Android中所有ldpi，mdpi，hdpi，xhdpi的单个图像

Question

Perhaps we use one image for all ldpi, hdpi, mdpi and xdpi where we need to keep the image(in which folder). This is a bit confusion to me. Can anybody clarify my confusion?

Answer 1

只需将其保存在res/drawable 。

Answer 2

This is not recommended as the images you use will then not scale well for different device screen sizes. But if you place an image in res/drawable this will work.

Answer 3

Instead of creating all of the different folder buckets, drawable-ldpi , drawable-hdpi , etc. Just create one folder, drawable , and then put your images in there and when Android searchs for the image and doesn't find the other folders it will default to the drawable folder as the only resource. This folder is understood by Android to be equal to the drawable-mdpi and will scale the images accordingly.

EDIT: Also available is the res/drawable-nodpi , This will not scale your image at all and it will retain the same size on all screens.

Answer 4

Take a look at How to Support Multiple Screens

The "default" resources are those that are not tagged with a configuration qualifier. For example, the resources in drawable/ are the default drawable resources. The system assumes that default resources are designed for the baseline screen size and density, which is a normal screen size and a medium density. As such, the system scales default density resources up for high-density screens and down for low-density screens, as appropriate.

So yes, drawable folder is what you are looking for.
