Android screen size and density table, and explanations of pixel units such as PX, dip, and SP

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 density. You can use this option to set the w

Android uses bitmap to get image pixel data _android

This article illustrates the way Android uses bitmap to get image pixel data. Share to everyone for your reference, specific as follows: The references on the Internet are: int[] pixels = new Int[bit.getwidth () *bit.getheight ()];//saves an array of all pixels, with a picture wide x high bit.getpixels (Pixels,0,bit.getwidth ( ), 0,0,bit.getwidth (), Bit.getheight ()); for (int i = 0; i Where the

When the distance between two centers is less than the radius of the collision.

Android development dip and pixel Conversion

Displaymetrics Class-A Structured description of a display's general information, including its size, density, and character scaling ratio. Public float density; // screen pixel density value. The density value indicates the number of display points per inch, which is different from the resolution. Android has the following screens: Qvga and wqvga screens density = 120; Hvga screen density = 160;

Android gets two ways to get the device screen wide and high pixel value

In the game we play we often see some of the effects of images, such as translucent and other effects. To achieve this translucent effect is not difficult, we need to understand the operation of image pixels.Don't be afraid, actually bitmap in Android gives us the basic way to manipulate pixels.We can get the pixel of the image through the Getpixels () method and put it in an array, and we can manipulate th
