layout_width is shown here. Android: maxwidth: sets the maximum width of the text area. Android: minwidth: sets the minimum width of the text area. Attachment: length units in Android The length units in Android are detailed (DP, SP, PX, In, PT, mm). Many people do not quite understand the difference between DP, SP, and PX: here we will introduce DP and sp. DP is dip. This is basically similar to sp. You can use DP or SP to specify attributes such as length and height. If you set the font, you

//////////////////////////////////1. drawable -( Hdpi, Mdpi, ldpi) DPI is the abbreviation of "dot Per Inch". The number of dots per inch. Four density classifications: ldpi (low), mdpi (medium ),Hdpi(High), and xhdpi (extra high) Normal screen: ldpi is 120, mdpi is 160,HdpiIt is 240, and xhdpi is 320. 2. Differences between WVGA, hvga, and qvga VGA is "video graphics array", and the display standard is 640*480. WVGA (wide VGA) Resolution is 480*800

choose one C [3] [1] method. Dp [2] [3] + = dp [1] [1] * c [3] [2]; two keys are used in the second stage, open the three boxes in the second stage and select 2 C [3] [2] methods. Dp [2] [3] + = dp [1] [2] * c [3] [1]; two keys are used in the first stage, and one key is used in the second stage, open the three boxes in the second stage and select one C [3] [1] method. This is the end of the analysis. It is worth noting that the number of feasible methods should be divided by the total nu

Android screen adaptation principleOutline 1. The screen size corresponding to the folder under the res directory in android 2. The principle of representing the size with dp 3. What should I pay attention to when adapting to the P size 4? What size should I add to the ui cut chart? best reference: http://www.360doc.com/content/12/0301/17/5087210_190881395.shtmlConcepts:1) screen density (dpi): dot per inch, that is, the number of pixels per inch. Ldpi (120), mdpi (160), hdpi (240), and xhdpi (

still 3.2), the screen density is changed to 320. The original TextView width is set to 320 PX, And the 3.2-inch screen with a density of 160 is half shorter than the 3.2-inch screen with a density. But if it is set to 160dp or 160sp. The system automatically sets the width property value to 320px. That is, 160*320/160. Among them,

same resolution is 490. In this case, there will be many numbers in the screen density, showing serious fragmentation. The density is the basis for scaling and displaying the interface on the android screen. How does Android adapt to so many screens? In fact, each Android phone screen has an initial fixed density, which is 120, 160, 240, 320, or 480. We call it "system density ". Do you find the rule? There is a double relationship between values. In

Many netizens do not quite understand the difference between DP, SP, and PX: here we will introduce DP and sp. DP is dip. This is basically similar to sp. You can use DP or SP to specify attributes such as length and height. If you set the font, you need to use sp. DP is not related to density. SP is not only related to density, but also to scale. If the screen density is 160, DP and SP are the same as PX. 1dp = 1sp = 1px, but if PX is used as the unit, if the screen size remains unchanged (assu

The simple factory model and the factory method pattern have been described earlier, and the third plant model-Abstract Factory mode-is still being introduced, as is the case with the manufacture of automobiles. Example background:as customers become more demanding, BMW needs different configurations of air conditioning and engine accessories. So the factory started to produce air conditioners and engines to assemble cars. At this time the factory has two series of products: air conditioning and
