I suddenly have the problem that Scrollview extends beyond the bottom of the screen so that even if you scroll all the way down it does not show all its content. The XML is:
<?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:background="#FFFFFFFF">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="15dp"
android:background="#FFBBBBBB"
android:orientation="vertical" >
<View
android:layout_width="100dp"
android:layout_height="300dp"
android:layout_margin="15dp"
android:layout_gravity="center_horizontal"
android:background="#FFDDDDFF"/>
<View
android:layout_width="100dp"
android:layout_height="300dp"
android:layout_margin="15dp"
android:layout_gravity="center_horizontal"
android:background="#FFDDDDFF"/>
</LinearLayout>
</ScrollView>
It doesn't get any simpler than that. Once you have scrolled all the way down (as indicated by the shape of the scroller) you should see the bottom white margin but instead this is what it looks like:
Compare with the top:
The bottom should look like the top, only reversed. This happens in the emulator, on real devices and in pretty much every Android version I have tried. I am at a loss as to what I am doing wrong (if anything...).
Please no guesses and no shooting from the hip! Only tested answers. I wasted enough time on this already as it is. Thanks.
After wasting much time in dead alleys I was finally put on the right track by this other SO thread: the issue was the layout margin on the LinearLayout. Apparently ScrollView doesn't like that, just as it doesn't like its child to be centered (an issue flagged by many other people but not my problem here) and who knows what else. Very choosy widget. It's issues like this that make me reconsider my commitment to Android: it's just too time-consuming relative to alternative platforms and, even if you enjoy the challenge, time is money.
Anyway, for the benefit of those who will flop here later, here is a side-by-side demonstration of a broken layout (a simpler version of the one above) on the left and a working one on the right. The trick is to emulate the verboten margin with padding on an extra container.

try putting a padding on the bottom of the scroll view, so that you see a white line at the bottom - your view indeed does scroll all the way down , i tried it with this code and the result is this:
<?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:background="#FFFFFFFF"
android:padding="5dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="15dp"
android:background="#FFBBBBBB"
android:orientation="vertical" >
<View
android:layout_width="100dp"
android:layout_height="1500dp"
android:layout_gravity="center_horizontal"
android:layout_margin="15dp"
android:background="#FFDDDDFF" />
<View
android:layout_width="100dp"
android:layout_height="300dp"
android:layout_gravity="center_horizontal"
android:layout_margin="15dp"
android:background="#FFDDDDFF" />
<View
android:layout_width="100dp"
android:layout_height="10dp"
android:layout_gravity="center_horizontal"
android:layout_margin="15dp"
android:background="#FF00FF00" />
</LinearLayout>
Just try putting the LinearLayout inside another one
Like this:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFFFF">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="15dp"
android:background="#FFBBBBBB"
android:orientation="vertical">
<View
android:layout_width="100dp"
android:layout_height="300dp"
android:layout_gravity="center_horizontal"
android:layout_margin="15dp"
android:background="#FFDDDDFF" />
<View
android:layout_width="100dp"
android:layout_height="300dp"
android:layout_gravity="center_horizontal"
android:layout_margin="15dp"
android:background="#FFDDDDFF" />
</LinearLayout>
</LinearLayout>
</ScrollView>

Even in design view it starts somewhere in the middle and I can't scroll up, I can only scroll down. Similiarly when I run the app it shows the content somewhere in the middle and I can only scroll down, seems like the highest point is where I start. I don't know if it's a problem with margins or something else

Frame layouts repeat 32 times.
Solved by removing android:layout_gravity="center" from GridLayout.
I want to have a "fixed_space" at the top of screen and a "scrollview" at the bottom of the screen which should be below fixed_space. The rest of the screen is a container "rest_space".
Unfortunately my scrollview has a shorter height(by 100dp which fixed_space has) ,if content is too big/scrollable.
I tried to achieve same with ConstraintLayout and RelativeLayout, but I have got same result.
Any ideas why scrollview has 100dp shorter height, as it should be?
EDIT: Scrollview should take as much space as she needs.

Ok, I think this should solve your probem:
First, I started by using RelativeLayout. I did it in order to get the fixed_space aligned to the top and the scrollview aligned to the bottom.
Then I changed the View for a LinearLayout and put a TextView within it so I could use wrap_content and this is the tricky part:
When you use ScrollView with wrap_content and a View with the weight stuff, Android can't make the calculations it needs to get the screen drawed because there is no reference. When I put the TextView with wrap_content itself that gives the reference because Android know the size of the text.
You don't have to use the TextView but you will need anything that gives Android that reference.
In this case, the scrollview is going to be stretched, not the LinearLayout. If you want the second to get strached, then I'm afraid you are going to need to set a fixed height to your scrollview.

