I tried to use marginBottom on the listView to make space between listView Item, but still the items are attached together.
Is it even possible? If yes, is there a specific way to do it?
My code is below
<LinearLayout
android:id="#+id/alarm_occurences"
android:layout_width="fill_parent"
android:orientation="vertical"
android:layout_height="fill_parent"
android:background="#EEEEFF"
xmlns:android="http://schemas.android.com/apk/res/android">
<ListView
android:id="#+id/occurences"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
My custom List item:
<com.android.alarm.listItems.AlarmListItem
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/alarm_item_background"
android:layout_marginBottom="10dp"
>
<CheckedTextView
android:id="#android:id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:textSize="20sp"
android:textStyle="bold"
android:typeface="serif"
android:padding="10dp"
/>
</com.android.alarm.listItems.AlarmListItem>
How can I make spacing between list items in this case?
#Asahi pretty much hit the nail on the head, but I just wanted to add a bit of XML for anyone maybe floating in here later via google:
<ListView android:id="#+id/MyListView"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:divider="#android:color/transparent"
android:dividerHeight="10.0sp"/>
For some reason, values such as "10", "10.0", and "10sp" all are rejected by Android for the dividerHeight value. It wants a floating point number and a unit, such as "10.0sp". As #Goofyahead notes, you can also use display-independent pixels for this value (ie, "10dp").
Perhaps divider or dividerHeight property of the ListView can solve your problem.
Although the solution by Nik Reiman DOES work, I found it not to be an optimal solution for what I wanted to do. Using the divider to set the margins had the problem that the divider will no longer be visible so you can not use it to show a clear boundary between your items. Also, it does not add more "clickable area" to each item thus if you want to make your items clickable and your items are thin, it will be very hard for anyone to click on an item as the height added by the divider is not part of an item.
Fortunately I found a better solution that allows you to both show dividers and allows you to adjust the height of each item using not margins but padding. Here is an example:
ListView
<ListView
android:id="#+id/listView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
ListItem
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="10dp"
android:paddingTop="10dp" >
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Item"
android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>
You should wrap your ListView item (say your_listview_item) in some other layout e.g LinearLayout and add margin to your_listview_item:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<your_listview_item
android:id="#+id/list_item"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
...
...
/>
</LinearLayout>
This way you can also add space, if needed, on the right and left of the ListView item.
My solution to add more space but keep the horizontal line was to add divider.xml in the res/drawable folder and define line shape inside:
divider.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line" >
<stroke
android:width="1px"
android:color="#color/nice_blue" />
</shape>
then in my list I reference my divider as follows:
<ListView
android:id="#+id/listViewScheduledReminders"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_marginBottom="#dimen/mediumMargin"
android:layout_weight="1"
android:divider="#drawable/divider"
android:dividerHeight="16.0dp"
android:padding="#dimen/smallMargin" >
</ListView>
notice the android:dividerHeight="16.0dp" by increasing and decreasing this height I am basically adding more padding on top and bottom of the divider line.
I used this page for reference: http://developer.android.com/guide/topics/resources/drawable-resource.html#stroke-element
For my application, i have done this way
<ListView
android:id="#+id/staff_jobassigned_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#null"
android:dividerHeight="10dp">
</ListView>
just set the divider to null and providing height to the divider did for me.
Example :
android:divider="#null"
or
android:divider="#android:color/transparent"
and this is result
If you want to show a divider with margins and without stretching it - use InsetDrawable (size must be in a format, about which said #Nik Reiman):
ListView:
<ListView
android:id="#+id/listView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
android:divider="#drawable/separator_line"
android:dividerHeight="10.0px"/>
#drawable/separator_line:
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="5.0px"
android:insetRight="5.0px"
android:insetTop="8.0px"
android:insetBottom="8.0px">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#color/colorStart"
android:centerColor="#color/colorCenter"
android:endColor="#color/colorEnd"
android:type="linear"
android:angle="0">
</gradient>
</shape>
</inset>
You can use:
android:divider="#null"
android:dividerHeight="3dp"
example:
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/listView" android:layout_gravity="center_horizontal"
android:dividerHeight="3dp"
android:divider="#null" android:clickable="false"/>
I realize that an answer was already been selected, but I just wanted to share what ended up working for me when I ran into this issue.
I had a listView where each entry in the listView was defined by its own layout, similar to what Sammy posted in his question. I tried the suggested approach of changing the divider height, but that did not end up looking all too pretty, even with an invisible divider. After some experimentation, I simply added an android:paddingBottom="5dip" to the last TextView layout element in the XML file that defines individual listView entries.
