Is it possible to use the VideoVideo with the ListView as an item. Has anyone done this? Are there any issues I should be aware of?
I've made a test.Videoview can be inserted into a listview, it can work properly.But when i drag the list, the area which the videoview once occupied will get in front of the screen. Andt the screen will get very dirty.
Is it possible to use the VideoVideo with the ListView as an item.
I doubt it. SurfaceView -- which VideoView uses -- does not behave much like a normal widget. IIRC, you cannot have two SurfaceView widgets active at the same time, regardless of what contains them.

I want to create a simple view like this. (red circle)
I searched on internet for Bundling in Recyclerview but I could not find any resources.
Can anyone tell me the name of this view or share any tutorial resources.
Can someone share an example of how to do it. Or any Tutorials on how to get this view . - Bounty question
In recyclerview you can do this with item decoration.
An ItemDecoration allows the application to add a special drawing and
layout offset to specific item views from the adapter's data set. This
can be useful for drawing dividers between items, highlights, visual
grouping boundaries and more.
All ItemDecorations are drawn in the order they were added, before the
item views (in onDraw()) and after the items (in onDrawOver(Canvas,
RecyclerView, RecyclerView.State).

or
you can design a custom layout and inflate it using getViewByType in
viewholder
I think you better to follow this videos, i am sure my side this videos gives you a perfect idea on Android Recyclerview and also provide a solution for problem.
Please follow this youtube link: https://www.youtube.com/watch?v=XhbsNO2_oDI
ItemDecorator from example below doesn't suite you. Try to use Expandable Listview, which helps you to adjust list, when user tap on image below list item, and expand size for another item, for example, chat messages in your image.

So I have a question about best practice for dynamically creating and sizing buttons within a ViewPager, based on a changing external state.
Essentially, I have a scrolling view and I want my ViewPager to contain a number of buttons of a specific size and count depending on what part of the scrolling view is currently visible.
My question is about deciding the best implementation of this feature, I see two options: would it be simpler to
Constantly create and scale new buttons whenever the scrolling view moves
Make the viewpager itself contain a scrollview and fill it with all of the pre-scaled buttons on app startup. Then, whenever the user scrolls the main scrollview the viewpager's scrollview (which contains the buttons) will scale programatically
Any ideas on which would be the simpler and more robust system?
Not much of an answer but I will leave a comment for ya! Basically you can do it either way, both aren't to difficult to accomplish, however I would probably go the dynamic route because it will always scale correctly. Doing a set amount will only work until devices become larger, or if you are targeting tablets or tvs then it will start to become extremely messy in the xml file for the layout. Dynamically adding also gives you far more control and saves time later on, you can simply change a number and have 100 more then going through and manually adding even 10. Hope this helps!
I need to implement TextView widget in cocos2d-android-1 and don't know how please help
TextView textView = null;
textView.setText(R.string.billing_not_supported_message);
addChild(textView);
This code not working because addChild needs node. Please help really need.
I completely agree that the android version of cocos2d needs some serious 'standard UI' features adding to it.
At the moment, your only real option is to take a similar approach to my previous answer here
ANDROID:How to open web page in class extends CCLayer
whereby you have a layout which will put a textview on the screen (or you construct it yourself in your handler), and you use a handler from the activity which your scene is running in to show/hide it.
It's clunky and horrible but it works. In my field designer app i faced the same problem, but i also had to have a custom background to the text field, which resized with the text field, that had a rough edge, and the text view had to fall inside that rough edge so all the text was visible on the main bit of the background.
i achieve that using this same technique, but i created a layout xml file so that i had control over how the textview and it's background were displayed.
(note to show/hide the textview i had to give its root layout a constant ID and check for if that ID existed, and was visible, as when people touched outside it, i needed to make it vanish)
I'm fairly new to Android programming and I've got this project I need to finish and I'm currently stuck.
I've got a standard listview in a Menu class with an array containing around 20 different elements. So what I want to do is load images in an imageview depending on which item in the listview I click, and since I'm a beginner the only idea I had was to make a new activity for each imageview which seems like a pretty bad way to do it since I'd need about 20-30 new activities..
To sum things up what I want is:
Code for making ONE activity that will display a different image depending on which item in the listview I click, probably pretty basic coding I want as simple solution as possible.
If possible I'm also looking for a solution that includes an SQLite database that stores the URL of an image and then display it in a single activity, also depending on which item I press in my current listview.
(I hope you understand my needs, and if you need I can also post my current code for the Menu class if it helps you help me) Or you can just show me a different way to make this work, I appreciate every answer! Thanks in advance!
NOTE
And please keep in mind, I'm a noob at Java and Android so keep it rather simple or at least explain what you do.
When you click on a list item, display the image in another view in the same layout, unless you want the image to take up the entire screen real estate. If you want it in the entire screen, go to a new Activity by sending the activity an Intent.
Activities are the "controller" of your application. They interact with the visible UI and the input from the user. You don't need a separate activity for each image, just an activity that's associated with a "place" in the UI (an ImageView) where you'll display the image.
I'd start by adding the images as resources under res/drawable before going on to databases.
You are going to have to do most of this yourself. There really isn't any substitute for taking the time to learn Java and Android. There are several tutorials and Android University classes under the Resources tab in the Developers Guide; I suggest you do all of them.
i'm making an app that requires indefinite textviews and images. i'm trying to implement a Pulse News app UI but having a hard time implementing one. so i thought of an idea to make a UI like that with the use of textviews, imageview and horizontal scroll view.
textview string values are from parsed xml online and images or the imageviews will be images from a specific directory in the sdcard that my app is using.
can anyone give me ideas how can i do it without using an xml layout or is there any or other options or ways for doing this? thanks...
You can create a viewgroup with one textview and an image. Then it can be added dynamically to your layout many times. This can be done by creating objects in a loop. You can change the content in each viewgroup at the time of inflation.
though i dont know what exactly how pulse new app looks like, but by going through your question (horizontal scroll view in particular) I guess you want to implement a "Gallery" type implementation where in you can swipe left/right on page basis.
If my assumption is correct then you will like to see to ViewPager of android backward compatiblity pkg.
