is there a way to set start delay for Dynamic Animation(Spring Animation) in Android like the native animations..
According to this react-native issue Spring animation with delay from 2017 it seems that it is not possible to do.
Animated.delay supports it.

I want to identify the scroll end action, which could not be achieved through the existing APIs from ScrollView. Because, when we scrolled fast, event after the pointer/hand is taken, certain scrolling is took place on its own. My requirement is to catch the point when the scrolling is ended on its own.
I can achieve this scenario in Xamarin.Android implementing Java.Lang.IRunnable in a custom class and by using the Run() method in it. I need to achieve this in Xamarin iOS.
Could you please provide a valid suggestion for this query ?
You can use "DecelerationEnded" event in UIScrollViewer to achieve your requirement.
I'm developing (or trying to) a J2ME application. I need to be able to handle onKeyEvents (keyDown/keyPressed/keyUp...) in TextEdit/TextBoxes, but I've learned that such thing is not possible in J2me, at least not in a simple way as in Java/Android development (myEdit.setOnKeyListener() for example). I've read something about using Canvas, but I'm not sure how can I use that to make it work for me.
Answer to this question ( Image in button - j2me ) involves using the CustomItem class and make an item look/act like a Button. Is there anyway to use the same approach?
The TextBox and TextField objects are high-level GUI stuff, available when doing javax.microedition.lcdui.Form stuff.
In order to use keyPressed() and keyReleased() you must use javax.microedition.lcdui.Canvas (low-level GUI stuff).
But what you're probably really after, is LWUIT (https://lwuit.java.net). It is a framework built on javax.microedition.lcdui.Canvas which gives you a Form-like API with all the things javax.microedition.lcdui.Form is missing.
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.

Now I am developing a mobile application, I have developed menu by Canvas and I get stuck when I try to add background into application.
It means that I need to add background into my application and menu can visible on this background.
I am trying to find the way to add background into j2me, and I use array for menu and I found an example about adding background in J2me using TiledLayer and Layermanager, therefore that I just add these objects into my code for test.
Can it become a background in my code? I can not make it work that way
add background in J2me used TiledLayer and Layermanager
given above, first of all consider using GameCanvas instead of Canvas
public class MainMenu extends GameCanvas //...
Studying some introductory tutorials wouldn't hurt either:
Exploring the Game API of MIDP 2.0
Getting Started With the MIDP 2.0 Game API
By the way both above tutorials provide detailed explanations how to use TiledLayer and LayerManager for adding background
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.

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
