I am attempting to populate textview with information from objects. I am new to android development and I do not know how to approach this. Hard Coding this in the xml will not work because eventually I would like to open up the same activity but with different information.
I do not know if this is enough information but thank you for responding and if code is needed I would be more than willing to upload code or screen shots.
textview.setText(user.getName());
Refer this

I'm trying to make an app and I have made a blueprint for a specific activity, but I don't know how to implement it. The layout contains few buttons at the top of the activity, and each button features some information, which is displayed inside the view. The view which needs to be updated is present under the buttons. I don't want the activity to be changed, instead it should update the contents of the View, which is different for each category/button.
By doing some research I have realised that the "Tab Layout" can be used to achieve my requirements, but I don't want the tabs and I need some stylish buttons as a replacement.
I know I'm not the best at describing, so I have looked upon Dribble and found one design which is 100% similar to blueprint.
I want to achieve this using XML and Java using Android Studio! Every suggestion will be a great support foy my app.
Thanks a lot.
As far as I know, you could achieve that by using fragments (which is the same concept you would have used on TabLayout). I don't really know how much knowleadge you have on Android, but if you know what a Fragment is, it should be easy for you to recreate the idea.
You have 3 buttons for 3 different fragments, so you must design every fragment by separate and change it depending the button you click.
I would like to know what the Android implementation is of this type of scrolling that you see in the Yahoo Weather App. Here is a video example:

Any examples or ideas on how to implement this would sincerely help this poor lost soul!
Thank you
use that library https://github.com/xgc1986/ParallaxPagerLibrary, it's very easy to use, and it worked for me
demo
You should separate two different things here:
The horizontal scrolling
As you swipe your way through the viewpager, the background moves slower than the content does.
This effect can be achieved with the ParallaxPagerLibrary
The vertical scrolling
As you swipe up, the background image blurs away, making the "swiped up" content more visible to the user. This post explains it all and also provides a library.
But if you want it even better, someone wrote a simple "clone" of this weather app https://github.com/MoshDev/LikeYahooWeather
They customized ViewPager, the widget is called WeatherViewPager that it's unfortunately unavailable, looks like a ViewPager with a sort of parallax
You may take a look at https://play.google.com/store/apps/details?id=com.desarrollodroide.repos
it's a collection of usable opensource libraries
e.g. Utils->Paralloid or Utils->ParallaxScroll
I'm trying to show some information about the currently casted media inside the cast menu like this. The example apps provided by Google are using the CastCompanionLibrary, which won't be available in my project.
There isn't any hint in the Development Guide, so I really hope that there is anybody out there who knows how to do this.
Thanks in advance!
You need to write your own MediaRouteDialogFactory which needs your MediaRouteControllerDialogFragment which needs your MediaRouteControllerDialog.
Then use it via [Cast Icon] or [action bar menu item].setDialogFactory(yourMediaRouteDialogFactory).
Best to take a look at the Video Sample App.
Is the question about how to get info, or you are also asking about how to show a custom dialog when a cast icon is clicked on *while casting)? As for information, the image you referred to currently shows (a) some metadata about the media that is playing there (icon, title, ..) and (b) the playback status (paused/playing). These info are available from RemoteMediaPlayer.getMediaInfo() and getMediaStatus(). You should also register the dialog to listen to updates to media status and metadata so when the dialog is open, it can reflect the changes.
CCL is just a wrapper around the SDK apis so you can look at its code to see how it is using the SDK apis to accomplish these tasks.
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 got a problem in Android application, I don't know how to make the selected pins on top of overlaaped pins.
In objective-c, iPhone we use the below methods But, I don't know how it can be implemented in Android phone, java.
[annotationView.superview bringSubviewToFront:annotationView];
[annotationView.superview sendSubviewToBack:annotationView];
Please suggest any solution,
Thank you,

You want a statelist drawable. http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList
