I've got an activity, which is themed with Holo.Dialog (or plain old Dialog on older API levels), and contains a ScrollView as it's main layout, in case we encounter smaller screens that can't display all the content. My problem now is that the dialog is needing to scroll to see all the content, even when we have leftover vertical screen space, as seen below:
Here's the code for the ScrollView and it's one child, a LinearLayout:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical" >
What do I need to change to get this dialog to wrap more nicely? Thanks!
The solution that worked for me was to take the buttons out of the ScrollView and put them top level in a RelativeLayout. By putting the buttonbar first in the XML, aligned to parent bottom, and then setting the scrollView's layout_above to the buttonBar, I got the effect I was looking for

Background
I have a RelativeLayout inside a FrameLayout/RelativeLayout (doesn't matter to me), which should be at the bottom of the screen (like a toolbar), and should hold a few views in it.
Its height is set to "wrap_content" and so does its child-views.
The child-views of this layout are : A textView that is on the left, and a Horizontal LinearLayout on the right with a few buttons.
The problem
It seems that no matter what I do, the textview is causing the RelativeLayout to take the whole space, instead of just its children.
The code
Here's the minimal XML content that causes this problem. I've removed the extra stuff (LinearLayout and its children, and also some attributes that don't matter) since they don't cause this problem in case I remove the TextView:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF000000" >
<!-- Here I've put some views that don't have any relation with the views below, so it doesn't have anything with do with the problem -->
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#drawable/vertical_gradient_transparent_to_black" >
<!-- Here I've put a LinearLayout that doesn't cause the problem, so I've removed it for simplicity-->
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
</RelativeLayout>
I've tried many possible attributes, and also tried adding additional layouts to try to "fool" the RelativeLayout, but none of those have succeeded.
The question
Why does it occur?
A working solution would be to use a Horizontal LinearLayout (with a weight for the TextView ) instead RelativeLayout , but I still want to know why can't I use a RelativeLayout, and why it occurs. Also how to fix it while still using RelativeLayout.
From the RelativeLayout doc:
Class Overview
A Layout where the positions of the children can be described in relation to each other or to the parent.
Note that you cannot have a circular dependency between the size of the RelativeLayout and the position of its children. For example, you cannot have a RelativeLayout whose height is set to WRAP_CONTENT and a child set to ALIGN_PARENT_BOTTOM
Class documentation
Which is exactly your case. RelativeLayout can not do that.
I have encountered the same issue before, this might be caused by android:layout_alignParentBottom attribute.Maybe you can find another way to achieve your desired effect. See this for more information.
This is some kind of Strange issue. Maybe someone else has the explanation.
I found it working when i removed the line
android:layout_alignParentBottom="true"/>
and it also worked when i tried some like this
<TextView
android:layout_width="match_parent"
android:layout_alignParentTop="true"
android:layout_height="wrap_content"/>
Good day (or evening, or night)
I'm developing an app for android and I'm very curious about one thing. I have an activity, where user chats with another, like "im" chat. There are an EditText on the bottom and some kind of actionbar on the top. What I need is when user enters a message and the software keyboard is on screen, my activity should move up, but the actionbar should still be "glued" to the top of the screen, because it has some valuable controls on it.
Again, that's not an ActionBar, but just a 48dp height layout in a parent vertical linear layout. So I need to know is there an easy way to prevent it from moving to the top, when the layout moves off the screen.
I tried to put everything in a FrameLayout and put this bar on top of it, but on keyboard opens it goes off the screen too...
On you Activity at AndroidManifest you should put this: android:windowSoftInputMode="adjustResize"
Use something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.myapp.MyActionBar
android:layout_width="match_parent"
android:layout_height="48dp"/>
<LinearLayout
android:id="#+id/mylayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1dp"/>
<!-- Add your edittext and button -->
</LinearLayout>
This will make sure the actionbar and edittext + button are allways on screen, and the mylayout takes up the rest of the screen. When your keyboard is shown, the mylayout will shrink.
Try adding android:windowSoftInputMode="adjustResize" to your activity in the manifest. This tells Android to completely resize your layout when the keyboard comes up, rather than pan it. Note that if there isn't enough room for the entire layout this still won't work. But you ought to be able to make it work if your top level layout is a RelativeLayout, with the edit text set to align bottom, the top bar to align top, and the middle section to fill_parent and be above the edit text and below the bar.
use a RelativeLayout as your base Layout and add android:layout_alignParentTop="true" to your action bar to keep it up
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/action_bar_layout"
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_alignParentTop="true" >
</LinearLayout>
<TextView
android:id="#+id/text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
</RelativeLayout>
After much research on both SO and google, I haven't seen any one with exactly the same problem I am experiencing, so here it is:
I recently redid the entire UI on an android app. For the most part, I made only cosmetic changes to each of the screens. They appear in the UI editor of eclipse perfectly as expected. However, directly after doing this, two of the screens stopped being laid out correctly on both all tested devices and the emulator.
Now, the big problem one these two screens was that the root level LinearLayout didn't appear to be actually honoring the fill_parent for either layout_height or layout_width. it looks like it's being measured as if it were set to wrap_content instead. It only takes up about 70% of the screen - which is just enough to wrap the individual elements inside the root LinearLayout. I would post an image, but as a new user, I am not allowed to.
The layout isn't stretching to fill the screen. Here's the code for layout, except that there are a few more in the LinearLayouts containing a TextView and an EditText.
