纵观Android的教程，如记事本教程，我注意到，几乎所有变量命名开始以字母M。什么约定是这一点，并在它的起源？

Looking at the Android tutorials such as the Notepad tutorial, I noticed that almost all variables are named starting with the letter 'm'. What convention is this, and where does it originate from?

推荐答案

它代表成员。我个人觉得这个惯例无益的，但它是主观的。

It stands for member. I personally find this convention unhelpful, but it's subjective.
