I just tried to implement a progressdialog and I have some issues to change the text during my long and complex calculations.
CODE:..........
I can clearly see the incrementProgressBy working and my dialog updating, but the message does not change.
Any idea on how to make that work?

View 2 Replies View RelatedI have a listview of items (songs on the sd card). The user has an option to load all the songs on the sd card to into a current playlist -- those songs are what is displayed in the listview. Because this can take few seconds to load if they have a lot of songs on the card, I want to display a progress dialog to just tell the user "One moment..." until the list refresh is done.
I launch a thread to do this. I've done this successfully on another app I have (which just updates a database in the background but doesn't update any display), but this one fails with this error message, "Can't create handler inside thread that has not called Looper.prepare()". I chopped down the activity and pasted it below. What am I doing wrong here? I have just a vague idea of what might be happening.
By the way, everything works when I take out the threaded stuff, it just looks like the app freezes for a couple seconds.

In ProgressDialog's documentation it says:"A dialog showing a progress indicator and an optional text message or view. Only a text message or a view can be used at the same time."I've gotten it working beautifully with a message, but I want to use a custom view instead - a message with a cancel button. But calling setView() on the ProgressDialog seemingly has no effect - it shows the progress bar in the dialog but nothing else. I've tried it with just a TextView with the text "hello", but it doesn't show up.

To ascertain version: Go to Dialer/Hit Star/#9999#
You will see the PDA; Phone; and Software Version numbers in this section
The T939xxxx6 for PDA AND PHONE and then
Software Version - ending in .006 on the last line.
I was told that the reason that I keep seeing the "No update file exists" message when I check "update firmware" is because I have the latest version.
At some point my phone was updated without giving me a message. I did notice the red and blue arrows yesterday. But there was no message. My SD card mounted and dismounted on its own and gave an error message, and then all references to the error and SD card disappeared.
If your phone is/has exhibited this sort of behavior, you may already have the update.
I want to show an update message for a new release - the first time the user opens the updated version of my app, a pop-up dialog should appear, saying what's new, with an OK button. After the user has read it once, it shouldn't appear again.
Is there any inbuilt Android variable I can check to see whether the user has opened the app before?
Of course, I can define my own boolean in the app settings ("hasUserSeenUpdateMessage") to check each time the app runs - setting it to false initially, and then true when the user clicks OK.
I try to show a ProgressDialog at the beginning of my application from an Activity. I debug the application and in theory the dialog is created because it prints a line from onCreateDialog... method.
For more test, I try to show a toast with:
Toast.makeText(MyActivity.this, "test", Toast.LENGTH_LONG);
And nothing is showed.
If is useful, the application is a widget.
I'm starting a ProgressDialog using:
ProgressDialog.show(Example.this, " " , " Loading. Please wait ... ", true,true);
Then running a block of code to download and parse XML.
The problem I'm having is that this is all running under a onClick button method, and that the xml is downloaded and parsed before the dialog is shown.
I'm trying to create a ProgressDialog for an Android-App (just a simple one showing the user that stuff is happening, no buttons or anything) but I can't get it right. I've been through forums and tutorials as well as the Sample-Code that comes with the SDK, but to no avail.
This is what I got:
CODE:..........
I've also tried adding pd.show(); and messed around with the parameter in new ProgressDialog resulting in nothing at all (except errors that the chosen parameter won't work), meaning: the ProgressDialog won't ever show up. The app just keeps running as if I never added the dialog.
I have a context menu option that, when clicked, will load some information from the web and insert it into a database.So this is a lengthy process and I would like to display a progressdialog over the top of the context menu when this option is selected.I've got the progressdialog running now, but it won't show up.It's almost like the context menu is covering it.So is there a way that I could get the progressdialog to show up on top of the context menu and be visible to the user.

So, i was trying to show a ProgressDialog to the user. However, nothing in hell makes the dialog appear.
The lengthy method is called from onCreate. I already tried to put it in onStart, but same thing. I also tried to run it in the ui thread, same thing: no dialog appears, even if "isShowing" returns true.

