set space between rows in listview Android

I have a listView with custom rows and I need to set a custom divider between each row.
This is the code of the listView:
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="#dimen/menu_padding"
android:background="#color/customBlue"
android:divider="#drawable/list_divider"
android:dividerHeight="2px" />
This is the code of the rows:
<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="50dp"
android:orientation="horizontal"
tools:ignore="contentDescription"
android:background="#color/strongBlue" >
<ImageView
android:id="#+id/row_icon"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="10dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/row_title"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:padding="10dp"
android:textColor="#color/white"
android:textAppearance="#android:style/TextAppearance.Medium" />
</LinearLayout>
And this is the code for the 2 pixel divider:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:bottom="1px">
<shape android:shape="line">
<stroke
android:color="#0C0832"
android:width="2dp"
/>
<size
android:height="1px"
/>
</shape>
</item>
<item android:top="1px">
<shape android:shape="line">
<stroke
android:color="#2D2E57"
android:width="2dp"
/>
<size
android:height="1px"
/>
</shape>
</item>
</layer-list>
The problem is that I have a random space between each row that has the same color as the listView backgroundColor and if I set the dividerHeight to 4px I can see my divider. How can I remove the space that gets created automatically and only have my custom divider?

Use the following code in rows in linear layout
android:layout_marginTop="15dp"

Instead of pixel you can provide dp in xml
android:dividerHeight="10dp"
android:divider="#ffffff"
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="schemas.android.com/apk/res/android">;
<gradient
android:type="radial"
android:startColor="#343030"
android:endColor="#151515"
android:gradientRadius="300"
android:angle="270"
android:centerY="0.3"/>
</shape>
Instead of making custom drawable for divider you can directly give color to divider.

adding shadow on the bottom of List item of Listview

I want to add shadow to bottom of my ListView item !!
I tried paddingEdageLenght but no change happened !
I added circular edges but i can't add the shadow below the item

android:fadingEdgeLength="5sp"
android:dividerHeight="10sp"

</RelativeLayout>
any help ?

In list_view_item, add a dummy View after your RelativeLayout and wrap them all at vertical LinearLayout like this:
<LinearLayout
android:orientation="vertical">
<RelativeLayout>
...
...
</RelativeLayout>
<View
android:id="#+id/shadow"
android:layout_width="fill_parent"
android:layout_height="3dp" <!--or your needed height value-->
android:background="#drawable/shadow_drawable">
</View>
</LinearLayout>
and at drawable folder add the new shadow_drawable.xml and put this at it
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android=”http://schemas.android.com/apk/res/android”>
<gradient
android:startColor="#color/#000000" <!--black-->
android:endColor="#color/#FFFFFF" <!--white-->
android:angle="90" <!-- angle of the gradient-->
>
</gradient>
</shape>

you have to add footerview in listview,
how to add footerview check bellow code,
private View footerView;
footerView = ((LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.listview_footer, null, false);
ListView.addFooterView(footerView);
so, what ever you can do, in footer view.

You can make 9-patch image for border with shadow effect.
Create a new drawable resource file named "border.xml" in "res/drawable" and write the following code-
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item >
<shape
android:shape="rectangle">
<gradient android:startColor="#ddd" android:endColor="#555" android:type="linear" />
<corners android:radius="0dp"/>
</shape>
</item>
<item android:right=".5dp" android:left=".5dp" android:bottom="2dp" android:top=".5dp">
<shape
android:shape="rectangle">
<solid android:color="#android:color/white"/>
<corners android:radius="0dp"/>
</shape>
</item>
</layer-list>
Just put android:background="#drawable/border" where you want to apply border.
You can change in android:right,android:left,android:top and android:bottom to give size to border. you can also make change in android:shape for more effect.
Hope its help for you !

