试试这个函数isLayoutSizeAtLeast(int screenSize)

检查小屏幕，至少320x426 dp及以上 .getConfiguration getresource () () .isLayoutSizeAtLeast (Configuration.SCREENLAYOUT_SIZE_SMALL);

检查正常屏幕，至少320x470 dp及以上 .getConfiguration getresource () () .isLayoutSizeAtLeast (Configuration.SCREENLAYOUT_SIZE_NORMAL);

检查大屏幕，至少480x640 dp及以上 .getConfiguration getresource () () .isLayoutSizeAtLeast (Configuration.SCREENLAYOUT_SIZE_LARGE);

检查超大屏幕，至少720x960 dp及以上 .getConfiguration getresource () () .isLayoutSizeAtLeast (Configuration.SCREENLAYOUT_SIZE_XLARGE);

难道不能使用字符串资源和枚举来做到这一点吗?您可以定义一个字符串资源，该资源具有屏幕大小的名称，例如SMALL、MEDIUM或LARGE。然后，您可以使用string资源的值来创建枚举的实例。

Define an Enum in your code for the different screen sizes you care about. public Enum ScreenSize { SMALL, MEDIUM, LARGE,; } Define a string resource, say screensize, whose value will be either SMALL, MEDIUM, or LARGE. <string name="screensize">MEDIUM</string> Put a copy of screensize in a string resource in each dimension you care about. For example, <string name="screensize">MEDIUM</string> would go in values-sw600dp/strings.xml and values-medium/strings.xml and <string name="screensize">LARGE</string> would go in sw720dp/strings.xml and values-large/strings.xml. In code, write ScreenSize size = ScreenSize.valueOf(getReources().getString(R.string.screensize);

Jeff Gilfelt对静态助手方法的回答是:

private static String getSizeName(Context context) {
    int screenLayout = context.getResources().getConfiguration().screenLayout;
    screenLayout &= Configuration.SCREENLAYOUT_SIZE_MASK;

    switch (screenLayout) {
    case Configuration.SCREENLAYOUT_SIZE_SMALL:
        return "small";
    case Configuration.SCREENLAYOUT_SIZE_NORMAL:
        return "normal";
    case Configuration.SCREENLAYOUT_SIZE_LARGE:
        return "large";
    case 4: // Configuration.SCREENLAYOUT_SIZE_XLARGE is API >= 9
        return "xlarge";
    default:
        return "undefined";
    }
}

您可以使用配置。screenLayout位掩码。

例子:

if ((getResources().getConfiguration().screenLayout & 
    Configuration.SCREENLAYOUT_SIZE_MASK) == 
        Configuration.SCREENLAYOUT_SIZE_LARGE) {
    // on a large screen device ...

}
