I have a relative layout, and inside it i place 3 items, 2 imageviews and one scrollview.
My layout is like this...
<?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:src="#drawable/icon1" />
<TextView
android:id="#+id/hotelBtnDescTxtVw"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"

</LinearLayout>
The above code produces the view shown here:
You may note that the arrows are not aligned in the center, but are slightly moved to the right. Why is that, and how can I fix it ? Note that i have already used android:layout_centerHorizontal="true" to my imageviews.
Thank you in advance
Its problem with your
android:layout_margin="8dp"
remove it from both scrollview and imageView
and pass it to RelativeLayout direct.
or add
android:layout_marginTop="8dip"
android:layout_marginBottom="8dip"
in your RelativeLayout.
and pass
android:layout_centerHorizontal="true"
to your scrollview
they are aligned to the center if you put the marginRight into consideration, try adding android:layout_margin="8dp" to the arrows.
u need to set image view that is under the Relative layout set this image view width fill parent.
Try removing android:layout_weight="1" from your RelativeLayout and see if it works.
In your LinearLayout, the attribute android:orientation="horizontal" causing your display to be aligned horizontaly. Therefore your RelativeLayout is in center but since its shared with another layout thats why you cant note the difference. If you completely remove the first RelativeLayout (the one with id logosLayout) then i hope you'll see the second layout in center.
So, first you need to define the hierarchy of layout you require and then adjust your views accordingly.
It seems problem with your android:layout_margin="8dp" for your scrollview only and pass it to RelativeLayout direct but instead of using margin use padding = "8dp".

I m Not Sure But Remove Relative Layout And Use Linear Layout Its More Better Than Relative
The two textViews that you have in your layout use android:layout_width="wrap_content".
Use android:layout_width="match_parent" in the one you want to fill the screen.
every children relative layout in your xml has height and width as match_parent. Do you need it? Because if first layout have height as match_arent than it will not leave space for others. Try using "wrap_content" as height for inner relative layouts.
If I got your question, you have to set the width of the textview as
android:layout_width="match_parent"
But in my opinion, the hole screen is wrong. Use a LinearLayout (vertical or horizontal) and place there your first two textviews. And if you want more accuracy use the gravity feature in each text view and of course set a layout_weight for each TextView and weightSum in the LinearLayout.
I have TextView and ImageButton in xml layout. And ImageButton is positioned right of TextView and I want group both to center them horizontally at screen. I use RelativeLayout.
What should I do?
I assume you are developing an android application... If so this code can be used:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:orientation="horizontal">
<TextView
android:id="#+id/headerText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world"
/>
<ImageButton
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:src="#drawable/ic_launcher" />
</LinearLayout>
</RelativeLayout>
android:layout_centerInParent="true" will place items in the middle of the RelativeLayout parent
android:layout_centerHorizontal="true" will only center items horizontally. You can remove the one you don't need.
An optimized approach, which doesn't use unnecessary layout nesting and reduces the View counts by incorporating the image inside the TextView:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent"
>
<TextView
android:id="#+id/headerText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:drawableRight="#drawable/ic_launcher"
android:text="#string/hello_world"
/>
</RelativeLayout>
The secret is the use of the compund drawable android:drawableRight="#drawable/ic_launcher".
To change it programmatically, use setCompoundDrawablesWithIntrinsicBounds()
I don't know how to align 3 elements side by side. I would like to have :
One view with a thin width on the left
One linearLayout with text content on the middle
One imageView always on the right
Like this :
And today, i got this :
Here is my 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"
android:background="#color/gris_clair"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="#color/blanc" >
<View
android:id="#+id/view1"
android:layout_width="7dp"
android:layout_height="90dp"
android:background="#color/green_normal" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>
<ImageView
android:id="#+id/imageView1"
android:layout_width="80dp"
android:layout_height="90dp"
android:layout_gravity="right"
android:scaleType="centerCrop"
android:src="#drawable/test2" />
</LinearLayout>
</LinearLayout>
You can simplify your layout by setting the root LinearLayout to a horizontal orientation:
<?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="wrap_content"
android:background="#color/gris_clair"
android:layout_margin="5dp"
android:orientation="horizontal" >
<View
android:id="#+id/view1"
android:layout_width="7dp"
android:layout_height="match_parent"
android:background="#color/green_normal" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="TextView" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="80dp"
android:layout_height="90dp"
android:layout_gravity="right"
android:scaleType="centerCrop"
android:src="#drawable/test2" />
</LinearLayout>
You may want to tweak the colors or sizes to fit your desired end result.
I set the parent View's height to wrap the content, first two Views to match the parent view's height and the image to your size. This means that your image will decide the parent View's height.
If you want to evenly space/scale the views horizontally on your screen and use up all the space they have available you should look at the android:layout_weight attribute. You would set android:layout_width="0dp" for each View you want to scale with screen size and add android:layout_weight="x" where x is a number.
The number you choose will depend on how you want to divide up the available space each View will use. As an example if you wanted one View to use 1/3rd of the available space with a second using 2/3rds then set the first to 1 and the second to 2. 1+2=3 so 1 of a total 3 units and 2 of a total 3 units.
For your textview use weight to fill up space:
<TextView
android:id="#+id/textView1"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="TextView" />
You can use relative layout for that. and for the image view add alignparentright rule.
<RelativeLayout >
<View />
<LinearLayout/>
</LinearLayout>
<ImageView
android:alignParentRight="true" />
</RelativeLayout>
or use the weight for linearlayout, put 1 for textview and rest 0.
You can easy solve this problem using weight in LinearLayout, or make your parent RelativeLayout and place middle layout toLeftOf your left view and toRightOf your right view.
You can use relative Layout instead of linear layout to design custom design of your page.

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>
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.
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"

<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:text="#string/confirm_mobile_no_continue"
android:textColor="#color/white"
android:textStyle="bold"
android:translateY="-16dp" />
</RelativeLayout>
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)
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>
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.
Well this is 2022, but if you still are not using ConstraintLayout for some reason, like the one legacy project code I am fixing, use this property for a Bottom margin type visual.
android:translationY="-8dp"
and your code should look like this (in my case this a FAB in Relative Layout)
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
android:id="#+id/cart_check_out_btn"
style="#style/FABThemeDark"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginHorizontal="16dp"
android:layout_marginVertical="16dp"
android:text="#string/cart_check_out_btn"
android:textAllCaps="false"
android:translationY="-8dp" />
And it will work like this
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.
<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.
How do I stop my view from filling the entire screen and not showing my buttons at the bottom of the screen?
<?xml version="1.0" encoding="utf-8"?>

When I change my code and put the buttons at the top, it works fine. I have tried relative layouts, linear layouts, lauout weights, ...
What am I doing wrong?
RelativeLayout can be tricky to work with. I try to stick with FrameLayout and LinearLayout. Here is a sketch of the layout I would use in your case:
<LinearLayout orientation="vertical">
<ImageZoomView layout_weight="1" layout_height="wrap_content">
<LinearLayout orientation="horizontal" layout_height="wrap_content">
... buttons ...
</LinearLayout>
</LinearLayout>
Heights and widths are fill_parent when not mentioned. The layout_weight attribute on the ImageZoomView will cause it to expand as far as it can without squishing your bottom buttons.
Instead of putting android:layout_below in your LinearLayout. Try removing that and put
android:layout_above="#+id/myLinearLayout"
inside your ImageZoomView. Of course giving your LinearLayout the same id.
Perhaps the layout_weight is causing issues? Also it doesn't seem like you're give the items an object to be positioned relative to?
Change this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
to this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
