Hi,
I try to explain my problem hope someone can help me point out the causes.
I have a TabActivity that has 2 Tabs "MainApp.java" and "MethodB.java".
MethodB has code to populate a List, MainApp also populate the same content
but
filter out some column so from MainApp I call the method
MethodB.Test(String).
I cannot get the list populated. If I tab on Tab "MethodB" first and return
to MainApp Tab
I got the list content correctly display in MainApp.
-----MainApp.java------------------------------------------------------------------------------------------------------
/*
If I call Test(String) in MainApp "(MethodB.Test(String)", the listview is
empty, if the list has been preciously initialise
in MethodB not calling from MapApp, the list is populated and if I call
Test(String) now in
MainApp the list is good.
*/
-----MethodB.java------------------------------------------------------------------------------------------------------
/*
The Test(String) can correctly populate InitialiseListView
*/
private static void InitialiseListView() {
events = new PasswordEventsData(mainContext);
try {
Cursor cursor = getEvents();
showEvents(cursor);
} finally {
events.close();
}
}
private static Cursor getEvents() {
//Perform a managed query. The Activity will handle closing
//and re-querying the cursor when needed.
SQLiteDatabase db = events.getReadableDatabase();
Cursor cursor = db.query(TABLE_NAME, FROM, null, null, null, null,
ORDER_BY);
((Activity) mainContext).startManagingCursor(cursor);
return cursor;
}
private static void showEvents(Cursor cursor) {
//Set up data binding
SimpleCursorAdapter adapter = new SimpleCursorAdapter(mainContext,
R.layout.itemname, cursor, FROM, TO);
((ListActivity) mainContext).setListAdapter(adapter);
adapter.notifyDataSetChanged();
}
public static void Test(String Type) {
InitialiseListView();
}
