This seems like a pretty simple question, but I'm not sure if it's even possible. Is it possible to allow the MENU button to still bring up the option's menu when a dialog is showing on top? I want to do this because I want to give the user some more options while a dialog is opened.
I don't think that is possible.
Although the docs say that you should be able to do this.
A dialog is always created and displayed as a part of an Activity. You should normally create dialogs from within your Activity's onCreateDialog(int) callback method. When you use this callback, the Android system automatically manages the state of each dialog and hooks them to the Activity, effectively making it the "owner" of each dialog. As such, each dialog inherits certain properties from the Activity. For example, when a dialog is open, the Menu key reveals the options menu defined for the Activity and the volume keys modify the audio stream used by the Activity.

I wanted to create an options menu as seen in this image: http://i.imgur.com/Mf0PSy8.png
But the problem is, the only way that I found to create this type of menu is by calling onCreateContextMenu method and I don't want it to only appear when user long-press an item.
I want it, for example, to show up when user click a specific button linked to a function.
How can I do it?
You can explicitly show the option/context menu programmatically by calling Activity.openOptionsMenu() / Activity.openContextMenu(View view).
You're looking for a Dialog Fragment. These work just like a Fragment class but can be displayed as a dialog. You can find more on using a Dialog Fragment in this tutorial to do whatever you would like
I have read really a lot of posts about this topic, however nothing works for me (or doesn't have the effect I wish).
I have a an application, that after logging in starts a background Service (implementation of the Service class). This service syncs itself with a Server and if a new order comes, it creates a notification.
So far, everything works great, I have the notification and the Toast message. However, I would like to have a dialog, that notifies the user about the new order.
As I understood, you can start an activity from within the service, which displays the dialog. This works, but the activity starts on top of the current activity stack and displays the dialog. I have an activity with no view attached and it correctly displays the dialog, however, on a black background.
What I want is to display the dialog on the current activity, causing the actual background(the running activity) to fade and display the dialog.
Is this somehow possible?
We can show dialog from service only if it is a system alert dialog. So, set TYPE_SYSTEM_ALERT window layout parameter to Dialog as follows:
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
But, it needs SYSTEM_ALERT_WINDOW permission. So, don't forget to add this permissin in Manifest file.
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
Edit:
Better option to show dialog is to start activity as one of the below ways.
Start Activity with Dialog Theme (android:theme="#android:style/Theme.Dialog") -(or)
Start Translucent Activity and show Dialog in it.
Note: You should add Intent.FLAG_ACTIVITY_NEW_TASK to intent
I highly, highly, HIGHLY recommend that you DON'T do this (it goes against Android design and UI guidelines). Notifications are the preferred way to accomplish what you are doing (which it sounds as if you have already accomplished).
That being said, if you must do it, I would recommend just using a Dialog themed activity. That way you don't have to start up a separate dialog. Please see http://developer.android.com/guide/topics/ui/themes.html#ApplyATheme for how to do this.
you can start by learning on how to create an activity that looks like a dialog (no title bar, transparent background, "floating" effect, etc.)
and no, you can't just start a dialog without an activty
No, you can't hijack activity that is not "yours" and command it to show dialog.
Your approach of starting your own activity is the classic one.
You cannot show a dialog. But you can go the alernative way by inflating your customized view so that you can show a dialog on the screen whenver certain conditions are met.
I've searched around for a while on this but haven't found anything. I have an "about" option in my app's main options menu that gives the user support information (# to call, version info, etc). I also have an alertdialog that prompts the user to take an external action before the app proceeds (they have to do this). It's possible the user may want to get this support information while the alertdialog is present. Is there any way to make the alertdialog not block the app's option menu? Or maybe just show the options menu on top of the alertdialog somehow?
edit - not on top of the dialog itself, in the same spot it would normally be, just on top of the overlay.
I ran into a similar problem with a dialog and sound. My problem was that when the dialog appears, it caused the original activity to pause, which had unintended consequences.
In my case I found it easier to implement my own dialog interface using a RelativeLayout and FrameLayout within the original activity.
I am using a dialog themed activity in android to show a popup from a application context. The dialog has a transparent theme, but the issue is that I want the underlying activity to have focus and not the popup though the popup must be visble. How do I achieve this in android?
I think you would have to use a Fragment and just make it look like a popup dialog.
You can not switch focus between activities. There's only one activity "on focus" at the time, and is the one that is being displayed at that point. The transparent background doesn't mean you can access the activity below.
If i don't get it wrong, you want to be able to interact with the activity's controls while having a "Dialog" on the screen. Any sort of Dialog class from Android will not help, since they take the focus away. Not really sure about PopupWindow, but i'm guessing will be the same thing as the documentation says "that appears on top of the current activity."
You are going to have to create a custom dialog using a RelativeLayout/FrameLayout within your activity.
The Title is almost the entire question but i'll complement it with some things :
-(1) I have a AsyncTask for get some data from Internet
-(2) I have a AsyncTask for display a Progress Dialog
Before call (1) , I execute (2) dialog.show() and when task (2) ends I call dialog.dimiss(). All is doing right , but while the Progress Bar is showing the Menu Button stay unresponsiveness, ie , nothing happens...
I would like to know if it is the default behavior or i missing something ?
I'm looking for it and did found anything that clear me about it..
Aprecciate any advice
You mean to say that while the dialog is showing, pressing the hard menu button does not bring up the menu. Did I get it right?
If so, then I see the same behavior as you. But according to this:
For example, when a dialog is open,
the Menu key reveals the options menu
defined for the Activity and the
volume keys modify the audio stream
used by the Activity.
So I would expect that the menu button should still work even if the dialog is showing, but based on my experience, it does not.
After the dialog is dismissed, the menu button should work again.
onCreateOptionsMenu is meant to prepare the dialog. Once it is shown and in use it is no longer being prepared and thus use of the dialog is then handled in onOptionsItemSelected.
