Sorry for beginning a noob but how do are do this with a small Activity/box where you can still see the background like in the image below. Are there any examples? Any help would be awesome. Thanks
This is a Dialog
http://developer.android.com/guide/topics/ui/dialogs.html
A dialog is a small window that prompts the user to make a decision or enter additional information. A dialog does not fill the screen and is normally used for modal events that require users to take an action before they can proceed.
Declare this code in your activity in manifest file then it becomes dialog
android:theme="#android:style/Theme.Dialog"

I want to add an dialog to my application. I want it to launch as soon as the first activity loads. But instead of having just a single message to display and having a 'yes' and 'no' button like this
I want it to display a list of message like this
If there is a tutorial that speaks on this subject I would be happy to look at it and also I would anybody by any chance know how to align these list with bulletins.
1 Create a custom dialog layout (XML file).
2 Attach the layout to Dialog.
3 Display the Dialog.
4 Done.

Your best bet would be to start Here in the Docs. They show a great example of doing it with a Dialog.
Another option, if this can be the entire Activity since you want it to happen when if first starts, is to use a ListView for your Activity and use setChoiceMode() on it. You can find more about that in the Docs
With this second option, you can make the Activity appear as a Dialog by adding this line to your <activity> tag in the manifest.xml
android:theme="#android:style/Theme.Dialog"
I'm developing an app that includes reviews of items and due to my design, I want to only show all the reviews in a popup window like in Google Play Store:
What should I use to create that white panel that appears over the current window and contains the necessary information? This should be simple but I'm a newbie and I can't seem to figure out what this "widget" is. Please help me if you are familiar with this so I can use this cool design pattern. Thanks.
It seems you want to display a layout as a popup in another activity.
If you want to do this using an Activity instead of a Dialog, you can do this by setting the activity's theme to android:theme="#android:style/Theme.Dialog" in the manifest - this will make the activity appear like a dialog (floating on top of whatever was underneath it).
A better way to do it would be using a DialogFragment. You can display information in the form of a popup and it will have its own lifecycle. That will be much better than displaying an activity like a dialog
Ram kiran's answer is a good one and one which I like to give also. But just so you have another option to look at you can consider PopupWindow
As stated in the docs, it is
A popup window that can be used to display an arbitrary view. The popup window is a floating container that appears on top of the current activity.
I've used this and it works out nicely in some situations. It really depends on what your exact needs are as to which will work best for you.
I have an android application which uses a custom Alert Dialog for showing an image and its description.
I want to make this dialog
Pop up from center like in iPhone.
Push down to center when cancelling.
I know that it is possible by applying animations/styles.How can i make style for this purpose?How to use this?
Thanks in advance
Dialog, was defined in doc, is a small window that prompts the user to make a decision or enter additional information. A dialog does not fill the screen and is normally used for modal events that require users to take an action before they can proceed. With it's subclasses (AlertDialog, ProgressDialog, AppCompatDialog,...), they become a alert system in Android. For making more exciting when they appear/exit, we can set animation for them easily. In this tip, I provide a way to do this trick through styles resource.

I want to show a small Custom Dialog on top of the current user activity, but have clicks to the area outside of my Dialog delivered to the background (which would be the launcher, or another activity). I tried to create a transparent base-activity and have the Dialog shown on top of it, but clicks are registered on the transparent activity and not on whatever is behind it...
I know that a Popup has a setOutsideTouchable-Method, but setting this to true just dismisses the popup, rather than delivering clicks to the background, to my knowledge...
Thanks for your help,
Nick
Based on this clarification comment you posted on another answer...
"I want the Dialog to be shown system-wide, no matter which App the user is using at the moment..."
I don't believe what you want to do is possible and I'm happy about that. :) If you were allowed to popup a little dialog box over anyone else's app and still have the user be able to interact with the current activity... then you could easily trick the user into thinking that the little popup belonged to the current app and not yours which is acting from the background.
Imagine all of the evil you could do with something like that. Prompting for the user to reenter their email password when they are in the Email.app.. and then just storing it for malicious purposes, etc.
It isn't possible.. and SHOULDN'T be possible. If you need to notify the user of something, then you should use the built-in notification system. That's why it is there! :)
You can use a PopupWindow "Dialog like" and show it for the user in top of your activity. The outside events will be delivered to the main Activity.
I can't see the deeper meaning of exploiting the using the given usability patterns of android by doing what you ask for?
It is recommended and meaningful to stick to common patterns so users don't have to adapt in basic apps. That is, unless you are working on a game:)
"I want the Dialog to be shown
system-wide, no matter which App the
user is using at the moment..."
That is what the notification system is for. It allows you to tell something to the user without interrupting him in whatever he was doing.
System wide dialog popup are evil and gladly not implemented in Android.
Use the notification system : http://developer.android.com/reference/android/app/Notification.html
Also if you are ok with only a dialog above YOUR app, then the simplest way to let the UI be still responsive while your dialog is up, is simply to recreate a dialog in a relativelayout view and display this instead of the common modal dialog.
You could switch places so that the popup is actually "behind" the initial screen, but then set the initial screen as transparent.
Edit: This would only be applicable within an application of course.
I am trying to create a small pop-up in my Android application to let the user choose from one of many items, ala a ListView. I am hoping to make it show up as a translucent box that overlays on the screen, as opposed to completely occupying it like Activities usually do.
One technique for doing this that I've heard is possible is to launch an Activity in an AlertDialog box. This would be perfect - it's the ideal size and has a lot of the mechanical properties I'm looking for, but I'm totally unable to find any more specifics of this technique.
Is this possible? And if not, what is the preferred way of accomplishing something like this?
This should answer your question: http://developer.android.com/guide/topics/ui/themes.html
Quote: For example, you can use the Dialog theme to make your Activity appear like a dialog box. In the manifest, reference an Android theme like so:
<activity android:theme="#android:style/Theme.Dialog">
Maybe you could just display AlertDialog http://developer.android.com/guide/topics/ui/dialogs.html
