I want to add the popup to an existing functionality of backoffice. When a user click on the icon a popup will be populated with a text box and submit button.
I have tried many things but still can't find any proper solution. Help me in that to resolve the issue.
Create a new class that extends org.zkoss.zul.Window Class :
public class CustomWindow extends Window {
}
Then create a render method and add your components :
public class CustomWindow extends Window {
public void render(WidgetInstanceManager wim) {
initComponent(wim);
final Vlayout container = new Vlayout();
final Labeltext =new Label("text");
final Button button = new Button("button");
container.appendChild(button);
container.appendChild(text);
this.appendChild(container);
setClosable(true);
}
}
Then you can open your custom window with :
CustomWindow customWindow = new CustomWindow ();
customWindow.render(getWidgetInstanceManager());
customWindow.setParent("add parent component here");
customWindow.doModal();
Adapt the code to correspond more to your needs.
Hope this helps.

I have an Android application with a dialog and a few buttons inside.
I want to reuse the dialog for different purposes and looking for a way to call the button from a separate class and define an action event for it.
Creating a test class, I managed to define an action event for a button inside a form, but the same code does not work for a button inside a dialog, and I can't get my head around why it is not working for the dialog.
Below is what I already have. Any suggestions would be appreciated.
public Class One {
Test test = new Test();
test.testOne(); // this is working : button prints
test.testTwo(); // this is not working : button does not print
buttonTest = test.getTestButton();
buttonTest.setText("Hello World"); // not working for a button in a dialog
buttonTest.addActionListener(l-> { // prints when the button in a Form
System.out.println("try"); // does not print when the button is in a dialog
});
}
public class Test {
Dialog dialog = new Dialog();
Form form = new Form();
Button button;
public void testOne() {
button = new Button("Test");
form.add(button);
form.show();
}
public void testTwo() {
button = new Button("Testing");
dialog.add(button);
dialog.show();
}
public Button getTestButton () {
return button;
}
}
You add the action listener after showing the form and dialog. This isn't a problem for the form since the forms show method will continue. But a dialogs show() method will block.
Two solutions:
Move the listener binding higher in the code (before the show) that would be a problem since the button doesn't exist yet so you will need some refactoring.
Change the show() call on the dialog to showModless()
To illustrate what I mean with this, it is similar to WhatsApp, where various options are displayed in the toolbar when a chat is selected.
I have a similar layout, so a MainActivity with Fragments containing RecyclerViews. Now when an item in a RecyclerView is selected I would like to get a similar behaviour as in WhatsApp. The RecyclerViews have an Adapter that implements an OnClickListener.
However, from this Adapter I do not seem to have access to Views from the MainActivity. I tried the following (inside the OnClick method in the Adapter), but it did not work since the view could not be found.
View view = getActivity().findViewById(R.id.toolbar_main_activity);
if( view instanceof Toolbar) {
Toolbar toolbar = (Toolbar) view;
toolbar.setTitle("TestTitle");
}
Does anyone know how to get the intended behavior or have a reference to a tutorial?
UPDATE: for who is also stuck with this and this is still quite confusing, here is how I solved it in my own words
My Fragment contains the Interface by adding the following code to it;
OnItemsSelected mCallBack;
public interface OnItemsSelected {
void onToolbarOptions(String title);
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
mCallback = (OnItemsSelected) getActivity();
}
Also I passed 'mCallback' to the adapter like this;
MyAdapter adapter = new MyAdapter(myList, mCallback);
The RecyclerView adapter implements OnClickListener. In the OnClick method I called; 'mCallBack.onToolbarOptions("someTitle");'. And finally I made my MainActivity implement the method; 'implements myFragment.onItemsSelected' and I added the following code to it also;
#Override
public void onToolbarOptions(String title) {
toolbar.setTitle(title);
}
With this, only the title is changed, but from this it is quite easy to make other changes to the toolbar, such as changing the menu items.
