android - ProgressDialog doesn't appear when calling a thread inside AsyncTask -


I have an app that sends a file through a socket, while doing so I want to show progress in the progression. The app sends the file completely, but I am not able to display the dialog. 

  increases public activity ProgressDialogActivity {Private ProgressDialog downloadDialog = null; Private string filePath; @ Override Protected Zero (InstanceStat saved from bundle) {// Todo auto-generated method stub super. Connet (Saved Instantstate); FilePath = getIntent (). GetExtras () GetString ("file path"); DownloadingOug = new progression (this); Work myTask = new work (); MyTask.execute (0); } Private Zero Show Message (Last String msg) {this.runOnUiThread (New Runnabal) {@Override Public Zero Run () {// TODO Auto generated method Stub Toast. Make text (getApplicationContext (), msg, 'enter code' toast.LENGTH_SHORT) .show ();}}); } Working in the Private Class Async Task & lt; Integer, integer, boolean & gt; Observer {Private thread t; Applies; @ OverEride Protected Zero on PreExecute () {// TODO Auto generated method stub super.onPreExecute (); DownloadDialog.setTitle ("send"); DownloadDialog.setMessage ("................"); DownloadDialog.setCancelable (wrong); DownloadDialog.setIndeterminate (wrong); // downloadDialog.setMax (100); DownloadDialog.setProgressStyle (ProgressDialog.STYLE_HORIZONTAL); DownloadDialog.show (); } @ Override protected boolean do inbackground (integer ... parameter) {SendFile Send = New SendFile (filePath); DownloadDialog.setMax (0); T = new thread (send); Send.registerObserver (this); // try {// thread Sleep (10000); // Grip (Interrupted E) ect // // TODO auto generated generated blocks // e.printStackTrace (); //} Start (); Back true; } @ Override Protected Zero Progress Update (Integer ... Value) {// TODO Auto generated method stub super.onProgressUpdate (value); Int counter = value [0] .intValue (); DownloadDialog.setProgress (counter); If (filePath! = Null) {downloadDialog.setMessage (filePath + "..."); }} @ Override Public Old Update (subject theme) {// Tudo Auto-Generated Math Stub If (Theme theme of SendFile) {SendFile e = (SendFile) topic; If (efexception ()! = Null) {t.interrupt (); ShowMessage (e.getException ()); } Else {if (! E.isStarted ()) {initializeProgressBar (e.getNumIter ()); } Else {refreshProgressBar (e.getNumIter ()); } If (E.Esent ()) {t.interrupt (); Show Message ("File Sent"); }}}} Public Zero initializeProgressBar (int max) {downloadDialog.setMax (max); } Public Zero Refresh Progressbar (Int.) {Published Progress (downloadDialog.getMax () - Zodiac); } @ Override postx (Boolean results) protected zeros {// Todo auto-generated method stub super.PostXAquate (results); If (downloadDialog! = Null) {downloadDialog.dismiss (); } End(); } @ Override protected void was canceled () {// Todo auto generated method stub super.onCancelled (); t.interrupt (); Show Message ("Task Cancel"); }}; }   
 Send file is a class that contains a socket to send the file.  
 I think the problem is that I am calling the thread inside the Asynca Task because when I am making the thread sleep (10000), for that time I can see progression DL, but I do not know how to fix it.  
 In addition, when I run a debugger, I can see that the variable 'counter' is called every time I call it, but if I  'DownloadDialog.getProgress ()' , then  always 0  is there.   
 
 
 You are creating an asyncTask, which infuses the INFafground () method in the background. In there, you do not do anything, but start a new thread ... now this thread works, but your Asinca task ends, because after starting another thread, there is nothing to do with it. So, your progress has been shown for some milliseconds, then your ASINNA Task ends and progress progresses again from the DLOgh.  
 Solution: Use either an asyncTask or use a thread.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
