How can I set the width of my custom ListView divider, in order to have it smaller than my row width?
Make a 9 patch png that has transparent pixels on the left and right. For example, a 53×4 .9.png that has 25 transparent pixels either side (+ pixels to 9patch it) would stretch the 1 pixel out so there is 25 pixels either side of it.
RecyclerView is generally preferred over using a
ListView now. See this Q&A for how to set the width of the divider in a
<inset xmlns:android="http://schemas.android.com/apk/res/android" android:insetLeft="10dp" android:insetRight="10dp" > <shape android:shape="rectangle" > <solid android:color="@color/list_divider_color" /> </shape> </inset>
And in your layout:
<ListView android:id="@+id/listView1" android:layout_width="match_parent" android:layout_height="match_parent" android:cacheColorHint="#00000000" android:divider="@drawable/list_divider" android:dividerHeight="1dp" > </ListView>
If you don’t want to make 9 patch, then you can insert
in your xml code of list_item. It creates a blue line and you can easily control the width of this line.
To make this successful you would have to disable the divider of the listview . Which is given here
You should be able to call
And pass it a drawable that you can include in your res/drawable folders. If you want to make it go almost all the way across you could just make a 9 patch that contains a horizontal line with as much transparency on the left and right sides as you want. And set it to stretch the middle portion of the line.
