2. 1. Get the screen size of the current device
6. Displaymetrics displaymetrics = new Displaymetrics ();
8. This.getwindowmanager (). Getdefaultdisplay (). Getmetrics (Displaymetrics);
12. 2. Calculate the aspect ratio of the screen size set at the time of your development (this assumes that the screen size you set for development is 480*)
16. int screenwidth = Displaymetrics.widthpixels;
18. int screenheight = Displaymetrics.heightpixels;
20. float ratiowidth = (float) screenwidth/ 480;
22. float ratioheight = (float) screenheight/ 800;
26. RATIO = Math.min (Ratiowidth, ratioheight);
28. if (ratiowidth! = ratioheight) {
30. if (RATIO = = ratiowidth) {
32. Offset_left = 0;
34. Offset_top = Math.Round ((screenheight- RATIO)/ 2);
36. }Else {
38. Offset_left = Math.Round ((screenwidth- 480 * RATIO)/ 2);
40. Offset_top = 0;
42. }
44. }
48. 3. Determine the size of the font based on the minimum aspect ratio calculated in the previous step (assuming that the font size is set to on the 480* 800 screen)
52. Public static int text_size = Math.Round (* RATIO);
56. 4. Set the size of the font in the application based on the font size calculated in the previous step
60. Paint paint = new paint ();
62. Paint.settextsize (text_size);

1. Canvas.drawtext ("test", 0, 0, paint);
