字体大小基于dpi，android

Question

This seems to be a basic question, but I am not able to figure it out. I am creating an app which will run on ldpi, mdpi, hdpi, xhdpi, xxhdpi. I have a phone which is hdpi. Now font sizes are best judged when seen on a physical phone/tablet.

So say If it looks good on 18 pixel font on hdpi, on what sizes would it look good on others. Any ideas, best known good practices?

Thanks

Answer 1

Maybe this will help. Try using setTextSize(TypedValue.COMPLEX_UNIT_DIP, 18); in Java code

Answer 2

Try using sp as the unit of the fontsize. an 18px font should be 9sp on an hdpi device, and the os automatically scales it based on the density.

Answer 3

尝试使用setTextSize(TypedValue.COMPLEX_UNIT_DIP, 18);

Answer 4

尝试这个

setTextSize(TypedValue.COMPLEX_UNIT_DIP, 18);
