用Studio没有多久的人也许会报这个错，下面我们来解决下：

第一次用Studio写侧滑的朋友也许都在迷茫，是用libs呢还是用jar呢，其实可以自己来写，我的csdn中有这个案例，看看解决方法吧：

是因为布局文件的包名错了，因为是复制以前的布局，所以有时候会疏忽（下面是修改前的布局）：

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.administrator.myslidingmenu.MainActivity">    <com.example.slidemenu.view.SlideMenu        android:id="@+id/slideMenu"        android:layout_width="match_parent"        android:layout_height="match_parent">        <!--菜单界面的布局-->        <include layout="@layout/layout_menu"/>        <!--主界面的布局-->        <include layout="@layout/layout_main"/>    </com.example.slidemenu.view.SlideMenu></RelativeLayout></span>

修改后的布局：

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.administrator.myslidingmenu.MainActivity">    <com.example.administrator.myslidingmenu.SlideMenu        android:id="@+id/slideMenu"        android:layout_width="match_parent"        android:layout_height="match_parent">        <!--菜单界面的布局-->        <include layout="@layout/layout_menu"/>        <!--主界面的布局-->        <include layout="@layout/layout_main"/>    </com.example.administrator.myslidingmenu.SlideMenu></RelativeLayout></span>

*** 把包名改成自己当前项目的包名就可以了 ***
