What View Component does the Google Plus App (Stream) use? - android-layout

if you use the Google Plus App on Android and switch to the Stream, you get a view where you can swipe to the left and right between the All circles/Incoming/Nearby-Stream. What view component is used for this? Is this a standard Android component? Or where can I find democode how i can build such a view component?

You should take a look at the ViewPager from Android Compatibility Package for the desired widget/swipe navigation. Find more about it here
http://developer.android.com/sdk/compatibility-library.html
Also, checkout this recently posted tutorial and some sample code on ViewPager by Richard:
http://geekyouup.blogspot.com/2011/07/viewpager-example-from-paug.html

It is a combination of a ViewPager together with an indicator for where you are currently and where you can go swiping left and right.
A sample of how this can be done along with code you can use in your own apps may for example be found here. I've played with this code a little and it works pretty well.

None of the default widgets/views. I guess, it's some kind of a custom view with swipe functionality.
Honeycomb opens up a few new widgets which seem to have these functionality. Have a look here.
http://developer.android.com/sdk/android-3.0.html (New Widgets)

I used APKTool to take a look at what's going on. Hopefully it is okay to post this here. This is from version 1.0.2 of the G+ APK.
removed google+ app code as per CommonsWare's suggestion
So, it looks like they're using standard views, though perhaps with a good deal of gesture detection and smooth animation magic.
EDIT) If you really want to know about the exact inner-workings of what is going on in the Stream activity, I suggest you use APKTool yourself and examine the .smali code

How do I declaratively push BottomSheet with Navigator 2.0?

I'm new to Navigator 2.0 in Flutter, and now I'm trying to achieve BottomSheet behavior using declarative approach. Unfortunately, I only managed to come up with quite a cumbersome way to do that so I'm wondering if there's an easier way.
I'm building a shopping app and I want to show the item details card that slides out from the bottom of the screen, dimming the previous page (as shown in picture), when user taps on item in a list. I also want to allow url support, so that /item/id opens home page and then shows the details card over it.
So how I think this could be done is to push (or to add to Navigator's pages array in case of Navigator 2.0) custom non-opaque page with no transition animation using TransitionDelegate and PageRouteBuilder, and then animate dimming and sliding by hand using animation controllers. But this approach seems unnatural (and genuinely scares me to be honest) and it's still not clear to me how to handle back button in this case (Do I need to somehow notify the page to play closing animation from Navigator's onPopPage, is this the way to do this?).
If anyone has an experience of implementing similar feature, I would really appreciate sharing it! Or maybe you have come up with more elegant solution, then tell me about it and I'll give it a try! Thanks!

Can I skin the Activity Dialog to have a custom animation?

as explained in the title I would like to know if I can set a custom animation and/or background for the Activity Dialog. I don't find in your documentation any information regarding this... and further than that I have problems setting the Theme... it doesn't matter which theme I set, always see the same.
All this look the same:
DialogTheme.DEVICE_DEFAULT_LIGHT, DialogTheme.MATERIAL_LIGHT, DialogTheme.DEVICE_DEFAULT_DARK...
I use the following code:
_activityDialog = Dialog.service.create(
new ActivityBuilder()
.setTheme( new DialogTheme( DialogTheme.DEVICE_DEFAULT_LIGHT))
.build()
);
Thanks in advance for any help
There is no way to control the animations of native dialogs at this point.
The themes are applicable only to Android and depend on the version of Android you are using.

Questions about Citymaps

1、I want to create a circle and set an image that customized to fill the circle,use this as a marker on the map, not only could change the image but also the color of circle anytime,what can I do to implements this function? Please look at the picture below!
2、Like your CityMaps app show,when I enlarge the map, some business icon that hide are show on the map,which are hide again while shrink the map, How to achieve this effect?
3、After I initialization the Object Marker and called the method marker.setFadeTime(3000),the software give my tips the method is no exist and I see the class Marker.java but really not find the method,Why is it so?
4、I want to add some stars beside the marker like this:
What can I do to add the stars?the label only can set the text beside the marker.
5、I want to load your maps at the fragment,not the activity that extends FragmentActivity,I found the SupportCitymapsMapFragment is no use,What I can do to complete this requirement?
6、In your apps,it is locate that place after input New York in the search box,What can i do to complete this function whatever i input?
7、During I develop the apps about the Citymaps,I found a serious problem so that your apps had happend too. When I run the apps, the program force flash back all of a sudden and I run your apps Citymaps at this time,the problems are same of the front,I found some error in logical view that is follows:15327-15374/com.map.maplbs A/libc﹕ Fatal signal 11 (SIGSEGV) at 0xdeadbaad (code=1), thread 15374 (Thread-1819).
To solve the problem,I must restart my device. Why is it so?
I am a developer on the Citymaps SDK, I will do my best to answer your questions.
1) I recommend using the Android Canvas API to construct the images, and then use a Marker to display it on the map. See the documentation for details: http://developer.citymaps.com/markers
2) This is built into the Citymaps BusinessLayer. This functionality is not exposed through an API. If you wish to use the Citymaps BusinessLayer, you should create a CitymapsMapView or CitymapsMapFragment/SupportCitymapsMapFragment and it will automatically be added to your map.
3) At this time, there appears to be a known issue with the fadeTime API. Thank you for bringing this to our attention. We will fix it in an upcoming release. For now, you can animate the alpha property of the Marker.
4) Once again, the functionality of the BusinessLayer is not directly exposed. If you wish to create similar markers, I recommend you construct the image using Android's Canvas and then adding it as a Marker to the map.
5) If you wish to load the map inside of a fragment, you can accomplish this using child fragments (check Android documentation for more details). You can also accomplish this by instantiating CitymapsMapView or MapView directly and adding it to your view hierarchy either in XML or in code. However if you do this, remember to call the lifecycle methods on your map instance, or else the map will not behave properly.
6) If you wish to have a search in your app, it is up to you to implement this feature. We do not currently provide a search API out of the box.
7) Thank you for the bug report. We will investigate this issue and fix it in a future release.
If you have any more questions, feel free to ask, and thank you for using the Citymaps SDK.

expandable (month view)/collapsable(week view) calendar widget for android

I saw this android calendar widget used in an app called cal and was quite impressed.
I would like to implement a similar one in my app as well. Currently I am using an android calendar framework called caldroid and I am using it as a Fragment and will be invoked on action bar button click and will get collapsed clicking back on the action bar button.
But I would like to do the widget like in the app. Screen shots attached.
I would like to know if you guys are aware of any frameworks that can used to achieve this or any approach or tips on how to code this.
I am bit new and know basics of android. Haven't attempted to create custom widgets yet.
Thanks,
Bala
Maybe this library can help you.

Create Custom view in Android

I need to create a Custom view in android which will have dynamic text like price, address etc. and also an ImageView inside it as shown in the image below. I tried to find google some tutorial for custom view but didn't find something satisfactory to do all these things. I also need to use onClick event on this view. Please guys, some code would be of great help. I'm a novice to android. I read google tutorial to create custom view but couldn't implement this.

Thanks for attention.
This is called Custom Overlay for MapView.
You can check example and implement as per your requirement - Android MapView Balloons
You can use FrameLayouts. It is very simple to use. FrameLayout can add several views on top of each other. It creates a stack of the views. Just add whatever views you want to inside FrameLayout and use the property setVisibility() to control when to show which view.
