I am trying to move between 3 forms. 1 is main form and 2 other simple forms.
I have commands in the soft keys but they are not working...
below is my code...
public class checkOutComponents extends MIDlet implements ActionListener
{
private Form appForm;
private Form f1;
private Form f2;
Command GoTof1 = new Command("GoTof1");
Command GoTof2 = new Command("GoTof2");
Command GoToMainForm = new Command("GoToMainForm");
public void startApp()
{
Display.init(this);
appForm = new Form("Check These Components!! ");
appForm.setLayout(new BorderLayout());
appForm.addCommand(GoTof1);
appForm.addCommand(GoTof2);
appForm.addComponent(BorderLayout.CENTER, formContainer);
appForm.show();
}
public void pauseApp()
{
}
public void destroyApp(boolean unconditional)
{
}
public void actionPerformed(ActionEvent event)
{
Command eventCmd = event.getCommand();
Form f = Display.getInstance().getCurrent();
boolean sentido = false;
if (eventCmd == GoTof1)
{
sentido = true;
Image i1 = null;
try
{
i1 = Image.createImage("/hello/1.jpeg");
}
catch (IOException ex)
{
ex.printStackTrace();
}
Label lab1 = new Label(i1);
f1.addComponent(lab1);
f1.addCommand(GoTof2);
f1.addCommand(GoToMainForm);
f.setTransitionOutAnimator(Transition3D.createCube(300, sentido));
f1.show();
}
else if (eventCmd == GoTof2)
{
sentido = false;
Image i2 = null;
try
{
i2 = Image.createImage("/hello/2.jpeg");
}
catch (IOException ex)
{
ex.printStackTrace();
}
Label lab2 = new Label(i2);
f1.addComponent(lab2);
f1.addCommand(GoTof1);
f1.addCommand(GoToMainForm);
f.setTransitionOutAnimator(Transition3D.createCube(300, sentido));
f2.show();
}
else if(eventCmd == GoToMainForm)
{
appForm.showBack();
}
}
}
Kindly help regarding this.
Thanks in advance and regards,
Swati
Add command listener to the form appForm.
appForm.addCommandListener(this);

The AutoCompleteTextField seems to work exactly as intended until I start backspacing in the TextField. I am not sure what the difference is, but if I type in something like "123 M" then I get values that start with "123 M". If I backspace and delete the M leaving "123 " in the field, the list changes, but it does not scroll to the top of the list.
I should note that everything works fine on the simulator and that I am experiencing this behavior when running a debug build on my iPhone.
EDIT: So this does not only seem to happen when backspacing. This image shows the results I have when typing in an address key by key. In any of the pictures where the list isn't viewable or is clipped, I am able to drag down on the list to get it to then display properly. I have not tried this on an Android device.

I was able to create this issue but not the issue you describe.
This is a service running in the background, no Activity, began operating normally, but After about four hours, there will be a ConnectTimeoutException.
Connect to xxx.xxx.xxx.xxx time out.
This problem occurs in Android 6, I did not find this issue Android 4. When this problem occurs, I have to restart this phone, after which it connects properly for some time. When this problem occurs, other network applications on the phone runs properly.

I am creating javafx application where I have this case that I need to listen for data sent over Bluetooth.
I have one fxml window on which I need to initialize Bluetooth and start listening from data.
