问题：
Android--如何制作像facebook、spotify和Google+一样的幻灯片菜单

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/zwemfest" >"
<com.devspark.sidenavigation.SideNavigationView
android:id="@+id/side_navigation_view"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="@+id/button1"

android:layout_height="113dp"
android:layout_weight="0.91"
android:text="Button" />
</com.devspark.sidenavigation.SideNavigationView>
</RelativeLayout>
但我没有看到任何按钮或背景图像。你知道哪里出了问题吗？

好吧，目前我正在做一个项目，遇到了滑动菜单，我谷歌了，但失望地看到，没有人给出一些指导或提示如何开始制作滑动菜单，每个人都给了一些GitHub的项目/库的链接使用，因此我决定自己做，最后我有自己的滑动菜单准备好了...
我花了两天时间在这上面
