Android :: Progress Dialog With A Second Thread
Sep 26, 2009I've created ProgressDialog with a second thread according to the DevGuide,changes screen orientation or 2) hits the back button twice (first to hide the dialog, second to hide the app) to hide the application and run the app again after a while.Then, onCreate() is called (for the second time), and progress bar stops responding properly. My thread may work for a few minutes and I want to give the user possibility to hide it and do sth else. After a while he might want to run the app again in order to check the progress.I found a few articles concerning this topic, but I couldn't find the exact solution I should chose for this problem. So, could you tell mi what is the proper way to handle this? Should i save the handler and dialog state with "onRetainNonConfigurationInstance()"? If so, how to do it properly and is it safe?

Apr 15, 2010i had made an application which download a huge list from the internet and display in a listview. The Listview class is supported by my own Class which is extension of the BaseAdapter base class. In the display list adapter getView method I use simple_list_item_multiple_choice. When I would like to insert an progress dialog with a Thread, the System is die with NullPointer Exception in the last row: *public View getView(int position, View convertView, ViewGroup parent) {if(convertView == null) convertView =inflater. inflate (android .R. layout.simpl e_list_item_multiple_choice, parent,false); try {ViewHolder vh = new ViewHolder(); vh.check TextView = (Checked TextView) convertView.findViewById(android.R.id.text1); vh. check TextView. setEnabled (true);* BUT if I don't use the Thread all going to right, there will no NullPointer Exception Can anyone tell me why ? Any solution?

Oct 17, 2010I have recently experimented with creating an easy way to open a ProgressDialog up in a second thread, so if the main thread freezes the dialog will keep working. Here is the class: public class ProgressDialogThread extends Thread
public Looper ThreadLooper;
public Handler mHandler;public ProgressDialog ThreadDialog;
public Context DialogContext;
public String DialogTitle;
public String DialogMessage;
public ProgressDialogThread(Context mContext, String mTitle, String mMessage)
{ DialogContext = mContext;
DialogTitle = mTitle;
DialogMessage = mMessage;
} public void run()
{ Looper.prepare();
ThreadLooper = Looper.myLooper();
ThreadDialog = new ProgressDialog(DialogContext);
ThreadDialog.setTitle(DialogTitle);
ThreadDialog.setMessage(DialogMessage);
ThreadDialog.show();
mHandler = new Handler();
Looper.loop();
} public void Update(final String mTitle, final String mMessage)
{ while(mHandler == null)
synchronized(this) {
try { wait(10); }
catch (InterruptedException e) {
Log.d("Exception(ProgressDialogThread.Update)", e.getMessage() == null ? "MISSING MESSAGE" : e.getMessage());
mHandler.post(new Runnable(){
@Override
public void run() {
ThreadDialog.setTitle(mTitle);
ThreadDialog.setMessage(mMessage);
public void Dismiss()
{ while(ThreadDialog == null || mHandler == null)
synchronized(this) {
try { wait(10); }
catch (InterruptedException e) {
Log.d("Exception(ProgressDialogThread.Dismiss)", e.getMessage() == null ? "MISSING MESSAGE" : e.getMessage());
mHandler.post(new Runnable(){
@Override
public void run() {
ThreadDialog.dismiss();
public void Continue()
{ while(ThreadLooper == null || mHandler == null)
synchronized(this) {
try { wait(10); }
catch (InterruptedException e) {
Log.d("Exception(ProgressDialogThread.Continue)", e.getMessage() == null ? "MISSING MESSAGE" : e.getMessage());
mHandler.post(new Runnable(){
@Override
public void run() {
ThreadLooper.quit();
However it sometimes work perfectly but other times the application simply freezes and crashes eventually.Here is an example of use:ProgressDialogThread thread = new ProgressDialogThread(this, "Loading", "Please wait...");
thread.start();
// Do Stuff
thread.Dismiss();
thread.Continue();It generates a lot of warning and even some crashes sometimes: eg. Handler: Sending message to dead thread.and exceptions like ANR
Android :: Progress Dialog Working In Thread
Jul 27, 2010Trouble is, that ProgressDialog show only after loading run(), but I need to show it on start and showing it while loading some data. I put: "dialog = ProgressDialog.show(CategoriesListActivity.this,"Working...","Loading data", true);" in method run(), but the same. I print in Log.i() some info (int i++) and put title of ProgressDialog. Method work correctly, but don't show ProgressDialog. I have read some info that some thread block another thread (my created), that's why doesn't show progressDialog, but can't do anything.

