不同刘海屏幕获取安全高度

系统获取大于等于9.0才有

decorView.rootWindowInsets?.displayCutout.safeInsetTop  (kotlin)

华为

判断

val cl: ClassLoader = context!!.classLoader
        val HwNotchSizeUtil: Class<*> = cl.loadClass("com.huawei.android.util.HwNotchSizeUtil")
        val get = HwNotchSizeUtil.getMethod("hasNotchInScreen")
        ret = get.invoke(HwNotchSizeUtil) as Boolean

获取

  val cl = context!!.classLoader
        val HwNotchSizeUtil = cl.loadClass("com.huawei.android.util.HwNotchSizeUtil")
        val get: Method = HwNotchSizeUtil.getMethod("getNotchSize")
        ret = get.invoke(HwNotchSizeUtil) as IntArray

小米

判断

com.bilibili.droid.SystemProperties.get("ro.miui.notch", "0") == "1"

获取

  val res = context!!.resources
    var resourceId = res.getIdentifier("notch_height", "dimen", "android");
    if (resourceId > 0) {
        return res.getDimensionPixelSize(resourceId);
    }
    resourceId = res.getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        return res.getDimensionPixelSize(resourceId);
    }

小米有些版本可以通过notch_height获取，有些版本没有直接获取状态栏高度

魅族

判断

var fringeDevice = false
    try {
        val clazz = Class.forName("flyme.config.FlymeFeature")
        val field = clazz.getDeclaredField("IS_FRINGE_DEVICE")
        fringeDevice = field.get(null) as Boolean
    } catch (e: Exception) {
    }


    if (fringeDevice) {
        // 判断隐藏刘海开关(默认关)
        val isFringeHidden = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            Settings.Global.getInt(window.getContext().getContentResolver(),
                    "mz_fringe_hide", 0) == 1
        } else {
            true //当做默认值
        }
        return !isFringeHidden
    }

    return false

获取

val res = context!!.resources
    var notchHeight = 0
    val fhid = res.getIdentifier("fringe_height", "dimen", "android")
    if (fhid > 0) {
        notchHeight = res.getDimensionPixelSize(fhid)
    }

VIVO

判断

        try {
        val cl =context.classLoader
        val vivoFtFeature = cl.loadClass("android.util.FtFeature")
        val get = vivoFtFeature.getMethod("isFeatureSupport", Int::class.javaPrimitiveType!!)
        //表示是否有凹槽
        val VIVO_HAS_NOTCH_DISPLAY:Int = 0x00000020
        return get.invoke(vivoFtFeature, VIVO_HAS_NOTCH_DISPLAY) as Boolean
    } catch (e: Exception) {
        return false
    }

获取

 27dp

OPPO

判断

return window.context.packageManager
                .hasSystemFeature("com.oppo.feature.screen.heteromorphism");

获取

  80

oppo和vivo是默认的高度，没有厂商api
