Android 适配刘海屏之 判断手机是否是刘海屏

话不多说 直接上代码

判断vivo是否有刘海屏

/**

    private static boolean hasNotchVIVO() {
        try {
            Class<?> c = Class.forName("android.util.FtFeature");
            Method get = c.getMethod("isFeatureSupport", int.class);
            return (boolean) (get.invoke(c, 0x20));
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }

判断oppo是否有刘海屏

/**

     * @return

    private static boolean hasNotchOPPO(Activity activity) {
        return activity.getPackageManager().hasSystemFeature("com.oppo.feature.screen.heteromorphism");
    }

小米刘海屏判断

/**

     *
     * @param activity
     * @return
     */
    private static boolean hasNotchXiaoMi(Activity activity) {
        return getInt("ro.miui.notch", activity) == 1;
    }

    /**

     *
     * @return 0 if it is not notch ; return 1 means notch
     * @throws if the key exceeds 32 characters
     */
    public static int getInt(String key, Activity activity) {
        int result = 0;
        try {
            ClassLoader classLoader = activity.getClassLoader();
            @SuppressWarnings("rawtypes")
            Class SystemProperties = classLoader.loadClass("android.os.SystemProperties");
            //参数类型
            @SuppressWarnings("rawtypes")
            Class[] paramTypes = new Class[2];
            paramTypes[0] = String.class;
            paramTypes[1] = int.class;
            Method getInt = SystemProperties.getMethod("getInt", paramTypes);
            //参数
            Object[] params = new Object[2];
            params[0] = new String(key);
            params[1] = new Integer(0);
            result = (Integer) getInt.invoke(SystemProperties, params);

        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {

        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
        return result;
    }

判断华为是否有刘海屏

/**

     *
     * @param activity
     * @return
     */
    private static boolean hasNotchHw(Activity activity) {

        try {
            ClassLoader cl = activity.getClassLoader();
            Class HwNotchSizeUtil = cl.loadClass("com.huawei.android.util.HwNotchSizeUtil");
            Method get = HwNotchSizeUtil.getMethod("hasNotchInScreen");
            return (boolean) get.invoke(HwNotchSizeUtil);
        } catch (Exception e) {
            return false;
        }
    }

可以稍微抽取以下工具类

/**
     * 是否有刘海屏
     *
     * @return
     */
    public static boolean hasNotchInScreen(Activity activity) {
        // android  P 以上有标准 API 来判断是否有刘海屏
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            View decorView = activity.getWindow().getDecorView();
            WindowInsets windowInsets = decorView.getRootWindowInsets();
            if (windowInsets != null) {
                DisplayCutout displayCutout = windowInsets.getDisplayCutout();
                if (displayCutout != null) {
                    List<Rect> rects = displayCutout.getBoundingRects();
                    //通过判断是否存在rects来确定是否刘海屏手机
                    if (rects != null && rects.size() > 0) {
                        return true;
                    }
                }
            }
        }
        // 通过其他方式判断是否有刘海屏  目前官方提供有开发文档的就 小米，vivo，华为（荣耀），oppo
        String manufacturer = Build.MANUFACTURER;
        if (StringUtils.isEmpty(manufacturer)) {
            return false;
        } else if (manufacturer.equalsIgnoreCase("HUAWEI")) {
            return hasNotchHw(activity);
        } else if (manufacturer.equalsIgnoreCase("xiaomi")) {
            return hasNotchXiaoMi(activity);
        } else if (manufacturer.equalsIgnoreCase("oppo")) {
            return hasNotchOPPO(activity);
        } else if (manufacturer.equalsIgnoreCase("vivo")) {
            return hasNotchVIVO(activity);
        } else {
            return false;
        }
    }

至此 目前只做了这几款的校验 有需要后面补齐
