I've been struggling with this problem for awhile now. Basically, I've created a class that returns me a properly stylized GraphicalView chart; I have one class for bar charts and another for pie charts (I used renderer.setInScroll(true) BTW). I populate my Activity with a few charts and a few TextViews, but the more I add Views (any View) they are pushed off the top of the screen and there is a big empty space at the bottom of the scroll view.
My XML:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scrollingProfilePaid"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/paidLayoutLinearParent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="00dp"
android:orientation="vertical">
<TextView
android:id="#+id/totalScore"
android:layout_width="wrap_content"
android:layout_height="350dp"
android:layout_gravity="center"
style="#style/GameTextWhite"
/>
<LinearLayout
android:id="#+id/pastScoresChart"
android:layout_width="fill_parent"
android:layout_height="350dp"
android:orientation="vertical"/>
<TextView
android:id="#+id/totalTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
style="#style/GameTextWhite"
/>
<TextView
android:id="#+id/totalAverageResponseTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
style="#style/GameTextWhite"
/>
<LinearLayout
android:id="#+id/pastTimesChart"
android:layout_width="fill_parent"
android:layout_height="350dp"
android:orientation="vertical"/>
<!--...........-->
</LinearLayout>
</ScrollView>
What I've tried:
1.ScrollView->android:fillViewport="true"
2.Instead of specifying a height for the charts I set it in the java class using pastScoresChart.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, (int)(dens*350)));
3.Wrapping the ScrollView in a , using a child Relative Layout with android:alignParentTop="true" as the header, another child Relative Layout with android:alignParentBottom="true" as the footer, and changing the ScrollView to android:alignBelow="#id/header". This just made the Scrollview about 40px tall, seemingly making the problem worse.
4.Oodles of other things that I can't recall this second.
I've found a workaround of setting android:marginTop="500dp" (or a similarly large value) in the ScrollView will push the Views back down into their approximate respective positions. Unfortunately it is difficult to get it to fit exactly, and it worries me for device compatibliity. Any suggestions?
The empty space at the bottom of the ScrollView must be because of it's child (LinearLayout) attribute android:layout_gravity="center". Try to use like this:
<LinearLayout
android:id="#+id/paidLayoutLinearParent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
OBS 1: The android:layout_marginTop="00dp" attribute is unnecessary.
OBS 2: fill_parent is deprecated starting from API Level 8 and is replaced by match_parent. So, use match_parent. More on: http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html
OBS 3: Here is a tip about debugging layouts: change the background color of the views to see what are the bounds of each 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"

</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.
Please refer to example below. I want to have the top layout (below encased in red) to be unmoving in a scrollview in my activity. I have a scrollview as the parent layout and then I thought having a relative layout for the top one would work, and align it to the top, but that didn't really work out as it still remained within the scrollview. I would like to have the users have the red-layout box remain static when they scroll down.
I figure I would also have to put in a topMargin at the top of the scrollview or something in order to fit the redbox layout in.
XML Code posted here: http://pastebin.com/bxdREbeG
Do something like this (hand code, for reference only):
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="#+id/YourTopStaticView"
android:layout_width="match_parent"
android:layout_height="48dp"> //Or any other height you want
//Contents of the top view
</RelativeLyout>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/YourTopStaticView">
//Contents of the ScrollView
</ScrollView>
</RelativeLayout>
As a side note, do not hardcode children into the ScrollView like that. Use the RecyclerView (which is an updated, modern replacement for ListView), which you will be expected to know how to use if you want to move into serious Android programming. It is actually super easy to use, once you get the hang of it :-)
You should use the ScrollView with only one child (official documentation - http://developer.android.com/reference/android/widget/ScrollView.html). According to your xml, your ScrollView is very complicated with a lot of child widgets.
The best option for you is to use a LinearLayout as the root for the whole container, a LinearLayout( or Relative) for the top layout containing the Reset and Save buttons, and a ListView for the long list that you have. ListView takes care of it's own scrolling. So you don't have to worry about that.
This will improve your code performance as well.
