注册刘海显示

                    int mIsNotchSwitchOpen = Settings.Secure.getInt(getContentResolver(),DISPLAY_NOTCH_STATUS, 0);
                    Toast.makeText(content, "华为手机状态值=" + (mIsNotchSwitchOpen==0?"显示区域":"覆盖耳朵区域"), Toast.LENGTH_LONG).show();

注册刘海屏

获取是否以开启刘海设置
 Settings.Global.getInt(content.getContentResolver(), "force_black", 0) == 1//覆盖区域耳朵"

获取状态兰高度 高度比刘海大一点
  public int getstatus(Context content){
        int result=0;
        int resourceId = content.getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 0) {
            result = content.getResources().getDimensionPixelSize(resourceId);
        }

        return result;
        }
