Я считаю, что в Jsoup нет методов для получения прогресса get () и post (). Мне удалось сделать это через HttpURLConnection, а затем передать Jsoup.parse файл. Это выглядит так:
(не забудьте добавить разрешения в файл манифеста)
WithFileProgress.java:
public class WithFileProgress {
ProgressDialog progressDialog;
Context context;
TextView content;
public WithFileProgress(Context context, TextView content) {
this.context = context;
this.content = content;
}
public void connect(String url) {
new downloadHTML().execute(url);
}
private class downloadHTML extends AsyncTask<String, Integer, Document> { // params, progress, result
@Override
protected void onPreExecute() {
super.onPreExecute();
progressDialog = new ProgressDialog(context);
progressDialog.setTitle("downloadHTML");
progressDialog.setMessage("Loading...");
progressDialog.setIndeterminate(true);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setCancelable(true);
progressDialog.show();
}
@Override
protected Document doInBackground(String... params) {
InputStream input = null;
OutputStream output = null;
HttpURLConnection connection = null;
File file;
Document d = null;
try {
URL url = new URL(params[0]);
connection = (HttpURLConnection) url.openConnection();
connection.connect();
// expect HTTP 200 OK, so we don't mistakenly save error report
// instead of the file
if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("downloadHTML").setMessage("Server returned HTTP " + connection.getResponseCode()
+ " " + connection.getResponseMessage()).create();
}
// this will be useful to display download percentage
// might be -1: server did not report the length
int fileLength = connection.getContentLength();
// download the file
input = connection.getInputStream();
file = new File(Environment.getExternalStorageDirectory(), "downloadHTML.tmp");
output = new FileOutputStream(file);
byte data[] = new byte[8192];
long total = 0;
int count;
while ((count = input.read(data)) != -1) {
// allow canceling with back button
if (isCancelled()) {
input.close();
return null;
}
total += count;
// publishing the progress....
if (fileLength > 0) // only if total length is known
publishProgress((int) (total * 100 / fileLength));
output.write(data, 0, count);
}
d = Jsoup.parse(file, null);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (output != null)
output.close();
if (input != null)
input.close();
} catch (IOException ignored) {
}
if (connection != null)
connection.disconnect();
}
return d;
}
@Override
protected void onPostExecute(Document d) {
super.onPostExecute(d);
content.setText(d.html());
progressDialog.dismiss();
}
@Override
protected void onProgressUpdate(Integer... values) {
super.onProgressUpdate(values);
// if we get here, length is known, now set indeterminate to false
progressDialog.setIndeterminate(false);
progressDialog.setMax(100);
progressDialog.setProgress(values[0]);
}
}
}
