【问题描述】：
首先，对不起我的英语不好。
在我的应用程序中，我希望左侧有一个导航抽屉。如果我用一个 ListView 来做，它工作得很好。现在我想在线性布局上做。但它不起作用。
实际上，linearLayout 显示在开头，我无法通过滑动或主页按钮或列表中的项目来隐藏它。当我触摸项目或主页按钮时，应用程序崩溃。
我给你我的代码。
activity_main.xml：
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/grisFond">
[ ... ]
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@+id/Player"
android:id="@+id/container">
</FrameLayout>
</RelativeLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/lin"
android:gravity="left">
<ListView android:id="@+id/my_drawer"
android:layout_width="248dp"
android:layout_height="fill_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="@color/fondMenu"/>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
我准确地说 DrawerLayout 是根，它有 2 个孩子。第一个孩子是包含我的片段的 frameLayout，第二个孩子是我的导航抽屉
现在我的 MainActivity.java 文件：

当我触摸一个项目或主页按钮时我的错误：

关于第 297 行的信息：
mDrawerLayout.closeDrawer(monLayout);
第 282 行：
选择项目（位置）；
第 40 行是我的 MainActivity 类的开始。
我家有个天才会为我解答的。
非常感谢。
