Question

我有xml布局main_activity.xml，而根布局元素是LinearLayout。我想在我的应用程序中包含导航抽屉。所以我创建了menu.xml和header.xml布局文件。然后，将抽屉的代码包含在我的activity_main.xml中。但它不起作用。我认为可能是b / c，根元素需要为DrawerLayout。但是，如果我将LinearLayout更改为DrawerLayout，那么我的xml就会一团糟。它找不到列表视图或无法理解页面中的视图。我已经在我的gradle文件中包含了适当的插件，以便添加DrawerLayout。如何在应用程序中包含导航抽屉。谢谢 main_activity.xml文件

Answer 1

您已将其添加到活动中吗？

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();

编辑：正确，您必须使用“抽屉活动”，您可以在布局中使用“包含”

<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>

如何将导航抽屉包含到我的XML布局文件中
