How can I set the safe area for pull to refresh? I have a form with with an infinite container. I set the IC with safe area ic.setSafeArea(true). When I rotate the screen the safe area is respected(see image 1). If i pull to refresh the safe area is not respected (see image 2). With the below code taken from the InfiniteContainerSample, how can I ensure the safe area is respected after pull to refresh?
image 1
public void showForm() {
Form hi = new Form("InfiniteContainer", new BorderLayout());
Style s = UIManager.getInstance().getComponentStyle("MultiLine1");
FontImage p = FontImage.createMaterial(FontImage.MATERIAL_PORTRAIT, s);
EncodedImage placeholder = EncodedImage.createFromImage(p.scaled(p.getWidth() * 3, p.getHeight() * 3), false);
InfiniteContainer ic = new InfiniteContainer() {
#Override
public Component[] fetchComponents(int index, int amount) {
java.util.List<Map<String, Object>> data = fetchPropertyData("Leeds");
MultiButton[] cmps = new MultiButton[data.size()];

I am trying to list all the PDF files from the external storage created by the app. How to list pdf files in the App after iterating through cursor?
private void getExternalPDFFiles() {
ContentResolver cr = getContentResolver();
Uri uri = MediaStore.Files.getContentUri("external");
// every column, although that is huge waste, you probably need
// BaseColumns.DATA (the path) only.
String[] projection = null;
// exclude media files, they would be here also.
String selection = MediaStore.Files.FileColumns.MEDIA_TYPE + "="
+ MediaStore.Files.FileColumns.MEDIA_TYPE;
String[] selectionArgs = null; // there is no ? in selection so null here
String sortOrder = null; // unordered
// Cursor allNonMediaFiles = cr.query(uri, projection, selection, selectionArgs, sortOrder);
// only pdf
String selectionMimeType = MediaStore.Files.FileColumns.MIME_TYPE + "=?";
String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("pdf");
String[] selectionArgsPdf = new String[]{mimeType};
Cursor cursor = cr.query(uri, projection, selectionMimeType, selectionArgsPdf, sortOrder);
assert cursor != null;
if (cursor.moveToFirst()) {
while (!cursor.isAfterLast()) {
//your code to implement
Log.d("TAG", cursor.getColumnNames().toString());
cursor.moveToNext();
}
}
Log.d("TAG", cursor.getCount() + "");

I have a problem: cannot get appointment body if it was created by outlook365 client.
When i run the code all properties values are being received except body.
After some searching i've found out that appointment bodies are not being received if appointments were made by outlook365.
Please, help!
The code:
public static List<Appointment> SetupConnection()
{
ServicePointManager.ServerCertificateValidationCallback = CallbackMethods.CertificateValidationCallBack;
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new WebCredentials("Someuser#somedomain.com", "SomePassword");
service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");
Folder calendarFolder = GetCalendarFolder(service, #"\");
return GetMeetings(calendarFolder, service);
}
public static List<Appointment> GetMeetings(Folder calendarFolder, ExchangeService service)
{
if (calendarFolder == null)
{
return null;
}
SearchFilter.SearchFilterCollection filters = new SearchFilter.SearchFilterCollection(LogicalOperator.And)
{
new SearchFilter.IsGreaterThan(AppointmentSchema.Start, DateTime.Today)
};
List<Appointment> meetings = new List<Appointment>();
const Int32 pageSize = 30;
ItemView itemView = new ItemView(pageSize);
PropertySet propertySet = new PropertySet(BasePropertySet.IdOnly);
itemView.PropertySet = propertySet;
FindItemsResults<Item> findResults = null;
do
{
findResults = calendarFolder.FindItems(filters, itemView);
itemView.Offset += pageSize;
meetings.AddRange(findResults.Cast<Appointment>());
} while (findResults.MoreAvailable);
PropertySet propertySet1 = new PropertySet(BasePropertySet.IdOnly);
propertySet1.Add(ItemSchema.Body);
propertySet1.Add(ItemSchema.Subject);
propertySet1.Add(AppointmentSchema.Organizer);
propertySet1.Add(AppointmentSchema.Start);
propertySet1.Add(AppointmentSchema.End);
propertySet1.Add(AppointmentSchema.Duration);
propertySet1.Add(AppointmentSchema.AppointmentType);
propertySet1.Add(AppointmentSchema.ConferenceType);
propertySet1.Add(AppointmentSchema.IsOnlineMeeting);
propertySet1.Add(AppointmentSchema.IsMeeting);
propertySet1.Add(AppointmentSchema.IsRecurring);
propertySet1.Add(AppointmentSchema.HasAttachments);
propertySet1.Add(AppointmentSchema.RequiredAttendees);
propertySet1.Add(AppointmentSchema.Resources);
propertySet1.Add(AppointmentSchema.InternetMessageHeaders);
propertySet1.RequestedBodyType = Microsoft.Exchange.WebServices.Data.BodyType.Text;
service.LoadPropertiesForItems(meetings, propertySet1);
return meetings;
}
}
Your code is only returning IdOnly
Try changing BasePropertySet.IdOnly to BasePropertySet.FirstClassProperties
I am implementing drop-drown feature in my app. Its implemented using container with list of elements in it.
Suppose the drop down list has following items aa1, aa2, aa3, aa4 aa5 and so on. And if i search as 'aa' it displays items starting from 'aa', if I select aa5 from list, it takes aa1 and displays that. But whereas if I scroll the items and select its working fine. This problem occurring only on iOS device working perfectly fine on simulator.
the first picture depicts how drop down looks like, in second picture if I search 'ee', it gives list of items starting with 'ee'. If I select 'ee5', it sets to ee1 as shown in picture 3. Problem only on device. Any workaround for this?
So, please let me know whats the issue with this.
Thanks

