Android :: SubMenu - Dialogs And ActivityGroup
May 31, 2009
I have 6 options to put in options Menu, but 3 of them are not so important and i want to hide them in submenu. All of my Activities are started from one ActivityGroup which creates Menu on MENU button press. Problem is that when I open SubMenu or Dialog (which is created and displayed by ActivityGroup) my current foreground activity makes onPause, onStop and onDestroy, and when I close this submenu (using "back" key) or dialog (by "ok" button for ex.) I don't have any response (onCreate, onResume) from any of my activities registered in LocalActivityManager.

I know you can create shortcuts to the main Settings menus (battery use, bluetooth settings, etc.) by just long-pressing the screen -> Shortcuts, but I need to create a shortcut to a submenu (specifically Settings -> Wireless & Networks -> Mobile Networks -> Network Mode) This is on a Droid 2 Global. Anyone know how I can do this? I have LauncherPro and I know you can make shortcuts with it but programming those shortcuts seems pretty complicated. Also I know you can make additional shortcuts using the LauncherPro "Activities" menu but I can't find the "Network Mode" settings in that list either.

I want to add a MapActivity in an ActivtyGroup. As only single level inheritance is supported, my class can either extend from either MapActivity or ActivityGroup. As far as I know MapActivity is not a part of ActivityGroup. I want an activity to extend MapActivty as well be a part of an ActivityGroup.

I need a to create a layout that holds to other layouts. each one of the layout should be populated by a different activity.
I've done some research and came across the fact that I need to implement an ActivityGroup and use it's LocalActivityManager. problem is that I don't understand the View hierarchy in such a situation. a naive attempt to find the view of the parent window (simple findViewById) fails (returns NULL).
I can't find any examples on the web. have anyone done it before?

So I have a default searchable Activity in my app, and if I press the search button in simples activities it works. But when I'm in a tab where the content is an ActivityGroup, and not an Activity, the app crashes.
CODE:..............
Even if I add this code in my activityGroup, I'm still crashing :

I am using an ActivityGroup and when I finish a top-level Activity (e.g. with destroyActivity method) and display one from history, the getCurrentActivity method returns the last Activity - the finished one. I need to access currently displayed activity, which is actually shown.

I have one problem using ActivityGroup. I have two activities inside an ActivityGroup and both of them use a menu (overriding the onCreateOptionMenu and onOptionsItemSelected).
Well, the problem is that the second activity in the group doesn't show the menu when I press the menu Key. The first activity works fine showing the menu.
I have this code in child activity:

I'm trying to give my first steps on working with ActivityGroups. To be more specific, I have a parent activity with a layout containing several buttons, and another layout below them in order to add other activities' layouts by means of the "addView()" method. Well, everything works fine in functionality terms; but I'm experiencing a weird behavior inside the layout where other activities are kind of loaded into. A black line along the top border of the layout plus a slight shadow do appear when I run the application on the emulator. I have tried to play changing the paddings, margins, etc. with no success.
Has any of you experienced such weird behavior?

I'm extending ActivityGroup class and implemented a custom tabHost and widgets for my app. Can someone shed a light on how are the Activities fife-time inside an ActivityGroup?.
Im getting a weird behavior when using the following code to send a new intent to the current sub-activity, then change tab, and getting back to original tab. (TAB1 -> TAB2 -> TAB1)
CODE:.......
What i see from debug..
onSaveInstanceState() is called on TAB1, then TAB2 is current subActivity, but when going back to TAB1 onCreate() is called.
onCreate() is not called with the same test without using the onNewIntent() described above.

I have a Activitygroup and some activities are part of it.
lets say Activitygroup is DetailsGroup which has a activity by name DetailsActivity.
On certail events DetailsActivity launches another activity ExtraActivity by calling startActivityForResult(intent, 2);
The extraActivity is launched it does its work and before calling finish() of it I am calling setResult(RESULT_OK,mintent);
By doing this I was expecting that the DetailsActivity's onActivityResult() would be called, but instead DetailsGroup activities' onActivityResult() is getting called.
Any idea what changes are required to get DetailsActivity's onActivityResult() called in above scenario?