<?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:background="#FF000000"
android:orientation="vertical" >
<TextView
style="#style/sans.white.16.bold"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="4dp"
android:text="#string/edit_account" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<com.teamunify.ondeck.widget.TUTextView
style="#style/sans.white.14"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text="#string/first_name" />
<com.teamunify.ondeck.widget.TUEditText
android:id="#+id/acc_editor_first"
android:layout_width="fill_parent"
android:layout_height="40dp"
android:selectAllOnFocus="true"
android:singleLine="true" />
</LinearLayout>
I think the root LinearLayout should be filling both height and width. I've used this same layout many MANY times in our app without problems. (A quick count revealed that I used 76 LinearLayouts in our app, and all but two of them are working.)
At first, I suspected that perhaps our custom classes measure was wrecking things, so I changed the layout to use all plain EditTexts, but there was no change. I double checked the activity, but it isn't doing anything except to load this xml. So, in desperation, I redid the layout like so:
<?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:background="#FF000000"
android:orientation="vertical" >
<TextView
style="#style/sans.white.16.bold"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center|top"
android:paddingTop="4dp"
android:text="#string/edit_account" />
</LinearLayout>
After that, The words Edit Account appear with a black background mashed into the upper left corner. Clearly, the LinearLayout isn't filling the parent.
Long story short, I am asking how to fix this so that the LinearLayout fills the screen as expected.
I am at a complete loss as to why this is happening, and I am certainly hoping that someone on SO has an idea. This has got me pulling my hair out!
Try setting fixed width and height for the root layout.
Then only you will be able to debug who is driving length and width. It is very much possible that parent activity or background activity is setting dimensions. Once you identify the root cause you can go back to original settings.
As of now from your code snippet given here, nothing wrong here
If you use a custom activity as a container to other activities for some reason (In our case, we were recreating the look of our iOS app, and needed a custom menu to show up along the button side of the screen) the window manager seems to get a bit confused with what the actual height and width of the nested activities should be. A call to fillparent or matchparent ends up wrapping the content instead.
We ended up changing the behavior of several methods in our container activity class to make this work.
I have many activities with a scrollview inside a tablelayout. However, it is necessary a small design change, so I have to put a black transparent view over the whole screen from the top to the bottom. Is it possible to do it in the tablelayout or the scrollview?
RelativeLayout allows for easy overlapping of views. You'll have to adjust the existing views in your app because it doesn't do anything automatically.
EDIT:
A quick way to do this would be to take your existing view (the ScrollView) that is already organized and put it in a top-level RelativeLayout. Then, all you have to do is add new view inside the RelativeLayout with the width and height both set to MATCH_PARENT. The result should be the black transparent view will be visible over the ScrollView.
I normally use FrameLayout to achieve any kind of 'layering' of views.
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
//your existing layout
<View
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#33000000" />
</FrameLayout>
As DeeV said, you can probably use RelativeLayout in a similar way, but you might have to set additional attributes on its children to achieve this.
I am trying to make a selection ListActivity, similar to the one used to add shortcuts to the launcher screens. I have rolled my own header and footers, which I would like to be "sticky" at the top and bottom of the view when on screen. In order to do this, I am using a RelativeLayout with the header set to dock to top, footer set to dock to bottom, and the list set to go below the header and above the footer. In terms of the overall layout of the activity, this is rendering as I would expect. The header is sticky to the top, the footer is sticky to the bottom, and the list scrolls in between them.
One odd thing though happened when I switched to the RelativeLayout as my root. Please see the following screenshot:
I want my Activity's height to be wrap_content, so that the form is only as high as the content displayed in it, but once i switched to RelativeLayout, it seems to render the Activity effectively as fill_parent, taking up the whole screen, even though the content doesn't warrant it. Notice that there are not enough list items to fill the screen, which with the fill_parent style, is leaving a bunch of whitespace between the end of the list, and the footer. I was setting my height's via styles - which worked fine with LinearLayout, but seems to be ignored now. So I tried hard-coding the height directly on the RelativeLayout, but it still doesn't work and still renders as fill_parent.
Here is my layout code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="#style/GroupsList"
android:layout_height="wrap_content">
<FrameLayout android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:id="#+id/hdrGroups"
android:layout_alignParentTop="true">
<include layout="#layout/title"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</include>
</FrameLayout>
<FrameLayout style="#style/MyFooter"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_alignParentBottom="true"
android:id="#+id/ftrGroups">
<ImageView style="#style/CloseButton"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="#drawable/add"
android:id="#+id/imgGroupsAdd"
android:clickable="true">
</ImageView>
</FrameLayout>
<ListView android:divider="#9f9f9f"
android:id="#+id/android:list"
android:choiceMode="singleChoice"
android:dividerHeight="1dp"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_below="#id/hdrGroups"
android:layout_above="#id/ftrGroups">
</ListView>
<TextView android:text="#string/browser_no_groups"
style="#style/ListedItemB"
android:id="#+id/android:empty"
android:layout_height="wrap_content"
android:layout_above="#id/ftrGroups"
android:layout_below="#id/hdrGroups"
android:layout_width="fill_parent">
</TextView>
</RelativeLayout>
All layout is done via XML, ... I am not doing any layout in code.
How can I get the sticky header and footer while also having the activity as a whole behave in a wrap_content mode for its height? Is there some other way I should be going about this instead of a RelativeLayout?
According to the developer documentation your desired behaviour is not possible for Relative layout ;
"Note that you cannot have a circular dependency between the size of
the RelativeLayout and the position of its children. For example, you
cannot have a RelativeLayout whose height is set to WRAP_CONTENT and a
child set to ALIGN_PARENT_BOTTOM."
RelativeLayout
To solve your problem you could maybe try to use a linear layout, set to wrap_content and set max height via code to screen height.
You can get the screen height as described here : get screen height
I just change my RelativeLayout in FrameLayout and all starts to work
