以编程方式将LayoutParams上的高度设置为与密度无关的像素 [英] Programmatically set height on LayoutParams as density-independent pixels

问题描述

是否可以通过任何方式设置 LayoutParams 作为与密度无关的像素(dp)?以编程方式设置的高度/宽度看起来是像素而不是dp.

Is there any way to set the height/width of a LayoutParams as density-independent pixels (dp)? It looks like the height/width, when set programmatically, are in pixels and not dp.

推荐答案

您需要将dip值转换为像素:

You need to convert your dip value into pixels:

int height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, <HEIGHT>, getResources().getDisplayMetrics());

对我来说，这就是窍门.

For me this does the trick.
