Android: Align Parent Bottom + Bottom margin

Android Problem Overview

I've used a relative layout and I want to set the button at bottom of the screen, However this puts it all the down to the bottom and I would like to have some margin so it there's some space between the end of the screen/view and the button. However whatever I do the button margin just doesn't do anything on 2.1+ for some reason. The relative layout contains a background so I cant but the margin on that.

Anyone know a fix for this?

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="0dp"
android:background="@drawable/background" >

    <Button
        android:id="@+id/confirm_mobile_button_next"
        android:layout_width="fill_parent"
        android:layout_height="40dip"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="false"
        android:layout_centerHorizontal="false"
        android:layout_centerInParent="false"
        android:layout_margin="15dp"
        android:background="@drawable/button_shape_selector"
        android:paddingLeft="10dip"
        android:paddingRight="10dip"
        android:text="@string/confirm_mobile_no_continue"
        android:textColor="@color/white"
        android:textStyle="bold" />

</RelativeLayout>

Solution 1 - Android

You can simply add a padding to the RelativeLayout instead of a margin to the Button, e.g. android:paddingBottom="15dp".

In general I'm always testing my layout in the Exclipse preview using API Level 8 setting. This gives quite accurate results for most devices, including ICS and JB.

Solution 2 - Android

The other thing you can do is put a View that's aligned to the bottom of the RelativeLayout, and set its height to the bottom margin you would want to use (or simply specify a value for layout_marginBottom) like so:

 <RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"        
    > 
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/some_image"
        android:adjustViewBounds="true"
        
         />
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Some Overlay"
        android:padding="3dip"
        android:gravity="center_vertical|center_horizontal"
                  
        android:layout_above="@+id/empty_view"
        android:layout_marginBottom="35dip"
        />
    <View 
        android:id = "@+id/empty_view"
        android:layout_height = "30dip"
        android:layout_width = "match_parent"
        android:visibility="invisible"
        android:layout_alignParentBottom="true"
        />
    
    </RelativeLayout>

This example fills the RelativeLayout with the ImageView, and positions a TextView over the ImageView.

Yu can use translateY attribute

translateY="-16dp"

Final code

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="0dp"
    android:background="@drawable/background">

    <Button
        android:id="@+id/confirm_mobile_button_next"
        android:layout_width="fill_parent"
        android:layout_height="40dip"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="false"
        android:layout_centerHorizontal="false"
        android:layout_centerInParent="false"
        android:layout_margin="15dp"
        android:background="@drawable/button_shape_selector"
        android:paddingLeft="10dip"
        android:paddingRight="10dip"
        android:text="@string/confirm_mobile_no_continue"
        android:textColor="@color/white"
        android:textStyle="bold"
        android:translateY="-16dp" />

</RelativeLayout>

Solution 4 - Android

only working solution suggested by @franny zhao is below.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <FrameLayout
        android:id="@+id/fl_layout"
        android:layout_alignParentBottom="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <TextView
            android:id="@+id/tv_layout"
            android:text="hello world"
            android:layout_marginBottom="50dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </FrameLayout>
</RelativeLayout>

If you add padding to the bottom aligned view as suggested by others, the view background will also extend. If you have colored background then the view will look like it is glued to the bottom. Padding and margin are entirely different, padding is part of view, but margin leaves space between views.

I think the best way is to set android:layout_alignParentBottom in XML then in java code behind:

Button confirm_mobile_button_next = (Button)findViewById(R.id.confirm_mobile_button_next)

and

confirm_mobile_button_next.setTransitionY(-THE_VALUE) or setTransitionX(-THE_VALUE)

Solution 6 - Android

I think the best way is to set:

<...
android:layout_alignParentBottom="true" />

then in java code behind:

Button confirm_mobile_button_next = (Button)findViewById(R.id.confirm_mobile_button_next)
confirm_mobile_button_next.setTransitionY(-THE_VALUE) or setTransitionX(-THE_VALUE)

You can use a ViewGroup(for example, FrameLayout or LinearLayout) to wrap the view. Set alignParentBottom in the outside ViewGroup, then marginBottom can work in the inside View.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <FrameLayout
        android:id="@+id/fl_layout"
        android:layout_alignParentBottom="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <TextView
            android:id="@+id/tv_layout"
            android:text="hello world"
            android:layout_marginBottom="50dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </FrameLayout>
</RelativeLayout>

Solution 8 - Android

Since I stumbled upon this issue, and saw no answers fit to my situation I started thinking for half a second and resolved it by setting a negative margin on the view inside the RelativeLayout sample:

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ImageView
    android:layout_width="48dp"
    android:layout_height="48dp"
        android:layout_marginTop="-8dp"
        android:layout_marginStart="-8dp">
</RelativeLayout>

This should prove useful to some people.

Solution 9 - Android

Try in this way :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:tools="http://schemas.android.com/tools"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent" >

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="17dp"
    android:text="Button" />

Here is another alternative. If you want to set the child's margin instead of parent's padding, you should set the value of android:layout_marginTop to double of the desired margin and then set the android:layout_centerVertical to true. Top margin is given double the desired value to compensate the bottom margin. That way you will have an equal top and bottom margin around the child view.

http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginBottom="0dp" android:background="@drawable/background" >

<Button
    android:id="@+id/confirm_mobile_button_next"
    android:layout_width="fill_parent"
    android:layout_height="40dip"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="false"
    android:layout_centerVertical="true"
    android:layout_centerInParent="false"
    android:layout_marginLeft="15dp"
    android:layout_marginRight="15dp"
    android:layout_marginTop="30dp"
    android:background="@drawable/button_shape_selector"
    android:paddingLeft="10dip"
    android:paddingRight="10dip"
    android:text="@string/confirm_mobile_no_continue"
    android:textColor="@color/white"
    android:textStyle="bold" />

It will give you the same result.
