Image does not touch the edges, Android [duplicate]

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 .

framelayout edittext not expanding as expected

I have a problem in edit text its not getting expanded as I type.
I wanted it to show a maximum of 4 lines but when I click the exittext to type something, its shrinking, not even completely showing a single line.
the code used is.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

screen shot of whats happening..
thank you..

You have two framelayouts nested in a linearlayout and they are weighted. The first nested framelayout has a weight of 11
compared to 1. So the edittext will not be able to expand beyond it's the weighted width for the framelayout.
<LinearLayout
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="0dp"
android:layout_weight="10">
The nested frames.
<FrameLayout
android:layout_height="0dp"
android:layout_width="match_parent"
android:layout_weight="11">
<FrameLayout
android:layout_height="0dp"
android:layout_width="match_parent"
android:layout_weight="1">
The total parent layout has been broken in 12 parts. The top frame has 11, the bottom 1. 1 is not much. There is not enough room to display all the text, plus you have a vertical scrollbar. The text will be added and be scrolling as you type. It would be impossible to read as it scrolls in such a short space.
I would even suggest not setting the weight for the bottom frame (it defaults to 0) and then try setting the top one to say 3? and increase it to see what works for you. Please try this, before commenting again.

Show 3 scrollable ListViews of equal height in Android Layout

I am trying to show three different vertical sections in my Android layout on one screen, each taking up one third of the screen, one on the top, one in the middle, and one on the bottom. Each section has a TextView and a ListView, and the ListViews can scroll so that you can see all items, but the overall page does not move. I have tried putting each TextView and ListView in a LinearLayout and setting the height of each LinearLayout to one third the total height of the screen, but the first ListView just shows all the items in it, taking up most of the screen, and the other sections are pushed down. I also tried using layout_weights, but for some reason it did not work. (EDIT: Setting layout_weight="1" ended up working, I'm not sure what I did wrong the first time) How can I make this work, or is there a better way to go about this?

<LinearLayout
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="horizontal" >
<ListView android:layout_width="0dp" android:layout_weight="1"
android:layout_height="match_parent" android:background="#FF0000"/>
<ListView android:layout_width="0dp" android:layout_weight="1"
android:layout_height="match_parent" android:background="#00FF00">
<ListView android:layout_width="0dp" android:layout_weight="1"
android:layout_height="match_parent" android:background="#0000FF">
</LinearLayout>
This will give you three equally wide columns: to make it rows, change the orientation to vertical and swap the values of layout_height and layout_width for each listview. If you need to add the TextViews, you'll have to make each listview in this code either a RelativeLayout LinearLayout or FrameLayout, using same width/height/weight and arranging the ListView and TextView inside to taste. To do this most efficiently, use a Framelayout and use a margin on the listview to offset it from the TextView. You can place the TextView relative to the ListView inside the FrameLayout by using the layout_gravity in the TextView.
Ie (swapping the first "column"):
<FrameLayout android:orientation="vertical" android:layout_width="0dp"
android:layout_weight="1" android:layout_height="match_parent"
android:background="#FF0000">
<TextView android:text="Column!" android:background="#3Eff0000"
android:layout_height="40dp" android:layout_width="match_parent">
<ListView android:layout_marginTop="48dp" android:layout_height="match_parent"
android:layout_width="match_parent" android:background="#8Aff0000"/>
</FrameLayout>

Use this:
<?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:layout_height="fill_parent"
android:layout_weight="1"
android:background="#ff89ff91">

ExpandableListview is not showing fully

The bottom part of the screen does not display rows even though they are loaded. When scrolled up, the rows move to the top and when invalidated the adapter, the application works fine by displaying the full screen.
Here is the layout am using.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/homescreenview"
android:orientation="vertical"
>
<LinearLayout
android:id="#+id/homescreenmainlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/internetstatus"
android:layout_width="match_parent"
android:layout_height="30dp"
android:gravity="center"
android:background="#912E3D">
<ImageView
android:id="#+id/interneticon"
android:layout_width="18dp"
android:layout_height="18dp"
android:src="#drawable/nonetwork"
/>
<TextView
android:id="#+id/internetstatustext"
android:layout_toRightOf="#+id/interneticon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:paddingLeft="5dp"
android:gravity="center_vertical"
android:text="#string/nonetconnection"
android:textColor="#color/white"
android:textSize="18sp"
android:textStyle="italic"
/>
</LinearLayout>
<ExpandableListView
android:id="#+id/expandableListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</ExpandableListView>
</LinearLayout>
Please find attached screenshot.

there is a trick to fill all the space in the screen, try this and let me know, you should set the height of your listview to 0dp and weigth to 1... Android will calculate height automatically for you.
<ExpandableListView
android:id="#+id/expandableListView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />

android element below list is gone when the list fills the screen

I have a LinearLayhout that contains a listView and below it an ImageButton.
When I add items to the list, the imageButton is moving lower and lower, which is what I want but when there are many elements in the list so that is the list is big enough to fill the screen, I can scroll down to the bottom of the list, but no further, meaning I can't see the imageButton anymore.
Code:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/add_interest_layout_root"
android:orientation="vertical"
android:layout_width="match_parent"
android:background="#color/back"
android:layout_height="match_parent">
<ListView android:id="#android:id/list"
android:layout_width="match_parent"
android:divider="#drawable/downa"
android:footerDividersEnabled="false"
android:cacheColorHint="#android:color/transparent"
android:layout_gravity="center"
android:layout_marginTop="6dp"
android:layout_height="wrap_content">
</ListView>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:id="#+id/linearLayout2"
android:gravity="center">
<LinearLayout
android:orientation="vertical"
android:gravity="center_horizontal"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/LinearLayout16">
<ImageButton
android:src="#drawable/add"
android:id="#+id/btn_interest_more"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center_horizontal"
android:background="#android:color/transparent"></ImageButton>
<TextView
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_width="wrap_content"
android:id="#+id/TextView08"
android:text="be more\nspecific"
android:gravity="center"></TextView>
</LinearLayout>
</LinearLayout>
What am I doing wrong? I want to be able to see the ImageButton even when I scroll down.

You should do something like this. Mind you this is a pseudo code so you better fill the correct attributes.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/add_interest_layout_root"
android:layout_width="match_parent"
android:background="#color/back" android:layout_height="match_parent">
<LinearLayout android:layout_height="wrap_content"
android:layout_width="match_parent" android:id="#+id/linearLayout2"
android:gravity="center" android:layout_alignParentBottom="true">
<!-- LinearLayout elements same as above -->
</LinearLayout>
<ListView android:id="#android:id/list"
android:layout_above="#+id/linearLayout2"
android:layout_width="match_parent"
android:divider="#drawable/downa"
android:footerDividersEnabled="false"
android:cacheColorHint="#android:color/transparent"
android:layout_gravity="center"
android:layout_marginTop="6dp" android:layout_height="match_parent">
</ListView>
</RelativeLayout>

Here is exactly the solution to your problem: http://www.curious-creature.org/2010/08/15/scrollviews-handy-trick/ which is solved by setting fillviewport on your listview.

Add this to your LinearLayout that holds the ImageButton
android:layout_alignParentBottom="true"
UPDATE:
Forget the above code. I misunderstand you. Sorry.
Do this instead: Add this layout as your root layout
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/scroll"
android:scrollbars="none"
android:layout_weight="1">
<!-- Your code -->
</ScrollView>