android listview item's border

good day.
today i was encounted this next problem:
i have listview:
<ListView
tools:listitem="#layout/list_view_item"
android:listSelector="#android:color/transparent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:dividerHeight="0dp"
android:divider="#color/transparent"
android:cacheColorHint="#color/transparent"
android:id="#+id/items"/>
where list_view_item is:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/listview_item_background">
...
</LinearLayout>
and listview_item_background next:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle">
<solid android:color="#color/black" />
<padding
android:right="1dp"
android:top="1dp"
android:bottom="1dp"
android:left="1dp"/>
</shape>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#color/green"/>
</shape>
</item>
</layer-list>
now then i run my app i see next:
as you can see between adjacent items horizontal border are same with vertical border, but i was expected double-bordered
then i try to set listview divider to 1dp. as expected i have three-bordered result
then i test my background drawable not in listview, but simple three linearlayout. i have expected result with double-border...
<LinearLayout
android:orientation="vertical"
android:padding="10dp"
android:layout_width="100dp"
android:layout_height="100dp">
<View
android:layout_width="50dp"
android:layout_height="25dp"
android:background="#drawable/listview_item_background"/>
<View
android:layout_width="50dp"
android:layout_height="25dp"
android:background="#drawable/listview_item_background"/>
<View
android:layout_width="50dp"
android:layout_height="25dp"
android:background="#drawable/listview_item_background"/>
</LinearLayout>
but in listview i still have one border.
how i can create listview with horizontal double-border on adjacent item?

ok, i didn't fix it, but i find workaround (but in my opinion it is a cruch):
in my drawable i set bottom padding form 1dp to 2 dp

How to assign padding to Listview item divider line

How can i give padding to list item as i show in image.
I want to make the divider in the layout as shown in the image.
this is my list fragment code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp">
<ListView
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:id="#+id/listV_main"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"/>
This is my List section code
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="10dp"
android:paddingTop="10dp"
android:paddingRight="10dp"
android:paddingBottom="10dp">
<include
android:id="#+id/list_item_section_text"
layout="#android:layout/preference_category"
/>
This is my list item code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="?android:attr/listPreferredItemHeight"
android:adjustViewBounds="true"
android:paddingRight="?android:attr/scrollbarSize"
>
<ImageView
android:id="#+id/showlist_item_entry_drawable"
android:layout_width="82dp"
android:adjustViewBounds="true"
android:layout_height="68dp"
android:scaleType="fitXY"
android:paddingLeft="9dp"/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dip"
android:layout_marginRight="6dip"
android:layout_marginTop="6dip"
android:layout_marginBottom="6dip"
android:layout_weight="1"
>
<TextView android:id="#+id/list_item_entry_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceLarge"
android:ellipsize="marquee"
android:fadingEdge="horizontal" />
<TextView android:id="#+id/list_item_entry_summary"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/list_item_entry_title"
android:layout_alignLeft="#id/list_item_entry_title"
android:textAppearance="?android:attr/textAppearanceSmall"
android:singleLine="true"
android:textColor="?android:attr/textColorSecondary" />
</RelativeLayout>

Use 'inset'.....
(list_divider.xml)
<?xml version="1.0" encoding="UTF-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="50dp"
android:insetRight="50dp" >
<shape>
<solid android:color="#color/orange" />
<corners android:radius="2.0dip" />
</shape>
</inset>
and in your list view add like this...
<ListView
android:dividerHeight="2dp"
android:divider="#drawable/list_divider"
...
/>
you can set the inset value as desired...
UPDATE
As pointed out by #Giulio Piancastelli , If the background of list container is different from background of list item then you may use 'layer-list'...
(list_divider.xml)
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<solid android:color="#color/list_background" />
</shape>
</item>
<item
android:left="10dp"
android:right="10dp">
<shape android:shape="rectangle" >
<solid android:color="#color/divider_color"/>
</shape>
</item>
</layer-list>
and in your list view add like this...
<ListView
android:dividerHeight="2dp"
android:divider="#drawable/list_divider"
...
/>

You need padding for dividers? Create your custom drawable-shape as:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:left="10dp"
android:right="10dp">
<shape android:shape="rectangle" >
<solid android:color="#android:color/black" />
</shape>
</item>
</layer-list>
And set as divider for your ListView in xml:
<ListView
android:dividerHeight="2dp"
android:divider="#drawable/custom_divider"
...
/>
UPD
I just have ListView in xml:
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:dividerHeight="2dp"
android:divider="#drawable/line"
/>
Divider as line.xml in drawable:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:left="10dp"
android:right="10dp">
<shape android:shape="rectangle" >
<solid android:color="#android:color/black" />
</shape>
</item>
</layer-list>
Do not make any modifications on the ListView in code. You can try to use Clean if resources are wrong builded.

