Android in Dip, DP, PX, SP and screen density 1. Dip:device independent pixels (device independent pixels). Different devices have different display effects, this is related to the device hardware, generally we support WVGA, HVGA and QVGA recommended use this, do not rely on pixels.It is important to note that dip is related to screen density and that the screen density is related to specific hardware and that the hardware settings are incorrect and m

First refbase in the C + + part of Android is as a base class for all classes, which functions like an object in Java. A private member exists in this class:weakref_impl* const mrefs;(Weakref_impl is a subclass of Weakref_type)This mrefs is a "shadow object" and is the key to managing the reference count of an objectRefbase is constructed in Mrefs (new Weakref_impl (This)), new is a Weakref_impl object, Weakref_impl's constructor parameter is Refbase's pointer and initializes the WEAKREF_IMPLMst

What do designers and developers agree on to develop an android APP?First, choose a mainstream model.Then, the designer based on the screen size of the model design, give the PX unit labeling.Finally, according to the model, we can calculate the conversion method of PX and DP, and set the dimension of DP unit according to the dimensions of PX unit.Note: 1DP=1DIP=1SP, for the general long-width DP or dip can be,

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

Add SP value-added services in PHP. now, you need to add SP value-added services to a website, including user registration, sending verification text message codes, completing registration, and sending member identity verification long codes, I have not yet received the mobile port and protocol yet. I want to prepare the protocol in advance. please advise me how to prepare the protocol. I also heard that PH

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

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 that the Android system

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, how many pixels per inch There is a member with the same name in the android api. The method is as follows: 2. dpi indicates the pixel density of t

Dip: Device Independent pixels (device independent pixels). Different devices have different display effects. This is related to the device hardware. Generally, to support WVGA, hvga, and qvgaWe recommend that you use this,Pixel independent.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, very easy to use;

If something is wrong, I still hope to correct it.

Px: The pixel of the screen.In: inchesMM: mmPT: LB, 1/72 inchDP: an abstract unit based on density. If a screen of DPI is displayed, 1dp = 1px.Dip: equivalent to DPSP: similar to DP, but it also scales according to the user's font size preference.We recommend that you use SP as the unit of text, and dip for others. The following is an overview of the relationship between DIP and PX: The following figure shows the resolution information density, which
