<div class =“post-text”itemprop =“text”> <P> id说理想将是使用最高的屏幕密度，所以应用程序将缩小它以降低屏幕分辨率，这样你不会在更大的屏幕上放松质量，继承人的图表我离开了这里 </p> <pre> <code> xlarge screens are at least 960dp x 720dp large screens are at least 640dp x 480dp normal screens are at least 470dp x 320dp small screens are at least 426dp x 320dp Generalised Dpi values for screens: ldpi Resources for low-density (ldpi) screens (~120dpi) mdpi Resources for medium-density (mdpi) screens (~160dpi). (This is the baseline density.) hdpi Resources for high-density (hdpi) screens (~240dpi). xhdpi Resources for extra high-density (xhdpi) screens (~320dpi). Therefore generalised size of your resources (assuming they are full screen): ldpi Vertical = 426 * 120 / 160 = 319.5px Horizontal = 320 * 120 / 160 = 240px mdpi Vertical = 470 * 160 / 160 = 470px Horizontal = 320 * 160 / 160 = 320px hdpi Vertical = 640 * 240 / 160 = 960px Horizontal = 480 * 240 / 160 = 720px xhdpi Vertical = 960 * 320 / 160 = 1920px Horizontal = 720 * 320 / 160 = 1440px px = dp*dpi/160 </code> </pre> </DIV>
