I have been having trouble getting this LinearLayout to move to the vertical center of the RelativeLayout which is it's parent. I have tried many methods and maybe I am using the wrong one but I am not sure. Can someone just check it over to see what I need to add. Thanks. There is some TextViews to the right of the LinearLayout but I didn't include them as you don't require them but just remember the layout needs to be in the vertical center of the RelativeLayout and not in the complete center.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_card"
android:orientation="horizontal"
android:padding="5dip" >
<!-- ListRow Left sied Thumbnail image -->
<LinearLayout android:id="#+id/thumbnail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dip"
android:layout_alignParentLeft="true"
android:gravity="center"
android:background="#drawable/image_bg"
android:layout_marginRight="5dip">
<ImageView
android:id="#+id/list_image"
android:layout_width="50dip"
android:layout_height="50dip"
android:src="#drawable/thumb"/>
</LinearLayout>
If you need to center vertically a element inside a RelativeLayout, in your particular case the LinearLayout, then add android:layout_centerVertical="true" attribute to the LinearLayout.
first of all using linear inside relative is not a good idea, i prefer u change that but still if u wanna keep it same, cannot move linear layout in middel, u have to move ur image
now there are many ways such as
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
plus you can give margin -inputs manually
android:layout_marginTop="162dp"
android:layout_marginleft="80dp"..
try these first, but still strongly recommend to use either Linear or Relative and u can always drag ur UI's in design view.

I have a layout contain one image and 3 text field
I've tried to align the image to right and text field to left but I've failed
I've used
android:layout_gravity="right" for image and left to text but it did not work also I've used end and start in gravity with no success
this is the layout code:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">

android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:layout_marginBottom="2dp"
android:orientation="vertical"

<TextView

android:textSize="11dp"/>
</LinearLayout>
</FrameLayout>
Try to use a <RelativeLayout> instead of a <LinearLayout>
With the RelativeLayout you could place a widget depending on the position of another widget
Here the Relative Layout description
Hope this will help, I have not had time to test....
One linear layout should have vertical orientation and contain the 3 text fields.
One linear layout should have horizontal orientation and contain both the above linear layout and the image.
To push two views to the edges of the screen, you can also give each a left/right margin and then put a blank view with weight = 1 in between them.
Please read a bit more on how layouts work on Android and the different types available to you. A LinearLayout will stack the containing Views either Horizontally or Vertically one after the other. A FrameLayout is simply a container and the items within have to position themselves. RelativeLayout allow you to position your views with a relative reference to other views (in your case, you can position your ImageView, and then your 3 TextViews relative to where the ImageView is).
If you can use LinearLayout instead of RelativeLayout, you should do so, as RelativeLayout is always slower, due to having to perform two passes prior to rendering as it needs to measure each view and then also perform the layouts based on that. You might be looking for something like (pseudo-code):
<LinearLayout orientation=horizontal>
<LinearLayout orientation=vertical>
<TextView />
<TextView />
<TextView />
</LinearLayout>
<ImageView />
</LinearLayout>
You have not described your question well . Check below code if it works .
You just forgot to add orientation in linear layout containing one text view and a Image view .
Add Orientation to Your Linear Layout.
I am designing this layout in my android xml file
I am putting 2 linear layout 1 for the header and other for the body. so far all good. In the header liner layout i added the background image which comes perfectly fine.
Now when i am adding the right most image button for search and information, i want them to float through the header linear layout exactly as shown above. But the problem is if i put them into header linerlayout the width of the liner layout increases and both of them comes under the header layout. Is there anyway i can achieve this?
Thanks
try this combination:
<AbsoluteLayout
android:id="#+id/widget68"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_x="40px"
android:layout_y="35px"
>
<ImageView
android:src = "#drawable/androidlogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<Button
android:layout_width="124px"
android:layout_height="wrap_content"
android:text="Print Picture"
/>
</FrameLayout>
</AbsoluteLayout>
to get this:
You may also move your picture (button in this case) by padding it
So it's possible to align the top, bottom, left, and right of one view with another so that their edges are flush with each other. However, I've been wondering if it's possible to align the centers of two views of different sizes. My situation occurs when I have an ImageView side by side with a TextView, like this: [ImageView] [TextView]. The ImageView is bit taller than the TextView and so what I do is add padding/margins to the bottom of TextView to get it align and look like the ImageView and TextView horizontal centers are aligned. Problem is, when this view is displayed on larger tablet screens, the padding and margins don't work out right and the TextView doesn't look aligned with the ImageView. I'm sure there is an easy fix to allow this to always work out, so could someone provide me with some insights? Thanks!
This is how I did for a listview row:
<?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="#FFFFFF"
android:padding="5dp"
android:gravity="center_vertical">
<TextView android:id="#+id/questionItemTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="20sp"
android:textColor="#000000"
android:gravity="center_vertical"/>
<ImageView android:id="#+id/questionViewed"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/eye"
android:layout_marginLeft="5dp" />
<ImageView android:id="#+id/questionAnswered"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/check"
android:layout_marginLeft="5dp" />
</LinearLayout>
Use weightSum rather than padding in dips or pxs, that will make your layout look fine regardless of the size of the user's device.
or you could use gravity as well.
Or you can create a second xml file and insert that one into your res/xlarge file, the phone will pick which xml to read.
Why does FOOBARZ get layed out all the way at the bottom when no elements are layout_height="fill_parent" in other words, all elements are wrap_content for height?

