拉伸Android设备的图像

Question

I have been programming an application for Android. I want to target it for more devices(tablets, smartphones). I tried to find some info at http://developer.android.com/guide/practices/screens_support.html but it does not work correctly.

I want to automatically stretch images on different devices, not only in my testing device. I draw images for the mobile full screen (which has the same resolution as my mobile). But, for example in the tablet it draws incorrectly. I tried to change the size and it gives several folders(lhdpi, small, ...). When I tried to start it again in the tablet, it was bigger but still incorrect (there was a black space on the edges). I have several images in my application, and I want to retain the same size as in the mobile too. Please, help me.

Sorry for my spelling mistakes.

Answer 1

you have to maintain aspect ratio at your own . don't put same sized images in all folder (hdli, mdpi, ldpi), if this was the case they think why android provides different foldes ? put images in ratio 0.75 : 1 : 1.5 . it will work . additionally read about 9-patch images, this will make your life much easier .
