Consider the following use case. Activity 1 starts Activity 2. Activity 2 is currently in foreground. Now, Activity 1 wants to display a Dialog. Is it possible for Activity 1 to display a Dialog? What will be the error display, if any?

I'm looking for a little more information about dialogs managed by activities than is provided here:
http://developer.android.com/guide/topics/ui/dialogs.html
And havn't found any good web resources. In particular, I'm having a problem where a dialog must be updated in onPrepareDialog() with Activity member variables that change after onCreateDialog() is initially called. During an orientation change, version 1.5 will only call onCreateDialog() and not onPrepareDialog() for dialogs previously used (and not dismissed).
An example problem scenario's onPrepareDialog() steps are listed here:
CODE:.............
The result of not calling onPrepareDialog() during orientation change, if the dialog is currently being displayed, is an empty spinner.
In 1.6, onPrepareDialog() is also called and so this problem is not seen.
As a workaround for 1.5 I simply remove the dialog in onResume(), but obviously if the dialog is showing on orientation change the user experience is not ideal.
I don't expect this is a 1.5 bug so much as a lack of my understanding regarding what the "right thing to do" is in such a situation, where information is not known at dialog creation time.
Does anyone know if it's possible to get a Dialog box to display between activities? I've looked and haven't been able to find a solution.

View 2 Replies View RelatedI am having a problem about repeating Login dialog (an AlertDialog) and progress dialog, coordinating with http thread. I suppose repetitive Login dialog (if fail, continue) handling should be common and straightforward. I guess my approach must be wrong somewhere. I already spent 2 days on this and am desperate. So please help. User starts the app, the main activity starts.Show a login dialog (generated by the main thread, i.e. from on Create. The main thread then starts a wait_thread, which will wait for http to return data and check the data and decide what to do.After user input username/password and press login, a progress dialog starts.The progress dialog starts an http_thread to talk to the server and get replies. Once done, it will notify the waiting thread.If the user type in the right username password first time, the code works fine.But it always fail for 2nd time Login, i.e. When first login fail(wrong username/ password),the wait_thread will generate 2nd Login dialog to let user repeat the login process. But after user hit the login on this 2nd Login dialog, the system always crashes.

I'm trying to get my list view to open up an alert dialog to display information when a person clicks on a selection. I have been trying several different things on the Google Developers website that have to do with this but have yet to come up with a result. Here is my code. package table.periodic;
import android.app.Activity; import android.app.AlertDialog; import android.app.Dialog; import android.content.Context; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.ImageView; import android.widget.ListView; import android.widget.AdapterView.OnItemClickListener;...........
how to create an Alert dialog in a dialog? is it possible to create? My requirement is to show mulitple dialogs simultaneously. I tried creating with the following code snippet onClick of a Button in the first Dialog and got an "BadToken" exception from WindowManager: "Unable to add window -- token null is not for an application"
AlertDialog.Builder builder = new AlertDialog.Builder(getContext()); builder.setTitle("Test Title"); builder.setOnCancelListener(new Dialog.OnCancelListener() { public void onCancel(DialogInterface dialog) { dismiss(); } });
I have a really weird problem, which I am unable to debug so far. thing is. my app needs to download something to work. So in the beginning of the onCreate() method, I check if that something is already downloaded. If not, I pop a dialog up asking the user to download it.My dialog is shown and I am clicking, so aManager.install() is called. I am passing the context because that aManager.install() pops up a ProgressDialog to show downloading progress and spawns a new thread in which everything is downloaded. So obviously before creating my dialog I make a Handler to receive the response from that aManager.install(). And the response MAY vary, because for example the internet connection isn't available (Exception raised and catched and listener called with different code).Now, when that happens (Exception) I would like to call another dialog saying "something went wrong, would you like to retry?" so another call to showDialog(DIALOG_REINSTALL) (this time with another code).thing is the showDialog() gets called (I can verify this by logging) but the dialogs doesn't show up. Instead my application JUST HANGS Does someone have a clue why it's doing this? No exception raised, absolutely nothing from logcat, I can't tell WHERE it's hanging...just see that the method is called and the dialog should be displayed.

View 1 Replies View RelatedI have an Activity which is an OpenGL view. I also have an xml layout to use for preferences. Until now, to show the preference menu, I just brought it to front by setContentView(). And the same to get back to the OpenGL view. But is this a case where I should give the preference menu its own Activity? I guess this would make a few things much easier. For example, the back button would just work, opposed to now where I have to code it or it will just exits the application.And if this is a good idea, how do I pass data both ways? I have a class that store all preferences. Can I send it to the Activity and back again? Or is the best way to store the preferences in a sqlite database and then use it for passing data?

View 3 Replies View RelatedI have an application with three tabs. Through various interactions with the items in the tabs I end up launching other activities. The client has reviewed this and would like the activities launched "within" the tabs, so the tabs remain visible and if the user clicks the tab it goes back to the original activity defined in the setContent function. Is this possible and how would I go about this from other activities? (ie the child activities, not the one that defines the TabHost and has access to call setContent)?

View 1 Replies View RelatedI need to have two activities in an Android app that can be switched between each other with UI persistence.I would like the changes made in step 2 to be visible in step 4.I have tried using the singleInstance activity tag on Activity B to no avail. I would also prefer a more elegant solution than simply writing all object properties to a file or SQLite table.It seems that this behaviour must be easily achievable given that Android does it automatically for calls to onBackPressed() where the parent Activity's UI is saved.

View 3 Replies View RelatedI am working on an Android app that has multiple screens the user will need to navigate between and I am curious what the best practices are when switching between those screens. I am torn between creating a new Activity for each screen and simply changing the view (setContentView(R.layout.whatever)). The screens all share at least some variable values so I'm leaning toward changing views and using class level variables, but I'm worried a single activity could become very large and confusing with logic for multiple screens in a single file. I'd like to keep the code clean and separated, but I also don't want to be passing several variables around between views if that isn't needed.Being new to Android development, I'm hoping some more experienced members of the community could share their thoughts and let me know how best to handle it
