change the background color of three textInputlayouts by using listener

I have three text input layouts in my activity, I apply a listener on them and it changes background color when I click on it .but need to click again if I want to click the other two .my question is that how I implement such type of logic that when it 1st clicked and I click on one of the other two, the first one clickable color disappear and 2nd one or third one clicked and its background color change and same for others
View.OnClickListener listener = new View.OnClickListener() {
#SuppressLint("NonConstantResourceId")
#Override
public void onClick(View v) {
if (v.getId() == R.id.textViewLoseWeightSubtitle) {
if (mStateChanged) {
v.setBackgroundResource(R.drawable.textview_after_click);
// mLoseWgt.setTextColor(Color.WHITE);
mStateChanged = false;
mFittedToned.setClickable(false);
mBuildMuscle.setClickable(false);
} else {
v.setBackgroundResource(R.drawable.textview_outline_style);
//mLoseWgt.setTextColor(Color.parseColor("#363C60"));
mStateChanged = true;
mFittedToned.setClickable(true);
mBuildMuscle.setClickable(true);
}
}
if (v.getId() == R.id.textViewBuildMusclesSubtitle) {
if (mStateChanged) {
v.setBackgroundResource(R.drawable.textview_after_click);
// mLoseWgt.setTextColor(Color.WHITE);
mStateChanged = false;
mLoseWgt.setClickable(false);
mFittedToned.setClickable(false);
} else {
v.setBackgroundResource(R.drawable.textview_outline_style);
//mLoseWgt.setTextColor(Color.parseColor("#363C60"));
mStateChanged = true;
mLoseWgt.setClickable(true);
mFittedToned.setClickable(true);
}
}
if (v.getId() == R.id.textViewFittedAndTonedSubtitle) {
if (mStateChanged) {
v.setBackgroundResource(R.drawable.textview_after_click);
// mLoseWgt.setTextColor(Color.WHITE);
mStateChanged = false;
mLoseWgt.setClickable(false);
mBuildMuscle.setClickable(false);
} else {
v.setBackgroundResource(R.drawable.textview_outline_style);
//mLoseWgt.setTextColor(Color.parseColor("#363C60"));
mStateChanged = true;
mLoseWgt.setClickable(true);
mBuildMuscle.setClickable(true);
}
}
}
};
mLoseWgt.setOnClickListener(listener);
mBuildMuscle.setOnClickListener(listener);
mFittedToned.setOnClickListener(listener);
}

What you need is a onFocusChangedListener(). It gives a callback with a boolean which can be used to identify whether the current view is selected or not.
Declare it as:
View.OnFocusChangeListener listener = new View.OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
v.setBackgroundResource(R.drawable.textview_after_click);
// mLoseWgt.setTextColor(Color.WHITE);
} else {
v.setBackgroundResource(R.drawable.textview_outline_style);
//mLoseWgt.setTextColor(Color.parseColor("#363C60"));
}
}
});
Set it as:
mLoseWgt.setOnFocusChangeListener(listener);
mBuildMuscle.setOnFocusChangeListener(listener);
mFittedToned.setOnFocusChangeListener(listener);
That's it. Your other code seems redundant. For EditText specific functions, you can typecast the view provided by onFocusChange().

JavaFX can not clear items from listview

I'm using a ListView in my project and wanted to add a context menu to each list item so that each can be removed individually. When using the following code this appears to work just fine:
postList.setCellFactory(lv -> {
ListCell<Result> cell = new ListCell<>();
ContextMenu contextMenu = new ContextMenu();
StringBinding stringBinding = new StringBinding() {
{
super.bind(cell.itemProperty().asString());
}
#Override
protected String computeValue() {
if (cell.itemProperty().getValue() == null) {
return "";
}
return cell.itemProperty().getValue().getTitle();
}
};
cell.textProperty().bind(stringBinding);
MenuItem deleteItem = new MenuItem();
deleteItem.textProperty().bind(Bindings.format("Delete item"));
deleteItem.setOnAction(event -> postList.getItems().remove(cell.getItem()));
contextMenu.getItems().addAll(openPermalink, openSubreddit, openURL, deleteItem);
cell.emptyProperty().addListener((obs, wasEmpty, isNowEmpty) -> {
if (isNowEmpty) {
cell.setContextMenu(null);
} else {
cell.setContextMenu(contextMenu);
}
});
return cell;
});
However, after clearing the post list - although the items appear to be removed - when another is added all of the removed items re-appear and the item to be added is not displayed.
Any items what could be causing this? It only happens when I set the cell factory and is fine otherwise.
I recorded a small gif to help better explain the issue:
Thank you!
Edit: It appears that the issue is mainly to do with this segment
StringBinding stringBinding = new StringBinding() {
{
super.bind(cell.itemProperty().asString());
}
#Override
protected String computeValue() {
if (cell.itemProperty().getValue() == null) {
return "";
}
return cell.itemProperty().getValue().getTitle();
}
};
As is seems that even though the items are there they have an empty display title

