Question

I need to display 4 “Toast”s spaced by 2 seconds between them.

How do I do this in such a way that they wait for each other and that the program itself waits until the last of them has displayed?

Answer 1

simply use handlers.

handler has a method called sendMessageDelayed(Message msg, long delayMillis).

just schedule your messages at the interval of 2 seconds.

here is a sample code.

    int i=1;
    while(i<5){

    Message msg=Message.obtain();
    msg.what=0;
    hm.sendMessageDealayed(msg, i*2);
i++;
    }

now this code will call handler’s method handleMessage after every 2 seconds.

here is your Handler

Handler hm = new Handler(){

public void handleMessage(Message msg)
{
//Toast code.
}
};

and you are done.

Thanks.
