I have the following code:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:src="#drawable/ducks_r2_c1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ImageView android:src="#drawable/ducks_r3_c1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:clickable="true"/>
<ImageView android:src="#drawable/ducks_r4_c1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:clickable="true"/>
<ImageView android:src="#drawable/ducks_r5_c1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:clickable="true"/>
<ImageView android:src="#drawable/ducks_r6_c1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:clickable="true"/>
</LinearLayout>
</ScrollView>
I have used layout_width="fill_parent" everywhere. But this is the screenshot of how it shows up on the emulator.
I dont want the space on either side of the images.
Why is it showing up like this? How can I rectify it?Thank you
I guess this is happening because the image is not streching.
You may try to ask the image to strech itself:
android:scaleType="fitXY"
or use it as background.
please check this thread:
android: stretch image in imageview to fit screen
A ScrollView will only inflate to as many items are in it.
You should be able to solve this by using a LinearLayout (or another more predictable layout) as the parent for your ScrollView with android:layout_height="match_parent" and setting the ScrollView to android:layout_height="wrap_content" and the same for layout_width on both.

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_height="wrap_content"

<ImageView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="img1"/>
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"

<ImageView

android:layout_width="wrap_content"
android:layout_height="wrap_content"

<ImageView

android:layout_width="wrap_content"
android:layout_height="wrap_content"

<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 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:orientation="vertical">

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:layout_height="wrap_content">

android:layout_width="match_parent" android:layout_height="wrap_content"
android:orientation="vertical">
<TextView android:id="#+id/tvDesc" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_margin="10dp"
android:gravity="center" android:paddingTop="40dp" android:text="#string/welcom"
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.
I have the following layout for a custom title bar. However, the problem is this: both the imageview and the imagebutton are coming at the centre. I was expecting the imagebutton to be at the extreme right. Can anyone kindly let me know what I did wrong here ? Thanks.

android:layout_width="fill_parent"

Your layout is only 35dip tall, so pressumibly if you show your ImageView the ImageButton gets positioned outside the screen. Consider changing your layout_height to wrap_content, if appropiate.
You're using a vertically oriented LinearLayout, all View will be presented in a vertical fashion. Use a RelativeLayout so that you'll have more control over where Views are positioned. If you'd still like to use a LinearLayout, you'll have to use horizontal orientation so that the Views can be on the same "line".
Use layout_gravity to layout the item to the right, just gravity is used by the contents of the view.
At first if width is set to fill parent it really fills parent so it use all the width.
Second: why not RelativeLayout? It provides more options and control.
Maybe this is what you looking for:

I've searched for an answer for this all over but the solutions offered did not solve my problem.
I have a layout where I display some views (a few buttons and a background). To this i've added a custom control i've made extending linear layout. This control is displayed above the layout quite nicely.
What I wish to do is add an additional ImageView which is larger than this control but it will be in front of it.
edited: Sorry, I hope this will clear things up.
I have one large layout (Relative) for my activity, I would like to stack on this layout two additional views\layout so the final version will be the picture attached:
This is my layout - which stacks the imageview right on the menubar, and not over the others. Trying to put the FrameLayout elsewhere still didn't give me the wanted result.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background">
<RelativeLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="450dip">
<com.myproject.controls.SearchControl
android:id="#+id/scSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<ExpandableListView android:id="#+id/lstItems"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/scSearch"
android:layout_marginLeft="26dip"
/>
</RelativeLayout>
<FrameLayout android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.myproject.controls.MenubarMain
android:id="#+id/mbMenuBarMain"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

<ImageView android:src="#drawable/myicon"

Not sure it this will work or not cause I'm typing this up at work. But moral of the story here is get used to using RelativeLayout. You have much more control over your layout.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background">
<com.myproject.controls.MenubarMain
android:id="#+id/mbMenuBarMain"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
</com.myproject.controls.MenubarMain>
<com.myproject.controls.SearchControl
android:id="#+id/scSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
</com.myproject.controls.SearchControl>
<ExpandableListView android:id="#+id/lstItems"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/scSearch"
android:layout_above="#id/mbMenuBarMain"
android:layout_paddingLeft="26dp"/>
<ImageView android:src="#drawable/myicon"
android:layout_width="200dp"
android:layout_height="200dp"
android:layout_alignBottom="#id/mbMenuBarMain"
android:layout_alignRight="#id/mbMenuBarMain"/>
</RelativeLayout>
I would like to make the following layout, see picture below, where the place of the EditText views stay correct positioned w.r.t. the arrows.
The layout below I've made with a RelativeLayout making use of margins, but this doesn't work when someone installs this app on a 540x960 resolution phone like the HTC sensations.
Thanks in advance for your help!

Use a combination of LinearLayout and RelativeLayout. With LinearLayout you can create spaces on the screen that will be exactly alike on all devices. Let your top level container be a LinearLayout. For instance, to create the second row in the image you reffered to, do something like this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1">
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true">
</TextView>
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1">
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true">
</TextView>
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1">
</RelativeLayout>
</LinearLayout>
