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 have a listview, when I scroll it, that time listview element background color changes to black. I tried couple of hours, but not getting solution.
I tried
android:cacheColorHint="#android:color/transparent"
or
android:cacheColorHint="#00000000"
set the
android:cacheColorHint
to the color you used as a background to the ListViewItem
In my case this works fine
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="1dip"
android:layout_weight="1"
android:background="#ffffff"
android:choiceMode="singleChoice"
android:cacheColorHint="#android:color/transparent"
android:scrollingCache="false"
android:fastScrollEnabled="true">
</ListView>
One of the developer says, you have to use these 2 properties compulsory..
android:cacheColorHint="#android:color/transparent"
android:scrollingCache="false"
You can use this code:
// you can use your color also
android:background="#android:color/transparent"
android:cacheColorHint="#android:color/transparent"
Both color should be same, then your problem will be solved.
Hope it will help you.
Add following attributes to your listview inside xml layout.
android:scrollingCache="true"
android:cacheColorHint="#ffffff"
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:

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.
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
I'm using two ListViews like this:
<ListView
android:id="#+id/ListView"
android:text="#string/Website"
android:layout_height="30px"
android:layout_width="150px"
android:scrollbars="none"
android:transcriptMode="normal"/>
<ListView
android:id="#+id/ListView1"
android:text="#string/Website"
android:layout_height="30px"
android:layout_width="150px"
android:scrollbars="none"
android:transcriptMode="normal"/>
There is one blank line between the two ListViews. How do I remove it?
To remove the separator between items in the same ListView, here is the solution:
getListView().setDivider(null);
getListView().setDividerHeight(0);
developer.android.com # ListView
Or, if you want to do it in XML:
android:divider="#null"
android:dividerHeight="0dp"
If you want to remove a divider line, use this code:
android:divider="#null"
If you want to add a space instead of a divider line:
android:divider="#android:color/transparent"
android:dividerHeight="5dp"
So, you can use any drawable or color in the divider attribute.
There are different ways to achieve this, but I'm not sure which one is the best (I don't even know is there is a best way). I know at least two different ways to do this in a ListView:
1. Set divider to null:
1.1. Programmatically
yourListView.setDivider(null);
1.2. XML
This goes inside your ListView element.
android:divider="#null"
2. Set divider to transparent and set its height to 0 to avoid adding space between listview elements:
2.1. Programmatically:
yourListView.setDivider(new ColorDrawable(android.R.color.transparent));
yourListView.setDividerHeight(0);
2.2. XML
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
Set divider to null:
JAVA
listview_id.setDivider(null);
XML
<ListView
android:id="#+id/listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#null"
/>
In XML:
android:divider="#null"
Or in Java:
listView.setDivider(null);
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#null"
android:dividerHeight="0dp"/>
You can put below property in listview tag
android:divider="#null"
(or)
programmatically listview.Divider(null);
here listview is ListView reference.
Or in XML:
android:divider="#drawable/list_item_divider"
android:dividerHeight="1dp"
You can use a color for the drawable (e.g. #ff112233), but be aware, that pre-cupcake releases have a bug in which the color cannot be set. Instead a 9-patch or a image must be used..
You can try the following. It worked for me...
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
I find it easier to implement it in the XML file as it can be harder to trace the line of code in a class with hundreds of lines.
For the XML you can use "null":
android:divider="#null"
For ListFragment use
getListView().setDivider(null)
after the list has been obtained.
If you want to remove lines from
⛔ Problem
Having lines between items from <ListView>
✅ Solution
add an attribute android:drivider="#null"
If this android:divider="#null" doesn't work, maybe changing your ListViews for Recycler Views?
String txt = ( (TextView) view).getText().toString();
adapter.remove(txt);
