I am studying the use of Threads, aSynkTasks and Handlers and I came across this method, runOnUiThread ()
How does this method become a repetitive process to the point of replacing the handler? does this method work?
I would like to understand how this method works and what need to implement Runnable () within this method as in this example:
runOnUiThread(new Runnable())
public void run(){
// alguma coisa}
Method definition:
"Performs the action specified in the UI Thread. If the current Thread is the Thread of the UI, then the action will be executed immediately. If the Thread current is not from the UI, the action is thrown in the event queue. "
So let's go:
I believe it does not replace Handler because they have different features!
runOnUiThread , sends a Runnable to run on the UI Thread, while Handler , executes a Runnable at a future time (predefined) or executes this Runnable on a Thread different (not just UI as runOnUiThread ).
I believe the above definition explains its operation!
Now let's set the Runnable :
The Runnable interface should be implemented by any class whose instances are meant to be run by a Thread.
We use Runnable to encapsulate and send the code we want to transfer to run on another Thread .
