How to learn 
App Inventor
A very interesting article I found recently is A guide to picking up new programming skills, Thank you Christian Rodriguez!
The single most important thing someone who wants to work in tech should learn is how to learn.
So what does this mean for people trying to learn App Inventor?
App InventorDo the tutorials to learn the basics of
App Inventor.
You will not find a tutorial, which does exactly what you are looking for. But doing the tutorials (not only reading a little bit) help you to understand, how things are working.
This is important and this is the first step to do.
You can find here at Pura Vida Apps more snippets,
tutorials and advanced examples.
Also Scott provides a large array of tutorials and examples.
Learn from the examples!.
There are also more helpful links to be found here.

This is part of the fun especially using App Inventor!

There is a great documentation and support library available,
which always should be consulted first in case of questions or problems.
Language Blocks Documentation
Components Documentation
Other topics, notes and details
In the Designer window you can get a short description for the components, just click onto the question mark.
And after clicking "More information" you will be forwarded to the corresponding page in the documentation.
In the Blocks window you can hover with the mouse over any block to get a short description of its use.
In case you are unsure, what's happening in your blocks, there is the Do it functionality, which can help you to find out, what's going on.
Just right-click onto a block and select Do it from the menu to get a Do it result in a comment window.
Note: you need a connection to a device or emulator for this to work.
See also Scott's tip How to use 'Do It' to view procedure results, event arguments and local variables.
Before posting, it's a good idea to search in the forums. Many others have likely run into problems similar to yours.
Doing a Search is very easy, just go to the MIT App Inventor Forum, enter a search topic in the Search box and click Search.
Nobody wants to be asked something that's just a search away.
Are you ready to answer the question What have you tried? Btw: Thank you Matt Gemmel for this great article!