Android :: Progress Dialog Thread Stops When Closing G1

View 6 Replies View RelatedAndroid :: Displaying Progress Dialog From Open GL Thread
May 9, 2010Does anyone have expirience with opengl-ui-opengl threading interraction? I'am developing a small opengl application. I'am a little bit confused with separate opengl thread. Currently, my application is logically separated in two parts - the controlling one and the rendering one. The controlling part interracts with user - accepting user input, changing activities, dealing with files and so on. The rendering part - just render everything it should. Ok, so when I need to load new texture to opengl (unfortunatelly its large and I cant reduce its size), I'd like to show a ProgerssDialog dialog. Trying to show it from the open gl thread brings me an exception: "Can't create handler inside thread that has not called Looper.prepare()". Because the initiator of loading is in the ui thread (for example - user selected a menu option), I'am opening the dialog, adding the load Runnable to stack on Runnables that will be called in Render.onDrawFrame and passing there a callback that will be executed after texture is loaded.

Android :: Update Text When Dialog Open And Dismissed In Thread
Aug 18, 2010Look at my code.
- code -
private Handler handler = new Handler(); private ProgressDialog dialog;
final Runnable runInUIThread = new Runnable() { public void run() { dialog.dismiss();
} };
private void DoThis() {
dialog = new ProgressDialog(Main.this); dialog.setTitle("Title");
dialog.setMessage("Text"); dialog.show();
Thread newTask = new Thread() {
@Override public void run() { Looper.prepare(); DoThat();
handler.post(runInUIThread); Looper.loop();
); newTask.start(); } }
Is it possible to use test.setText("something") in this thread to update a Button text or TextView in the LinearLayout after the dialog is dismissed? I try cheating placing:
test.setVisibility(View.INVISIBLE);
test.setText("something");
test.setVisibility(View.VISIBLE);
after dialog.show();
It kind of updated the text when the dialog open. I want to do it after the dialog was dismissed. What is the correct way to implement this in my thread?

Android :: Find Table Leyout In Thread (Because Of Progress Dialog)
Jun 5, 2010On my activity, im getting some big data from web, and while getting this data i want to show the user a ProgressDialog with spinning wheel.

Android :: Dialog Activity To Return Before Continuing Executing Of Main Thread
May 22, 2010How would I force the current thread to wait until another has finished before continuing. In my program the user selects a MODE from an AlertDialog, I want to halt executing of the program before continuing as the mode holds important configuration for the gameplay.

.setItems(R.array.game_modes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case 0:
setMode(TRAINING_MODE);
case 1:
setMode(QUIZ_MODE);

setMode(TRAINING_MODE);
break; ............
//continue loading the rest of onCreate();
contineOnCreate(); } })
.create().show();
If this is impossible can anyone give a possible solution?
Android :: ASync Task Progress Dialog Not Showing Until Background Thread Finishes
Apr 24, 2010I've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?

Jul 10, 2009My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler.This all works fine, except when screen orientation changes while the dialog is up (and the background thread is going). At this point the app either crashes, or deadlocks, or gets into a weird stage where the app does not work at all until all the threads have been killed.How can I handle the screen orientation change gracefully?

View 4 Replies View RelatedAndroid :: Find GPS Location Once / Show Loading Dialog
Aug 15, 2010I am writing an app that requires the user's current location (lastknownlocation won't be very helpful) and displays a list of all the closest "items" to them taken from the database.I have got the finding of the closest items working well but only using a hardcoded latitude and longitude location for the time being but now it is time to implement finding the actual location.Can anyone provide an example of how to have the app find the current fine location in the background and have the app wait. I only need the location once not updates as the person moves. I have implemented a location listener however I understand getting a GPS fix can be slow. I have seen other examples using last known location or implementing the location listener which continues to run and update however as my Activity needs the location coordinates before it can display anything the app just crashes. I need to show a Progress Dialog while its searching.
How can I have the locationlistener run once in the background and then remove location updates once it finds the location. I need the rest of the application to wait until it has a GPS location or timeout after say 20-30seconds. I would like a ProgressDialog up so the user knows that something is going on, but it just has to be the spinning loading animation not a percentage or anything. If possible I would like the user to be able to cancel the dialog if they are sick of waiting which then they can search by typing suburb etc instead.I have been trying to do it with threads but it is getting way more complicated than I feel it should be and still not working anyway. On iPhone this is much more simple?Can anyone provide a nice way of doing this, I have been ripping my hair out for a week on this and it is really putting me behind schedule for the rest of the app completion date.
