I have a problem to fill the whole screen with a scrollview.
How do I make the scrollview cover the whole screen width and screenheight? I tried with fillviewport but that that works for the screenheight.
I am not sure if its the scrollview or its parent (FrameLayout) that is the problem?
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:fillViewport="true">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/img1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="img1"/>
<TextView
android:id="#+id/text_img1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
/>
<ImageView
android:id="#+id/img2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="img2"/>
<TextView
android:id="#+id/text_img2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
/>
<ImageView
android:id="#+id/img3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="img3"/>
<TextView
android:id="#+id/text_img3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
/>
</LinearLayout>
</ScrollView>
change your ScrollView and LinearLayout like this
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
Change your <ScrollView> from wrap_content to match_parent.
Example:
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center">
Also, you should be using match_parent instead of fill_parent in API 8+.
EDIT:
After talking a bit in the comments, OP and I discovered that the FrameLayout's default background is transparent, which means you can see the old view underneath.
Using a LinearLayout or really anything instead of a FrameLayout will fix this problem.
Other answers are going in the right direction but your main problem is probably due to the fact that it's a Dialog.
First of all make sure your Dialog is borderless. You can use one of approaches proposed here (not to duplicate answers).

I am creating an Android app which has a main RelativeLayout and some LinearLayout within it.
Now i have this problem. When dragging items to the editor, e.g. a LinearLayout, it doesn't fit to the full width of the screen. How can I make this possible? This is my XML:
<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"
android:fillViewport="true"
android:gravity="fill"
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=".MainActivity" >
<LinearLayout
android:id="#+id/itemDetailLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:orientation="vertical"
android:fillViewport="true" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="#+id/itemImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minHeight="40dp"
android:minWidth="40dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/itemName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:text="Name"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
android:fillViewport="true" >
<TextView
android:id="#+id/itemRecentHigh"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Recent High" />
<TextView
android:id="#+id/itemRecentLow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Recent Low" />
<TextView
android:id="#+id/itemAverage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Average" />
</LinearLayout>
</LinearLayout>
<LinearLayout
android:id="#+id/listViewLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/itemDetailLayout"
android:layout_marginTop="10dp"
android:fillViewport="true"
android:gravity="fill_horizontal"
android:orientation="vertical" >
<ListView
android:id="#+id/searchListView"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >
</ListView>
</LinearLayout>
Added a screenshot for more info. Added blue background to have some contrast.
Replace this:
android:layout_width="wrap_content"
android:layout_height="wrap_content"
With
android:layout_width="match_parent"
android:layout_height="wrap_content"
into your LinearLayout or Remove all the Padding from main RelativeLayout
Removing padding makes the linear layout fit the entire screen of the device
The space between the blue part and the "end of the screen". On the sides and above the part where the back button and home button are.
Remove the padding from the root RelativeLayout.
Try
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical>
// Other views within the linear layout
</LinearLayout>
I suppose you are using Eclipse. Personally, I hate the Graphical Editor of Eclipse and I usually write the XML code directly because working with the editor is a real pain
Don't use fill_parent as it is deprecated.
Instead to your RelativeLayout set
android:layout_width="fill_parent"
android:layout_height="fill_parent"
Then, to the list view that you want to fill the rest of the screen, you can set this tags
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"
By doing so, you are telling the XML that you want your ListView to do what fill_parent used to do in previous versions of Android.
Kind regards!
you should try something like the following :
<LinearLayout
android:id="#+id/itemDetailLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
...
</LinearLayout>
what i mean you should do this :
android:layout_width="fill_parent"
for every LinearLayout that you want its width to fill_parent .
FILL_PARENT means that the view wants to be as big as its parent as mentioned in the documentation .
and please give me some feedback
Hope That Helps .
I wan't to create a FragmentStatePagerAdapter for that my layouts need(need?) to be ScrollView at toplevel.
