i think has activity_workouts.xml

i tried changing framelayout no fragment , still loads list, still crash on rotate.

any suggestions?

thanks!

i changed activity_workouts.xml from:

<?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="fill_parent" android:orientation="horizontal" > <fragment android:id="@+id/workoutslistfragment" android:layout_width="0dp" android:layout_weight="1" android:layout_height="match_parent" class="com.rcd.mypr.workouts.workoutsfragment" ></fragment> </linearlayout>

to:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/workoutslistfragment" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" > </linearlayout>
