What is Android Toast?
- A toast provides simple feedback about an operation in a small popup. It only fills the amount of space required for the message and the current activity remains visible and interactive.
- For example, navigating away from an email before you send it triggers a "Draft saved" toast to let you know that you can continue editing later.
- Toasts automatically disappear after a timeout.
- Toast is a solution for android developer when required to notify user about an operation without expecting any user input.
- This provides a small popup that displays for a small period and fades out automatically after timeout. Sometimes developers use this for debugging.
- In Android, Toast is a notification message that pop up, display a certain amount of time, and automatically fades in and out, most people just use it for debugging purpose.
Code snippets to create a Toast message :
//display in short period of time
Toast.makeText(getApplicationContext(), "msg msg", Toast.LENGTH_SHORT).show();
//display in long period of time
Toast.makeText(getApplicationContext(), "msg msg", Toast.LENGTH_LONG).show();