This should suit your needs:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout android:id="#+id/topPanel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="5dp">
<TextView android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:text="Multi TTS Implementation"/>
<Button android:id="#+id/save"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:text="SAVE"/>
<Button android:id="#+id/resetAll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/save"
android:layout_centerVertical="true"
android:text="RESET ALL"/>
</RelativeLayout>
<ScrollView android:id="#id/scroll"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_below="#id/topPanel"
android:layout_alignParentBottom="true"
android:padding="5dp">
<!-- Your scrollable content here -->
</ScrollView>
</RelativeLayout>
My Current Implementation
I have a HorizontalScrollView which I create in XML that houses a few LinearLayout children. I have added this code below.
There are two LinearLayout containers with the id's group_one and group_two and these are populated programmatically at run time.
I also fix the width of the HorizontalScrollView at run time depending on the amount of View objects I will be inserting.
This solution works great for when the children fit in the HorizontalScrollView without the need to scroll.
The Issue
As soon as I need to scroll (there are more children than can be displayed within the fixed width HorizontalScrollView) then the scrollbar will not go all the way to the right, even though I can see that the child layout is of the correct width, and I can see the scrollbar just will not go any further.
My Question
Why would there be a limit on the scrollbar moving any further right?
My Code
HorizontalScrollView XML
<!-- THIS IS WHERE THE PLUGIN BUTTONS ARE HOUSED -->
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="horizontal"
android:id="#+id/map_plugin_scroll_view"
android:background="#color/map_plugin_background">
<!-- Enclosing box to layout the two groups.-->
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_margin="8dp"
android:id="#+id/group_container">
<!-- These layouts contain the map plugins. -->
<LinearLayout
android:id="#+id/group_one"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"/>
<LinearLayout
android:id="#+id/group_two"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"/>
</LinearLayout>
</HorizontalScrollView>
What Is Happening
This is an image of the correct scroll to the left. The edge of the scroll view starts on the right of the red bar. Notice the distance between the two.
This is an image of the incorrect scroll right. Compare the distances between the edges of the scroll view and where the scroll bar is stopping.
This is how I want it to look when I scroll at either end.
I have been playing with this for a while now and finally found the solution.
I was trying to add the left and right margins to the LinearLayout with the ID group_container. However for some reason the HorizontalScrollView was not respecting this and this is why I was seeing this issue.
Instead I added the left and right margins to the group_one and group_two LinearLayouts. Now the HorizontalScrollView respected these and it functions as I expected. Here is my modified code.
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="horizontal"
android:id="#+id/map_plugin_scroll_view"
android:background="#color/map_plugin_background">
<!-- Enclosing box to layout the two groups.-->
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginTop="8dp"
android:layout_marginBottom="8dp"
android:id="#+id/group_container">
<!-- These layouts contain the map plugins. -->
<LinearLayout
android:id="#+id/group_one"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"/>
<LinearLayout
android:id="#+id/group_two"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"/>
</LinearLayout>
</HorizontalScrollView>
set padding right to your scrollview like this :
android:paddingRight="20dp"
I'm having issues with a Fragment consisting of a ScrollView containing a LinearLayout. I'm trying to create an effect where the LinearLayout has a white background and looks like a piece of paper scrolling on a coloured background. The way that I'm trying to achieve this is by having the ScrollView occupy the full space of the fragment and then the LinearLayout inside has android:layout_margin="16dp" to create the space around the "paper".
This way, the scroll bar of the ScrollView appears in the coloured background area, the margin at the top scrolls away along with the content and the margin at the bottom only scrolls in when one reaches the end.
Unfortunately in this configuration the ScrollView won't scroll all the way to the end and in fact cuts off a very small amount of the text at the bottom. I suspect that the ScrollView isn't taking into account its child's margins in its vertical scrolling distance. To solve this I've wrapped the LinearLayout in a FrameLayout which solves the issue, but seems superfluous. Any pointers on how to eliminate this unneeded container would be appreciated.
Note: setting android:padding="16dp" on the ScrollView and scrapping the margins doesn't have the desired effect, as then the padding appears on all four edges continuously, regardless of scroll position.
