I'm trying to implement Menu with select box which sets to display or not component. I have this checkbox:
final CheckMenuItem toolbarSubMenuNavigation = new CheckMenuItem("Navigation");
toolbarSubMenuNavigation.setOnAction(new EventHandler<ActionEvent>()
{
#Override
public void handle(ActionEvent e)
{
DataTabs.renderTab = toolbarSubMenuNavigation.isSelected();
// call here the getter setter and send boolean flag
System.out.println("subsystem1 #1 Enabled!");
}
});
And I have this tabpane which I want to render only if I have selected the checkbox:
public static boolean renderTab;
public DataTabs()
{
}
public boolean isRenderTab()
{
return renderTab;
}
public void setRenderTab(boolean renderTab)
{
this.renderTab = renderTab;
}
// below this code
tabPane.setVisible(renderTab);
When I run the code it's not working. I also tested this:
DataTabs tabs = new DataTabs(); // instantiate first
tabs.setRenderTab(toolbarSubMenuNavigation.isSelected());
public static boolean renderTab;
TabPane tabPane = new TabPane();
public DataTabs()
{
}
public boolean isRenderTab()
{
return renderTab;
}
public void setRenderTab(boolean renderTab)
{
tabPane.setVisible(renderTab);
}
But again there is no result when I run the code and I check or uncheck the checkbox.
This is the complete source code:
http://pastebin.com/tkj4Fby1
Maybe I need to add listener or something else which I'm missing?
EDIT
Test 3
I also tested this code:
final CheckMenuItem toolbarSubMenuNavigation = new CheckMenuItem("Navigation");
toolbarSubMenuNavigation.setOnAction(new EventHandler<ActionEvent>()
{
#Override
public void handle(ActionEvent e)
{
DataTabs.toolbarSubMenuNavigation = toolbarSubMenuNavigation;
// call here the getter setter and send boolean flag
System.out.println("subsystem1 #1 Enabled!");
}
});
// class with tabs
public static CheckMenuItem toolbarSubMenuNavigation;
public static CheckMenuItem getToolbarSubMenuNavigation()
{
return toolbarSubMenuNavigation;
}
public static void setToolbarSubMenuNavigation(CheckMenuItem toolbarSubMenuNavigation)
{
DataTabs.toolbarSubMenuNavigation = toolbarSubMenuNavigation;
}
// below
abPane.visibleProperty().bind(toolbarSubMenuNavigation.selectedProperty());
I get NPE when I run the code.
You can easely tell to your tab to be visible when you check the box in one line
yourTab.visibleProperty().bind(yourCheckBox.selectedProperty());
And just with this line your tabpane will be visible only when it's checked

I'm developping an application, and now, I don't know what to do next:
I have a list of elements, each element has some informations + an ID + a logo.
What I want to do is creating a list like in the picture
List
Of course, I want it in a single layer, with the logo, some informations, and a button to define an action; where I could use the ID of the selected item.
I did some research, may be I found some relative subjects, but none of what I want.
My list is a
ArrayList<ArrayList<String>>
filled by data from database.
Thank you
Here it is:
public class Avancee extends Activity {
// Log tag
private static final String TAG = MainActivity2.class.getSimpleName();
// Movies json url
private static final String url = "http://blabla.com/movie.json";
private ProgressDialog pDialog;
private List<Movie> movieList = new ArrayList<Movie>();
private ListView listView;
private CustomListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.list);
adapter = new CustomListAdapter(this, movieList);
listView.setAdapter(adapter);
pDialog = new ProgressDialog(this);
// Showing progress dialog before making http request
pDialog.setMessage("Loading...");
pDialog.show();
// changing action bar color
getActionBar().setBackgroundDrawable(
new ColorDrawable(Color.parseColor("#1b1b1b")));
// Creating volley request obj
JsonArrayRequest movieReq = new JsonArrayRequest(url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
//Log.d(TAG, response.toString());
hidePDialog();
String result = getIntent().getStringExtra("ITEM_EXTRAA");
System.out.println(result);
try{
JSONArray ja = new JSONArray(result);
for (int i = 0; i < ja.length(); i++) {
try {
JSONObject obj = ja.getJSONObject(i);
Movie movie = new Movie();
movie.setTitle(obj.getString("title"));
movie.setLocation(obj.getString("location_search_text"));
movie.setId(obj.getInt("id"));
// adding movie to movies array
movieList.add(movie);
} catch (JSONException e) {
e.printStackTrace();
}
}
}catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
// notifying list adapter about data changes
// so that it renders the list view with updated data
adapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(movieReq);
}
#Override
public void onDestroy() {
super.onDestroy();
hidePDialog();
}
private void hidePDialog() {
if (pDialog != null) {
pDialog.dismiss();
pDialog = null;
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
It's the "id" that I want to get in the OnClick event.
