I'm trying to prevent a CollapsingToolbar from expanding for one of my fragments.
Currently, when I use the method setExpanded(), I am able to see the toolbar in its collapsed state.
appBarLayout.setExpanded(false, true);
However, the collapsingToolbar is still expandable, which is not what I want. I want the collapsingToolbar to not be expandable for this particular fragment.
In other words, I want the collapsingToolbar to behave and look like a regular toolbar (i.e. "not expandable") for this particular fragment only.
I am using Mike Penz's Material Drawer. The code below shows the relevant code, with notes indicating what I have tried.
private void buildDrawer(){
Drawer drawer = new DrawerBuilder()
.withActivity(this)
.withFullscreen(true)
.withTranslucentStatusBar(true)
.withToolbar(toolbar)
.withAccountHeader(accountHeader)
.addDrawerItems(
item1,
item2,
new DividerDrawerItem(),
item3,
item4
)
.withOnDrawerItemClickListener(new Drawer.OnDrawerItemClickListener() {
#Override
public boolean onItemClick(View view, int position, IDrawerItem drawerItem) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
Fragment f = new Fragment();
switch (position) {
//other cases not shown
case 2:
f = new LocateFragment();
appBarLayout.setExpanded(false, true);
//Adding the following three lines don't work - causes the toolbar to be unscrollable, but in its expanded form
//AppBarLayout.LayoutParams p = (AppBarLayout.LayoutParams)collapsingToolbarLayout.getLayoutParams();
//p.setScrollFlags(AppBarLayout.LayoutParams.SCROLL_FLAG_SNAP);
//collapsingToolbarLayout.setLayoutParams(p);
//toolbar.setCollapsible(false); doesn't work either
collapsingToolbarLayout.setTitle("Locate Events");
setInvisibleAddPhotoFab();
break;
//other cases not shown
}
fragmentTransaction.replace(R.id.frame_fragments, f);
fragmentTransaction.commit();
return false; //close drawer onclick
}
})
.build();
loadBackdrop();
}
This is what I want - I want the toolbar to be unexpandable:
Currently, however, it is still expandable, so the image below is NOT what I want:
UPDATE:
I was able to collapse the toolbar and prevent it from expanding like so (code below), but I've run into another issue - the title no longer appears on the collapsingToolbar when I set it like so: collapsingToolbarLayout.setTitle("string");
appBarLayout.setExpanded(false, true);
int px = (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 80, getResources().getDisplayMetrics());
CoordinatorLayout.LayoutParams lp = (CoordinatorLayout.LayoutParams)appBarLayout.getLayoutParams();
lp.height = px;
appBarLayout.setLayoutParams(lp);
I was able to resolve this problem using the following (as shown here by #DanielPersson):
collapsingToolbarLayout.setTitleEnabled(false);
toolbar.setTitle(title);

I'm using barteksc pdf viewer library to load pdf in my application.
pdfView = findViewById(R.id.pdfView);
pdfView.fromAsset(getResources().getString(R.string.pdfname))
.enableDoubletap(true)
.enableSwipe(true)
.defaultPage(pageNumber)
.onPageChange(mainreading.this)
.pageFitPolicy(FitPolicy.WIDTH)
.pageFling(true)
.linkHandler(null)
.enableAnnotationRendering(true)
.swipeHorizontal(true)
.scrollHandle(new DefaultScrollHandlenew(mainreading.this))
.enableAntialiasing(true)
.load();
}
I want pdf to start scroll automatically when user click the button of volume up and down buttons to start stop. I tried with below code while wrapping it in the handler with handler.performClick(); but it shows blank screen while scrolling up and down.
scrollbutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pdfView.scrollTo(0, pdfView.getScrollY() + 24);
}
});
Example :
https://play.google.com/store/apps/details?id=com.emptysheet.pdfreader_autoscroll&hl=en&gl=US
I want to make as like this. Can anyone help please.
