Project description

In this project I want to show how to use Toasts and Notifications to communicate with a user.

Requirements:

  • There are four buttons: Make basic notification, Make custom notification, Make toast oraz Make custom toast.
  • Depending on the type of button we have pressed a correct notification of Notification or Toast type should be displayed.
  • custom methods should display our own custom notifications.
  • Every time Make notification is pressed, text displayed by this notification should be modified.

All the information needed to complete this project can be found in Materials section.


How it should work

My application is an extended version of what should be done to show three other Notification style (beside standard known as Basic and custom under the Custom name):

  • InboxStyle - allows to display message in max. 6 rows.
  • BigTextStyle - allows to display on big block of text.
  • BigPictureStyle - allows to display image and text.

Source code
