In my app screen, i want to show Heading as horizontally center. I tried with below layout xml codes
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="10dip"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Connections" />
</RelativeLayout>
thanks
android:gravity controls the appearance within the TextView. So if you had two lines of text they would be centered within the bounds of the TextView. Try android:layout_centerHorizontal="true".
Use this:
android:layout_centerHorizontal="true"
within TextView
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="10dip"
>
<TextView
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Connections" />
</RelativeLayout>
use layout_centerInParent="true"(layout_centerInHorizontal,layout_centerInVertical)
gravity means the algin of text on textview, not the view itself
replace textview with below code
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_horizontal"
android:text="Connections" />
only add this android:gravity="center_horizontal"
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="10dip"
android:gravity="center_horizontal"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Connections" />
</RelativeLayout>

I have created a very simple layout. XML looks like 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/text_view_download_data_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:text="#string/download_initial_data" />
</RelativeLayout>
The graphic result of this layout looks like this (from Eclipse):
Can you explain me, please, why the text in TextView is not centered horizontally? Thanks in advance.
Remove this line:
android:gravity="center"
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:gravity="center">
<TextView
android:id="#+id/text_view_download_data_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:gravity="center"
android:text="download_initial_data" />
</RelativeLayout>
In my app two button arranged vertically in LinearLayout. i want to provide a gap between two buttons. Please provide a solution...
my layout as follows
<?xml version="1.0" encoding="utf-8"?>

thanks in advance
Add a margin (android:layout_marginTop="50dp") to the top of of the second button:
<?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="wrap_content"
android:orientation="vertical"
android:padding="10dp"
>
<Button
android:id="#+id/btnAction1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/cool_button"
android:text = "HiText1"
/>
<Button android:layout_marginTop="50dp"
android:id="#+id/btnAction2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/cool_button"
android:text="HiText2"
android:layout_below="#id/btnAction1"
/>
</LinearLayout>
use android:layout_marginTop="10dp"
Use android:layout_marginTop="10.0dip" on second button.
use this code for your second button
<Buttonandroid:id="#+id/btnAction2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/cool_button"
android:text="HiText2"
android:layout_marginTop="15dp"
/>
I have the following layout i'd like to make the textview appear in the center and middle of the view. How can i acheive this?
I've tried adjusting the various gravity attributes when looking at the layout in graphical view, but nothing seems to change it. I'd like the textview in the center which i've done but halfway down the view.
thanks matt.
<?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"
android:orientation="vertical"
android:background="#drawable/carefreebgscaledalphajpg" >
<TextView
android:id="#+id/textviewdatefornocallspage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="You have no calls for "
android:textSize="25sp" />
</LinearLayout>
set the gravity to center in your linearLayout tag :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"
android:background="#drawable/carefreebgscaledalphajpg" >
or use a RelativeLayout like 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:background="#drawable/carefreebgscaledalphajpg" >
<TextView
android:id="#+id/textviewdatefornocallspage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="You have no calls for "
android:textSize="25sp" />
</RelativeLayout>
Try this
simple i have tried to many answer but all answers are not working ......finally this methods works for me
<LinearLayout
android:layout_below="#+id/iv_divider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginTop="#dimen/_10dp">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/mycredits"
android:textColor="#color/colorGray"
android:gravity="center"
android:textSize="#dimen/_25dp" />
</LinearLayout>
Set android:gravity="center" attribute for TextView inside linear layout and keep the text view's height and width as wrap_content.
This Solution worked for me.
<TextView
...
android:layout_gravity="center"
....
/>
Set width of your textview to wrap_content, and set your LinearLayout to
android:gravity="center_horizontal"
Add android:gravity="center_horizontal" to your LinearLayout and alter your TextView's layout_width as android:layout_width="wrap_content"
<?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"
android:orientation="vertical"
android:gravity="center_horizontal"
android:background="#drawable/carefreebgscaledalphajpg" >
<TextView
android:id="#+id/textviewdatefornocallspage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="You have no calls for "
android:textSize="25sp" />
</LinearLayout>
None of the other answers worked for me. I had to use android:textAlignment="center"
My layouts were as follows
<LinearLayout...
<RelativeLayout...
<RelativeLayout....
<TextView
android:layout_centerInParent="true"
android:textAlignment="center"
If in linearlayout your orientation vertical, you can put the textview in the "horizontal center" by android:layout_gravity="center". For centering textview vertically you need to set layout_height of textview to match_parent and set android:gravity to "center". If you want to use more than one view in this layout, you should use RelativeLayout and set
android:layout_centerInParent="true".
