I'm looking for a simple example of how to display data on a screen in the same way the Guardian app does (including the image on the left) that I'm pulling from a php page as shown in the screen shot below. I just can't find any examples on the internet that fit this description.

Sorry for what might seem like a simple question :)
I think these should help.
On stackoverflow, amongst others:
SO - ListView and images, which also links to SO - Lazy loading of images in ListView
External:

I am working on an android app that will be used to learn few technologies from tutorials. Each tutorial will contain several images distributed across the text. Same as like the tutorials we read on websites.
What logic I should use to implement this. The text and images will be fetched from local database.
Check these links for ImageView and TextView in android.To have images in between you need to properly place imageviews between textviews. If you want to add images dynamically and if you are not sure about the number of images you are going to add, build your layout in Activity(or Fragment) class not using xml.
Make html pages out of them and use a WebView to display the html.
This is not a question on how to load the data. I have already loaded the data and it works fine. The issue that I am trying to solve is when ever i go to that page / view it seems to show a black screen before showing the data on the screen. which I can solve by putting a spinner on the screen. But my question is how does app like gmail loads all its information on the listview so quickly. I tried using the CursorAdapters but it still takes few second before the screen is populated with the data. The screen only has images and text. at most it loads like 20 data in the list. Can some one please help.
Thanks in advance.
Here is a screen shot of what is displayed on the screen.
Well you are loading heavy data(images not just raw strings). I know its not answer you wanted but im not sure what could you do. Putting it on some background service might help. Again not sure about solution.
I am looking to implement lazy loading in my app and I cannot seem to get it done. I've looked everywhere and nothing seems to be working.
My app is a news app making a SQL query to my wordpress website and getting the image URL and the article title associated to the image. The thing is I cannot use list views for this app because I want the first article to be a way bigger image that takes a third of the screen and the title placed on the image (the same way it is done in this image : http://iphone-apple.fr/wp-content/uploads/2010/06/lequipe2-iphone.jpg).
To create the design I have used RelativeLayout. Each article is a RelativeLayout composed of an ImageView and a TextView.
My problem is that all of the tutorials I found on lazy loading for ImageViews on the internet are for ListViews.
I have tried AsyncTask but it did not work. It actually worked but it showed all of the images at the end of the load so I had a black screen for about 5-10 secs before showing the main activity.
Does anyone have any idea how I could proceed ?
Thanks a lot for all of your answers ! :)

I am working on Android. I kept images in GridView. Now when I click on any image that image should display in seperate screen and from there the remaining images should also open while swiping. How can I achieve that task? Please help me in this regard.
Use a ViewPager.
The official tutorial is here: Using ViewPager for Screen Slides
Since you didn't actually explained so there can be no specific answer and here is a links you might use
1-using PageAdapter
or you can use GestureDetector witch you can search in here
hope it would be helpful .
I have a database full of item witout images. i'd like to show an image when the user watches the detail of an item. My idea was to search an image on google, take the first result and then include it in the activity.
Can this be done with android? and if so, what's the best (or maybe the easyest) practice?
I think you can use https://developers.google.com/custom-search/v1/overview to search images
