There is an Activity with ImageButton whose dimensions are 100dp per 100dp. For screens with a diagonal of 7 inches, this button will have a size of 200 by 200, and on screens with a diagonal of 10 inches 300 by 300. Can you please tell the background image to be clearly displayed on all these screens, what size should the picture be for each of these screens? And what resolution is 300 or 72 enough?

  • Tell someone? - Genius
  • What do you understand by the word "clearly"? - pavlofff
  • That the picture was well displayed - Genius
  • I made the following picture sizes: 100,150,200,300 and 400. But the buttons decided to make sizes 100 × 100, 150 × 150 and 200 × 200, respectively - Genius
  • It remains to understand the background. I don’t understand yet what sizes the background image is usually made for the application itself - Genius