use this code
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
Movie movie= movieList.get(position);
}
});
//here position will give you the id of listview cell so you can use it like
Movie movie= movieList.get(position);
then you can use it get all the data inside your moview object
I've use Filterable inside my RecyclerView. What I wanted to do is, to filter the recyclerview from edittext. Below is my actual code.
public class NavDrawerAdapter_v2 extends RecyclerView.Adapter<NavDrawerAdapter_v2.ViewHolder> implements Filterable{
private static final int TYPE_ITEM = 0;
private ArrayList<String> menu_list;
private ArrayList<String> filtered_menu_list;
Context mContext;
public static class ViewHolder extends RecyclerView.ViewHolder {
int Holderid;
TextView shopName, shopLevel;
public ViewHolder(View itemView,int ViewType) {
super(itemView);
shopName = (TextView) itemView.findViewById(R.id.rowText);
shopLevel = (TextView) itemView.findViewById(R.id.rowLevel);
if(ViewType == TYPE_ITEM) {
Holderid = 0;
}
}
}
public NavDrawerAdapter_v2(Context mContext, ArrayList<String> menu_list){
this.menu_list = menu_list;
this.filtered_menu_list = menu_list;
this.mContext = mContext;
}
#Override
public NavDrawerAdapter_v2.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == TYPE_ITEM) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.drawer_item_row,parent,false); //Inflating the layout
return new ViewHolder(v,viewType);
}
return null;
}
#Override
public void onBindViewHolder(NavDrawerAdapter_v2.ViewHolder holder, int position) {
if (holder.Holderid == 0) {
String getShopName = menu_list.get(position).split("-")[0];
String getShopLevel = menu_list.get(position).split("-")[1];
holder.shopName.setText(getShopName);
holder.shopLevel.setText(getShopLevel);
}
}
#Override
public int getItemCount() {
return menu_list == null ? 0 : menu_list.size();
}
#Override
public long getItemId(int position) {
return super.getItemId(position);
}
#Override
public int getItemViewType(int position) {
return TYPE_ITEM;
}
public boolean okay(){
return true;
}
#Override
public Filter getFilter() {
return new UserFilter(this, menu_list);
}
private static class UserFilter extends Filter {
private final NavDrawerAdapter_v2 adapter;
private final ArrayList<String> originalList;
private final ArrayList<String> filteredList;
private UserFilter(NavDrawerAdapter_v2 adapter, ArrayList<String>originalList) {
super();
this.adapter = adapter;
this.originalList = new ArrayList<>(originalList);
this.filteredList = new ArrayList<>();
}
#Override
protected FilterResults performFiltering(CharSequence constraint) {
filteredList.clear();
final FilterResults results = new FilterResults();
if (constraint.length() == 0) {
filteredList.addAll(originalList);
} else {
final String filterPattern = constraint.toString().toLowerCase().trim();
for (String getValue : originalList) {
if (getValue.contains(filterPattern)) {
filteredList.add(getValue);
}
}
}
results.values = filteredList;
results.count = filteredList.size();
return results;
}
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
adapter.filtered_menu_list.clear();
adapter.filtered_menu_list.addAll((ArrayList<String>) results.values);
adapter.notifyDataSetChanged();
}
}
}
But, in my fragment. I can't call adapter.getFilter(). What is wrong here?
If you want EditText for searchView purposes, you need to add change listener for EditText, as explained in the link : android on Text Change Listener
When the text changed, you should call
adapter.getFilter().filter(newText);
Alternatively, you should try to implement searchview in action bar with recyclerView. Todo this, implement getFilter() method inside your RecyclerView adapter. You can use the getFilter() method implemented in the link https://stackoverflow.com/a/10532898/1308990 .
menu.xml:
<item android:id="#+id/menuSearch"
android:title="search"
android:icon = "#android:drawable/ic_menu_search"
app:actionViewClass = "android.support.v7.widget.SearchView"
app:showAsAction = "always|collapseActionView"></item>
Inside onCreateOptionsMenu() method, write following codes :
MenuItem item = menu.findItem(R.id.menuSearch);
//SearchView searchView = (SearchView) item.getActionView();
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
//Called when the query text is changed by the user.