Also tried with this. But it shows blank page after some scrolls.
#Override
public boolean dispatchKeyEvent(KeyEvent event) {
int action = event.getAction();
int keyCode = event.getKeyCode();
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_UP:
if (action == KeyEvent.ACTION_DOWN) {
pdfView.scrollTo(0, pdfView.getScrollY() -24);
}
return true;
case KeyEvent.KEYCODE_VOLUME_DOWN:
if (action == KeyEvent.ACTION_DOWN) {
pdfView.scrollTo(0, pdfView.getScrollY() + 24);
}
return true;
default:
return super.dispatchKeyEvent(event);
}
}
You can simply use this PDF viewer from github.
It's based on the same 'barsteksc' pdf viewer with the feature to jump to any pages.
It's MagicalPdfViewer and you can use 'jumpTo(pageNo)' method to simply jump to the specific page. It also gives you the option to animate to the specific page with the same method, just pass 'true' as the 2nd parameter.
Moreover, if you pass the values like '-1' and 'bigger than pageNo', It will automatically scroll to the 0 & last page respectively.
Give it a try & let me know if you got what you wanted.
I want to do something like that:
So at the left side atm I have in the rootController a ListView
#FXML
ListView<String> listView;
which has two Elements, to stick to the picture let's call them ListElement A and B.
First I added these Elements
ObservableList<String> names = FXCollections.observableArrayList("A", "B");
Second I add them to the List:
listView.setItems(names);
in the start method i call the initRootLayout method
void initRootLayout() {
FXMLLoader fxmlLoader = new FXMLLoader(MainDo.class.getResource("view/RootLayout.fxml"));
try {
rootLayout = fxmlLoader.load(); // rootLayout == BorderPane
Scene scene = new Scene(rootLayout);
RootController rootController = fxmlLoader.getController();
primaryStage.setScene(scene);
primaryStage.show();
} catch (IOException e) {
e.printStackTrace();
}
}
My Problems:
If I start my application it loads the everything fine, except the fact that the content of the list is not shown. It looks like that:
If i fix that Problem, I am looking for the feature that A and B have a different fix Tab Pane. So if I am clicking on A and B was shown before, another Tab Pane is shown where i can show different content. So if i have n Elements in the List, I also have n Tab panes.
Can someone please help me here? I tried that already the last 8 hours with zero success.
Thanks
I want to implement a PieChart with a SelectionWidget. Upon clicking on a segment within an AndroidPlot PieChart, I would like the selection widget label text to display info about the current selected segment. There is an example to do this for an XYPlot within the AndroidPlot demo but it does not translate over well to the PieChart. Any help would be appreciated. Thank you.
I just posted a solution to a similar question here. It was necessary to add a new method to the PieRenderer class but there's a link to a build of Androidplot containing the necessary changes. It's not a production build but for whatever it's worth, its at least as stable as the current production version of Androidplot. Once you have the new build, you'll be able to do something like this:
// detect segment clicks:
pie.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
PointF click = new PointF(motionEvent.getX(), motionEvent.getY());
if(pie.getPieWidget().containsPoint(click)) {
Segment segment = pie.getRenderer(PieRenderer.class).getContainingSegment(click);
if(segment != null) {
// handle the segment click...for now, just print
// the clicked segment's title to the console:
System.out.println("Clicked Segment: " + segment.getTitle());
}
}
return false;
}
});
Just replace System.out.println(...) with your code to update the SelectionWidget.
I have a jTabbedPane with multiple tabs in it. I am trying to make the title text of the selected/active tab bold. Is there a simple way to do this?