From the RelativeLayout doc:
Class Overview
A Layout where the positions of the children can be described in relation to each other or to the parent.
Note that you cannot have a circular dependency between the size of the RelativeLayout and the position of its children. For example, you cannot have a RelativeLayout whose height is set to WRAP_CONTENT and a child set to ALIGN_PARENT_BOTTOM
Class documentation
Which is exactly your case. RelativeLayout can not do that.
For those looking for a solution to this, like I did, you can use FrameLayout instead of RelativeLayout.
Then you can set the gravity the intended object to bottom right as below
<TextView
android:layout_gravity="bottom|right"
android:text="FOOBARZ"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
</TextView>
You have set the RelativeLayout to "wrap_content"
and the TextView to android:layout_alignParentBottom="true", so it automatically tries to stretch the RelativeLayout to the bottom. Don't use such dependencies with Relative Layout, as it can count as "circular dependencies".
From the docs for RelativeLayout:
Note that you cannot have a circular dependency between the size of the RelativeLayout and the position of its children. For example, you cannot have a
RelativeLayout whose height is set to WRAP_CONTENT and a child set to ALIGN_PARENT_BOTTOM.
Try to align your TextView to something other than the parent RelativeLayout, but watch out for this problem as well:
Circular dependencies, need some help with exact code
Alternatively, try to add more sophisticated inner layouts.
Dont use alight_Parent type properties with the child views
You can use frame layout instead of RelativeLayout with respective gravity
<FrameLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content">
<TextView
android:layout_gravity="bottom|right"
android:text="Hello "
android:layout_height="wrap_content"
android:layout_width="wrap_content">
</TextView>
</FrameLayout>
FrameLayout is usually good for placing different views one on top of each other (where the most recent child is on top of the previous child). In your case, you'd like to place views one next to each other (above, below, start, end), so I think ConstrainLayout fits better because it's exactly what it does.
Unlike RelativeLayout, you'd be able to set the ConstrainLayout width to wrap_content and still arrange its children views as you wish, for example instead of
android:layout_alignParentTop="true"
you can use
grid:layout_constraintTop_toTopOf="parent"
and instead of
android:layout_alignParentBottom="true"
you can use
grid:layout_constraintBottom_toBottomOf="parent"
Good answers. Now if you don't have layout_alignParentBottom="true" and still getting this issue watch out for android:background="#drawable/bkgnd" where bkgnd is a biggie.
I'm not sure why the clean and obvious way of accomplishing this hasn't been posted yet. This performant solution works for any View MyView with a known height.
Wrap your RelativeLayout with height wrap_content in a FrameLayout:
<!-- width here should constrain RelativeLayout -->
<FrameLayout
android:layout_width="#dimen/my_layout_width"
android:layout_height="wrap_content">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<MyView
...
android:layout_gravity="bottom" />
</FrameLayout>
Just note that the view at the bottom of the FrameLayout will be on top of your RelativeLayout content, so you'll need to add padding to the bottom of that layout to accomodate it. If you want that view to be variable height, you can either Subclass FrameLayout to add padding in code based on the measured view height, or just change the FrameLayout to vertical LinearLayout if you're not worried about the performance, i.e. it's not a listview item, or the views are relatively lightweight.
Not sure why all the answers here suggest FrameLayout, which is designed to render a single view or views layered in the z axis. OP's problem is a sequence of views stacked vertically, which should be in a LinearLayout.
How can i put textview with id="naslov" to the center? I also tried with layout_gravity="center" but that doesn't work either.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/naslov"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20dip"
android:text="Povzetek"
android:gravity="center"/>
<TextView
android:id="#+id/aha"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="10dip"
android:text="Vseh oddaj:"
android:layout_below="#id/naslov"/>
</RelativeLayout>
android:layout_centerHorizontal="true"
android:layout_centerHorizontal="true"
there is also
android:layout_centerInParent="true"
Full list for RelativeLayout attributes is here
Also you can tell your TextView to fill_parent and then set gravity=center on it. So it'll center actual text within textView.
Supplemental Answer
As a more general answer to this question, layout_gravity does not work with the subviews of a RelativeLayout. It is for use with a LinearLayout or FrameLayout. However, the subviews of a RelativeLayout can still use gravity as usual because this is just how a view arranges its own content.
See the comparison in the following image. The green and blue views are TextViews inside of a RelativeLayout.
The gravity works but layout_gravity doesn't. See my fuller answer for more details.

Positioning views within a RelativeLayout
Relative Layout does not make use of layout_gravity, however you use gravity values in following ways : center, left , left|center , right|center , right, top, bottom.
<!-- below widget displaying text in left center -->
<TextView
android:id="#+id/song_title"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="sample name text"
android:gravity="left|center"
android:textSize="15sp" />
