可绘制尺寸：LDPI，MDPI，HDPI，XHDPI，XXHDPI，XXXHDPI？

Question

建议可绘制的尺寸是什么：LDPI，MDPI，HDPI，XHDPI，XXHDPI，XXXHDPI或i可以对所有尺寸使用相同尺寸的图像，并以编程方式更改它，例如更改宽度和高度？

Answer 1

Inside Android Studio, if you right click on the res folder, you can select New > Image Asset which will create properly sized drawables for those dpi bucket folders.

Optionally, you can also use a website like this one: http://romannurik.github.io/AndroidAssetStudio/index.html

You can also programmatically change width/height, but this is heavily discouraged due to how disgusting a smaller image looks when it's stretched large. Only use this programmatic solution if you use vector images.

Answer 2

The relationship between the various proportions is as follows:

LDPI - 0.75x
MDPI - 1.0x (original size)
HDPI - 1.5x
XHDPI - 2.0x
XXHDPI - 3.0x
XXXHDPI - 4.0x
