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 ...

}

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);

感谢上面的回答，这对我帮助很大:-)但对于那些(像我一样)被迫仍然支持Android 1.5的人，我们可以使用java反射来向后兼容:

Configuration conf = getResources().getConfiguration();
int screenLayout = 1; // application default behavior
try {
    Field field = conf.getClass().getDeclaredField("screenLayout");
    screenLayout = field.getInt(conf);
} catch (Exception e) {
    // NoSuchFieldException or related stuff
}
// Configuration.SCREENLAYOUT_SIZE_MASK == 15
int screenType = screenLayout & 15;
// Configuration.SCREENLAYOUT_SIZE_SMALL == 1
// Configuration.SCREENLAYOUT_SIZE_NORMAL == 2
// Configuration.SCREENLAYOUT_SIZE_LARGE == 3
// Configuration.SCREENLAYOUT_SIZE_XLARGE == 4
if (screenType == 1) {
    ...
} else if (screenType == 2) {
    ...
} else if (screenType == 3) {
    ...
} else if (screenType == 4) {
    ...
} else { // undefined
    ...
}

在2018年，如果你需要Jeff在Kotlin中的回答，下面是:

  private fun determineScreenSize(): String {
    // Thanks to https://stackoverflow.com/a/5016350/2563009.
    val screenLayout = resources.configuration.screenLayout
    return when {
      screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK == Configuration.SCREENLAYOUT_SIZE_SMALL -> "Small"
      screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK == Configuration.SCREENLAYOUT_SIZE_NORMAL -> "Normal"
      screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK == Configuration.SCREENLAYOUT_SIZE_LARGE -> "Large"
      screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK == Configuration.SCREENLAYOUT_SIZE_XLARGE -> "Xlarge"
      screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK == Configuration.SCREENLAYOUT_SIZE_UNDEFINED -> "Undefined"
      else -> error("Unknown screenLayout: $screenLayout")
    }
  }

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 ...

}