I have some code in my program that processes some stuff, and takes a few seconds. So I thought logically I can place my dialog show at the beginning before processing begins, and cancel it at the end. What ACTUALLY seems to be happening is my dialog shows after the processing is done... Some demo code to show what I mean with a simple sleep:

What is wrong with this code:-
CODE..................
I'm writing an Activity which fetches some XML from the web via HTTP and then parses it into a DOM. It then pulls some required data from the DOM.
As you can imagine, this takes a few moments, so I put that code into it's own thread and then tried to set up a ProgressDialog to display while the user is waiting for that to complete.
The problem is that the ProgressDialog doesn't display at all. If I remove the call to dismiss() then it displays after the work is done and, obviously, just sits there...
Here is my code:..................
The constructor of the FighterVersesDownloader is where all the work in terms of HTTP and DOM is done.
Any ideas on what I'm missing? I've seen a few similar threads on this using AsyncTask, but I wanted to use good old fashioned Threads directly and the solutions suggested don't apply.
I can't seem to grasp why this is happening.
This code:...................
Throws the following exception:
CODE:...........
I'm calling this from the onCreate method.
What I want is just to have the AsyncTaskTask showing a progressbar an external class. To do this I am passing the context as you can see in the main class. But whatever I try I get NullPointerException.
Working code examples.
Using Android 2.2 by the way.
main:
CODE:............
Update:
I have a follow up question: Using the above code, is it possible to return a value from the onPostExecute method back to the main class, somehow? (Sorry about beeing noobish)
I have tried something like this:
String result = new AsyncClass(this).execute();
and then a method that return back a string. But I can't do that because i got:
Type mismatch: cannot convert from AsyncTask<String,Void,Void> to String
I just about got this, but I have a small problem in the order of things going off.
Specifically, in my thread() I am setting up an array that is used by a Spinner. Problem is the Spinner is all set and done basically before my thread() is finished, so it sets itself up with a null array.
How do I associate the spinners ArrayAdapter with an array that is being loaded by another thread?
I've cut the code down to what I think is necessary to understand the problem, but just let me know if more is needed. The problem occurs whether or not refreshData() is called.
Along the same lines, sometimes I want to call loadData() from the menu. Directly following loadData() if I try to fire a toast on the next line this causes a forceclose, which is also because of how I'm implementing ProgressDialog.
CODE:...............
I tried changing onCreate() to the following after Jims suggestion.
Not sure if I did this right, still doesn't work:

I'm trying to make a simple ProgressDialog appear while my AsyncTask is fetching data. In my onPreExecute() method I have this: pd = ProgressDialog.show(c, "Loading...", "Please wait");
c is the context passed into the constructor of my AsyncTask from this.getApplicationContext(). Unfortunately, I keep getting an exception with this message: Unable to add window -- Token null is not for an application
What am I doing wrong?
Using this instead of this.getApplicationContext() has revealed another problem. When I call ProgressDialog.show(..., a ProgressDialog is displayed, but not until after the AsyncTask has completed. In other words, the data loads and then the dialog is displayed. If I include pd.dismiss() in my onPostExecute() then I never even see the dialog (presumable because it is closed before it ever gets opened).
It turns out that fetch.get() was hogging the UI thread and not letting the ProgressDialog display.
I'd like to change the rotating image inside the ProgressDialog.
In the documentation this is suggested:

This can be changed with:

I uploaded the new updates to the application in the market. There was no error message shown. It seemed that the uploading was successful. However, the version name and the app itself were still the old version. FYI: lost the original private key or the keystore file. I generated a new keystore file to sign the app. I also met the minSDK problem and solved it by set the minSDKversion in the manifest file. There must be a way to update the app. I don't want to upload the app as an new application since there is a large base of existing customers.
Im trying to show a ProgressDialog while the activity is loading. my problem is that although i completed all the work in the activity. it takes a long time for the activity to load, i suspect this is because i use
multiple views with multiple listviews with custom array adapters inside a viewflipper. it takes a long time for the UI to show.how would i go about checking that all the UI inside the activity finished loading? or is there a way to preload all the activity and the UI?
I am developing my first Android App and I need a ProgressDialog to be showed while a background task, in this case just a http call on the server, happens.
I did a bit of studying on this and also have already checked other threads related to this subject.

Among others.
Than I got to write a bit of code:
1) In My Activity I declare a variable to be of type ProgressDialog
code:............
2) I have also written an inner class to extend AsyncTask as required, here in the doInBackGround is where I call a static method which actually do the POST http request to the server, in the server side I have blocked the server response 20s to validate the progress dialog.
code:............
3) When the button is pressed I than build the ProgressDialog anc call the AsyncTask I have created:
code:...................
Well, this is it, I believe this was suppose to show a progress dialog while the AsyncTask would query the server in background, but what I get is NO progress bar until server response arrives and than for a fraction of time(less than 1 second) the progress shows and the next Activity is called.
