I find %~dp0 very useful, and i use it a lot to make my batch files more portable But the label itself seems very cryptic to me.what is the ~ doing Does dp mean drive and path This will not calculate the correct value for dp/px on many devices (including your nexus 10) As you say displaymetrics.density is rounded to the nearest screen bucket, but so is the dp unit! I am not asking what is the difference between dp,sp and px
I am designing a website based on google's new material design, all the measurements are in dp (for grid) and sp(for text) It focuses on teaching you how to develop a dp solution incrementally You will realize learning recursion (which is hard) is the stepping stone to solving dp questions (remember recurrent relation!) Try learning the problem patterns and recursion Dp would become easy eventually, it takes time though Android and setting width and height programmatically in dp units asked 14 years, 9 months ago modified 2 years, 9 months ago viewed 231k times
For android, people recommend using dp (density independent pixels) measurements for ui elements, and there are conventions that exist such as using 48dp for a button height, etc 目前视频DP接口最新版本1.4，HDMI最新版本2.1，均只支持最高到4K120Hz的视频信号。 那些4K144Hz甚至更高刷新率的显示器是怎么实现的?