This ended up giving me exactly what I was trying to achieve via the use of android:layout_marginBottom. I found this solution to produce a more aesthetically pleasing result than trying to increase the divider height.
Instead of giving margin, you should give padding:
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:divider="#android:color/green"
android:dividerHeight="4dp"
android:layout_alignParentTop="true"
android:padding="5dp" >
</ListView>
OR
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:paddingTop="2dp"
android:divider="#android:color/green"
android:dividerHeight="4dp"
android:paddingLeft="1dp"
android:paddingRight="1dp"
android:paddingBottom="2dp"
android:paddingStart="0dp"
android:paddingEnd="0dp" >
</ListView>
Simplest solution with OP's existing code (list items already have got padding) is to add following code:
listView.setDivider(new ColorDrawable(Color.TRANSPARENT)); //hide the divider
listView.setClipToPadding(false); // list items won't clip, so padding stays
This SO answer helped me.
Note: You may face a bug of the list item recycling too soon on older platforms, as has been asked here.
you just need to make background transparent of list divider and make height according to your needed gap.
<ListView
android:id="#+id/custom_list"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:divider="#00ffffff"
android:dividerHeight="20dp"/>
<ListView
android:clipToPadding="false"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:dividerHeight="10dp"
android:divider="#null"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
and set paddingTop, paddingBottom and dividerHeight to the same value to get equal spacing between all elements and space at the top and bottom of the list.
I set clipToPadding to false to let the views be drawn in this padded area.
I set divider to #null to remove the lines between list elements.
Also one more way to increase the spacing between the list items is that you add an empty view to your adapter code by providing the layout_height attribute with the spacing you require. For e.g. in order to increase the bottom spacing between your list items add this dummy view(empty view) to the end of your list items.
<View
android:layout_width="match_parent"
android:layout_height="15dp"/>
So this will provide a bottom spacing of 15 dp between list view items. You can directly add this if the parent layout is LinearLayout and orientation is vertical or take appropriate steps for other layout. Hope this helps :-)
This will help you add the divider height.
getListView().setDividerHeight(10)
If you want to add a custom view, you can add a small view in the listView item layout itself.
I found a not-so-good solution for this in case you are using a HorizontalListView, since dividers don't seem to work with it, but I think it'll work either way for the more common ListView.
Just adding:
<View
android:layout_marginBottom="xx dp/sp"/>
in the bottomest View of the Layout you inflate in the adapter class will create spacing between items
In order to give spacing between views inside a listView please use padding on your inflate views.
You can use android:paddingBottom="(number)dp" && android:paddingTop="(number)dp" on your view or views you're inflate inside your listview.
The divider solution is just a fix, because some day, when you'll want to use a divider color (right now it's transparent) you will see that the divider line is been stretched.
A lot of these solutions work. However, if all you want is to be able to set the margin between items the simplest method I have come up with is to wrap your item - in your case the CheckedTextView - in a LinearLayout and put your margin formatting for the item in that, not the root-layout. Be sure to give this wrapping layout an id and create it along with your CheckedTextView in your adapter.
That's it. In effect, you are instantiating the margin at the item level for the ListView. Because the ListView does not know about any item layout - only your adapter does. This basically inflates the part of the item layout that was being ignored before.
Maybe you can try to add android:layout_marginTop = "15dp" and android:layout_marginBottom = "15dp" in the outermost Layout

Can somebody tell me how can I remove the space between the listview border and the items inside the listview?
Remove margins from your xml listview layout.
If I understand your question properly, you are not looking for removing space between listview border and items (The red sign on your image says that! you want to remove space between two elements inside 1 item). If that is true, then you have to go to the custom layout file you created to set as a row for the listview. It looks like you have 2 TextViews there ("Go" and "Bro1, Bro2......"). There you have to play with the Margin-Up and Margin-Bottom of these 2 textviews.
android:layout_marginBottom="1dp"
android:layout_marginUp="1dp"
If you mean the space around the listview then either check the margins of the listview or paddings of the parent layout of the listview.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="0dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="0dp">
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0dp" />
</LinearLayout>
</RelativeLayout>
I would like to add padding to the top and bottom of a listview divider.
I have tried inserting android:dividerPadding="10dp"
property into my xml layout file.
But nothing happens. What do I need to change? Thank you all for your help.
