Android :: Shadow On Top Of A Layout On ActivityGroup / Fix It?
Jul 16, 2010
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 have an activity. It does not have a title bar. The content view is just a linear layout. It looks like android draws a drop shadow at the top of my content view, directly below the status bar. Is there a way to stop that from being drawn?
My layout is just:
I have no titlebar:
requestWindowFeature(Window.FEATURE_NO_TITLE);

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 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 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 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've tried casting shadow following this tutorial (which uses Stencil Buffer method): http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=27 The result is a cool shadow effect. But it depends too much on geometry and thus not very flexible. Then I found a much easier way to do shadowing here: http://www.paulsprojects.net/tutorials/smt/smt.html But it uses ARB_depth_texture and ARB_shadow extension. So I bet it can't be used with Android's OpenGL ES 1.0. I've tried googling for "Shadow Mapping" and "OpenGL ES" but still can't find a good tutorial. Can anyone recommend me a good place/site I can study for this please?

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.