Now when I create my layout the LinearLayout ( or RelativeLayout doesn't matter ) never uses the full scrollview-container, even though I set layout_height and layoutg_width to "match_parent" ( fill_parent or wrap_content doesn't do the trick either )
Here is part of the layout
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/intro_scroll_view_1"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:orientation="vertical"
android:background="#drawable/intro_dummy">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=".80"
android:layout_gravity="center_horizontal">
<ImageView
android:layout_width="223dp"
android:layout_height="60dp"
android:id="#+id/imageView"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:src="#drawable/logo"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight=".20"
android:layout_gravity="center_horizontal">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/button">
</RelativeLayout>
<Button
android:background="#null"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Get Started"
android:id="#+id/button"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:textColor="#ffffff"
android:padding="2dp"/>
</RelativeLayout>
</LinearLayout>
</ScrollView>
Since I use match_parent it should use the whole screen? Nope it only uses a random bit of the screen
If I remove the Scrollview and just make the LinearLayout the toplevel-element it uses everything. So I am guessing I am missing something in the Scrollview description to make it use everything?
Use
android:fillViewport="true"
In your ScrollView, http://developer.android.com/reference/android/widget/ScrollView.html#attr_android:fillViewport
Defines whether the scrollview should stretch its content to fill the viewport.
I am developing an app which has a splash screen, you can see it in the picture below.
My problem is that I am needing to put a progress bar as you can see in the picture below without many layouts, because now I have eight layout in order to get this effect (layout-sw320dp, layout-sw320dp-land, layout-sw480dp, layout-sw480dp-land...600,720).
I was trying use relative layout and center horizontally the progress bar, but with different screen sizes the progress bar get other position vertically.
Could I solve it with less folders?
This is my layout file for 320dp:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/splash_screen_land"
android:orientation="vertical" >
<ProgressBar
android:id="#+id/progressBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="24dp" />
</RelativeLayout>
I suggest you use just one layout file, let's say splash.xml. Put in a RelativeLayout your ImageView, with android:layout_centerInParent="true". Then your ProgressBar with android:below="#id/image" to put it relatively below the image. You can change the layout paddingBottom to adjust views in the center of the layout.
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="#dimen/padding_bottom">
<ImageView
android:id="#id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/image"
android:minHeight="#dimen/progress_height"
android:minWidth="#dimen/progress_height" />
</RelativeLayout>
Now instead of having many layouts, you will keep the above layout, and create many values according to your screen sizes. Meaning :
values/dimens.xml
values-large/dimens.xml
values-land/dimens.xml
etc.
Thus, your view's layout won't change from a screen to another, only their size will !
Maybe 3 horizontal LinearLayout using layout_weight to center everything horizontaly with respect of the ratio, containing a vertical LinearLayout with centered gravity?
If you post your actual layout file, that could be easier to explain.
Edit:
Something like that: (you may have to play with the layout_weight values to get the size you want:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"></LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"></LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/splash_screen_land"/>
<ProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"></LinearLayout>
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"></LinearLayout>
</LinearLayout>
I could solve it with weightSum, layout_weight properties which are very useful to imitate percentages.
This is my code with the problem solved:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/splash_screen_land"
android:gravity="center_horizontal"
android:orientation="vertical" >
<android.support.v7.widget.Space
android:id="#+id/space1"
android:layout_weight="100"
android:layout_width="match_parent"
android:layout_height="0dp" />
<ProgressBar
android:id="#+id/progressBar1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="15" />
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="17"
android:gravity="center"
android:text="TextView"
android:textSize="20sp" />
</LinearLayout>
I hope this will be useful for someone else
Hey im having trouble with these linear layouts in android xml. initially i did them in a relative layout and it worked fine, but after some research i discovered that relative layouts inside of a scrollview doesnt work supposedly. so now after much tweaking my imageview shows up but has a huge margin above and below it and my textview doesnt even show up aside from being where its supposed to in the graphics editor but blank.
so whats wrong? should i even be using a linear layout?
this is roughly what its supposed to look like http://www.mediafire.com/view/?z945tz2vrb2x46t
and this is what it looks like after Abdul and Ralgha's help as well as setting the base linear layout's height to wrap content http://www.mediafire.com/view/?px17q2z3yyeo8az
Thanks

Don't worry about weight right now, leave it removed. In your TextView, change "android:src" to "android:text" (without the quotes naturally). If that alone doesn't solve it, remove the textSize line and see what happens. If that works, then you can start playing with sizes (and weights if needed).
