屏幕图像

我不知道为什么我的抽屉布局上有一个问号，也不知道为什么它不起作用，因为我按照 youtube 教程创建了整个屏幕

这是navigation_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

<item android:id="@+id/home"
    android:title="Home"/>

<item android:id="@+id/myorders"
    android:title="My Orders"/>
<item android:id="@+id/myplaces"
    android:title="My Places"/>

<item android:id="@+id/mensettings"
    android:title="Settings"/>

</menu>

这是 XML 文件：

// this is the name of file navigation_menu.xml//
//firstly you need to make a menu
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

        <item >
     //   here item related things like id and title

        </item>
        <item >
          //   here item related things like id and title

        </item>



</menu>
//then you need to add this in drawer layout

//mainactivity.xml code


<android.support.v4.widget.DrawerLayout>

 //first you take navigation menu and then perform the below process
  //in  android id tag you can add menu bar and you need to add two dependency
//dependency some
  //implementation 'com.android.support:design:27.1.1'
  // implementation 'com.android.support:support-compat:27.1.1'

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

添加这个

dependencies {
    implementation "androidx.drawerlayout:drawerlayout:1.1.1"
}

在 build.gradle 文件中。文档