Following is my Code for fxml controller:
//all imports
public class NewBarcodeInvoicePaneController implements Initializable{
private BluetoothController bc;
public BluetoothController getBc() {
return bc;
}
#Override
public void initialize(URL location, ResourceBundle resources) {
try {
bc = new BluetoothController();
new Thread(bc).start();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
And BluetoothController is task where I initialize bluettoth and listen to the data
public class BluetoothController extends Task<Void> {
#Override
protected Void call() throws Exception {
LocalDevice local = null;
StreamConnectionNotifier notifier;
StreamConnection connection = null;
// setup the server to listen for connection
try {
local = LocalDevice.getLocalDevice();
try {
local.setDiscoverable(DiscoveryAgent.GIAC);
} catch (BluetoothStateException e) {
}
UUID uuid = new UUID(80087355); // "04c6093b-0000-1000-8000-00805f9b34fb"
String url = "btspp://localhost:" + uuid.toString() + ";name=RemoteBluetooth";
notifier = (StreamConnectionNotifier) Connector.open(url);
} catch (Exception e) {
e.printStackTrace();
return null;
}
try {
System.err.println("THIS IS HAPENING");
connection = notifier.acceptAndOpen();
System.err.println("HAPENING???????????????????????????");
InputStream inputStream = connection.openInputStream();
BufferedReader bReader = new BufferedReader(new InputStreamReader(inputStream));
String lineRead = bReader.readLine();
connection.close();
inputStream.close();
notifier.close();
local.setDiscoverable(DiscoveryAgent.NOT_DISCOVERABLE);
JSONParser parser = new JSONParser();
Object obj = parser.parse(lineRead);
JSONArray array = (JSONArray) obj;
array.stream().map((o) -> (String) o).forEach((stringObj) -> {
System.out.println(stringObj);
});
System.out.println("AFTER DATA RECIEVED");
} catch (Exception e) {
e.printStackTrace();
return null;
}
return null;
}
}
It Works fine if I send data over bluetooth and blocking call to notifier.acceptAndOpen() is unblocked.
My problem is when we do not pass any data and I just want to close the window I opened..
It still have blocking call open with extra thread by the task.
I tried to cancel BluetoothController task in Main controller where I open this window like following
private void openNewBarcodeInvoicePane(ActionEvent ae) {
//following are custom classes to open windows from fxml and getting controller back for further manipulation
PostoryModalWindow modalWindow = new PostoryModalWindow();
modalWindow.openNewModalPaneWithParent("New Invoice", "fxml/newbarcodeinvoicepane.fxml", ae);
//getting controller object
NewBarcodeInvoicePaneController controller = (NewBarcodeInvoicePaneController) modalWindow.getDswFromController();
controller.getWindowStage().showAndWait();
BluetoothController bc = controller.getBc();
if(bc != null){
System.err.println("CANCELLING");
bc.cancel(true);
}
}
But it doesn't throw InterrupttedExeption (In which I might have Choice to close Bluetooth thread) and after research I found that waiting on Socket doesn't work on interrupt.
Any help on this?
Thanks
Got Solution After Some Research.
I just added new task to call notifier.acceptAndOpen();
And added method to close Bluetooth notifier.
public class BluetoothController extends Task<Void> {
private final ObservableList<Item> items = FXCollections.observableArrayList();
public ObservableList<Item> getItems() {
return items;
}
StreamConnectionNotifier notifier;
#Override
protected Void call() throws Exception {
try {
BluetoothConnectionTask bct = new BluetoothConnectionTask(items);
new Thread(bct).start();
Thread.sleep(2000);
notifier = bct.getNotifier();
} catch (Exception e) {
e.printStackTrace();
return null;
}
return null;
}
public void cancelandExit() {
try {
if (notifier != null) {
notifier.close();
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
Here is new task for blocking call
public class BluetoothConnectionTask extends Task<Void>{
private StreamConnectionNotifier notifier;
private StreamConnection connection;
private ObservableList<Item> items = FXCollections.observableArrayList();
public StreamConnection getConnection() {
return connection;
}
public StreamConnectionNotifier getNotifier() {
return notifier;
}
public BluetoothConnectionTask(ObservableList<Item> is){
items = is;
}
#Override
protected Void call() throws Exception {
try {
LocalDevice local = LocalDevice.getLocalDevice();
try {
local.setDiscoverable(DiscoveryAgent.GIAC);
} catch (BluetoothStateException e) {
}
UUID uuid = new UUID(80087355); // "04c6093b-0000-1000-8000-00805f9b34fb"
String url = "btspp://localhost:" + uuid.toString() + ";name=RemoteBluetooth";
notifier = (StreamConnectionNotifier) Connector.open(url);
} catch (Exception e) {
e.printStackTrace();
return null;
}
connection = notifier.acceptAndOpen();
InputStream inputStream = connection.openInputStream();
BufferedReader bReader = new BufferedReader(new InputStreamReader(inputStream));
String lineRead = bReader.readLine();
connection.close();
inputStream.close();
notifier.close();
LocalDevice local = LocalDevice.getLocalDevice();
local.setDiscoverable(DiscoveryAgent.NOT_DISCOVERABLE);
JSONParser parser = new JSONParser();
Object obj = parser.parse(lineRead);
JSONArray array = (JSONArray) obj;
ItemDAO idao = new ItemDAO();
array.stream().map((o) -> (String) o).forEach((stringObj) -> {
String barcode = (String) stringObj;
Item i = idao.getItemByBarCode(barcode);
System.err.println("Adding Item "+i.getName());
items.add(i);
});
System.out.println("AFTER DATA RECIEVED");
return null;
}
}
Now for cancelling closing my bluetooth thread I am calling cancelandExit() after window is closed.
