Crash in RelativeLayout.onMeasure()

[androidmoney]

I had the following layout for my header:

<RelativeLayout android:id="@+id/date_header_group"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

    <TextView android:id="@+id/date_header"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_centerHorizontal="true"
              android:layout_alignParentTop="true"
              android:paddingLeft="5dp"
              android:paddingRight="5dp"/>                      

    <View android:layout_width="0px"
          android:layout_height="2dp"
          android:layout_centerVertical="true"
          android:layout_alignParentLeft="true"
          android:layout_toLeftOf="@+id/date_header"
          android:background="@drawable/divider_horizontal_dark_opaque"/>

    <View android:layout_width="0px"
          android:layout_height="2dp"
          android:layout_centerVertical="true"
          android:layout_alignParentRight="true"
          android:layout_toRightOf="@+id/date_header"
          android:background="@drawable/divider_horizontal_dark_opaque"/>
</RelativeLayout>

<com.actionbarsherlock.internal.widget.CapitalizingTextView
          android:id="@android:id/text1"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:paddingLeft="10dp"
          style="?android:attr/listSeparatorTextViewStyle"/>        

When I used this layout as a header, I got a crash:

java.lang.NullPointerException
at android.widget.RelativeLayout.onMeasure(RelativeLayout.java:523)
at android.view.View.measure(View.java:15513)
at com.emilsjolander.components.stickylistheaders.StickyListHeadersListView.measureHeader(StickyListHeadersListView.java:253)

at android.widget.AbsListView.onLayout(AbsListView.java:1994)
at com.emilsjolander.components.stickylistheaders.StickyListHeadersListView.onLayout(StickyListHeadersListView.java:112)

I fixed it by changing the RelativeLayout to a FrameLayout, which it should have been anyhow, but the point remains that it should not crash.

No idea why this got cut off:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:layout_width="match_parent"
         android:layout_height="wrap_content">

<RelativeLayout android:id="@+id/date_header_group"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

    <TextView android:id="@+id/date_header"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_centerHorizontal="true"
              android:layout_alignParentTop="true"
              android:paddingLeft="5dp"
              android:paddingRight="5dp"/>                      

    <View android:layout_width="0px"
          android:layout_height="2dp"
          android:layout_centerVertical="true"
          android:layout_alignParentLeft="true"
          android:layout_toLeftOf="@+id/date_header"
          android:background="@drawable/divider_horizontal_dark_opaque"/>

    <View android:layout_width="0px"
          android:layout_height="2dp"
          android:layout_centerVertical="true"
          android:layout_alignParentRight="true"
          android:layout_toRightOf="@+id/date_header"
          android:background="@drawable/divider_horizontal_dark_opaque"/>
</RelativeLayout>

<com.actionbarsherlock.internal.widget.CapitalizingTextView
          android:id="@android:id/text1"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:paddingLeft="10dp"
          style="?android:attr/listSeparatorTextViewStyle"/>        
</RelativeLayout>

Nice catch, very weird though. This will hopefully have fixed itself in the
rewrite I am working on.

[emilsjolander]

could you please test this with the current version? probably not an issue anymore :)

[androidmoney]

I will try in a few days (I am on vacation now), but if there really is an issue with setting an adapter without data, please address that as I do that quite a bit in my app.

[emilsjolander]

of course, i also do this often

[emilsjolander]

setting the adapter with no info is now working. Get back to me when you have had a chance to try this issue with the newest build :)

[androidmoney]

This is fixed.

[emilsjolander]

thx!

I got the same issue again. Using a RelativeLayout as a header seems to be problematic! Don't know why. My RelativeLayout is very simple - contains only 2 TextViews one left aligned, one right aligned.
I got exactly the same stack trace as described here with the latest version of your library...
