android - 使 Android 抽屉导航可滚动

Question

我有一个包含三个部分的抽屉导航，顶部、中间和底部我需要使中间部分可以滚动。

这是我当前的布局。

    <?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include

            android:paddingLeft="50dp"
            app:headerLayout="@layout/nav_header_main"
            />

<!-- End Bottom Section-->      

    </android.support.design.widget.NavigationView>

如何在我的导航 View 中使中间部分可缩放。

Answer 1

NavigationView 为您提供 attr app:headerLayout 用于添加导航标题。要添加页脚，只需将所需的页脚 View 包装在 NavigationView 中即可，

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    >

    <LinearLayout
        android:background="@android:color/darker_gray"
        android:clickable="true"
        android:id="@+id/ll_header"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:orientation="vertical">

        <TextView
            android:gravity="center"
            android:id="@+id/nav_header_textview"
            android:layout_height="48dp"
            android:layout_width="match_parent"
            android:text="Your Header Text Here" />

    </LinearLayout>

    <android.support.design.widget.NavigationView
        android:layout_below="@+id/ll_header"
        android:layout_above="@+id/ll_footer"
        android:id="@+id/navigation"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        app:menu="@menu/my_navigation_items" >


    </android.support.design.widget.NavigationView>

    <LinearLayout
        android:id="@+id/ll_footer"
        android:background="@android:color/darker_gray"
        android:layout_alignParentBottom="true"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        android:orientation="vertical">

        <TextView
            android:gravity="center"
            android:id="@+id/nav_footer_textview"
            android:layout_height="48dp"
            android:layout_width="match_parent"
            android:text="Your Footer Text Here" />

    </LinearLayout>

</RelativeLayout>

为了举例，我使用了 TextView。
