Hi Raul,
You could use the Toast.cancel() or Toast.setDuration() method to dismiss
the alert programatically.
To call Toast from a thread other than the main UI thread you can create a
handler in the main UI thread, and then post the runnable in which your
Toast is created to this handler.
final Handler mHandler = new Handler();
Thread t = new Thread() {
public void run() {
mHandler.post(mUpdate);
}
};
t.start();
}
final Runnable mUpdate = new Runnable() {
public void run() {
Toast.makeText(Spad6.this, "New message",
Toast.LENGTH_SHORT).show();
}
};
Thanks,
Megha
