检查应用是否有通知栏权限以及跳转到通知栏设置

1. 检查是否有通知栏权限

public boolean canShowNotification(Context context) {
        return NotificationManagerCompat.from(context).areNotificationsEnabled();
}

2. 打开通知栏权限设置

/**
     * 跳转到打开通知栏界面
     */
    public void requestNotification(Context context) {
        Intent intent = new Intent();
        if (Build.VERSION.SDK_INT >= 26) {// android 8.0引导
            intent.setAction("android.settings.APP_NOTIFICATION_SETTINGS");
            intent.putExtra("android.provider.extra.APP_PACKAGE", context.getPackageName());
        } else if (Build.VERSION.SDK_INT >= 21) { // android 5.0-7.0
            intent.setAction("android.settings.APP_NOTIFICATION_SETTINGS");
            intent.putExtra("app_package", context.getPackageName());
            intent.putExtra("app_uid", context.getApplicationInfo().uid);
        } else {//其它
            intent.setAction("android.settings.APPLICATION_DETAILS_SETTINGS");
            intent.setData(Uri.fromParts("package", context.getPackageName(), null));
        }
        //intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
