I'm centering properly, as you can see when you look at the content_main.xml design tab,
However, when you look activity_main.xml design with the action bar in place, while it is still centred in the app, it is not centred within the whitespace, which is what I would prefer. Any suggestions on how to account for the action bar? Preferably in the XML if possible.
Here is my XML
<?xml version="1.0" encoding="utf-8"?>

But you need to run it on the device or emulator. Android Studio preview shows it wrong. The key line is app:layout_behavior="#string/appbar_scrolling_view_behavior"
EDIT
Also you need to use RelativeLayout - it supports good centering in parent. In LinearLayout you can center image only if your ImageView will be match_parent.

Android studio screenshotI have an EditText which I set the width to 0dp but made the weight 1 so that it still spans across the screen and the height is wrap_content but for some reason, it just comes up as a line going right down the screen with no width. Could you please help me to get this right?

Your problem is in
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"/>
it should be
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
</LinearLayout>
#Zid
First of all the parent RelativeLayout is not useful in your design
Second of all you was closing your second LinearLayout there only thats why it was giving you issue.
so please check following design code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

I am attempting to put a FAB on a fragment. The problem is that the background graphic (it is a plus sign) is not showing up in the circle, it just looks like a solid circle of color at the bottom. Here is my layout:
<?xml version="1.0" encoding="utf-8"?>

What am I doing wrong?
I needed to add:
android:src="#drawable/plus_circle
to the FAB layout.
This is the preview in the designer.
But when I run the app on a device (Galaxy S4 with 5.0.1) the bottom part of the fragment gets cut off.
chat_fragment.xml
<?xml version="1.0" encoding="utf-8"?>

<EditText

<ImageButton

android:layout_gravity="center_vertical"
android:scaleType="fitEnd"
android:backgroundTintMode="multiply"

</LinearLayout>
</RelativeLayout>
Is this because of something that I should handle from the layout of the fragment?
I changed youx xml code. Just little changes . Use this layout
<?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:orientation="vertical">

android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll"
android:background="#1b184b"
android:layout_alignParentTop="true"
android:layout_above="#+id/edit_linear_layout"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="48dip"
android:layout_alignParentBottom="true"
android:padding="0dp"
android:layout_margin="0dp"
android:background="#753636"
android:orientation="horizontal"
android:id="#+id/edit_linear_layout"
>
<EditText
android:layout_width="345dp"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:hint="Send a message"
android:id="#+id/newmsg"
/>
<ImageButton
android:id="#+id/newmsgsend"
android:src="#drawable/ic_send"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:scaleType="fitEnd"
android:backgroundTintMode="multiply"
android:backgroundTint="#400202" />
</LinearLayout>
</RelativeLayout>
You can add bottom margin to your bottom most item to resolve the "cut off" issue.
android:layout_marginBottom="50dp"
In your case, change your ImageButton to the following
<ImageButton
android:id="#+id/newmsgsend"
android:src="#drawable/ic_send"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_vertical"
android:scaleType="fitEnd"
android:backgroundTintMode="multiply"
android:backgroundTint="#400202"
android:layout_marginBottom="50dp" />
I have an activity with a TextView. I would like to align it on the bottom of the screen, in the center and I would like that the TextView fits the screen's width.
This is my XML:
<RelativeLayout 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:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:background="#ffffff"
tools:context=".ShowCard" >
<TextView
android:id="#+id/textView"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#33000000"
android:textColor="#000000"
android:text="#string/lorem_ipsum" />
The result is not what I have expected to see. The TextView is not full-screen in the width, but leaves a small free space right and left (like padding/border, but I've not set padding/border!).
Do you know why? Suggestions?
try 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" >
<TextView
android:id="#+id/textView"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#33000000"
android:textColor="#000000"
android:text="#string/lorem_ipsum" />
</RelativeLayout>
Excuse me, I'm a stupid guy!
I've not see that in the container XML code were included four padding rows:
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
I've deleted these rows and now everything is working correctly!
Sorry.
<TextView
android:id="#+id/textView"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#33000000"
android:textColor="#000000"
android:text="#string/lorem_ipsum" />
Use the 'fill_parent' attribute, it should fill the entire width of the screen.
remove
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
from the parent relative layout.
<RelativeLayout 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="#ffffff"
tools:context=".ShowCard" >
<TextView
android:id="#+id/textView"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#33000000"
android:textColor="#000000"
android:text="#string/lorem_ipsum" />
use this
I have a Button, I can align it by the distance from top.
<RelativeLayout 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="#drawable/m1"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".OtherScreenActivity1" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="99dp"
android:background="#drawable/btn" />
</RelativeLayout>
But I want to align its position by the distance from bottom, not from top, and it does not work, it stays stick on bottom.
<RelativeLayout 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="#drawable/m1"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".OtherScreenActivity1" >
<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="99dp"
android:background="#drawable/btn" />
</RelativeLayout>
Not sure what the problem is but this what I have currently and the code seems to be working properly
<RelativeLayout 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:paddingBottom="10dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="10dp"
tools:context=".OtherScreenActivity1" >
<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="99dp"
/>
Try this code and see if the xml is what you are looking for.