I'm trying to remove this select area which shows up as soon as I add a button to my form.
Have attached a screenshot of the same which might help you understand my plight here. I don't want this select area to appear at the bottom of screen.
Please, any suggestion or any pointer would be of great help.
regards.
Below is the code which I'm using.(Xlet project)
public void showMainForm() {
try {
mf = new MainForm();
mf.createMainForm();
mf.show();
} catch (Exception e) {
}
}
public class MainForm extends Form {
MainForm() {
super();
}
private static Container c;
public void createMainForm() {
try {
c = new Container(new CoordinateLayout(800,480));
Button btn = new Button();
btn.setX(0); btn.setY(0);
c.addComponent(btn);
this.getContentPane().addComponent(c);
} catch (Exception e) {
}
}
}
Form code which I tried again...
Form frm = new Form();
frm.getStyle().setBgTransparency(0);
//frm.addComponent(new Button("Button"));
frm.show();
I think that this issue can be solved adding the Command to the Form,not to the Container as you are doing in the attached code.
ADD
I think that I didn't understand what you want to say. Try this code, with my suggestions included
public void showMainForm() {
try {
mf = new MainForm();
mf.createMainForm();
mf.show();
} catch (Exception e) {
}
}
public class MainForm extends Form {
MainForm() {
super();
}
private static Container c;
public void createMainForm() {
try {
c = new Container(new CoordinateLayout(800,480));
// Button btn = new Button();
// btn.setX(0); btn.setY(0);
// c.addComponent(btn);
// this.getContentPane().addComponent(c);
Command c = new Command("command");
addCommand(c);
} catch (Exception e) {
}
}

The best way to do this is using dynamic resources. I'll suggest you to read chapter "Resource managment with Wicket" of this magnific free Wicket guide: https://code.google.com/p/wicket-guide/.
Here you have a similar example given in this guide in the section "Custom resources".
public class RSSProducerResource extends AbstractResource {
#Override
protected ResourceResponse newResourceResponse(Attributes attributes) {
ResourceResponse resourceResponse = new ResourceResponse();
resourceResponse.setContentType("text/xml");
resourceResponse.setTextEncoding("utf-8");
resourceResponse.setWriteCallback(new WriteCallback()
{
#Override
public void writeData(Attributes attributes) throws IOException
{
OutputStream outputStream = attributes.getResponse().getOutputStream();
Writer writer = new OutputStreamWriter(outputStream);
SyndFeedOutput output = new SyndFeedOutput();
try {
output.output(getFeed(), writer);
} catch (FeedException e) {
throw new WicketRuntimeException("Problems writing feed to response...");
}
}
});
return resourceResponse;
}
// method getFeed()...
}
And then you need to add the link in the desired page or component:
add(new ResourceLink("rssLink", new RSSProducerResource()));
