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 design : a scrollview 3 button below

I'm trying to create a design (and i'm pretty bad at this -__- ) where I will have a scrollview and a set of 3 buttons, horizontally aligned ALWAYS at the bottom of the screen (I mean the scrollview should be ABOVE my layout with my button and may scroll, but the button have to ALWAYS be displayed/visible)
I have already tried several solution, the last one I used is this , but it doesn't succeeded :(

NB : I have no need of the "header" part ... but the last code I found have it and it seems to be exactly I need.... seemed only -__- :(
And I have 2 questions on this design (while i'm asking, I ask everything :p )
1/ How may I force the size of the Image I will be downloading into ImageView1 to a "maximum" height (I mean my picture will be portrait OR landscape... let say 10*15 and 15*10 ... how may i forced them to be 10*6.666 instead of 15*10 <= It's an example... I don't know the image size I will have, but I know I want them at the same height every time, width may change according to the ratio)
2/why Lint is writing this part in red....
android:textAppearance="?android:attr/textAppearanceLarge"
Thx in advance to everyone who stops here and give me hints :)
(and sorry for my english)
EDIT : I have found some answer !! I used RELATIVELayout instead of LINEARLayout, which is recommended to do what I wanted ...
Si here is the "new" template (for reference if anyone is interested), where I still have problem
<?xml version="1.0" encoding="utf-8"?>

<Button

android:layout_height="wrap_content"
android:text="="

android:id="#+id/Bmoins"
android:onClick="onClickSuivant"
android:layout_toRightOf="#+id/Begale"
android:layout_toEndOf="#+id/Begale" />
</LinearLayout>
With the previous design, button were well aligned and take all the screen (match_parent) ... with this one, they are located at the bottom left ... As android:layout_centerHorizontal="true" is made for RelativeLayout, problem come from this... how may i change it ?

Try using android:gravity="center" in your LinearLayout (which encapsulates the buttons) or android:layout_gravity="center" in Button elements. I believe the first option will be enough.
EDIT: regarding Lint warning message, I believe it's related to this line:
android:text="Chargement en cours"
It's discouraged to use hard-coded strings. Try replacing it by android:text="#string/my_string_id" and define such string in your strings.xml file.

Android layout objects placement

I have this simple activity in my android app but I don't know how to place my button so it appears at the same position on various screen sizes.
I want the button to always be placed at the bottom of the screen. The screenshot shown is from a phone screen. When displayed on a larger screen the button is higher up.
How can I fix this?
Thanks
See this screenshot

You can use RelativeLayout with this parameter (android:layout_alignParentBottom="true")
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Click Me!"/>
</RelativeLayout>

You should use a RelativeLayout
If you have a RelativeLayout that fills the whole screen you should be able to use android:layout_alignParentBottom to move the button to the bottom of the screen.
If your button at the bottom doesn't show then probably the layout above it takes all the space. In this case you can put the button first in your layout file and position the rest of the layout above the views with android:layout_above.

Have a look a RelativeLayout. Use this ViewGroup and add a Button inside it with alignParentBottom
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
<Button
android:id="#+id/button_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:alignParentBottom="true"
android:text="HORAIRE"
android:layout_margins="<your_margin_in_dp>" />
</RelativeLayout>

Make footerButton.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:text="HORAIRE"
android:textColor="#ffffff"
android:textSize="20sp" />
</RelativeLayout>
And add it in all your layout file like below line:
Android Activity_Layout
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Footer aligned to bottom -->
<include layout="#layout/footer" />
<!-- Content above footer -->
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/footer"
android:layout_below="#id/header"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Content goes here"
android:textColor="#FFFFFF"
android:textSize="20sp" />
</RelativeLayout>
</RelativeLayout>
Hope it will solve your problem

This is what I ended up doing. Thanks to everyone who posted, it helped me get in the right direction!
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

tools:context="xxxx.MainActivity"
android:orientation="vertical"
android:weightSum="1">
<TextView
android:layout_width="wrap_content"

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

How to not overlapping with RelativeLayout

I'm trying to get a layout like this:
OK, I want the scroll to begin at the end of the first imageview and I want the scroll to finish at he start of the second imageview. I mean, I don't want imageviews to overlap the scroll. I don't know if I've explained well.
First I tried with LinearLayout but I can't align at the bottom the second ImageView. With RelativeLayout, ImageViews overlap the scroll, I can set margin-top to the scroll to solve the problem with the first ImageView, but I don't know how to solve the problem wit the second ImageView.
I also tried to use a RelativeLayout inside the LinearLayout like this:
<LinearLayout ....>
<ImageView ...></ImageView>
<ScrollView...></ScrollView>
<RelativeLayout...>
<ImageView....></ImageView>
</RelativeLayout>
</LinearLayout>
The second ImageView doesn't appear. I guess scroll is overlapping it.
I Would appreciate any help. Thanx you.

Use
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="#+id/imageViewTop"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageViewBottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:src="#drawable/ic_launcher" />
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/imageViewBottom"
android:layout_below="#+id/imageViewTop"
android:background="#006600" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</RelativeLayout>

In your xml, put your ListView below imageview1 and above imageView2.
Make sure to use a relativelayout as a parent.

you can do like this
<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:background="#android:color/black"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TextView
android:id="#+id/topView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white"
android:text="top view" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottomView"
android:layout_below="#+id/topView"
android:background="#android:color/holo_red_dark" />
<TextView
android:id="#+id/bottomView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#android:color/white"
android:text="bottom view" />
</RelativeLayout>