JTabbedPane pane = new JTabbedPane();
pane.addChangeListener(new ChangeListener(){
#Override
public void stateChanged(ChangeEvent e) {
JTabbedPane source = (JTabbedPane) e.getSource();
// Set all tabs to PLAIN font
for(int i = 0; i < source.getTabCount(); i++) {
Component c = source.getTabComponentAt(i);
c.setFont(c.getFont().deriveFont(Font.PLAIN));
}
Component selectedComp = source.getTabComponentAt(source.getSelectedIndex());
// Set selected component to BOLD
selectedComp.setFont(selectedComp.getFont().deriveFont(Font.BOLD));
}
});
Try this, i wrote it quickly, maybe you need to do some adjustments for the initial tab, don't know for sure.
Also not so sure if you need JTabbedPane.getTabComponentAt(int idx) or JTabbedPane.getComponentAt(int idx) although i suppose first version is correct.
I know that this question was asked a long time ago, but I recently wanted to do this as well. I found the answer here. The solution was one of two things:
Use tabbedPane.setTitleAt(currSelextedIdx, "<html><b>My tab title</b></html>");
Create your own UI implementation for the tabbed pane
I personally used the first option and set all the other tabs back to the regular tab title on a change. I also made the initial tab bold after initializing all the tabs (this can be done upon initialization).
The simplest solution I've found until now. In a subclass of JTabbedPane, override two methods as below. When the tab is added, the raw title is persisted as a client property of the tab component. When the selected tab changes, the current tab title is restored to the raw title and the next tab title is set to bold with HTML.
public class MyTabbedPane extends JTabbedPane {
...
#Override
public void insertTab(String title, Icon icon, Component component, String tip, int index) {
((JComponent)component).putClientProperty("title", title);
super.insertTab(title, icon, component, tip, index);
}
#Override
public void setSelectedIndex(int index) {
int currentIndex = getSelectedIndex();
if (currentIndex >= 0) {
JComponent previous = (JComponent) getComponentAt(currentIndex);
String title = (String) previous.getClientProperty("title");
setTitleAt(currentIndex, title);
}
super.setSelectedIndex(index);
JComponent current = getSelectedComponent();
String title = (String) current.getClientProperty("title");
setTitleAt(index, "<html><b>" + title + "</b></html>");
}
}
I have 2 Telerik's rad grids. First one is master and second one is detail. I can delete rows from both grids independently by pressing "Delete" button on toolbar above each grid. I also have "Refresh" buttons in toolbar of both grids.
The problem is with detail grid. When I delete item(s) the grid doesn't refresh. Calling Rebind method doesn't help. The only thing that helps is to press "Refresh" button in toolbar of master grid and select the row in master grid by mouse that was previously selected. After that I can see refreshed detail grid.
So, I don't need to press "Refresh" button in toolbar of master grid and select the row in master grid by mouse. I can refresh the master grid programmatically and only want to reselect the item that was originally selected also programmatically. I've tried this:
item.Selected = true;
But, it only visually selects the item in master grid and doesn't refresh the detail grid.
So, how to select the item in master grid programmatically in order to get the same effect as selecting it by mouse?
Thank you in advance.
I've just realised that your probably using different DataSource for both grids, but pointing to the same database, right? My example below uses the same datasource for both grids. However I made on a detail view versus a normal view by making some columns not visible. Maybe this strategy could fix your issue?
My first thought was to try implement the SelectionChanged event, or if not that, the SelectionChanging event. Put a refresh in there you see. But I didn't end up doing it that way.
I wrote a small program as below. It saves the edits to disk with any row change as long as its not a remove (I had trouble saving remove edits when the button was clicked it gave a null pointer exception on the remove command). It also saves changes just before closing the program (so that any delete rows are also saved then). I did find that the deleteOne and deleteTwo buttons (that delete from the first or second grid, respectively) do in fact cause the deletion to occur in both grids. So a possibility is you could use the radGridView1.Rows.Remove(row) or RemoveAt(i) command if that works in your situation?
Another possibility is that if refresh isn't working you could set the DataSource to null and then set it to the data source again, after deleting the row. This is a bit drastic but if it's the only thing that works? I'm talking about the data source for both grids.
