Margin on ListView items in android

Posted by: admin April 23, 2020 Leave a comment

Questions:

I’m trying (in vain) to add margins to my ListView items. I have tried adding margin values to my RelativeLayout below but no matter what I do all I seem to get is a 1px line between each item.

What I really would like is to have rounded corners on each item, a 1px black border and a 3-5px margin left, top, and right but right now I’ll settle for just a margin around each item 🙂

How do I achieve my goals? Just the margin for now… 😉

Here’s what I have:

UPDATE: I have updated the xml below removing main layout and fragment layout. I have also updated the ListView item layout to what I have now which is closer to what I want but still not perfect. Screenshot added as well

listview item layout xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="@dimen/matchMargin"

    </LinearLayout>

</RelativeLayout>

</RelativeLayout>

This gives me the following where you’ll notice a very small line to the right and left for each item. That I would also like to get rid of.

How to&Answers:

I’m not great with layouts, but I have noticed in the past that ListView rows often ignore LayoutParams. I have no idea where this happens or if it’s possible to override, I do know you can easily work around it by adding another layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:background="#990000ff" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginRight="10dp"
        android:layout_marginTop="10dp"
        android:background="#9900ff00"
        android:paddingLeft="10dp" >

        <TextView
            android:id="@+id/text"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#99ff0000" />
    </LinearLayout>

</LinearLayout>

Typically layouts that only have one child can be removed, but as you can see this one serves a purpose:

Screen Shot

The outer-most layout is blue, the TextView is red, and the green is the extra layout that allows you to add some extra spacing. Notice the difference between padding (the green on the left) and margin (no green on the right). You have clearly stated that you want to use margins (android:layout_margin) but your code clearly uses padding (android:padding) so I included both.

Answer:

A little late seeing this, but just add the following lines to your ListView xml element

android:divider="#00000000"
android:dividerHeight="10dp"

Answer:

See the answer here for why. In short the child asks the parent, and the list view row uses AbsListView.LayoutParams, which doesn’t include margins.

Why LinearLayout's margin is being ignored if used as ListView row view

Answer:

In your adapter, catch your relative layout in getView(), then give a layout params ,

RelativeLayout.LayoutParams params = (RelativeLayout.LayoutParams)view.getLayoutParams();
params.setMargins(80, 0, 0, 0); //substitute parameters for left, top, right, bottom
YourRelativeLayoutInAdapter.setLayoutParams(params);

Answer:

I suppose you have a ListView defined in an XML file somewhere, if so, you could add some padding to it, so that there will be some space between the edge of the screen and the ListView.

Example:

<ListView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="15dp"/>
