I want to display
ArrayAdapter<com.example.database.Sms>adapter = new SmsAdapter(this, smss);
and
ArrayAdapter<com.example.database2.part1> adapter = new DastanAdapter(this, part1);
But according to my code it shows just one of them but I want to have both of them shown
public void refreshDisplay() {
Log.i(com.example.database.DBAdapter.TAG, smss.size() + "= tedad smss");
ArrayAdapter<com.example.database.Sms>adapter = new SmsAdapter(this, smss);
setListAdapter(adapter);
}
public void refreshDisplay2() {
Log.i(DBAdapter.TAG, part1.size() + "= tedad part1");
ArrayAdapter<com.example.database2.part1> adapter = new DastanAdapter(this, part1);
setListAdapter(adapter);
}

I am quite new to this so please bear with me. I am trying to use a keyword search to pull images from twitter using twitter4j. I want it to show the images positioned randomly on the screen in a loop.
This code I have below is a combination of different ones I have found online. Its currently finding tweets using these keywords and showing them in the console, however, it is not displaying them on the screen and I’m not sure why…
Another thing is that I think it is doing a live stream from twitter so pulling tweets immediately at the time the code is run, so I am not getting lots of results when I put in an obscure keyword, I want it to search for the last 100 tweets with images using the keyword so that I get more results
I’d really appreciate all the help I can get! thank you

I have a little issue with an editable TableView. I want to display data from the database and also be able to edit then which saves it back to the DB.
Now, I can edit it. I have an if statement which checks whether the value is blank (empty or white space) and it works properly, the item in DB doesn't get updated if the value is blank.
My issue is that the blank value still gets displayed. If I click to edit it again, it displays the proper value. Here is a picture of the issue.
Here is the method which creats the table in my view class.
private TableView<Teacher> createTable(){
TableView table = new TableView();
table.setEditable(true);
table.setPrefWidth(500);
table.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
nameColumn = new TableColumn<>("Jméno");
surnameColumn = new TableColumn<>("Příjmení");
nickColumn = new TableColumn<>("Nick");
table.getColumns().addAll(nameColumn, surnameColumn, nickColumn);
int columnCount = table.getColumns().size();
double columnSize = Math.floor(table.getPrefWidth() / columnCount);
nameColumn.setPrefWidth(columnSize);
surnameColumn.setPrefWidth(columnSize);
nickColumn.setPrefWidth(columnSize);
nameColumn.setCellValueFactory(new PropertyValueFactory<>("name"));
surnameColumn.setCellValueFactory(new PropertyValueFactory<>("surname"));
nickColumn.setCellValueFactory(new PropertyValueFactory<>("nick"));
List<Teacher> list = new TeacherDao().getAllTeachers();
ObservableList<Teacher> observableList = FXCollections.observableArrayList(list);
table.setItems(observableList);
return table;
}
Here is the part of the controller class to handle the edits.
private void onEditAction(){
view.getNameColumn().setCellFactory(TextFieldTableCell.forTableColumn());
view.getNameColumn().setOnEditCommit(
new EventHandler<TableColumn.CellEditEvent<Teacher, String>>() {
#Override
public void handle(TableColumn.CellEditEvent<Teacher, String> col) {
String newValue = col.getNewValue();
if(!(CheckString.isBlank(newValue))) {
(col.getTableView().getItems().get(
col.getTablePosition().getRow())
).setName(col.getNewValue());
Teacher teacher = view.getTeacherTableView().getSelectionModel().getSelectedItem();
int id = teacher.getUser_id();
new TeacherDao().updateTeacherNick(id, newValue);
}
}
}
);
view.getSurnameColumn().setCellFactory(TextFieldTableCell.forTableColumn());
view.getSurnameColumn().setOnEditCommit(
new EventHandler<TableColumn.CellEditEvent<Teacher, String>>() {
#Override
public void handle(TableColumn.CellEditEvent<Teacher, String> col) {
String newValue = col.getNewValue();
if(!(CheckString.isBlank(newValue))) {
(col.getTableView().getItems().get(
col.getTablePosition().getRow())
).setName(col.getNewValue());
Teacher teacher = view.getTeacherTableView().getSelectionModel().getSelectedItem();
int id = teacher.getUser_id();
new TeacherDao().updateTeacherNick(id, newValue);
}
}
}
);
view.getNickColumn().setCellFactory(TextFieldTableCell.forTableColumn());
view.getNickColumn().setOnEditCommit(
new EventHandler<TableColumn.CellEditEvent<Teacher, String>>() {
#Override
public void handle(TableColumn.CellEditEvent<Teacher, String> col) {
String newValue = col.getNewValue();
if(!(CheckString.isBlank(newValue))) {
(col.getTableView().getItems().get(
col.getTablePosition().getRow())
).setName(col.getNewValue());
Teacher teacher = view.getTeacherTableView().getSelectionModel().getSelectedItem();
int id = teacher.getUser_id();
new TeacherDao().updateTeacherNick(id, newValue);
}
}
}
);
}
I also tried adding, it didn't help though.
else
(col.getTableView().getItems().get(
col.getTablePosition().getRow())
).setName(col.getOldValue());
Well, I managed to solve it, here is how if anyone is curious
public class TeacherTableView extends TableView {
private TableColumn<Teacher, String> nameColumn, surnameColumn, nickColumn;
TeacherTableView() {
createTable();
onEditAction();
}
private void createTable(){
setEditable(true);
setPrefWidth(500);

