view story

http://stackoverflow.com – I searched other topics and came to the conclusion that my listview was the cause of the null pointer exception but i cant figure anyway to fix it. here is my XML file <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ListView android:id="@+id/instantme_check_list" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_weight="2.88" > </ListView> left (HowTos)
