First, let's take a look at several concepts. Screen size The actual physical size is calculated based on the diagonal line of the screen. For example, iPhone 4 is a 3.5 inch screen, that is, its screen diagonal line is long. 1 inch is about 25.4mm. The size unit points mentioned later is equal to 1 inch of 1/72. For simplicity,

First, preliminary thinking Although the Android display adaptation of the scheme is a bit strange, initially it is not easy to understand immediately, but this program does have its own truth, the whole idea is clear, the plan is complete, no mishap The "screen density scaling mechanism" used by Android, which corresponds to the Web front end, is the "screen scale reduction mechanism"

How does the font size of Android adapt to different resolutions? Someone asked me today how to adapt the font size of mobile phones with different resolutions and sizes in the android system? In fact, the adaptation of fonts and images is a truth. I, The principle is as follows: Assume that the resolution is 320x240,4

Android has been widely sought after since its launch. Due to its open features, the market has emerged immediately. Different Versions of Android machines, different Android OS, and different OEMs, of course there will be a lot of inexplicable screen sizes. for this reason, I introduced in my previous article how to get the width and height of the

the size of the APK file:How to optimize the source file: Master good coding habits, reuse code, for some repetitive code logic reuse; Using Proguard to confuse code, optimize, compress (it's not just a cow rub obfuscation tool is also great in code optimization). By reducing references to useless code libraries, a common scenario is that some code libraries are not needed, but they are still referenced in the code, and the c

1. Set the text style (such as color and italic) in textview. You can set different styles for text in different positions.(For example, set the characters with an index range of 1-3 to black, and 2-6 to bold) Myfirsttextview = (textview) findviewbyid (R. Id. myfirsttextview ); Myfirsttextview. settext ("this is my first textview, ", buffertype. editable ); /** * Set the background color of the text, * The text must be set to buffertype. spannable and buffertype. ed

The screen size of Android mobile phones has always been a headache for developers. Because the screen sizes used by mobile phone manufacturers are different, the presentation and layout of user UI interfaces are naturally different. Therefore, when developing Android mobile appsProgramIn addition to understanding the underlying API, the most important thing is t

The concepts of PX, dip, SP, and DP are vague. I checked it online and found it clearly in theory. 1. PX (pixels): the point on the screen, which is related to the density. The density is high, and the PX size per unit area is large. 2. Dip or DP (pixels unrelated to density ). This is related to the hardware of the device. We recommend that you use this feature to support WVGA, hvga, and qvga 5 hexadecimal space. An abstract unit based on screen
