This is an android tutorial about the Toast class, how to use it to show short messages and various libraries that allow us to customize or create new unique Toasts.Ī toast provides simple feedback about an operation in a small popup.

Here’s what that looks like when it’s loaded.Android Toast Tutorial, Examples and Best Open source Third party libaries. By putting this inside an else clause, we’re basically letting the program know that if hint_counter is anything other than 0, it should run that block of code.Īnd that’s it. That semicolon is important, so don’t forget it.Īfter that, we’ll set up the second condition, showing the other toast message. Once that first condition has run, we’ll increment hint_counter up by one. To make things simple, I’m hardcoding the text here in the java file, but you could also stash the hint inside the strings.xml file and refer to it as R.strings.whatever_you_called_the_hint. This will go inside the showToast method that we created last week.

That way, if the variable is 0, the app will know use the code within the first condition, and once it gets higher, it’ll go to the second. Since we’ll be using it in our conditional statements, it’ll need to be an integer (or int).Īnd we’ll set it to 0 to start. Like a method, you’ll start off with visibility. We’re going to grab the = for ” is equal to” and use a hint_counter variable to tell Android if the button has already been hit.ĭeclaring a variable in java is pretty straightforward. Some of the simplest you can use are these: Math is evil, but luckily, this is only going to require a really simple equation.

If a user hits the Hint button once, a toast message will pop out reading, “It has no fingers or toes either.” Otherwise, the toast will say, “And lives all over the world.”Ĭonditions can be formatted in a lot of different ways. To keep the mystery alive, we’re going to keep hints semi-living creatures related. Quick reminder, our test riddle was “What has a neck but no head?” Most people start guessing insects for that one ( isn’t an earthworm basically all neck? you might argue), but the answer we’re looking for is “A Bottle.” Going back to this Riddler App, I want to add hints for the user if they can’t guess the answer outright. Today, we’re going to make it a tad more dynamic with an if/else statement. Last week we covered how toast happens in Android Studio.