#Override
public boolean onQueryTextChange(String newText) {
Log.d("soda in MainActivity","onQueryTextChange method is called.");
mutfagimFragment.adapter.getFilter().filter(newText);
return false;
}
});
When the user changes the text, check whether the onQueryTextChange() method is called by monitoring the logs. If it is not called, try to put the above codes inside onPrepareOptionsMenu() method rather than onCreateOptionsMenu() method.
Following your example, I'm pretty sure you were assigning the object to a RecyclerView.Adapter variable instead of to a NavDrawerAdapter_v2 variable inside the Activity.
RecyclerView.Adapter adapter = new NavDrawerAdapter_v2(menuList);
instead of
NavDrawerAdapter_v2 adapter = new NavDrawerAdapter_v2(menuList);
NavDrawerAdapter_v2 extends from RecyclerView.Adapter but at the same time implements Filterable.
If you assign the object to a RecyclerView.Adapter variable you will still be able to call getItemCount(), onBindViewHolder() and onCreateViewHolder() (since they are abstract methods from RecyclerView.Adapter)
The bad part is that you won't be able to call getFilter() because it belongs to the Filterable interface.
How to make checkbox/combobox readonly in javaFX but not disabled.
I tried consuming onAction event but it didn't work.
checkBox.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
event.consume();
}
});
Consuming all events like in code below works but I don't think it's a good solution:
checkBox.addEventFilter(KeyEvent.ANY, new EventHandler<KeyEvent>() {
#Override
public void handle(KeyEvent event) {
event.consume();
}
});
checkBox.addEventFilter(MouseEvent.ANY, new EventHandler<MouseEvent>() {
#Override
public void handle(MouseEventevent) {
event.consume();
}
});
You can set the check box to disabled but set the the look of it using CSS. If you are using the default style you can make the check box look 'normal' by setting full opacity.
checkbox.setStyle("-fx-opacity: 1");
It is probably a similar deal with the combo box.
You can override method CheckBox#arm() with an empty one:
CheckBox cb = new CheckBox("hi") {
#Override
public void arm() {
// intentionally do nothing
}
};
If you do not want to overwrite the CheckBok class, you can use the selectedProperty.
CheckBox cb = new CheckBox("hi");
cb.selectedProperty().addListener(new NCL());
class NCL implements ChangeListener<Boolean> {
#Override
public void changed(ObservableValue<? extends Boolean> ov, Boolean old_val, Boolean new_val) {
cb.setSelected(false);
}
}
I have tryed to build a Java Class in JSf witch adds a view with a Pager to an XPage
Im Using a UiDataview in this simple example but my problem is that the Pager witch is added to the result is never displayed in my Xpage. anyone an idea what i have to do?
public class MainLibcontrol extends UIComponentBase implements FacesComponent {
private static final String RENDERER_TYPE = "de.my.MainLibcontrol";
private static final String COMPONENT_FAMILY = "de.my";
public MainLibcontrol() {
setRendererType(RENDERER_TYPE);
}
#Override
public String getFamily() {
return COMPONENT_FAMILY;
}
#SuppressWarnings("unchecked")
public void initBeforeContents(FacesContext arg0) throws FacesException {
try {
UIDataView viewtable = new UIDataView();
viewtable.setColumnTitles(true);
CategoryColumn categoryColumn = new CategoryColumn();
categoryColumn.setComponent(viewtable);
categoryColumn.setColumnName("form");
categoryColumn.setColumnTitle("form");
categoryColumn.setContentType("text");
viewtable.addCategoryColumn(categoryColumn);
DominoViewData data = new DominoViewData();
data.setComponent(viewtable);
data.setViewName("142342");
data.setVar("view2");
viewtable.setData(data);
viewtable.setId("dataView1");
viewtable.setRows(3);
SummaryColumn summaryColumn = new SummaryColumn();
summaryColumn.setComponent(viewtable);
summaryColumn.setColumnName("5");
summaryColumn.setColumnTitle("5");
viewtable.setSummaryColumn(summaryColumn);
XspPager pager = new XspPager();
pager.setPartialRefresh(true);
pager.setLayout("Previous Group Next");
pager.setId("pager1");
viewtable.getChildren().add(pager);
this.getChildren().add(viewtable);
} catch (Exception e) {
e.printStackTrace();
}
}
public void buildContents(FacesContext arg0, FacesComponentBuilder arg1) throws FacesException {
.....