If you use ListCell.updateItem() workflow instead of the StringBinding it should work:
ListCell< Result > cell = new ListCell< Result >() {
#Override
protected void updateItem(String item, boolean empty) {
super.updateItem(item, empty);
if (item != null) {
setText(item.getValue());
} else {
setText("");
}
}
};
Your binding workflow seems to create an unnecessary dependency which blocks deletion.
P.S.: why do you use binding for static text in deleteItem? Just assign the value directly:
MenuItem deleteItem = new MenuItem();
deleteItem.setText("Delete item");

How to create Bottom Navigation

I am new to mobile development, I started using Gluon mobile for Netbeans and I'm trying to add a Bottom navigation bar to the default Gluon Mobile App. They describe the class in the JavaDoc http://docs.gluonhq.com/charm/javadoc/4.1.0/com/gluonhq/charm/glisten/control/BottomNavigation.html but I can't seem to make it work.
Would someone be able to post a snippet on how and where to do this?

Here is a simple example:
public class GluonApplication extends MobileApplication {
#Override
public void init() {
addViewFactory(HOME_VIEW, () ->
{
StackPane root = new StackPane();
root.getChildren().add(new Label("test"));
View view = new View(root) {
#Override
protected void updateAppBar(AppBar appBar) {
appBar.setTitleText("Home");
}
};
view.setBottom(createBottomNavigation());
return view;
});
}
private BottomNavigation createBottomNavigation() {
BottomNavigation bottomNavigation = new BottomNavigation();
ToggleButton btn1 = bottomNavigation.createButton("View1", MaterialDesignIcon.DASHBOARD.graphic(), e -> showView("view1"));
ToggleButton btn2 = bottomNavigation.createButton("View2", MaterialDesignIcon.AC_UNIT.graphic(), e -> showView("view2"));
ToggleButton btn3 = bottomNavigation.createButton("View3", MaterialDesignIcon.MAP.graphic(), e -> showView("view3"));
bottomNavigation.getActionItems().addAll(btn1, btn2, btn3);
return bottomNavigation;
}
private void showView(String viewName) {
MobileApplication.getInstance().switchView(viewName);
}
}

How to make an options menu for a PopupWindow?

My app has an options menu that is available in almost all Activities, which was created by implementing onCreateOptionsMenu(). But in one Activity there is a PopupWindow, and when this PopupWindow has focus (required for proper functioning) tapping the menu button does not bring up the options menu.
PopupWindows do not have an onCreateOptionsMenu() function. Is there some other way to add an options menu to a PopupWindow?
Alternatively, is there a way to get the options menu from the Activity behind it to show up when the user taps the menu button?

I solved this by intercepting the menu key and calling openOptionsMenu() on the activity. Here is the key listener:
OnKeyListener mMenuKeyListener = new OnKeyListener() {
#Override
public boolean onKey(View view, int keyCode, KeyEvent event) {
if(keyCode==KeyEvent.KEYCODE_MENU) {
activity.openOptionsMenu();
return true;
} else {
return false;
}
}
};
I think you have to add this key listener to every view in the PopupWindow to get it to work, so I wrote a function to do that:
public void setupMenuKeyListenerRecursive(View v) {
if (v != null) {
try {
ViewGroup viewGroup = (ViewGroup)v;
int childCount = viewGroup.getChildCount();
for (int index = 0; index < childCount; index++) {
View child = viewGroup.getChildAt(index);
setupMenuKeyListenerRecursive(child);
}
} catch (Exception e) {
}
v.setOnKeyListener(mMenuKeyListener);
}
}

How do I add a click handler to the GWT ButtonCell?

I created a ButtonCell and a Column for it:
ButtonCell previewButton = new ButtonCell();
Column<Auction,String> preview = new Column<Auction,String>(previewButton) {
public String getValue(Auction object) {
return "Preview";
}
};
How do I now add a click handler (e.g. ClickHandler) for this ButtonCell?

The Cell Sampler example includes use of clickable ButtonCells. Clicks on ButtonCells are handled by setting the FieldUpdater for the Column:
preview.setFieldUpdater(new FieldUpdater<Auction, String>() {
#Override
public void update(int index, Auction object, String value) {
// The user clicked on the button for the passed auction.
}
});

//Prevent mouse events for table cell
CellPreviewEvent.Handler<Auction > manager = DefaultSelectionEventManager.createBlacklistManager(4);//column number
cellTable.setSelectionModel(selectionModel, manager);
new Column<Auction , String>(new ButtonCell()){
#Override
public String getValue(Auction object) {
return "Preview";
}
#Override
public void onBrowserEvent(Cell.Context context, Element elem, Auction object, NativeEvent event) {
event.preventDefault();
//TODO implement event handling
}
}
