RelativeLayout, Include und layout_alignParentBottom funktionieren nicht

Question

Wie lasse ich mein Include genau am Ende des Bildschirms? Zu dem Zeitpunkt, zu dem er das Ende des Inhalts erreicht.

Answer 1

Das Problem ist, dass Ihre ScrollerView ein layout_height="fill_parent" hat. RelativeLayout macht diese Ansicht füllen den gesamten Raum.

Ein LinearLayout wird in Ihrem Fall besser funktionieren:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:background="#f6ba79"
        android:orientation="vertical"
        android:id="@+id/layout">

        ...

    </ScrollView>
    <include
        android:id="@+id/include1"
        android:layout_width="fill_parent"
        layout="@layout/menu"
        android:layout_height="wrap_content" />
</LinearLayout>

Der Schlüssel dazu ist, die Höhe der ScrollerView eingestellt auf 0dp und das Gewicht wird auf 1 (oder eine beliebige Zahl). LinearLayout streckt dann die ScrollerView so, dass sie die Ansicht ausfüllt und noch Platz für die @layout/menu am unteren Rand.
