我想知道设备是否有软导航栏。我为此目的使用以下代码:
val hasNavBar = resources.getIdentifier("config_showNavigationBar", "bool", "android")
if(hasNavBar > 0 && resources.getBoolean(hasNavBar)){
val resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android")
if (resourceId > 0) {
ApiHelper.navHeight = resources.getDimensionPixelSize(resourceId)
}
}
但在某些没有软导航栏的设备上,resources.getDimensionPixelSize(resourceId)
会给出一些高度,hasNavBar
为真。
出现此问题的设备是Redmi Note 4 Pro。我不知道其他设备是否有同样的问题。

我找到了答案。
stackOverflow中有一些功能不起作用,但这很有效。
How to tell whether an android device has hard keys
fun hasSoftKeys(windowManager: WindowManager): Boolean {
var hasSoftwareKeys = true
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
val d = context.getWindowManager().getDefaultDisplay()
val realDisplayMetrics = DisplayMetrics()
d.getRealMetrics(realDisplayMetrics)
val realHeight = realDisplayMetrics.heightPixels
val realWidth = realDisplayMetrics.widthPixels
val displayMetrics = DisplayMetrics()
d.getMetrics(displayMetrics)
val displayHeight = displayMetrics.heightPixels
val displayWidth = displayMetrics.widthPixels
hasSoftwareKeys = realWidth - displayWidth > 0 || realHeight - displayHeight > 0x<
} else {
val hasMenuKey = ViewConfiguration.get(context).hasPermanentMenuKey()
val hasBackKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK)
hasSoftwareKeys = !hasMenuKey && !hasBackKey
}
return hasSoftwareKeys
}
