I see Toast being simmilar to AlertDialog. Still it is not a solution for
me. The docs say the time the Toast is visible could be customizable. I
don't see how. Anyway, I still get to the Looper problem. The API demos
indicated make use of a Toast in the event thread. I need to show it in
another thread. eg:
public void run(){
// show information dialog 1
// try to do lengthly_stuff_1
// hide information dialog 1
// if lengthly_stuff_1 failed {
// show information dialog 2
// do lengthly_stuff_2
// hide information dialog 2
}
}
Writing this e-mail, I got the idea to show the alert or Toast in the event
thread ( runOnUIThread() ). It works and like this I can avoid the Looper.
Ok, but what can I use to hide / dispose it exactly when I want and to do
this programatically ?
regards,
Raul
