App Widget layouts are based on RemoteView, which does not support every kind of layout or view widget:

I am going to assume that those are screenshots of Android home screens, showing some app widgets.
You cannot cause an app widget to be added to the home screen. After all, not all home screens offer app widgets. The user would have to set up the app widget themselves.
Given that the user set up the app widget, you are welcome to populate it based on a long-click of a list row in one of your activities. Use AppWidgetManager and updateAppWidget() to push a new RemoteViews to the app widget based on what the user long-clicked on.

I've problem, that i want to create a home screen widget with listview inside, which should be scrollable. I read on docs page, that listview is only supported in remoteview from 3.0 android.
But still i think, this is not completely true, or i am missing something. Ok, when i tried do add listview to my home screen diget, i get error: class not allowed to be inflated android.widget.listview. BUT on my phone i have android 2.2.3 and i am able to add home screen widget (its some email application widget) which shows SCROLLABLE list of my emails, look here:

And my question is: How is this possible and how to do it, in which way? Im googling few hours, but have absolutely no idea how is this possible (maybe dynamically generate items int vertical linear layout and create manualy scroller on right side, but it sound terrible complicated).![enter image description here][1]
EDIT: maybe its possible to generate long list of items into linear layout and detecting, if user is moving up or down with finger...

Correct.

That is not an app widget. That is a feature of that home screen implementation.

No, sorry.
I am building a home screen widget and I want to add an advertisement to it. Currently the advertises SDK provides a custom view widget which I tried to embed in my home screen widget. But when I add it, it says problem loading widget. I'm guessing I can't add custom views to a widget? Could someone clarify or tell me how I could add an advertisement to my home screen widget.
Thank you
Home screen widgets support very limited number of standard widgets. You can't use custom widgets for them. See App Widgets.
I'm been trying to figure this out for a while now, and have just become more and more confused.
I have made a Android Widget which displays two articles (title + image). In addition to this, I have buttons for flipping backward and forward through the articles. What I don't understand is how I can change the Widgets RemoteViews when the buttons are pressed. Which should be one of the most basic operations in a widget, however, I can't seem to figure it out.
So...
Can I do this with just a OnClickListener in the AppWidgetProvider?
Or do I have to create an Activity without a window (visibility = false)?
Please excuse my stupidity. This is probably very basic.
I don't think this is basic at all - it's something I thought about for a while in relation to the Headset Blocker app I wrote, which is just a widget that you toggle on/off.
I ended up looking through Google's source code for what they did. The answer is to use the AppWidget's receiver nature to receive updates via setOnClickPendingIntent(). Then in onReceive(), you react differently to your own clicks than someone trying to create a widget. You can see a sample of what I did in the Headset Blocker source.
Ultimately, an Activity or a Service is too heavy weight for what you want. Using the same BroadcastReceiver as the app widget itself is much better.
