Displaying same font size in any Android screen

Question

I want a text to have relatively same size in every Android device.

I have a canvas (fullscreen). In middle of this canvas is some text. This text fills 20% of my screen leaving 40% for both sides. I want these precentages to be true when text is viewed in any Android device.

I also want the same thing vertically.

Answer 1

使用“ sp”单位将尺寸放入Dimension资源中 。

Answer 2

I decided to measure width of text in pixels and save that value.

When text is loaded in different resolution, I multiply the original pixels with scale of resolution change. I loop up from text size one, always calculating new resolution and checking which matches the original resolution best.
