一个LinearLayout中的边距，编程方式与DP [英] Margins of a LinearLayout, programmatically with dp

问题描述

是否有可能设置的LinearLayout的边缘，编程而与像素，但DP？

Is it possible to set the Margins of a LinearLayout, programmatically but not with pixels, but dp?

推荐答案

您可以使用<一个href="http://developer.android.com/intl/de/reference/android/util/DisplayMetrics.html">DisplayMetrics并确定屏幕像素密度。事情是这样的：

You can use DisplayMetrics and determine the screen density. Something like this:

int dpValue = 5; // margin in dips
float d = context.getResources().getDisplayMetrics().density;
int margin = (int)(dpValue * d); // margin in pixels

我记得最好使用地板的偏移量和取整的宽度。

As I remember it's better to use flooring for offsets and rounding for widths.
