out what PPI means, we can easily understand how the PPI works, we need to figure out the diagonal equivalent of the cell phone screen, and then we'll get the PPI by going diagonally (the length of the phone screen that we normally call the screen size). Accurate calculation of publicity you can refer to the following figure. Interestingly, the 4 PPI for the IPhone, calculated on the formula, is 330 higher than the official 326 of Apple's announcement. Similarly, in HTC G7, for example, the

There is a gap between the UI layout and the original resource size.

with a little bit of knowledge about the camera. Camera trivia RGB565 and YUV422 1. What is RGB565 is known, RGB is composed of three colors of color, to display a pixel color, each pixel needs 3 byte data of R, G, B to represent, that a pair of 320* 240 of color images, you need to 320*240*3=230400b=225kb the data to store, so it appears that the space cost of storing images is enormous. In a pixel RGB

queried, its DPI is 240, so calculate the height should be:197.53/(240/160) =131.68 (DIP), approximately equal to 132DP, so we set the height of the above ImageView to 132DP: Let's take a look at the display effect:This shows that the scale is perfectly normal.But does that solve the problem? The answer is no, we might as well change a simulator to show, this time choose NEXUS7 Simulator, the resolution is 1200*1920,dpi for 320,imageview parameter

is related to the device hardware, generally we support WVGA, HVGA and QVGA recommend this, do not rely on pixels. SP (scale independent pixels): Similar to DP, but can be scaled based on the user's font size preference.scaled pixels (enlarge pixels). Mainly used for font display of best for textsize. In order for the user interface to display properly on the current and future display types, it is recommended that you always use the SP as the text size unit, and the Android default fo

Click the second button at the bottom right, select width and height (when creating is 320*480, now to fit 320*568), 44 ((568-480)/2), click Add 3

WebApp Meta tags and webappmeta tags 1. First, let's talk about the viewport In the mate Tag: Viewport is the visible area. For a desktop browser, viewport is the area used to view webpages after all the toolbar, Status Bar, and scroll bar are removed. For traditional WEB pages, the 980 width display on the iphone is normal and full screen, but it may be a problem for webapps, on the iphone, our webapp is usually 320 in width under the portrait screen

Due to the importance of multimedia services, the softswitch system initially considered support for multimedia business applications from several main aspects. First, in terms of the network structure, the processing and calling of multimedia applications are separated, and the unique information processing functions of multimedia services are implemented in media servers and smart terminal devices, general call control and service provision are completed in softswitch devices and application s

First, mobile device picture blur problemCell phone blur The problem is the difference in the actual pixels that a pixel represents on the computer and on the phone.The PX (independent pixel) units we use in the stylesheet do not necessarily represent the actual one pixel (physical pixel), which depends on the hardware settings. For example, a stolen image below, a separate pixel on the right is equal to four pixels, and a separate pixel on the left is equal to one pixel. Devicepixelratio is the