Also, textSize should be given in sp rather than dp. sp is for text, dp is for everything else, though that's not what is causing your problem.

might be the cause of your problems
Its works like charm, Use the following coding to achieve your thing:
<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:gravity="center_vertical"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:fillViewport="true" >
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:orientation="vertical" >
<TextView
android:id="#+id/today"
android:src="#string/today"
android:textSize="30sp"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:text="#string/today"
/>
<ImageView
android:id="#+id/image1"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:contentDescription="#string/nissan"
android:src="#drawable/weeklylist_blocks" />
</LinearLayout>
</ScrollView>
</LinearLayout>
I want the content inside the scrollView as center.
<ScrollView
android:id="#+id/scroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="12dp"
android:paddingBottom="20dp"
android:scrollbarStyle="outsideOverlay"
android:layout_gravity="center" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="check"
android:gravity="center_vertical|center_horizontal"/>
</ScrollView>
Note: there is no android:gravity attribute for scrollvew.
any sol:-
I had the same issue and finally figured it out. This is for a vertical ScrollView.
Put your ScrollView inside a RelativeLayout and center it in the RelativeLayout. In order for this to work, your ScrollView should have
android:layout_height="wrap_content"
This is how the final code should look like:
<?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">
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="b1"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="b2"/>
<Button
android:id="#+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="b3"/>
</LinearLayout>
</ScrollView>
</RelativeLayout>
How about this?
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="12dp"
android:paddingBottom="20dp"
android:scrollbarStyle="outsideOverlay" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center"
android:gravity="center">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="check"
android:gravity="center_vertical|center_horizontal"/>
</LinearLayout>
</ScrollView>
I think a more elegant solution would be to use the ScrollView's android:fillViewport property. A ScrollView is a little different in how it treats it's content view (can only have one), even if you set match_parent (fill_parent) to the ScrollView it won't give that much spacing to it's content view, instead the default behavior is for the ScrollView to wrap the content regardless of what you specify for that view. What android:fillViewport does is tell the ScrollViewto stretch its content to fill the viewport (http://developer.android.com/reference/android/widget/ScrollView.html#attr_android:fillViewport). So in this case, your LinearLayout would be stretched to match the viewport and if the height goes behind the viewport then it will be scrollable which is exactly what you want!
The accepted answer won't work properly when the content extends beyond the ScrollView because it will still center the content view first causing it to cut off a portion of the view, and the ScrollView centered in another layout works but just doesn't feel right, besides I think it will also result in a lint error (useless parent or something along those lines).
Try something like this:
<ScrollView
android:id="#+id/scroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="12dp"
android:paddingBottom="20dp"
android:scrollbarStyle="outsideOverlay"
android:fillViewport="true">
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="check" />
</LinearLayout>
</ScrollView>
Just remember that the reason it is being centered here now is because of the android:gravity on the LinearLayout since the ScrollView will stretch the LinearLayout so keep that in mind depending on what you add to the layout.
Another good read on ScrollView although not about centering but about fillViewport is http://www.curious-creature.org/2010/08/15/scrollviews-handy-trick/
Use this attribute in ScrollView
android:fillViewport="true"
Example
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbarStyle="outsideOverlay"
android:fillViewport="true"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--Your Code goes here-->
</RelativeLayout>
</ScrollView>
Make sure to use Single Child in ScrollView just like in above example which is Relativelayout.
For #Patrick_Boss - what stopped the content from cutting of in my application was to change the gravity and layout_gravity to center_horizontal for the LinearLayout.
It worked for me...but not sure if it will work for you.
Modification of #Ghost's answer -
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="12dp"
android:paddingBottom="20dp"
android:scrollbarStyle="outsideOverlay" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="check"
android:gravity="center_vertical|center_horizontal"/>
</LinearLayout>
</ScrollView>
One thing to consider is what NOT to set. Make certain your child controls, especially EditText controls, do not have the RequestFocus property set.
This may be one of the last interpreted properties on the layout and it will override gravity settings on its parents (layout or ScrollView).
using the scroll view inside the ConstraintLayout. It is worked for me
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" />
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
Scroll view height should be wrap_content
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