nameColumn = new TableColumn<>("Jméno");
surnameColumn = new TableColumn<>("Příjmení");
nickColumn = new TableColumn<>("Nick");
getColumns().addAll(nameColumn, surnameColumn, nickColumn);
int columnCount = getColumns().size();
double columnSize = Math.floor(getPrefWidth() / columnCount);
nameColumn.setPrefWidth(columnSize);

nameColumn.setCellFactory(TextFieldTableCell.forTableColumn());
nameColumn.setEditable(true);
surnameColumn.setPrefWidth(columnSize);

nickColumn.setCellValueFactory(cdf -> cdf.getValue().nickProperty());

nickColumn.setEditable(true);
List<Teacher> list = new TeacherDao().getAllTeachers();
ObservableList<Teacher> observableList = FXCollections.observableArrayList(list);
setItems(observableList);
}
private void onEditAction(){
nameColumn.setOnEditCommit(this::updateCol);
surnameColumn.setOnEditCommit(this::updateCol);
nickColumn.setOnEditCommit(this::updateCol);
}
private void updateCol(TableColumn.CellEditEvent<Teacher, String> col) {
String newValue = col.getNewValue();
if (CheckString.isNotBlank(newValue)) {
(col.getTableView().getItems().get(
col.getTablePosition().getRow())
).setName(col.getNewValue());
Teacher teacher = (Teacher) getSelectionModel().getSelectedItem();
int id = teacher.getUser_id();

I am writing an Opendaylight application that will extract all the flow rules as and when it is deleted, added or updated.
To get the notifications when a flow is added, removed or updated, the application should provide a listener which extends the salFlowListener interface.
However, when I create the application directory structure, it is not clear from the Opendaylight tutorials online as to where the logic is to be put.
Additionally, there are compilation errors when the notification-service is augmented using the YANG model.
Is this the right approach to getting the notifications and is any clear tutorials online that I can refer to?
Thanks.

How I do is to set the InstanceIdentifier. Setting different InstanceIdentifier, you can also listener to the change of node, table, and so on.
we've created a custom webpart to display announcements from all lists a user has access to, removing a few. The error we are having is that the webpart works fine on the page for the administrators, but when testing with regular user accounts, they are unable to see the page at all and are given a Access Denied error which is coming from the webpart itself.
Only when a user is added as a Site Collection Administrator they can see the page and have access to the webpart. What I'd like some advice on is how to be able to apply full read permissions to a select group within the code itself.

I have a java SWT application that works OK with Windows XP and Windows Vista. But when I run it on Windows 7, weird errors occure, and it crashes.
For example, in a method where I call Table.removeAll() I get a java.lang.ArrayIndexOutOfBoundsException: 0. The table has SWT.VIRTUAL in style.
Another problem is when I write something in a text box (there's a ModifyListener which filters something) - after 2 characters, the cursor moves at the beginning (before first character).
The SWT version is 3.5, but I tried with the latest from the eclipse website(3.6M3) and the result is the same.
Are there any known issues? Has anybody encountered this?
Here is a snippet that doesn't work in Windows 7:

The SWT versions I checked is (as shown in the text in the shell):
SWT win32 3550; Windows 7 6.1 x86
SWT win32 3617; Windows 7 6.1 x86
I have resolved this problem after asking the same question.
You must either remove SWT.VIRTUAL or update to the SVN build of SWT. I've posted a bug report on the SWT bug page.
Edit: your code snippet has a bug in it that is causing the ArrayIndexOutOfBoundsException. You can resolve it by changing lines containing listenerSD:
public void handleEvent(Event event) {
Collection<?> collectionW = (Collection<?>) event.widget
.getData(DATA_COLLECTION);
if (collectionW.size() > event.index) {
Object object = collectionW
.toArray(new Object[collectionW.size()])[event.index];
((TableItem) event.item).setText(0, object
.toString());
}
}
On Windows 7, the table updates the visible items immediately when clearAll() is called. So
table.clearAll();
must be after the line
table.setItemCount(collection.size());
