如何将导航抽屉包含到我的XML布局文件中

Question

I have xml layout main_activity.xml and the root layout element is LinearLayout. I want to include navigation drawer in my application. so I created a menu.xml and header.xml layout file. Then I included the code for the drawer into my activity_main.xml. but it is not working. I think it might be b/c the root element needs to be DrawerLayout. But if I change LinearLayout to DrawerLayout, then my xml is all messed up. It can't find the listview or make sense of the views in the page. I have include the appropiate plugins in my gradle file in order to add DrawerLayout. How can I include navigation drawer in my app. Thanks main_activity.xml file

Answer 1

Have you add this to your activity ?

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
     this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();

EDIT : You right you have to use a Drawer Activity, you could use an "include" in your layout like this

<android.support.v4.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:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/content_visualisation"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_visualisation"
        app:menu="@menu/activity_visualisation_drawer"/>

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