I am getting the following exception:
java.lang.IllegalStateException: get field slot from row 0 col -1 failed
when I call setAdapter() on my ExpandableListView. Can someone please help me fix this problem? (I have already wasted 2 days :( )
Cursor mCursor = tasksListCursor();
Log.i("ChronicleTaskList", "rowcount: "+mCursor.getCount());
startManagingCursor(mCursor);
boolean flag = mCursor.moveToFirst();
while (flag) { // This loop executes fine.
long id = mCursor.getLong(mCursor.getColumnIndexOrThrow(ChronicleDb.KEY_ID));
String name = mCursor.getString(mCursor.getColumnIndexOrThrow(ChronicleDb.KEY_NAME));
long from = mCursor.getLong(mCursor.getColumnIndexOrThrow(ChronicleDb.KEY_FROM));
long to = mCursor.getLong(mCursor.getColumnIndexOrThrow(ChronicleDb.KEY_TO));
Log.i("ChronicleTaskList", id + ", "+ name+ ", "+ from+ ", "+to);
flag = mCursor.moveToNext();
}
String[] grpFromCols = { ChronicleDb.KEY_NAME};
int[] grpToVals = { R.id.cGroupRowTextName };
String[] fromCols = { TasksDbAdapter.KEY_TODODATE,
TasksDbAdapter.KEY_NAME };
int[] toVals = { R.id.textViewDate2, R.id.taskRowTextTask };
ChronicleTreeListAdapterSimple adapter = new ChronicleTreeListAdapterSimple(this, mCursor,
R.layout.c_group_row, grpFromCols, grpToVals,
R.layout.task_row2, fromCols, toVals, true);
expandableListView.setAdapter(adapter);
The last line throws the exception.
And the Adapter looks like this:
public class ChronicleTreeListAdapterSimple extends SimpleCursorTreeAdapter {
protected static String TAG = "ChronicleTreeListAdapter";
public ChronicleTreeListAdapterSimple(
ChronicleTaskList context, Cursor cursor,
int groupLayout, String[] groupFrom, int[] groupTo,
int childLayout, String[] childFrom, int[] childTo,
boolean showGroupName) {
super(context, cursor, groupLayout, groupFrom, groupTo, childLayout, childFrom, childTo);
taskList = context;
}
