Toast

As we know that A toast is a view containing a quick little message for the user in android. When the view is shown to the user, appears as a floating view over the application.

Toast notification in android always appears near the bottom of the screen, centered horizontally.

We can also change its position with the setGravity(int, int, int) method.

This method has three parameters:

  1. A Gravity constant,
  2. An x-position offset,
  3. A y-position offset.
For instance:

TOP_RIGHT:
  1. Toast toast = Toast.makeText(getApplicationContext(), "TOP RIGHT!", Toast.LENGTH_LONG);
  2. // Here we can set the Gravity to Top and Right
  3. toast.setGravity(Gravity.TOP | Gravity.RIGHT, 100, 200);
  4. toast.show();
TOP_LEFT:
  1. Toast toast = Toast.makeText(getApplicationContext(), "TOP LEFT!", Toast.LENGTH_LONG);
  2. // Set the Gravity to Top and Left
  3. toast.setGravity(Gravity.TOP | Gravity.LEFT, 100, 200);
  4. toast.show();
BOTTOM_LEFT:
  1. Toast toast= Toast.makeText(getApplicationContext(), "BOTTOM LEFT!", Toast.LENGTH_LONG);
  2. // Set the Gravity to Bottom and Left
  3. toast.setGravity(Gravity.BOTTOM | Gravity.LEFT, 100, 200);
  4. toast.show();
BOTTOM_RIGHT:
  1. Toast toast = Toast.makeText(getApplicationContext(), "BOTTOM RIGHT!", Toast.LENGTH_LONG);
  2. // Set the Gravity to Bottom and Right
  3. toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT, 100, 200);
  4. toast.show();
