公共无效parseDoc（）{
新主题（新的Runnable接口（）{ @覆盖
公共无效的run（）{
字符串摘要=＆LT; HTML＆GT;＆LT;车身＆gt;您打进＆LT; B＆GT; 192＆LT; / B＆GT;点＆LT; / BODY＆GT;＆LT; / HTML＆gt;中;
sting.loadData（总结，text / html的，NULL）;
的HttpParams PARAMS =新BasicHttpParams（）;
HttpClientParams.setRedirecting（参数，可以真正的）;
HttpClient的=新DefaultHttpClient（）; httppost =新HttpPost（
https://secure.groupfusion.net/processlogin.php）;
串的HTML =;
尝试{

元件连结= doc.select（A）的第一（）;
linkHref = link.attr（HREF）; HTTPGET请求=新HTTPGET（）;
尝试{
request.setURI（新的URI（linkHref））; }赶上（的URISyntaxException E）{
// TODO自动生成catch块
e.printStackTrace（）;
}
响应= httpclient.execute（请求）; 。InputStream的时间= response.getEntity（）的getContent（）;
读者的BufferedReader =新的BufferedReader（
新的InputStreamReader（中））;

而（（行= reader.readLine（））！= NULL）{
str.append（线）;
}
附寄（）;
的HTML = str.toString（）;
sting.loadData（HTML，text / html的，NULL）; }赶上（ClientProtocolException E）{

解决方案
尝试使用下面的方法来加载web视图
mWebView.loadDataWithBaseURL（NULL，htmlString，text / html的，UTF-8，NULL）;
I am retrieving the whole html and javascript of a page I get from an HttpGet. I can successfully get the Html and the Javascript. When I try and load it into the web view, the web view gives me "Page not available" and shows the html and javascript that was to be loaded in a really weird format with percentages in between the elements. I am positive the html and javascript is being downloaded and in the shape of an Html page. I have also enabled javascript in the web view. What could be causing such a problem? Code:
public void parseDoc() {
new Thread(new Runnable() {
@Override
public void run() {
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
sting.loadData(summary, "text/html", null);
HttpParams params = new BasicHttpParams();
HttpClientParams.setRedirecting(params, true);
httpclient = new DefaultHttpClient();
httppost = new HttpPost(
"https://secure.groupfusion.net/processlogin.php");
String HTML = "";
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
3);
nameValuePairs
.add(new BasicNameValuePair(
"referral_page",
"/modules/gradebook/ui/gradebook.phtml?type=student_view&jli=t&jli=t&jli=t&jli=t&jli=t&jli=t&printable=FALSE&portrait_or_landscape=portrait"));
nameValuePairs.add(new BasicNameValuePair("currDomain",
"beardenhs.knoxschools.org"));
nameValuePairs
.add(new BasicNameValuePair("username", user));
nameValuePairs
.add(new BasicNameValuePair("password", pass));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HTML = EntityUtils.toString(response.getEntity());
Document doc = Jsoup.parse(HTML);
Element link = doc.select("a").first();
linkHref = link.attr("href");
HttpGet request = new HttpGet();
try {
request.setURI(new URI(linkHref));
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
response = httpclient.execute(request);
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
str.append(line);
}
in.close();
HTML = str.toString();
sting.loadData(HTML, "text/html", null);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
}
}).start();
}
解决方案
