: 1x16=16px=1rem; the browser defaults to 16px may cause the REM computation of trouble and many decimal places, so we can also do this way to initialize the root element:html{ font-size=62.5%//This is 10/16x100%=62.5% is the default 10px font size}After this initialization, we are going to have a lot less hassle when it comes to REM computing.2.

The following is a summary of the above three commands: 　 Command Format Parameters Restrictions Response Example User Name Specifies the mailbox string, which is critical to the server Only when the user and PASS commands fail or are in the "OK" status + OK: valid email address;-Err: invalid email address C: User mroseS: + OK mrose i

Today I have made a good research on the speech compression encoding in Android, and I have some tips: First of all on the collection of sound source format is the PCM-16bit format, What Is PCM format, you can see the following article: Http://blog.csdn.net/tkboy/archive/2009/12/19/5038947.aspx PCM is a non-compressed sound source. PCM signals are digital signals composed of [1], [0], and other symbols. This format is used by Android devices, we also perform compression encoding for this form

displaying the content on the screen. The Display memory is actually one or several large-scale integrated circuits installed on the display card. Its capacity is 1 m, 2 m, 4 m, 8 m, etc, in dos, the memory that we can access is only 1 MB (this is the limitation of DoS). The address ranges from H to fffffh. The memory is divided into different blocks based on the purpose, the address allocated by the system to the graphic buffer (Display memory) is between a0000h and bffffh, And the size is KB.

and height of the View. Now we can see the difference between dp and percentage, and the percentage can better solve our adaptation problem. Some tips adaptation Let's take a look at some matching tips. In fact, the above three tip points are used in the final analysis. match_parent is equivalent to 100% reference parent control; weight is allocated proportionally; custom view is nothing more than because most of the size is calculated by percentage; Through these tips, we can see that if we

generailized size/density. In actual Layout design, the Unit should be dp, which can avoid the impact caused by different screen dpi. The most typical example is Apple's retina screen. Xlarge: at least 960dp x 720dp Large: at least 640dp x 480dp Normal: at least 470dp x 320dp Small: at least between DP x 320dp Px = dp * (dpi/160) For example, for a 1.5 DPI screen, 1dp is equivalent to pixels. Px, dpi, dp, dip, sp Measurement Unit Explanation Px (pixel)

Tags: Android HTTP Io ar OS use for SP strong Px, DP, dip, SP, In, mm, PT detailed analysis Px :( pixels): the pixels on the screen. Different devices have the same display effect. Generally, we use hvga to represent 320x480 pixels, which is usually used. Dip: (device independent pixels), device independent pixels. This is related to the hardware of the device. We recommend that you use this method to support wcga, hvga, and qvga, instead of pixels. Equivalent to DP. DP: an abstract unit

" (vertical screen), the camera preview will appear left-leaning 90 degrees phenomenon, and loss ratio. The reason for this (I suspect) is that the camera control map is fixed by the Android bottom, is landscape, and produces a 320*480-like image, and if replaced by portrait, the camera still produces a 320*480 image, Then the corresponding to put into a 480*320
