AndroidTwo smart pointer types are defined, one is strong pointer Sp (Strong pointer), The other is the weak pointer (Weak pointer). In fact, it is more suitable for strong references and weak references. Strong pointers share the same concept as smart pointers in general sense. The reference count is used to record how many users are using an object. If all users give up referencing this object, the object will be automatically destroyed. The weak

just a measure of the pixel density. Third, DPIndependent of the physical density of the unit of measurement, it is based on 160dpi , regardless of the DPI screen, 1DP represents the same physical length. In the 160dpi screen, 1DP=1px, that is, a DP needs to be represented by an PX , on the 240dpi screen, 1DP=1.5px, indicating a DP needs 1.5 px to indicate. That is to say 1DP=dpi/160*px. The implication is that developers will be able to develop a UI that displays the same size, regardless of t

Differences between Android px, dp, and sp Since the rise of Android, developers have been increasing, while devices on the market are also increasing. What follows is the troubles and complaints that developers need to adapt to a large number of models. With the customization of different ROM devices from different manufacturers, the fragmentation of Android devices is becoming increasingly serious.

Recently, I've seen a lot of blog posts about conversion between DP-PX,PX-DP,SP-PX,PX-SP, and the way I used to do it was:1//Conversion dip for PX 2 public static int Convertdiporpx (context context, int dip) { 3 float scale = CONTEXT.GETRESOURC Es (). Getdisplaymetrics (). density; 4 return (int) (Dip*scale + 0.5f* (dip>=0?1:-1)); 5} 6 7//convert PX to dip 8 public static int Convertpxordip

SP and px conversion Formula : sp*ppi/160 = px conclusion: px = dp*ppi/16
