due to the introduction of AMD's RX 480 in the performance of eye-catching, much attention to the players. Nvidia has also been forced to launch the GTX 1060 graphics card, the two new graphics cards are based on the new architecture, and are added to the VR feature, but also the positioning of high-end. First, let's look at the comparison of GTX1060 and RX480 graphics cards to see what the difference is between the two new graphics cards. 　　RX

Before the adaptation needs to first determine the current cell phone pixel density type (such as: xhdpi, hdpi, MDPI, etc.),The following is an example of Huawei G700, Simulator, to calculate its pixel density.Case one:Phone Model: G700Cell Phone Resolution: 1280*720 (Note: Mobile phone two right-angled side of the 1280 and 720 pixels respectively placed)Cell phone Size: 5 inches (Phone diagonal lengt

, HVGA, and QVGA, and do not rely on pixels. The corresponding formula for dip and specific pixel values is the dip value = device density/160* pixel value, which can be seen on devices with a dpi (pixel density) of 160dpi 1px=1dip sp (scaledpixels magnified pixels) is primarily used for font display (best for TEXTSIZE). According to Google's suggestion, TextView's font size is best to use SP to do units, and view the source of TextView know that Android by default

Adaptation principle: proportional scaling.Because only the width and height are scaled in proportion to1 picture does not deform2 The proportions of the long and wide coordinates that are logically formed are consistent. For example, the width 2pt represents 4 pixels, the height 2pt represents 4 pixels, does not appear the same logical length actually represents the pixel length is different.Like what:The adaptation is primarily for background images and UI elements.11 Background picture width

PX: is the pixel of the screen in: inches MM: millimeter PT: LB, 1/72 inch DP: A density-based abstract unit, 1dp = 1px dip: equivalent to dp SP: it is similar to DP, but it also scales according to the user's font size preference.
