I've got a quite interesting issue when I try to display a ProgressDialog (the simple, spinner type) within a onPreferenceChange listener.The ProgressDialog shows up, but not until the method (sleep in this case) has finished. What am I doing wrong?

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.
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 have pretty unassuming preferences screen based on Preference Activity. (You can see it in DroidIn app) I'm having some problems with it that I think have to do with redrawing the screen after updates. Here are the symptoms: 1. OnPreferenceChangeListener#onPreferenceChange if I change summary of the preference by doing Preference#setSummary the new value is painted over the old one creating unsightly effect 2. My preferences screen is large enough that user has to scroll. While scrolling, the whole screen get all messed up, again it looks like view is redrawn (when scrolled) without erasing the background first.
View 2 Replies View RelatedI've created a set of preference screens building on the tuts on androidguys. My preference XML contains nested PreferenceScreens. The below doesn't occur in the root screen, only once clicking to a child PreferenceScreen. Once in that PreferenceScreen, even before selecting an EditPreference, if I change orientation (i.e. flick the G1 keyboard out) I get an error: 01-30 09:33:54.080: ERROR/WindowManager(1261): android.view.WindowLeaked: that was originally added here.I have previously overcome this in other activities by utilising the onPause etc methods with custom dialogs I use. How can I prevent this in the PreferenceActivity? What am I missing?

PreferenceActivity class automatically saves user preferences, so in widget update service i can call context.getSharedPreferences() and i obtain user preferences.Problem is follow: if you have many widget of same type, how PreferenceActivity class saves prefs? how i can load appWidgetId specific prefs from sharedPreferences?

It seems that they store preferences as "default" preferences only. I would like to use a PreferenceScreen as my configure activity for an AppWidget, but I need to be able to store distinct preferences for each widget.

1.application title-bar using ImageView(or TextView) positions to top
2. remove ContextMenu, alternativly static menu buttons positon to bottom.
3. PreferenceActivity is able to scroll and title-bar & menu buttons are fixed each positions.
just all. but It's very difficult to add & fix two views in Preference Activity.
I have a problem in the Preferences Activity, in the main preferences the theme shows ok, but if I get to a sub preference, the theme gets messy, it is not white as it should, it is all dark, and the font is black so you can't see much, and when I start clicking on any items they will get sometimes white as they should but revert to black soon after. This is only happens on 2.1, in both the real device and emulator. Tested on the emulator running 1.6 and it was working correctly.

View 6 Replies View RelatedI think I've missed something in how Android is supposed to work! I have the main Activity with a menu option that opens the preferences screen. What I need is a way for any changes that were made to be communicated back to the main Activity as soon as the preference is activated. At the moment the only way I could get it working is by using the intent data that gets sent back when the prefs activity closes but this isn't really enough. The reason why it needs to be instantaneous is that one of the preferences is a 'Clear cache' button, so I would like the data to be deleted when the user requests it and no later!

View 1 Replies View RelatedIs there a way how I can tell the Preference Activity that value should be saved as integer? So far my all values are saved as strings... I can limit input to integers via XML easy:
<EditTextPreference android:key="SomeKey" android:numeric="integer" />
but it is still saved as string and later trying to getInt("SomeKey") on preferences object I always get java.lang.ClassCastException: java.lang.String.
Is there a way that EditTextPreference value would be saved not as string? Or maybe I should use some other type of Preference for numeric input?
I encounter a problem with a ProgressDialog in a PreferencesActivity in my application.What I want to do is pop up a ProgressDialog after the user has changed his username or password during the check on the remote server. In the onSharedPreferenceChanged() I call the ProgressDialog.show() method. Sometimes it works fine, sometimes not at all.

I have a widget which starts an activity when it is clicked. I'd like to have some kind of fancy animation to display this activity, rather than the standard scroll-from-right of Android. I'm having problems setting it, though.But then where do I reference it from? I've tried both the base element of the activity I want to slide in, and the activitiy's entry in the manifest,I might be doing this all wrong. Any help is much appreciated!
View 2 Replies View RelatedI want to display the status of the activity execution on the screen using the TextView while activity is executing. I am appending the String messages at different stages of execution in the TextView, which is defined in the Layout main.xml (e.g. TextView.append("Server started..").
For e.g. I am running socket communication application in which my android application is the server and it is receiving the messages from the local desktop. So in this application I want to show "Server started.." message when socket server on android started , then a messge "waiting for message.." and then "message receivied.." when message received by android server.All 3 steps are the part of a single activity.
But in my case, I am getting all 3 messages at a time after activity execution completed. Is there any API available, using which I can show the status during the execution also.
I am using a PreferenceActivity to show some settings for my application.I am inflating the settings via a xml file so that my onCreate (and complete class methods).These preferences will automatically save to SharedPreferences as the user interacts with them. To retrieve an instance of SharedPreferences that the preference hierarchy in this activity will use, call getDefaultSharedPreferences(android.content.Context) with a context in the same package as this activity.
View 4 Replies View RelatedI've a Preference Activity which works perfectly the first time i launch it.But if i close it ( with the back button ) and then i re open it ( through a menu click in the main activity ) then i get a black screen. There is no preferences at all.I can't figure it out why it should not working.It seems all the code is being called normally as the working one but no preferences are showing on the screen.
View 1 Replies View RelatedI'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 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?
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.
