I must be doing this all wrong, and layouts confuse me, so I hope someone might guide me in the right direction. This whole thing is a mess because I've been fiddling with it non-stop since I created it a month ago, trying to fix little issues here and there, so I apologise quite a lot in advance for this disaster.
Literally all that I want is a LinearLayout where everything is centred horizontally and vertically.
This is how it shows up in my Design page.
Before I dump in my layout, allow me to explain what's going on.
I have a TextView that shows status messages above the ImageButton. Below the ImageButton, I have a TextSwitcher and finally a circular ProgressBar.
I've had to put android:adjustViewBounds="true" and android:scaleType="fitCenter" on my ImageButton because the image is much bigger than would fit, otherwise.
Anyway, here's the dump. Hoping someone might be able to make suggestions.

If you still like using LinearLayout, you can order your layout like this to have a layout center both horizontally and vertically
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#0ff"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="vertical" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Button Center Vertical/ Horizontal" />
</LinearLayout>
</LinearLayout>
Or simple use RelativeLayout with android:layout_centerInParent="true" to have a layout center both orientation
Hope this help
First of all, LinearLayout can either store everything horizontally or vertically but not both at the same time. So you have to choose specially what do you want. If you want everything to appear in vertical fashion but still some components, say TextView needed to be in a horizontal layout, you may wish to use another LinearLayout (nested inside the main LinearLayout and give it an orientation : Horizontal ).
Apart from this, I don't think there is any problem with that Layout or I did not understand your problem properly, either one.

I've been trying to recreate this layout in Android Studio (API 19) without success.
I added at the top part of the image what I need without texts on it, the part below has some explanations.
Every time I tried (no matter LinearLayout or GridLayout), the text in the middle broke the design if it is long or if I do not set real DP size (like using wrap_content), if the text has a fixed size I must adapt it to every screen size on both, vertical and horizontal, which I don't want, because I must update a lot of files it every time I make changes on layouts, and if it has wrap_content and the text is long the switch goes off of the screen.
I made this "design" with Photoshop of what I need to recreate on Android Studio on a layout (xml only, not programmatically), if possible I'd like LinearLayout or GridLayout or both, I don't care how much sub-layouts are needed.
Additional: If someone knows how to get that switch style for older versions of Android, it'd be really good to get the same style on that too, but is not necessary.
Please help me, I really can't make it, thanks a lot.
With a Relative Layout this kind of design wont be a problem.
You will need to use the properties android:layout_alignParentRight and android:layout_alignParentLeft.
Your center textview will use android:layout_toRightOf and ndroid:layout_toLeftOf.
More informations : Relative layout documentation
Use following XML as your layout codes, this is exactly what you want on your designs
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/image"
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/icon_paypal"
android:layout_margin="16dp"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/switchlayout"
android:layout_toRightOf="#+id/image"
android:layout_marginTop="16dp"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Text 1"
android:textColor="#000"
/>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Text 2"
android:textColor="#ccc"
/>
</LinearLayout>
<LinearLayout
android:id="#+id/switchlayout"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"

android:paddingLeft="16dp"
android:gravity="center"
android:layout_height="72dp">
<Switch
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
Use Follow XML code. it will fit in any screen
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_weight="1"
android:orientation="horizontal">

android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight=".2"
android:gravity="center">
<ImageView

android:layout_height="wrap_content"
android:src="#drawable/app_icon" />
</LinearLayout>
<LinearLayout

I have a hard time pointing out what UI elements are used here? Is it buttons or listviews?
This view is not seems as a list view. They are either Buttons or ImageButtons fitted in some layout.
If you want to make this in a ListView, you are gonna have a hard time. The best would be to make it in a GridLayout, if you are not that confident in working with that then the easiest solution would be a LinearLayout in the root with vertical orientation, and then add a LinearLayout with horizontal orientation where the childs have `weight="1"
Something like this (Just for the first two buttons):
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="20dp">
<FrameLayout
android:layout_width="0dp"
android:layout_height="50dp"
android:layout_weight="1"
android:clickable="true"
android:layout_marginRight="10dp"
android:onClick="onChildOneClick">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Button 1"
android:background="android:color/green" />
</FrameLayout>
<FrameLayout
android:layout_width="0dp"
android:layout_height="50dp"
android:layout_weight="1"
android:clickable="true"
android:layout_marginLeft="10dp"
android:onClick="onChildTwoClick" />
</LinearLayout>
</LinearLayout>
Inside your framelayout you can put a ImageView + TextView to make it look like the sketch
My main Activity has a number of buttons, that fit below each other on a large Tablet screen, but not on a smaller Phone screen. I added a ScrollView, so that the user can scroll down to the other buttons if the screen size requires it:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/bg"
android:gravity="center_horizontal">
<TextView
android:id="#+id/trackSelectorText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"/>
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center_horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="foo" />
<!-- More buttons -->
</LinearLayout>
</ScrollView>
</LinearLayout>
This kinda works, however I have a large blank space below the last button (i.e. the ScrollView can scroll down too far). Both on an actual Tablet and on the emulator with a Phone configuration. If I center the inner LinearLayout (instead of center_horizontal), the space is evenly spread between the top and the bottom, which I don't want neither. How do I fix this layout?
I hope this image makes it more clear, imagine that the ScrollView has been completely scrolled down and showing the last buttons. The blank space I mean is the one below Button 6 on the right image:
Try adding this attribute to your ScrollView element.
android:fillViewport="true"
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:fillViewport="true" > ... </ScrollVIew>
Ref: ScrollView Ref
Actually, it wasn't really related to the layout (unless I'm missing something). I tried commenting out the background attributed, and it suddenly worked. The background imaged (#drawable/bg) was simply too big and caused the scrolling. I converted the background into a 9-patch image, so it could be scaled automatically, and voilà, the additional space was gone.
Still, if this would've been achievable without 9-patch, I'd still be interested to hear if this can be done in the XML file.
you can use this attribute in scrollview to avoid extra padding at bottom of view
android:overScrollMode="never"
I have checked with my code..Work perfectly:
<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/bg"
android:gravity="center_horizontal">
<TextView
android:id="#+id/trackSelectorText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"/>
<ScrollView

