我是新的android和我試圖從一個網站使用jsoup獲取數據，但是當我執行get（）方法沒有反應。這裏是我的代碼：無法連接到使用Jsoup的網站android
static final String BLOG_URL = "http://xjaphx.wordpress.com/";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_html_parser);
// Show the Up button in the action bar.
setupActionBar();
// process
new DownloadFilesTask().execute();
}
私有類DownloadFilesTask擴展的AsyncTask {
String result = "";
@Override
protected String doInBackground(Void... params) {
// get html document structure
Document document=null;
try {
document = Jsoup.connect(BLOG_URL).get();
// selector query
Elements nodeBlogStats = document.select("div#blog-stats ul li");
// check results
if(nodeBlogStats.size() > 0) {
// get value
result = nodeBlogStats.get(0).text();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// return
return null;
}
protected void onPostExecute()
{
TextView article = (TextView)findViewById(R.id.textView1);
article.setText(result);
}
}
這是我的logcat日誌：