Inside your Fragment you make an Interface and a global variable like this:
OnItemsSelected mCallBack;
public interface OnItemsSelected {
public void onToolbarOptions();
}
Then when in your RecyclerView items are selected or clicked you call:
mCallBack.onToolbarOptions();
In your Activity implement the Interface like this plus the method onToolbarOptions():
public static class YourActivityName extends AppCompatActivity
implements YourFragmentName.OnItemsSelected {
public void onToolbarOptions(){
// CHANGE YOUR TOOLBAR HERE
}
//.....OTHER STUFFS IN YOUR ACTIVITY
}
I'm new in the android world but I got experience in java.
Im trying to show a dialog when I select an especific item in my spinner but, when I do it, my application has stopped.
I have 1 fragment and 1 class for the listener, instantiate an object from the fragment in the listener and try to call the dialog.
The code is somthing like this:
//Instantiate of class Guardar extends SherlockFragment.
Guardar controlador = new Guardar();
public void onItemSelected(final AdapterView parent, View view, int pos,long id) {
String addSM = parent.getItemAtPosition(pos).toString();
if (addSM == “Anyadir”){
// custom dialog
final Dialog dialog = new Dialog(controlador.context);
dialog.setContentView(R.layout.dialog_afegirsuper);
dialog.setTitle(“Title…”);
// set the custom dialog components – text, image and button
TextView text = (TextView) dialog.findViewById(R.id.text);
text.setText(“Android custom dialog example!”);
Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);
// if button is clicked, close the custom dialog
dialogButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
}
}
Is this possible to implement? another similar idea?
thanks a lot for any solution
I have a vaadin application that redirect after login to a view with header / left menu and a main panel.
how can I set the menu or any link to switch the main panel according to a specific contents
If I click contact It set ContactLayout in the main panel.
PS: I know how to set a menu like in vaadin documentation but I want to know what to set as command for the menu item.
thanks
I suggest you to keep a Map<MenuItem,AbstractLayout> and when a MenuItem is clicked, remove all the components of your Panel, and add the layout get from the Map.
Visually :
public class TestApplication extends Application {
private VerticalLayout contactLayout;
private Panel mainPanel;
Map<MenuItem, AbstractLayout> swapContentMap;
#Override
public void init() {
Window mainWindow = new Window("Test Application");
mainPanel = new Panel("Main Panel");
mainWindow.addComponent(mainPanel);
// Create all of your layout
// For now, I just create a fake contact layout
contactLayout = new VerticalLayout();
// Here add your default layout to the right panel
mainPanel.addComponent(contactLayout);
Command myCommand = new MyCommand();
MenuBar menuBar = new MenuBar();
MenuItem menuItem = menuBar.addItem("Contact", myCommand);
//add your other menu item
swapContentMap = new HashMap<MenuBar.MenuItem, AbstractLayout>();
swapContentMap.put(menuItem, contactLayout);
//add your other menu item to the map.
setMainWindow(mainWindow);
}
private class MyCommand implements Command
{
public void menuSelected(MenuItem selectedItem)
{
TestApplication.this.mainPanel.removeAllComponents();
TestApplication.this.mainPanel.addComponent(swapContentMap.get(selectedItem));
}
}
}
Hope it will work.

I am working on a game where I am extending the view and performing operations in the class. I need to have a popup in the game which will have 3 buttons inside it. I have managed to have the popup show-up using custom dialogs but when I configure the onClick as follows:
private void popUp() {
Context mContext = getContext();
Dialog dialog = new Dialog(mContext);
dialog.setContentView(R.layout.custom_fullimage_dialog);
dialog.setTitle("Cheese Market");
Button one = (Button)findViewById(R.id.firstpack);
one.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
cheeseLeft = cheeseLeft + 10;
masterMoveLock = false;
return;
}
});
}
It force closes giving a nullpointerexeption even though it is defined in the custom_fullimage_dialog layout.
Can someone help me figure out how to have the button click detected in this scenario?
Thank you.
Try calling dialog.findViewById instead.
You're setting the contentView for the dialog, but by calling findViewById you're looking for it under your activity's content view.
