如何为 Paint.setTextSize() 设置单位 [英] How to set unit for Paint.setTextSize()

问题描述

是否可以更改Paint.setTextSize() 的单位?据我所知，它是像素，但我喜欢在 DIP 中设置文本大小以支持多屏幕.

Is it possible to change the unit for Paint.setTextSize()? As far as I know, it's pixel but I like to set the text size in DIP for multiple screen support.

推荐答案

这样转换

// The gesture threshold expressed in dip
private static final float GESTURE_THRESHOLD_DIP = 16.0f;

// Convert the dips to pixels
final float scale = getContext().getResources().getDisplayMetrics().density;
mGestureThreshold = (int) (GESTURE_THRESHOLD_DIP * scale + 0.5f);

// Use mGestureThreshold as a distance in pixels
