Answer:

Null layout manager enables UI components to be placed at specified coordinates (x and y values).

Explanation:

Null layout is generally used by developers while creating demo UI or prototypes since the component location can be precisely specified in terms of x,y coordinates. This is also called absolute positioning.

However null layout suffers from a number of problems due to which it is normally avoided in production scenarios:

  • Hardcoded coordinates and sizes are not portable across different environments ( different screen sizes,resolutions and font sizes).
  • Null layout does not support preferred sizes for components.  Component size cannot change with environment.
  • User interface with null layout does not readjust automatically when the top level container is resized.

Which of these sites would need additional investigation to check for reliability?
irga5000 [103]
Could you please give add some detail? I would assume any site ending in .com would need to be checked for reliability due to the fact anyone can have a .com, but a site such as edu is more trustworthy.
