Solution 1
Change your Button layout like this:
<RelativeLayout
android:id="@+id/ButtonLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom" >
<Button
android:id="@+id/add_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10sp"
android:onClick="editItem"
android:layout_alignParentBottom="true"
android:text="@string/button_edit" />
</RelativeLayout>
Solution 2
This should work -
- Use Relative layout as a child for the scroll view .
- Set
layout_alignParentBottom = true
for the Button.
Sample XML
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
android:fillViewport="true"
android:focusableInTouchMode="true"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
tools:context=".ItemDetailActivity" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- Name -->
<RelativeLayout
android:id="@+id/top_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top" >
<TextView
android:id="@+id/name_label"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Name" />
<TextView
android:id="@+id/name_value"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/name_label" />
</RelativeLayout>
<!-- button -->
<RelativeLayout
android:id="@+id/ButtonLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<Button
android:id="@+id/add_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10sp"
android:onClick="editItem"
android:text="Edit" />
</RelativeLayout>
</RelativeLayout>
</ScrollView>
Solution 3
In scroll view, use RelativeLayout instead of LinearLayout and set your bottom view property
android:layout_alignParentBottom="true"

I have a simple layout with a name on the top, and a button which I want to be at the bottom of the screen, or beyond that in case I add more items.
So I am using a ScrollView with a LinearLayout as follows:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/white" android:fillViewport="true" android:focusableInTouchMode="true" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" tools:context=".ItemDetailActivity" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" > <!-- Name --> <RelativeLayout android:id="@+id/top_content" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="top" > <TextView android:id="@+id/name_label" style="@style/Header_Label_TextView" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/name" /> <TextView android:id="@+id/name_value" style="@style/Value_Label_TextView" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/name_label" /> </RelativeLayout> <!-- button --> <RelativeLayout android:id="@+id/ButtonLayout" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" > <Button android:id="@+id/add_button" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="10sp" android:onClick="editItem" android:text="@string/button_edit" /> </RelativeLayout> <requestFocus /> </LinearLayout>
This is what I get:
How do I make it so that the button appears at the bottom of the screen or beyond. Upon searching online, most answers were to set the `android:fillViewport="true", but that is not helping. What am I doing wrong?