android:layout_height="match_parent"
android:layout_gravity="center">

May be Help you.......!!
I'm trying to make a simple clock/stopwatch app. In my overall vertical linear layout, I have a relative layout followed by a button. The relative layout has several imageviews stacked on each other in order to produce the clock.
I noticed, however, that the relative layout, as well as the imageviews themselves, take up way too much space in the linear layout. The clock pieces are SQUARE, so why is Eclipse insisting that it is a long vertical rectangle? My button at the bottom doesn't even show if I don't use weights. (But strangely enough, it shows if it is above the relative layout.)
I've tried everything I could: Set the height of items in relative layout to wrap_content, as well as the relative layout itself. I tried using weights, by giving the relativelayout a weight of 0 and the button 1, and then setting their layout_heights respectively to 0dp as needed. Still no go. There is a lot of room left for other things, and I'd like for the clock's parent layout to wrap itself around just the content.
What is going on here? Please see attached image for details. Code is attached below.
<LinearLayout 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"
android:background="#drawable/tiling_rules"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:ignore="ContentDescription" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/clock" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/hour" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/min" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/sec" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/bell" />
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_gravity="center_horizontal"
android:layout_weight="1"
android:text="Test" />
It turns out that all I needed was to add:
android:adjustViewBounds="true"
to every ImageView! Now the clock pieces' bounds are "wrapped" around the content, even though setting wrap_content in its layout didn't work. Thanks for the suggestions though!
Try using a RelativeLayout as your main layout. This way you can make the button show at the bottom of the screen. Then if you need, use a separate layout for the clock pieces within the main layout
Kinda like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="ContentDescription" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/clock" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/hour" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/min" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/sec" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/bell" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:text="Button" />
I wish to keep a button at the bottom of my Activity screen. It has to be fixed irrespective of the size of scrollview above it. The problem is that once the textviews of the scrollview take up some place, the height of my button keeps decreasing and it eventually gets pushed out of the activity screen. This is the layout I am using.
<?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:layout_height="wrap_content" android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" android:gravity="center"
android:text="Practice Exam" />
<ScrollView android:id="#+id/Scroll" android:layout_width="match_parent"

android:textSize="20sp" />
<TextView android:id="#+id/tvURL" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_marginBottom="30dp"
android:paddingTop="10dp" android:layout_gravity="center"
android:text="hello" android:textColor="#android:color/white"
android:typeface="sans" />
</LinearLayout>
</ScrollView>
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:gravity="bottom">
<Button android:id="#+id/btBottom" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1"
android:text="Enter" />
</RelativeLayout>
</LinearLayout>
I have also tried using android:weight=1 and android:layout_height=0dp in the Scrollview. But this removes the entire Scrollview portion from my activity and I can't see anything.
I do know that there are many similar questions asked about this and believe me, I have tried many of these. However, none of the tricks have worked for me. I have spent almost half a day fixing this. Kindly help.
For a case like this always use RelativeLayouts. A LinearLayout is not intended for such a usage.
Try this:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true">
<Button android:id="#+id/btBottom"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Enter"
android:layout_alignParentBottom="true"/>
<ScrollView
...
android:layout_above="#id/btnGetMoreResults"/>
</RelativeLayour>
You should try using RealativeLayout instead of Linear, and then you could use
android:layout_above="#+id/btBottom"
android:layout_alignParentBottom="true"
That should solve your problem.
looks like you need 'alignParentBottom' in your button like this
<Button android:id="#+id/btBottom"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Enter" />
Do not wrap Button to RelativeLayout
Set layout_height of ScrollView to 0dp
Add layout_weight of ScrollView to 1
For this it would probably be a good idea if you used RelativeLayout for the outer wrapper layout. Then you could just set the layout with the button inside to LinearLayout and set layout_alignParentButtom="true" while you set your #+id/Scroll to layout_alignParentTop="true"
Also, you should probably set the layout with the button inside´s height to wrap_content instead of fill_parent
Why do you use a LinearLayout at top level at all ?
Choose a RelativeLayout with fill/fill and the following three childern (no further nesting !):
1) TextView with android:layout_alignParentTop="true" and android:layout_centerHorizontal="true"
2) Button with android:layout_alignParentBottom="true" and android:layout_centerHorizontal="true"
3) ScrollView with android:layout_below=#id/textview_id and android:layout_above="#id/button_id"
I didn't test it though, but give it a try.
