Question

Im getting started with android development and i have a few questions about supporting different screen sizes. I have read all about it here but still dont get how to use different sized images for different screens. My situation is that I have put an image in res/drawable/hdpi which will be picked up when running on my samsung infuse 4g as well as on my galaxy 10.1 tablet. Because they have the same density class the image will have roughly the same physical size on both devices. And this is the problem, obviously I want the image to be way bigger on my tablet but I have yet not found a way to do this.

I did look at another classification whith small, medium and large but that seemed only to be applicable to layouts and not image resources.

Any pointers would be appreciated.

Thanks!

Answer 1

After putting images into for example

/res/layout-480x800` - if you know resolution
/res/layout-w480dp - if you know witdh
/res/layout-h800dp - if you know height

Android automaticly choose picture for you. Just put picture in resolutions but with the same name into this subfolders. Then just use (without spacyfing qualifiers):

android:src="@drawable/background"

or

imageView.setImageResource(R.drawable.background);

The order of precedence of qualifiers can be found in documentation (Table 2)
