Question

我有一个TextView用作DrawerLayout中的标题。但是，TextView与其他菜单项一起滚动。我只希望菜单项滚动。

有什么办法只能使特定项目滚动？

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawerLayout"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Main Screen -->
    <RelativeLayout
        <!-- Stuff -->
    </RelativeLayout>

    <!-- Navigation Drawer -->
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:orientation="vertical">

        <!-- Header that I don't want to scroll in -->
        <TextView
            android:id="@+id/headerOverview2"
            android:layout_width="match_parent"
            android:layout_height="48dp"
            android:background="@color/green"

            android:text="@string/overview"
            android:textSize="28sp"
            android:gravity="center"
            android:includeFontPadding="false"
            android:textColor="@color/white"/>

        <!-- Menu Items -->
        <ListView
            android:id="@+id/navList1"
            android:layout_width="200dp"
            android:layout_height="wrap_content"
            android:divider="@null"
            android:background="@color/white"/>

    </LinearLayout>

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

将viewGroup包装在要设置为滚动的scrollView内。将Header TextView移出scrollView。

let list = ["US" : ["United-States","$"],
            "FR" : ["France","€"],
            "CN" :["China", "¥"]]

let currencies = list.compactMap(Currency.init).sorted()
currencies.map({print($0)})

滚动DrawerLayout中的非滚动标题
