Android導航菜單設置

Question

我研究了在Android上設置導航菜單。我已經找到了一些關於如何設置它的答案，但是我的問題是它甚至不可見，如果這個問題很直接，但是在這個編程語言中真的很新，那麼很抱歉。

這裏是我的代碼：

activity_main.xml文件：

enter code here 

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/activity_main" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    tools:context="com.example.mywindows.neo_datawaysconsultantsandtrainers.MainActivity"> 


    <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:layout_width="match_parent"

    <android.support.v4.widget.DrawerLayout 
     android:id="@+id/drawer_layout" 
     android:layout_height="match_parent" 
     android:layout_width="match_parent"> 





     <TextView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="Hello World!" /> 

     <ListView 
      android:id="@+id/drawer"

      android:layout_gravity="start" 
      android:background="@android:color/white" /> 

    </android.support.v4.widget.DrawerLayout> 


</LinearLayout> 

strings.xml文件：

<resources> 
    <string name="app_name">NEO-DATAWAYS</string> 
    <string name="drawer_opened">Select an item</string> 
    <string name="drawer_closed">NEODATAWAYS</string>

styles.xml文件：

enter code here

[activity_main.xml中]

<FrameLayout android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/fl_activity_main_container" /> 

<ListView android:layout_width="240dp" 
    android:layout_height="match_parent" 
    android:id="@+id/lv_activity_main_nav_list" 
    android:layout_gravity="start" 
    android:choiceMode="singleChoice" 
    android:divider="@android:color/transparent" 
    android:dividerHeight="0dp" 
    android:background="#EDEDED"/>