I'll be brief. I have an application with the following Activities Schema:
A (ActivityGroup) | |__
B (Activity Group) | | | |__
C (Activity) | |__ ... (Other Activities) | |__
D (ListActivity) | | | |__
ListView with a custom adapter with two buttons per row
All the Activities shown on the "diagram" are displayed and visible in real time while the application is being executed.
I'm pushing new list elements from C to the ListView in D. And by clicking each row's buttons I'm trying to edit the data of the row by means of a dialog. The problem is when, in the dialog activity, I perform the setResult() and finish(); the D's onActivityResult() is never called, and I do not know why.

I am using an ActivityGroup to spawn multiple activities and switch views from within the same tab in a TabActivity.
When I press the back key this method is called inside my ActivityGroup
CODE:..............
This method allows me to keep a stack of my activities and go back to the previous one when the back key is pressed.
This is working well on all my nested activities, except on a ListActivity where a press on the back key will simply exit the application.

I have an ActivityGroup containing three embedded Activities (A, B and C). Sometimes I need to "destroy" A and B to start another one, D, and when D is finished, A and B are re-created. Is it possible? If so, how can I do it?

I have a tab bar and within one tab want to implement an activity flow (without leaving the tab screen). I tried to get this up with an ActivityGroup and it partly works, but certain commands like the onCreateOptionsMenu must be dispatched to the ActivityGroup child activity manually.
The main issue is that showDialog() in my child activity of the ActivityGroup fails with the following exception:
CODE:.............
How I can get the child activities fully working? I expect this to happen with more of the built-in activity methods and there is not much documentation for the ActivityGroup.

I'm trying to make an ActivityGroup which has it's own interface, which should be persistent between Activities.
I have it working for my own Activities. But when I try to launch a 3rd party activity (from it's Intent{action="ACTION_HOME", category="CATEGORY_LAUNCHER"}) I get a java.lang.SecurityException because the Activity I want to start does not have the same UID as the calling Activity. Does anyone knows how to cirumvent this?

I decided to share the solution i found to the problem of Android not supporting real modal dialogs.The solution was to draw the dialog by myself. :-( Well, at least worked fine, besides the problem that its a bit ugly.

I have tried to make a series of dialogs, like a questionnaire, that the user needs to answers a series of questions selecting one or more checkboxes. I can do one, just fine, but when I try to make more than one question (lets say 10), it does not show, or show all the dialogs. I tried using dialogs or new acitivities.
So, my problem is I have multiple questions, one to be presented each time, and I need to wait for one to be responded so I can ask the next one. How do I accomplish this?
My first attempt was with a dialog box... but obviously it got all the boxes stacked in each other:

I intended to show a dialog in a service process, then I tried to use the AlertDialog but got the below error message: WindowManager$BadTokenException: Unable to add window -- token null is not for an application The reason seems to be that the dialog is not used in a application context (activity should be fine?) Was there any way that can solve this problem?

I'm facing the same head-scratching moment similar to what this person (from Jan 2008) experienced when I realize that there is no cancel button in Android's progress dialog or spinners. It is now July 2009 and I've just installed the cupcake version of Android. Has this thing changed ? If not, are you adding a cancel button into the dialogs and how do you do it ?

I wonder what is the right way to implement this? Could anybody advice whether my solution is correct?
So:
Activity is created
User clicks on button and dialog is launched (Dialog, not dialog styled activity)
User opens keyboard
we have onSaveInstanceState called where we save that our dialog was opened and all respective dialog input
we have onRestoreInstanceState and here we check whether dialog was shown, recreate the dialog with respective input.
Is it the right approach? or there is smth. that is done by Android and I am doing some redundant actions.

I use the AlertDialog class in my application. By default, these alert dialogs have a transparent background. I'm trying to use an opaque background instead, very unsuccessfully.
These are my styles:
CODE:....................
I applied the "MyOpaqueActivity" style successfully for whole activities (the window background is changed to "my_background"), but it doesn't work for alert dialogs within those activities. The "alertDialogStyle" attribute and my "MyOpaqueAlertDialog" style don't seem to have any effect.
So how can I change the background of these alert dialogs?

My question is what do I need to do to ensure there is no resource leak? From the logcat, i see there is a case where it said a window is leaking or something like that.

I have an ActivityGroup with an embedded TabActivity and another simple Activity.
The TabActivity has three tabs, each one with a ListActivity.
When I try to start a search from a list (calling onSearchRequested()), I get a WindowManager$BadTokenException.
I've tried requesting focus in the list, but the same error occurred.
