Class Madness

ARE YOU READY TO MAKE MOAR CLASSES?! [classes, android 101]

Recommendation: Create two projects at once so you practice each set of skills back to back. This will help you memorize the steps you need to take for future use.

Let's Practice Making Classes

  • You will create two Android projects for this exercise. One will be called Haunted House and the other will be Paradise.
  • For each of these projects, you will create a Java class (HauntedHouse and ParadiseLocale).
  • Each class must have 4+ member variables declared as private (mMyVar).
  • Each class must have two constructors:
    • one that accepts 0 arguments (such as new HauntedHouse())
    • one that accepts 5 arguments (such as new ParadiseLocal(String name, Double lat, ...))
    • Both constructors must set values to the member variables of your class.
  • Create Getters and Setters* for at least two member variables in each class.

Let's Put our classes to use in an Activity!

Test line by line... always debug

  • Now that you've created your classes, it is time to include it in your activity after setContentView.
  • Add a TextView and a Button to your layouts for both applications. Make sure to give them ids.
  • Inside of your MainActivity classes, create member variables or them.
  • In your onCreate method, assign values for your TextView and Button member variables using casting and findViewById()
  • Create an OnClickListener using new View.OnClickListener() { ... /* override etc */ }
  • Assign the OnClickListener to your Buttons.
  • Create a new private member variable for your MainActivity: one for each class in each corresponding project (HauntedHouse mHauntedHouse;
  • Inside of onCreate, instantiate a new copy of your class using the constructor of your choice by assigning the new instance to your member variable (mHauntedHouse).
  • Inside the OnCLickListener, setText() on your TextView member variable to display data from your class.