}
public void initAfterContents(FacesContext arg0) throws FacesException {
....
}
}
I haven't tried this out, but I would imagine you want to add it as a facet of the viewTable not as a child.
so your line should be
viewtable.getFacets().put("headerPager", pager);
I'm trying to make my code neater by using multiple classes for my applications
form options. Currently I keep getting null pointer exceptions when trying to setCurrent.
Here is my main class the error starts in my command listener when I call the other class.
import java.util.*;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.MIDlet;
public class CalFrontEnd extends MIDlet implements CommandListener {
private Display display;
private List list = new List("Please Select a Option", List.IMPLICIT);
private List Blist = new List("Please Select a Browsing Option", List.IMPLICIT);
private Command select = new Command("Select", Command.SCREEN, 1);
private Command exit = new Command("Exit", Command.EXIT, 2);
private Command save = new Command("Save,", Command.SCREEN, 2);
private DateField calendar;
Alert alert;
//
//
//
public CalFrontEnd() {
display = Display.getDisplay(this);
list.append("Select Date", null);
list.append("Add Events", null);
list.append("Remove Events", null);
list.append("Browse Events", null);
list.addCommand(select);
list.addCommand(exit);
list.setCommandListener(this);
}
//
//Start Application Method
//
public void startApp() {
display.setCurrent(list);
}
//
//Pause Application Method
//
public void pauseApp() {
}
//
//Destroy Application Method
//
public void destroyApp(boolean unconditional) {
}
//
//Method creates form which contains calendar
//
/*public void selectDate()
{
calendar = new DateField("Date In :", DateField.DATE, TimeZone.getTimeZone("GMT"));
Form cform = new Form("Calendar");
cform.append(calendar);
cform.addCommand(exit);
display.setCurrent(cform);
}*/
//
//Method creates form which contains adding events
//
public void AddEvents()
{
TextBox aeText = new TextBox("Add Event","", 256, 0);
display.setCurrent(aeText);
}
//
//Method creates form which contains removing events
//
public void RemoveEvents()
{
Form reform = new Form("Remove Event");
reform.append(calendar);
display.setCurrent(reform);
}
//
//Method creates form which contains removing events
//
public void BrowseEvents()
{
Blist.append("Monthly", null);
Blist.append("Daily", null);
Blist.addCommand(select);
Blist.addCommand(exit);
Blist.setCommandListener(this);
display.setCurrent(Blist);
}
//
//but it's better practice to make each form a different class extending CommandListener and it's own commandAction. And leave the display public static in MIDlet class
//...
public void commandAction(Command command, Displayable displayable) {
if (displayable == list) {
if (command == List.SELECT_COMMAND) {
switch (list.getSelectedIndex()) {
case 0: // select date
SelectDate.BuildCalendar(); //Error Here
break;
case 1: //add events
AddEvents();
break;
}
} else if (command == exit) {
destroyApp(false);
notifyDestroyed();
}
}
}
}
And here is the class that is being called.
public class SelectDate
{
private static DateField calendar;
private static Form form = new Form("derb");
private static Command select = new Command("Select", Command.SCREEN, 1);
private static Command exit = new Command("Exit", Command.EXIT, 2);
private static Command save = new Command("Save,", Command.SCREEN, 2);
private static Display display;
public static void BuildCalendar()
{
calendar = new DateField("Date In :", DateField.DATE, TimeZone.getTimeZone("GMT"));
form.append(calendar);
form.addCommand(exit);
display.setCurrent(form);
}
}
The NullPointerException happens because display in SelectDate class is null.
To fix that, you can for example drop it from there and instead, add to method parameters:
// ...
public static void BuildCalendar(Display display) // added parameter
Then, when you invoke above method from CalFrontEnd, pass the instance of display there:
// ...
SelectDate.BuildCalendar(display); //Error will go away
