How to use Variables in MIT App Inventor 2 [ With Example]
Показать описание
Variable, Creates a value that can be changed while an app is running, and gives that value a name. Variables are global in scope, which means you can refer to them from any code in the app, including from within procedures. When you create a new variable block, App Inventor chooses a unique name automatically.
Local Variable
A local variable is a variable that is declared within a function or it is an argument passed into a function. This means that you can only access these variables in that specific function where they are declared or passed in as an argument.
Local variables are created when:
arguments are passed in to a procedure or event
using the initialize local name to block
using a for each in list or for each from to block (these for loops will create a local variable for the letter.
Global Variable Example
Take out a get block and click the dropdown. There will be no variables to select. Create a global variable and name it count and initialize it to 0. Click on the dropdown of the get block. You can now see count available to choose. Once you have created a global variable, it will always be available in the dropdown of get .
