Question

我想在我的Android应用程序中显示背景图像适合移动设备所有屏幕分辨率的理想图像尺寸（宽度和高度）是多少？

Answer 1

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，这样你就不会在更大的屏幕上放松质量，继承人的图表我已经离开了这里

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
