[Android] related concepts such as pix, dip, dip, and sp, androidpix 1. px (pixels) pixels-is a pixel, which is the actual pixel unit on the screen. Dip or dp (device independent pixels) device independent pixels, related to the device screen.Sp (scaled pixels-best for text size): similar to dp, it mainly deals with the font size. Dpi (dot per inch): screen pixel density. The number of pixels per inch density: density indicates the number of displa

I know the differences among px, dpi, dp, dip, sp, in, and pt, pxdpi Px: That is, pixels. 1px indicates a physical pixel on the screen; The unit of px is not recommended, because the actual size of the same px image may be different on different mobile phones. Dpi: The abbreviation of dot per inch is the number of dots per inch, also known as screen density. The larger the value, the clearer the screen.Suppose there is a mobile phone with a physical s

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

From the start of the Android program, I was told that the common sense 1. Length width of the value to use the DP as a unit into the Dimens.xml file 2. The value of the font size to use the SP as a unit, also into the Dimens.xml file Then, there is no then, as if the subtext is that, you remember to use on the line. One day, when we accidentally put the font into a DP, it can work, and the effect of the same as 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 (device independent pixel). Different devices have different display effects, this is related to the device hardware, we generally support the WVGA, HVGA and QVGA recommended to use this, do not rely on pixels. Px:pixels (Pixel). Different devices display the same effect, generally we hvga represent 320x480 pixels, this use more. Pt:point, is a standard length unit, 1pt=1/72 inches, used in the printing industry, is very simple and easy to use; sp:scaled pixels

I. Overview We often set the container length during page layout, but we are annoyed by which unit of length should be used. The following types of description areas are supported in Android. Px (pixels)-pixels: different devices have the same display effect. Generally, hvga represents 320x480 pixels, which is usually used. Dip (device independent pixels) -- device independent pixel: This is related to the device hardware. Generally, we recommend that you use this parameter to support wcga, hvga

There are a lot of SP and DP online in AndroidArticleI have talked about it all, but there is always a feeling that I am not doing anything. Now, let's talk about DP and sp. Let's talk about it.
