Displaying integer on toast

Question

Im trying to display a toast message with integer inside it This is how i tried to do it:

 Toast.makeText(this,bignum,Toast.LENGTH_LONG).show();

But it keeps crash my app. Thanks for help!

Solution 1

Toast.makeText either takes a CharSequence or an int as its second argument.

However, the int represents a resource ID (such as R.string.hello_world).

The application crashes probably because no resource is found with that ID, since it's not an ID to start with, but an arbitrary integer.

In your case, use Toast.makeText(this,String.valueOf(bignum),Toast.LENGTH_LONG).show();.

Solution 2

you need a String

Toast.makeText(this, String.valueOf(bignum),Toast.LENGTH_LONG).show();

otherwise android will try to look it up for a String with id bignum, in your strings.xml file

Solution 3

Try this to "cast" bignum to string:

Toast.makeText(this,"" + bignum,Toast.LENGTH_LONG).show();

"Crashes my app" tells us nothing. What exactly happens? What errors are logged? What happened when you debugged?

Even on your second day, we expect you to be able to report what error messages you saw.

@GalIsrael It was just a joke. :) Putting Integers on toast, like baked bread. That's all. Wasn't a criticism.