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" >

android:layout_height="wrap_content"
android:layout_gravity="center"
android:fillViewport="true">

<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 novice in Android trying to make this layout:
Simply what I want to achieve:
The red container should take as much space as it needs but not as much that green container have to be shrinked. If there are too many items, red container will be scrollable. Green container is also always centered in orange one if there is space for it (if not it is actually still centered).
I don't know how to do it at all :( . Here is my try:
The problem is that I want to always maintain height of green container (minHeight does not work I can't understand why) and make the green container centered in orange one. I have problem with Scenario 2 (as you can see in the picture), this code works good in first scenario.
<LinearLayout 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"
android:orientation="vertical">
<ScrollView
android:id="#+id/red_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/holo_red_dark"
android:scrollbarAlwaysDrawVerticalTrack="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Items are here -->
</LinearLayout>
</ScrollView>
<LinearLayout
android:id="#+id/orange_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/holo_orange_dark"
android:gravity="center"
android:orientation="vertical">
<LinearLayout
android:id="#+id/green_container"
android:layout_width="100dp"
android:background="#android:color/holo_green_dark"
android:layout_height="50dp"
android:orientation="horizontal">
<!-- My content -->
</LinearLayout>
</LinearLayout>
</LinearLayout>
Edit: minHeight does not help:
Edit: image for user Illegal Argument:
Try setting property android:minHeight = "(whatever)dp" to orangeContainer. This worked for me in others "similiar" cases.
:)
Is this what you are looking for:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

android:background="#android:color/background_dark" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
<LinearLayout
android:id="#+id/list_items"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:background="#android:color/darker_gray"
android:gravity="center"
android:minHeight="200dp"
android:orientation="vertical" >
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>
</RelativeLayout>
Snapshot in ecllipse:
I haven't been able to find a similar problem to the one I'm having on StackOverflow - basically, I have a simple XML layout with a vertical LinerLayout which uses layout_weight to make a 10/50/40 split, which is what I want (as seen below):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="left"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight=".1"
android:text="#string/title"
android:textColor="#color/black"
android:textStyle="bold" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight=".5"
android:orientation="vertical"
android:background="#color/green">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="top"
android:fillViewport="true">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" />
</HorizontalScrollView>
<ImageView
android:id="#+id/preview_bg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/level_preview_back"
android:focusable="false" />
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight=".4"
android:text="#string/title"
android:textColor="#color/black"
android:textStyle="bold" />
</LinearLayout>
BUT - I want the HorizontalScrollView and the ImageView to be overlayed (i.e. take up the exact same space on on top of the other), so I insert a RelativeLayout as such:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="left"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight=".1"
android:text="#string/title"
android:textColor="#color/black"
android:textStyle="bold" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight=".5"
android:orientation="vertical"
android:background="#color/green">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="top"
android:fillViewport="true">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" />
</HorizontalScrollView>
<ImageView
android:id="#+id/preview_bg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/level_preview_back"
android:focusable="false" />
</RelativeLayout>
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight=".4"
android:text="#string/title"
android:textColor="#color/black"
android:textStyle="bold" />
</LinearLayout>
But when I do this, the layout_weight (10/50/40 split) breaks and suddently the LinearLayout that now contains the RelativeLayout takes up virtually all the screen in the previews.
Anyone experienced this problem or know a good workaround? I've also tried replacing the LinearLayout with the RelativeLayout directly and I have the same problem.
EDIT: Looking further into this issue, there seems to be more to it. As I commented below, I was able to get around the problem by wrapping LinearLayouts around the TextViews, though I'm not sure why that worked. Updating my SDK and plugin didn't help (though I did need to do it....)
Moving further along with my task, I hit a second problem - I was implementing a second version of the overlapped ScrollView & ImageView (which were done with a FrameLayout as suggested by Karsten) but the layout_weight problems began anew.
Testing various arrangements, it seems that the issue is very much related to the image I'm using, which is quite large in resolution. Replacing them with a smaller image corrects the issues - it looks like using large images in either ImageViews or as backgrounds to LinearLayouts tends to ruin the layouts for the entire screen.
EDIT #2: I've actually loaded the XML on to two different devices and it renders exactly as it should.... This seems to be a bug with the Eclipse XML layout viewer?
(Please excuse the poor XML formatting - the Eclipse Android xml editor is frustrating in that regard...)
The XML you've posted works fine for me in the Eclipse preview. Are you running the latest version of the Android plugin?
Note that you can replace the middle LinearLayout and RelativeLayout with a single FrameLayout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="left"
android:orientation="vertical" >

android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight=".1"
android:text="string/title"
android:textStyle="bold" />
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight=".5"
android:background="#00ff00" >
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="top"
android:fillViewport="true" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" />
</HorizontalScrollView>
<ImageView
android:id="#+id/preview_bg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ff0000"
android:focusable="false" />
</FrameLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight=".4"
android:text="string/title2"
android:textStyle="bold" />
</LinearLayout>
