如何找到Material Design UI元素的尺寸？

Question

When trying to pick padding and width and margin for UI elements, I see that some default values pop up in the XML. This makes me think --> Is there a standard set of measurements that I can use for material design instead of trying to guess what looks right?

Like in the picture below, where specifically in the documentation can i find the list of all dimensions available?

Answer 1

Android specifies certain widths and heights that you should use for your application. For example the horizontal and vertical activity margins, the padding in TextView or EditText . See https://material.google.com/layout/metrics-keylines.html for the guidelines.