As #Giulio Piancastelli mentioned under #ASP answer, the <inset> fails when the background colour of the list container is not the same as the rows inside the list. One solution is to use <layer-list> like below:
//This item is to overlay the container colour with the row background colour
<item
android:left="0dp"
android:right="0dp">
<shape android:shape="rectangle" >
<solid android:color="#color/row_background" />
</shape>
</item>
//This item is the divider, put it at bottom so it will overlay the background colour
<item
android:left="92dp"
android:right="0dp">
<shape android:shape="rectangle" >
<solid android:color="#color/divider
</shape>
</item>
Then you can set it as divider as most answers suggest:
<ListView
android:dividerHeight="2dp"
android:divider="#drawable/layer_list"
...
/>

In your listitem give the paddingtop to the main layout as
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:padding="10dp"
....// Remaining fields
>
... //Remaining items
</LinearLayout>

this should be alternative solution for this question:
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_alignParentBottom="true"
android:background="color/secondary_text"
android:layout_marginTop="16dp" />

I don't know why people are adding shape to the layered-list but for me this works just fine.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="10dp" android:height="2dp" android:drawable="#android:color/holo_blue_dark"/>
<item android:height="22dp" android:drawable="#android:color/transparent"/>
</layer-list>
1st item will be 10dp from the top and with a height of 2dp and a color of holo_blue_dark. (This will be the divider)
Now to give 10dp margin to bottom we need to create another transparent item with a height of 22dp (10dp (top margin) + 2dp (height of divider) + 10dp(bottom margin from divider)).
This is working fine for me. I hope this will work for you too.

set your list item divider height and color:
<ListView
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:id="#+id/listV_main"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"
android:divider="#android:color/darker_gray"
android:dividerHeight="1dp"/>

Adding rounded corners to a mapview

I'm trying to code a simple MapActivity which uses the following layout (only contains the mapview for the moment, as I plan to add share the screen with a ListView in the future) :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.google.android.maps.MapView
android:id="#+id/mapview"
android:layout_width="fill_parent"
android:layout_height="200dip"
android:enabled="true"
android:clickable="true"
android:apiKey="mykey"
android:layout_alignParentBottom="true" />
</RelativeLayout>
I have applied a simple shape to the mapview in order to have round corners and a stroke :
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:bottomRightRadius="10dp"
android:bottomLeftRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>
<stroke android:width="3dp"
android:color="#color/bordure_tables" />
</shape>
I use the following to apply the shape :
mapView.setBackgroundResource(R.layout.map);
Problem is that it does not have any effect and I can't see my rounded corners, nor the stroke.

Just wrote a tutorial to have rounded corners on a MapView it's done programmatically so should scale well to all devices:
http://www.anddev.org/novice-tutorials-f8/rounded-corners-map-view-t56908.html
Once you have added the custom view class you can just instantiate a rounded mapview like so:
<com.blundell.tut.ui.widget.RoundedMapView
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>

Have you tried assigning it a padding?
<padding
android:left="2dp"
android:top="2dp"
android:right="2dp"
android:bottom="2dp" />
So your strokes and radius should be visible.

So I've achieved this affect by doing following: I've created a 9-patch drawable called round_corners and placed it in my drawable folder, then I use following xml to plot the map:
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">/
<com.google.android.maps.MapView
android:id="#+id/center_map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="your_key"
/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#drawable/round_corners"
></LinearLayout>
</FrameLayout>

I was able to achieve this creating a rounded drawable like this:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#android:color/transparent" />
<stroke android:width="10dp" android:color="#color/color_gray5_eeeeee" />
<corners android:radius="10px" />
</shape>
then using a linear layout and a margin of the same size of the drawable stroke width, like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/background_gray_rectangle_rounded_corners"
android:orientation="vertical">
<com.google.android.gms.maps.MapView
android:id="#+id/map_details_map_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:clickable="true"
android:enabled="true" />
</LinearLayout>

Just put the Mapview into a CardView
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="100dp"
android:elevation="0dp"
app:cardCornerRadius="5dp">
<com.google.android.gms.maps.MapView
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.support.v7.widget.CardView>