<?xml version="1.0" encoding="utf-8"?>

<!-- This FrameLayout exists purely to force the outer ScrollView to respect

</LinearLayout>

I remember having trouble with the ScrollView somehow not making it to the end of it's contents when the content layout had a top margin. I solved the problem with a little hack, adding an empty view to the end of the LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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"
tools:context=".ArticleFragment" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp"
android:layout_margin="16dp" >
<TextView
android:id="#+id/article_title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textIsSelectable="true"
android:background="#color/page_background" />
<TextView
android:id="#+id/article_content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textIsSelectable="true"
android:background="#color/page_background" />
<!-- Add a little space to the end -->
<View
android:layout_width="fill_parent"
android:layout_height="30dp" />
</LinearLayout>
</ScrollView>
I used a similar empty view also in the beginning of the LinearLayout to avoid top/bottom margins completely.
EDIT: I just realised that you also wanted the end of the "paper" to show up when reaching the end of the view. In that case you might want to set the background color to the TextViews instead of the layout itself. Then make sure there's no margin between the title and the article (use padding as separation).
EDIT2: I should learn to check when the questions were asked... Well, maybe this still helps someone. :)
The question is old, but I've had issues with ScrollView being ill-behaved when wrapping FrameLayout. It also doesn't seem to consider the margins of contained layouts. You could replace the FrameLayout with another single-child LinearLayout, which should measure correctly. I would've removed the FrameLayout completely and simply added summed margin with padding on the inner layout:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="26dp"
android:background="#color/page_background" >
<!--...-->
I'd get rid of the FrameLayout and make the LinearLayout the child of the ScrollView with match_parent set as the layout height. If that still doesn't work, consider replacing the bottom margin with another arbitrary View with the desired height and background as the last item in the LinearLayout.
First off, this is not a duplicate question, to best of my ability I've tried all (there are many) similar questions. Solutions to such problems appear to be very subjective, specific to a given scenario.
My layout currently appears as follows. Black boxes are images (logo and body, respectively), colours represent each layout:
My XML:
<?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="#000"
android:padding="0px"
android:layout_margin="0px"
android:orientation="vertical">
<LinearLayout
android:layout_weight="16"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFF"
android:gravity="top|center"
android:orientation="horizontal">
<ImageView
android:id="#+id/logo"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/logo"
android:layout_gravity="top|center" />
</LinearLayout>
<LinearLayout
android:layout_weight="4"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#00F"
android:gravity="bottom|left"
android:orientation="vertical">
<ImageView
android:id="#+id/body"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/body"
android:layout_gravity="bottom|left" />
</LinearLayout>
</LinearLayout>
Here you can see I have a parent linear layout, split into two children linear layouts. This is because I need the images to be positioned differently within that part of the page.
In a nutshell, I need logo to be vertically aligned to the top, and body horizontally aligned to bottom-left.
Now, a few things that I've tried:
Using RelativeLayout rather than Linear
Switching gravity with layout_gravity for both LinearLayout and ImageView, along with combinations of excluding each
Fairly confident match_parent for width and height is what I want, but I have tried different combinations with wrap_content
What I've come to understand:
gravity:top requires the parent view use orientation:horizontal
gravity:left requires the parent view use orientation:vertical
gravity applies to the children of the view
linear_gravity applies how the child aligns with it's parent
Using the same value for gravity on the parent and linear_gravity on the child might have the same effect (when using one instead of the other)?
Hopefully this is enough information. I'm having a very difficult time wrapping my head around how these layouts work.
Thank you SO much for the help!
I think your problem is you are setting dimensions of the image views to match_parent. I would use a RelativeLayout as it seems to be the most efficient in your case (pseudo-XML-code):
RelativeLayout (width=match_parent, height=match_parent)
ImageView (width=wrap_content, height=wrap_content,
alignParentTop=true, centerHorizontal=true)
ImageView (width=wrap_content, height=wrap_content,
alignParentBottom=true, alignParentLeft=true)
You don't need any gravity setting here. You might want to play with the scaleType attribute depending on your image sizes.
