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

When developing applications using the ecmascript object model, we do not consciously want to know what methods a certain SP object provides? Here we will look at how to do it.1. Add a visual webpart (named wplkecmascript) and a Javascript file (named ecmaoplistitems. JS) to the SharePoint project we created earlier)The code for ecmaoplistitems. JS is as follows. This code is used in the previous introduction to extract website attributes.// Retrive w

1. OverviewIn 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 this problem by developing a program using a measurement unit unrelated to the resolution. Android Application De

When SharePoint client JS is developing, there are two ways to wait for a SharePoint object to load and then call its own method (MyFunction): executeordelayuntilscriptloaded (myFunction, "sp.js"); Sp. Sod. Executefunc (' sp.js ', ' sp. ClientContext ', myFunction); With which one?Jony's answer is: If the code is embedded in the publishing Page, with the 2nd, otherwise, you can use the 1th one.Ex

An in-depth understanding of the three registers of ARM is of great benefit to programming and porting the operating system. 1. Stack pointer R13 (SP): Each exception mode has its own R13, which usually points to the stack dedicated to the exception mode, that is to say, the five exception modes, non-exception modes (user mode and system mode) all have their own independent stacks and are indexed using different stack pointers. In this way, when the

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

Px, dp, sp, and androidpxdpsp used in android DevelopmentFirst, we will introduce these units: Px: pixels (pixels), which corresponds to the actual pixels on the screen. 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. (Dp is dip)Sp: scaled pixels (enlarged pi

different phones, you will find that some phones are shorter than the phone screen, some are longer than the screen, on the tablet and mobile phone compared to the difference is more obvious.DipExactly 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 bu

1. dip: Device Independent pixels (device independent pixel ). different devices have different display effects. This is related to the hardware of the device. We recommend that you use this function to support WVGA, hvga, and qvga without pixels. Note that the dip is related to the screen density, and the screen density is related to the specific hardware. Incorrect hardware settings may cause the dip to fail to be properly displayed. On a display with a screen density of 160, 1dip = 1px, somet

In the layout file of Android, a specific unit may be specified, for example, PX, dip, or sp. Their differences are as follows: 1. PX (pixels) pixels: a large number of pixels are used. Generally, hvga represents 320x480 pixels. 2. Dip or DP (device independent pixels) Independent pixels: This is related to the hardware of the device. We recommend this option to support WVGA, hvga, and qvga cwj, instead of pixels. 3.
