I’m developing an app which has different layout and value files for various screens, then I meet a problem: The smallestWidth qualifier only checks if the device smallestWidth is GREATER than indicated value.

This is troublesome when I have below folder structure:

res/layout-port-mdpi
res/layout-sw720dp
res/layout-sw720dp-port
res/layout-sw720dp-land

In this case, on a mdpi sw720 port device, Android will use res/layout-port-mdpi rather than res/layout-sw720dp-port which I really want to use. The res/layout-port-mdpi is for smaller phones.

Is there a way to indicate smallestWidth LESS than like 719dp, or should I need to create res/layout-sw720dp-port-mdpi and for all other dpis? It sounds so stupid.

Thank you for the kind answer.

    The res/layout-port-mdpi is for smaller phones.

    No, it is not. It is for portrait devices with medium density screens. It stipulates nothing with respect to size.

    In this case, on a mdpi sw720 port device, Android will use res/layout-port-mdpi rather than res/layout-sw720dp-port which I really want to use.

    No. -sw720dp is a stronger criterion than is -mdpi, so for a device that is -sw720dp and -mdpi and is held in portrait, res/layout-sw720dp-port should be used.

    Is there a way to indicate smallestWidth LESS than like 719dp

    Not really. Android will use a resource set that does not have any -swNNNdp value if the device’s value is lower than any such resource set you use.

    should I need to create res/layout-sw720dp-port-mdpi and for all other dpis?

    No.

    For example, if your objective is to have some layouts used specifically for -sw720dp devices and other layouts used for smaller devices, with some different layouts for landscape for each size, your directories would be:

    • res/layout-sw720dp-land/ for -sw720dp devices in landscape orientation
    • res/layout-sw720dp/ for -sw720dp devices not in landscape orientation
    • res/layout-land/ for smaller than -sw720dp devices held in landscape
    • res/layout/ for smaller than -sw720dp devices not in landscape orientation

    Have one of every layout in res/layout/, and override those layouts in resource sets with more constraints only where needed.
