We encountered a problem when using SGIP to develop the unicom sp text message. When we send a marketing text message, the user not only receives this text message, but also receives an additional text message, the content is probably about who sent this text message and what is the billing method. Originally, our sp messages were free of charge, but users were confused as soon as they saw the "Tariff". A

(1) Concepts Dip: Device Independent pixels (device independent pixel ). different devices have different display effects, which are related to the hardware of the device. We recommend that you use this function to support WVGA, hvga, and qvga without pixels. Px: pixels (pixels). Different devices have the same display effect. Generally, we use hvga to represent 320x480 pixels, which is usually used. PT: point, a standard unit of length, 1pt = 1/72 inch, used in the printing industry, v

Size Units (px, dpi, dp, dip, and sp) of the View for android Application Development, and androiddpi I. pixel (px) and screen resolution 1) px (Pixels, Pixels): corresponds to the actual Pixels on the screen. For example, 320*480 screens have 320 pixels horizontally and 480 pixels vertically. 2) the screen resolution is the total number of physical pixels displayed on the screen. It is equal to the number of pixels x height on the screen width. In th

Currently, a poor android application is charging fees. A large number of developers rely on built-in ad clicks and application promotion and download revenues are meager. Because Apple has such a platform, Apple developers have a lot of revenue. This section describes the SP billing method in Android, which provides you with an option to make money. SP billing is a billing method that directly deducts th

DP (DIP): device independent pixels (unit independent pixels). Different devices have different display effects, this is related to the device hardware, generally we support WVGA, HVGA and QVGA recommend this, do not rely on pixels.DP is also a dip, which is basically similar to SP.You can use a DP or SP if you set properties that represent length, height, and so on. However, if you set the font, you need to use the

compared to the difference is more obvious. Dip 　　Exactly the same as DP, except the name is different. The dip was used in earlier versions of Android, and the DP name was later recommended for unification with SP. Sp Abstract pixels independent of scale (Scale-independent Pixel). The SP and DP are similar but the only difference is

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

Dip: device independent pixels, which is a density-independent pixel. It is an abstract unit based on screen density. On a display at 160 o'clock per inch, 1dp = 1px, that is, the 1: 1 relationship.

Difference between dip, dp, sp, pt and px in Android, androiddip 1. Overview In the past, programmers often designed computer user interfaces in pixels. For example, the image size is 80x32 pixels. The problem with this processing is that if you run the program on a new display with a dot (dpi) higher per inch, the user interface will look small. In some cases, the user interface may be small to difficult to see the content. Therefore, we can solve th
