I’ve created an android application with a ListView. I’ve added both a header and footer to the list. But when adding a divider/separator it also creates an empty space between the header and the first ListView item. It does the same for the last ListView item and the footer.
The empty space is equivalent to the size of the divider between all the ListView items, with the difference that it doesn’t draw the divider and just leaves empty space. I thought I found the solution with the xml attributes ‘Footer dividers enabled’ and ‘Header dividers enabled’. But when setting them to false, it doesn’t change anything. I even tried to set them programmatically with
But it just doesn’t work. Any way to fix that problem? I just don’t want the empty space to be there, I want the first item to fit exactly to the header (same for the footer).
I stumbled upon the same problem, but in a slightly different situation than yours. My
ListView has a header (a search box), but the first item below it contains a section header (a date, or a letter) rather than being a regular list item (with the actual content in form of an image, some text, and so on). As such, I want it not to be selectable, so in my custom adapter I have overridden
areAllItemsEnabled to return
Big mistake, because that’s exactly the culprit. See, it appears that, by design, the
ListView implementation only draw dividers between two enabled items, but still reserve space for dividers between an enabled item and a disabled one even if those dividers will not be drawn. The fact this is a conscious design decision does not mean it’s not stupid, of course. Most weird of all, this dividers drawing policy is based just on the value returned by
areAllItemsEnabled instead of the values returned by single calls to
isEnabled for subsequent items.
Thus, to work around it, I just had to return
areAllItemsEnabled (I kept the overridden method and add a comment about this issue, otherwise I would not be able to remember it a month from now): lo and behold, white space disappeared, replaced by a divider. Now, if I want to show the
ListView header and the first section header as being exactly adjacent, I just have to choose a divider color that’s the same as the section header color.
Really hope that’s the same case as yours, or that my solution helps you in some other way.
View Layout (header.xml):
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" > <RelativeLayout android:id="@+id/content" android:layout_width="fill_parent" android:layout_height="wrap_content" > <ProgressBar style="@android:style/Widget.ProgressBar.Small.Inverse" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:layout_margin="16dp" android:layout_marginTop="2dp" /> </RelativeLayout> </LinearLayout>
m_headerView = inflater.inflate(R.layout.header, this, false);
m_headerView.setPadding(0, 0, 0, 0); m_headerView.setVisibility(View.VISIBLE);
m_headerView.setPadding(0, -1000, 0, 0); m_headerView.setVisibility(View.GONE);
It worked perfectly in our project. I hope it is helpful.
In getview method you can check if the item is first or last and set custom devider which will be of 0 height or single pixel height of transparent color.
goto the ListView properties in android layout and search for spacing tag… some how in android, when creating new layouts, it will defaults creation is spacing header spacing and border properties. check it , if it is available then remove it
Didn’t find a great solution.
dividerHeight="0dp" and created my own dividers manually – either directly in the layout XML or dynamically in the adapter if you need more precise control.
That should take care of it.
