned>)

最佳答案

addAll想要一个 Collection要添加的项目。

你应该使用 add在这种情况下采用 String 的方法。

Appends the specified element to the end of this list.

改变

listAdapter.addAll(varHtml.toString());

到

listAdapter.add(varHtml.toString());

这就是你应该做的事

String html = "<a href=http://www.mywebpage.net?ID=764>My remote pics</a>"; // the HTML to read
Spanned spanned = Html.fromHtml(html);

Object[] strings = spanned.getSpans(0, html.length(), Object.class);

List<String> urls = new ArrayList<String>();
for (Object obj : strings)
{
    if (obj instanceof URLSpan)
    {
        URLSpan urlSpan = (URLSpan) obj;

        urls.add(urlSpan.getURL());
    }
}

它将读取每个 Url 并将所有内容添加到 urls 列表中。您可以直接更新您的列表或做

listAdapter.addAll(urls);

这就是你能做到的；

public class news extends Activity {

    private static final String SOAP_ACTION = "http://www.xxxxx.com/WebService/GetNews";
    private static final String OPERATION_NAME = "GetNews";
    private static final String WSDL_TARGET_NAMESPACE = "http://www.xxxxx.com/GetNews";

                SoapEnvelope.VER11);

        envelope.dotNet = true;
        envelope.implicitTypes = false;
        envelope.setOutputSoapObject(request);

        HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);

            // it's not needed
            RemoteString = RemoteString.replaceAll("<br />", "\n");
            Log.i("RemoteStringnew", RemoteString);

            //Split in remote string

            for (String html : var)
            {
                Spanned varHtml = Html.fromHtml(html);

                Object[] strings = varHtml.getSpans(0, html.length(), Object.class);

                List<String> urls = new ArrayList<String>();
                for (Object obj : strings)
                {

                    {