<LinearLayout
android:id="#+id/service_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/card_view"
android:layout_marginTop="10dp"
android:background="#color/app_bar_background"
android:orientation="vertical">
<TextView
android:id="#+id/list_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fontFamily="sans-serif"
android:gravity="center"
android:singleLine="true"
android:text="#string/Services"
android:textColor="#color/app_bar_text"
/>
</LinearLayout>
Sounds like you want android:layout_gravity for the TextView
see docs: developer.android.com
set android:gravity="center" in your Linear Layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".view.fragments.FragmentAncRecords">
<TextView
android:id="#+id/tvNoDataFound"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fontFamily="#font/poppins_regular"
android:visibility="visible"
android:gravity="center"
android:text="#string/no_record_available"
/>
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rvAncRecords"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:visibility="gone"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager" />
</LinearLayout>
center your texteView in RelativeLayout :
<?xml version="1.0" encoding="utf-8"?>
<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"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
/>
</RelativeLayout>
Use Relative Layout, it always gives more accurate and flexible layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
I can't understand why the following code places my TextView in the top left corner of my screen. Based on my understanding of layout_gravity, it seems that it should place my TextView at the bottom of my screen instead.
Can anyone please shed some light on this for me? This Linear Layout, despite seeming very simplistic, has caused me numerous headaches. How can something that seems so simple, be such a royal pain to grasp?
<?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"
android:background="#FF0000">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:layout_gravity="bottom"
android:background="#FFF"
/>
</LinearLayout>
A LinearLayout set to vertical orientation will ignore all layout_gravity parameters that refers to vertical alignment. So for example "bottom" wont work but "center-horizontal" will work. (The vertical alignment is always done so that each view in the layout i placed under the other views in the layout.)
A relative layout might be the way to go or maybe you can use this code that probably is pretty close to what you want.
<?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"
android:background="#FF0000"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:gravity="bottom"
android:layout_weight="1.0"
android:background="#FFF" />
</LinearLayout>
Edit This blog explains things further.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FF0000">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:layout_alignParentBottom="true"
android:background="#FFF"
/>
</RelativeLayout>
you can use relative layout were you can align bottom easily
If that is the simplicity of your layout, you shouldn't wrap it in a LinearLayout at all.
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#FFF"
android:text="HELLO HELLO" />
If you need to wrap it though, remove the vertical orientation:
<?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:background="#FF0000" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#FFF"
android:text="HELLO HELLO" />
</LinearLayout>
I think this code do what you want:
<?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"
android:gravity="bottom"
android:background="#FF0000">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:background="#FFF"
/>
</LinearLayout>
And if you want the textview on center, you can use:
<?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"
android:gravity="bottom"
android:background="#FF0000">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello"
android:layout_gravity="center"
android:background="#FFF"
/>
</LinearLayout>
Hope this help you.
I am using this XML to show my one Button at the bottom and one TextView at the top with one TextView right in the middle. The middle textview covers the whole span in between the button and the top textview. The middle TextView is not being displayed at all. What is wrong?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/task"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
/>
<Button
android:id="#+id/btnAddTask"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/AddTasks"
android:layout_alignParentBottom="true"
/>
<TextView
android:id="#+id/TasksList"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
android:layout_above="#id/task"
android:layout_below="#id/btnAddTask"
/>
</RelativeLayout>
Your problem is definitely that you have the TasksList TextView below your button. Swap your layout_above and layout_below values. This works for me:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/task"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
/>
<Button
android:id="#+id/btnAddTask"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/AddTasks"
android:layout_alignParentBottom="true"
/>
<TextView
android:id="#+id/TasksList"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
android:layout_above="#id/btnAddTask"
android:layout_below="#id/task"
/>
</RelativeLayout>
The problem wsa that you reversed your layout above and the layout below:
try
android:layout_below="#id/task"
android:layout_above="#id/btnAddTask"
See screenshot.
And here is the complete layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/task"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
/>
<Button
android:id="#+id/btnAddTask"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/AddTasks"
android:layout_alignParentBottom="true"
/>
<TextView
android:id="#+id/TasksList"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/tasks"
android:layout_below="#id/task"
android:layout_above="#id/btnAddTask"
/>
</RelativeLayout>
There's definitely something wrong with how you have this laid out.
You have for the button, alignParentBottom="true"... then for the TasksList TextView it is set to be below the button... basically off the screen.
You can remove orientation from the RelativeLayout... Relative layout's do not have orientation like LinearLayout's do.
As you're describing... I'm not 100% you can do it with a Relative Layout. If you simply wanted one thing on top, one centered and the other on bottom, it would be best to use a single layout parameter for each one, centerInParent, alignParentTop and alignParentBottom.
If you reconsider LinearLayout (as I'm guessing you started with) you'd stick with a Vertical Orientation, then give them layout_weight of 0, 1, and 0 making sure the height was set to wrap_content.
