<androidx.drawerlayout.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/DrawerLayout"
android:background="@color/spark_bg"
tools:context=".Main">
<com.google.android.material.navigation.NavigationView
android:id="@+id/mainNavigView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/navigationheader"
app:menu="@menu/navigationmenu"
/>
this is menu item code that contains id for the item i wanted to press这是包含我要按的项目的 ID 的菜单项代码
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/myOrdersMI"
android:icon="@drawable/ic_list"
android:title="My Orders"
/>
</menu>
To use a DrawerLayout
, position your primary content view as the first child with width and height of match_parent
and no <layout_gravity>
要使用DrawerLayout
, position 您的主要内容视图作为第一个子视图,其宽度和高度为match_parent
并且没有<layout_gravity>
<androidx.drawerlayout.widget.DrawerLayout
...>
<!-- main content goes here -->
<!-- NavigationView -->
<com.google.android.material.navigation.NavigationView
android:layout_gravity="start|left"
../>
</androidx.drawerlayout.widget.DrawerLayout>
