In short, is it possible to tell a child in a RelativeLayout
to always match the height of that RelativeLayout
regardless of how other children in that same RelativeLayout
behave? In short, that's it. Details below.
What I'm trying to achieve is a ListView
row with at least three views, and one of those views would be kind of a stripe at the right side of the list entry (the red view below). The problem I'm having is that there is a TextView
at the left side, and depeding on how much text I have, the stripe won't fill the whole layout. This is very clearly explained by images below.
ListView
item layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<View
android:id="@+id/bottom_line"
android:layout_width="match_parent"
android:layout_height="5dp"
android:layout_alignParentBottom="true"
android:background="#fc0" />
<!-- Why match_parent does not work in view below? -->
<View
android:id="@+id/stripe"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:minHeight="50dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:background="#f00" />
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="@id/stripe"
android:text="This is a very long line, meant to completely break the match_parent property of the box at right"
style="?android:textAppearanceLarge"/>
</RelativeLayout>
Result:
match_parent
makes no difference. I did it.Repeating the question, I want the red stripe to always fill the parent vertically. You can see stripe is not aligning to the top of root.
A note: the above example is the simplest, self-contained example I can think of. It's just a ListActivity
with an anonymous ArrayAdapter
populated by a static String
array. The relevant code in onCreate
is at most 8 lines, so no worries there. It's really the layout. Besides, I have this working with nested LinearLayout
s already, but I'm trying to reduce the depth of my layout structure a bit, if possible. LinearLayout
works fine, as expected.
I had the same requirement and my solution was to align the top of the red stripe to the parent's top, and the bottom of the stripe to the bottom of the text view on the left. The height in this case becomes irrelevant. You can either use wrap_content
or match_parent
.