<ImageView
android:id="#+id/background"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="backgroundDescription"
android:scaleType="centerCrop"
android:src="#drawable/photo_01" >
</ImageView>
<com.hb.views.PinnedSectionListView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/android:list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="#android:color/darker_gray"
android:dividerHeight="1dp"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false" />
</FrameLayout>
Would increasing the dividerHeight give you the effect you are looking for? Or try adding the padding to the divider drawable that will be the items in the list.
I follow a different approach to this, since drawablePadding doesn't give directions as Top, bottom etc.
What I do is add android:layout_marginTop to the first item in the List and android:layout_marginBottom to the last.
This automatically makes some space around the divider from top and bottom. (Not the conventional way, but works) :)
I need to create an application with a list-view activity, but the elements in the list should be separated one from another and have more then one click option:
Here is the image:
so i can click on the on the task to see the task details and i can click on the left side of the task (the colored part) to change it's color, and this way to change it's priority
i would really appreciate if some one could provide me with a tutorial or additional reading information to creating such custom lists.
divider and dividerHeight property of the ListView can make space between your listview items:
<ListView android:id="#+id/list_view"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:divider="#android:color/transparent"
android:dividerHeight="10.0sp"/>
You can find some tutorial on how to build an Android Listview with Multiple Clickable Zones
You need to create a custom xml layout for list item. and in a listview give devider heght..
like i did here.
<ListView
android:id="#+id/lstContact"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/lay"
android:divider="#0000"
android:dividerHeight="6dp"
android:layout_marginTop="3dp"
android:padding="5dp"
android:background="#0000"
android:cacheColorHint="#0000"
android:scrollbars="none" />
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp" >
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Label" />
</LinearLayout>
You can use this as the layout for your list row in your list adapter.
And you can acheive the spacing by increasing and decreasing the margin for the parent layout.
Hope it will help you
I think you need to mention a shape.xml for each styling your row. And then in your row layout use an RelativeLayout for arranging the items. And make sure that you make the android:background="#android:color/transparent" for each button you create there. First one will be an ImageButton.
This is what you can achieve. Let me know if this helps you.
I want to have a divider at the top of a ListView (which is placed in RelativeLayout), but when I try to use this, I get only the bottom divider:
<ListView
android:id="#+id/last_contacts_picked_list"
android:headerDividersEnabled="true"
android:footerDividersEnabled="true"
android:paddingTop="50dp"
android:dividerHeight="5dp"
android:layout_marginTop="50dp"
android:divider="#android:drawable/divider_horizontal_textfield"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="..."
android:layout_alignLeft="..."
android:layout_alignRight="..."
android:layout_below="..."
/>
I've got something like this:
http://i051.radikal.ru/1211/4f/a408db5e717f.png
Why doesn't it have the header divider too?
That is not what android:headerDividersEnabled is supposed to do. It means that if you are adding a list header whether that header needs to be separated by a divider or not.
For your problem simply use a linearlayout with ImageView having the divider as source followed by ListView. Hope this helps.
In my application, I am using fragments. The problem is I am not able to set margin for each item in the list inside TitlesFragment extends ListFragment. Also I have to add margin to my complete set of data shown inside DetailsFragment extends Fragment. How can this be done? Please help me out. Thanks in advance.
Please see my xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#drawable/bg"
android:orientation="vertical" >
<ListView
android:id="#+id/list_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:cacheColorHint="#00000000"
android:divider="#android:color/transparent"
android:dividerHeight="10dp"
android:scrollbars="none"
android:smoothScrollbar="true" >
</ListView>
ListViews (along with Fragments, ListFragments, etc) appear to override the provided layout's root parameters (height, width), in order to fit the predefined View/Item dimensions into the parent. This also seems to happen with each of the layout's children Maximum dimensions, for instance, the TextView from AOSP's simple_list_item_1.xml
Since you are asking specifically for ListView item spacing, I would still not use dividerHeight as suggested by blackbelt, as this would change the centering of your original content (also the first item would not have the desired spacing from the top of the list, as the divider is below each item).
For ListView items, you can generally override this behavior by setting a custom layout (called by a custom adapter) with a top and bottom margin. See the following sample based simple_list_item_1.xml and note the margin modifiers at the end:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:layout_marginTop="20dp"
android:layout_marginBottom="20dp"
/>
(you might need to provide inline values for non-public references to "?android:attr")
You would then have to call a custom adapter for your list (such as ArrayAdapter) and supply it with your custom list item XML.
You have to set the divider and the dividerHeight properties in your layout.xml file.
For instance
<ListView
android:id="#android:id/list"
android:divider="#android:color/transparent"
android:dividerHeight="5dip" />
in this way you will get all elements of the ListFragment spaced by 5 dip
