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 .

Android Fill the background color to entire height

Hi am trying to design a android app.
I have added a background color for my activity. my problem is the background color get filled the entire screen if there is content only. currently it looks like this.
Only half of the page is filled with background color.
can someone help me to fill the background with entire color.
Here is my xml code.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<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:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context="lk.agent.certislanka.certisagenttracking.ForgotPassword"
android:background="#ffd4d4d4">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="#string/forgot_password"
android:id="#+id/txt_v_forgot_password"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_marginTop="64dp" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
android:singleLine="true"
android:hint="Enter Email Address"
android:ems="10"
android:id="#+id/et_email"
android:layout_below="#+id/txt_v_forgot_password"
android:layout_alignParentStart="true"
android:layout_marginTop="33dp" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/Submit"
android:id="#+id/btn_reset_password"
android:background="#F89B22"
android:layout_below="#+id/et_email"
android:layout_alignParentEnd="true"
android:layout_marginTop="22dp" />
</RelativeLayout>
</ScrollView>

Set the ScrollView's fillViewport attribute to "true":
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">

Add this to your ScrollView
android:fillViewport="true"
Here problem is your layout doesn't have enough contents to fill the viewport. So only that much part of screen is having layout. So if you add android:fillViewport="true", then ScrollView will fill Viewport even when there is no enough content.
Your ScrollView, updated
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true" >
....
....
</ScrollView>

Give the background attribute (android:background="#ffd4d4d4") to the ScrollView

use the following code, fill the color in scrollview
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffd4d4d4">

Android: How to create a specific horizontal linear layout

I am making an app where there is a custom search bar. I want there to be a search part that is big, a spinner for region selection that is a small square, and a search button that is also a small square.
Here is what I am talking about.
The code I have right now is this:
<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:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".MainActivity">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<EditText
android:hint="#string/summoner_name"
android:layout_width="wrap_content"
android:layout_weight="75"
android:layout_height="wrap_content"
android:id="#+id/summoner_name"/>
<Spinner
android:layout_weight="1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/regions">
</Spinner>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:id="#+id/search_button"/>
</LinearLayout>
However, this makes the search half the screen, and the button for 2/5's the screen, and the spinner for a smaller ammount. Anyone know how to accomplish this?
Thanks :)

give weight 1 to EditText android:layout_weight="1" , and remove weight tags from other components.
Also you will require to set Spinners width statically, if above doesnt work because of Spinner's width part

like this?
<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:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="#dimen/activity_vertical_margin" tools:context=".MainActivity"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<EditText
android:layout_width="wrap_content"
android:layout_weight="75"
android:layout_height="wrap_content"
android:id="#+id/summoner_name"/>
<Spinner
android:layout_weight="1"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:id="#+id/regions"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:id="#+id/search_button"/>
</LinearLayout>
</LinearLayout>

Make scrollview in layout (crash)

I'm trying to make a screen scrollable with scroll view but my application keeps crashing.
What I've done is to replace RelativeLayout by ScrollView, but it doesn't work.
I need your help with this. Here is the code of the screen:
<RelativeLayout 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:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:paddingBottom="0dp"
android:background="#drawable/background01"
tools:context=".MainActivity"
android:id="#+id/relativeLayout">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/id"
android:background="#drawable/lightcontainer"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:weightSum="1"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:layout_marginBottom="16dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/mainTitle1"
android:id="#+id/textView"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp"
android:textSize="20sp"
android:textColor="#ffffff"
android:shadowColor="#000000"
android:shadowRadius="1.5"
android:shadowDx="2"
android:shadowDy="2"/>
</LinearLayout>

what you are trying to do is not an scrollable view it's just a relative layout. Try to put your code inside a ScrollView component, like this:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<!-- PUT YOUR CODE HERE -->
</ScrollView>
Make sure you close all tags correctly as well (your relative layout is not closed).
<RelativeLayout>
Content
</RelativeLayout> <-- This closing tag is always necessary

linear layouts not spacing correctly

Hey im having trouble with these linear layouts in android xml. initially i did them in a relative layout and it worked fine, but after some research i discovered that relative layouts inside of a scrollview doesnt work supposedly. so now after much tweaking my imageview shows up but has a huge margin above and below it and my textview doesnt even show up aside from being where its supposed to in the graphics editor but blank.
so whats wrong? should i even be using a linear layout?
this is roughly what its supposed to look like http://www.mediafire.com/view/?z945tz2vrb2x46t
and this is what it looks like after Abdul and Ralgha's help as well as setting the base linear layout's height to wrap content http://www.mediafire.com/view/?px17q2z3yyeo8az
Thanks

`![screwed up layout][1]

Don't worry about weight right now, leave it removed. In your TextView, change "android:src" to "android:text" (without the quotes naturally). If that alone doesn't solve it, remove the textSize line and see what happens. If that works, then you can start playing with sizes (and weights if needed).
Also, textSize should be given in sp rather than dp. sp is for text, dp is for everything else, though that's not what is causing your problem.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<TextView
android:id="#+id/today"
android:textSize="30sp"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="#string/today"

<ImageView

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/weeklylist_blocks"

</LinearLayout>

android:layout_weight="1"
might be the cause of your problems

Its works like charm, Use the following coding to achieve your thing:
<LinearLayout 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:gravity="center_vertical"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:fillViewport="true" >
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:orientation="vertical" >
<TextView
android:id="#+id/today"
android:src="#string/today"
android:textSize="30sp"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:text="#string/today"
/>
<ImageView
android:id="#+id/image1"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:contentDescription="#string/nissan"
android:src="#drawable/weeklylist_blocks" />
</LinearLayout>
</ScrollView>
</LinearLayout>