I would recommend using a Container and simple layout search as demonstrated by code such as this. The code below was taken from the Toolbar javadoc:
Image duke = null;
try {
duke = Image.createImage("/duke.png");
} catch(IOException err) {
Log.e(err);
}
int fiveMM = Display.getInstance().convertToPixels(5);
final Image finalDuke = duke.scaledWidth(fiveMM);
Toolbar.setGlobalToolbar(true);
Form hi = new Form("Search", BoxLayout.y());
hi.add(new InfiniteProgress());
Display.getInstance().scheduleBackgroundTask(()-> {
// this will take a while...
Contact[] cnts = Display.getInstance().getAllContacts(true, true, true, true, false, false);
Display.getInstance().callSerially(() -> {
hi.removeAll();
for(Contact c : cnts) {
MultiButton m = new MultiButton();
m.setTextLine1(c.getDisplayName());
m.setTextLine2(c.getPrimaryPhoneNumber());
Image pic = c.getPhoto();
if(pic != null) {
m.setIcon(fill(pic, finalDuke.getWidth(), finalDuke.getHeight()));
} else {
m.setIcon(finalDuke);
}
hi.add(m);
}
hi.revalidate();
});
});
hi.getToolbar().addSearchCommand(e -> {
String text = (String)e.getSource();
if(text == null || text.length() == 0) {
// clear search
for(Component cmp : hi.getContentPane()) {
cmp.setHidden(false);
cmp.setVisible(true);
}
hi.getContentPane().animateLayout(150);
} else {
text = text.toLowerCase();
for(Component cmp : hi.getContentPane()) {
MultiButton mb = (MultiButton)cmp;
String line1 = mb.getTextLine1();
String line2 = mb.getTextLine2();
boolean show = line1 != null && line1.toLowerCase().indexOf(text) > -1 ||
line2 != null && line2.toLowerCase().indexOf(text) > -1;
mb.setHidden(!show);
mb.setVisible(show);
}
hi.getContentPane().animateLayout(150);

I try to create a PDF report from a datatable. One of the columns contents image. How can I extract the image from datatable and insert into PDF table? I'm using iTextShap version 5.4.2.0. Here is the code:
public void Report(DataTable dt, string output)
{
Document doc = new Document(PageSize.LETTER, 50, 50, 80, 50);
PdfWriter PDFWriter = PdfWriter.GetInstance(doc, new FileStream(output, FileMode.Create));
PDFWriter.ViewerPreferences = PdfWriter.PageModeUseOutlines;
iTextSharp.text.Font hel8 = FontFactory.GetFont(BaseFont.HELVETICA, 8);
doc.Open();
PdfPTable table = new PdfPTable(dt.Columns.Count);
float[] widths = new float[] { 1.2f, 1.2f, 1.2f, 1.2f, 1f, 4f, 1f, 4f };
table.SetWidths(widths);
table.WidthPercentage = 100;
PdfPCell cell = new PdfPCell(new Phrase("NewCells"));
cell.Colspan = dt.Columns.Count;
foreach (DataColumn c in dt.Columns)
{
table.AddCell(new Phrase(c.ColumnName, hel8));
}
foreach (DataRow r in dt.Rows)
{
if (dt.Rows.Count > 0)
{
table.AddCell(new Phrase(r[0].ToString(), hel8));
table.AddCell(new Phrase(r[1].ToString(), hel8));
table.AddCell(new Phrase(r[2].ToString(), hel8));
table.AddCell(new Phrase(r[3].ToString(), hel8));
table.AddCell(new Phrase(r[4].ToString(), hel8));
table.AddCell(new Phrase(r[5].ToString(), hel8));
byte[] byt = (byte[])r[6];
MemoryStream ms = new MemoryStream(byt);
System.Drwaing.Image sdi = System.Drawing.Image.FromStream(ms);
Image img = Image.GetInstance(sdi); <-- this is the problem code
table.AddCell(img);
table.AddCell(new Phrase(r[7].ToString(), hel8));
}
}
doc.Add(table);
}
doc.Close();
}
Update: #nekno, all of your suggestions are worked.
But I still need to correct the casting at line:
byte[] byt = (byte[])r[6];
It gave me a casting exception from VS2008. So I added the conversion function (pulled it from stackoverflow):
byte[] ImageToByte(System.Drawing.Image img)
{
byte[] byteArray = new byte[0];
using (MemoryStream stream = new MemoryStream())
{
img.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
stream.Close();
byteArray = stream.ToArray();
}
return byteArray;
}
And revised the code:
byte[] byt = ImageToByte((System.Drawing.Image)dt.Rows[e][6]);
Thanks.
What exactly is the problem? What happens when you use your problem code?
Try one of the other Image.GetInstance() overloads:
You can pass the byte array directly:
byte[] byt = (byte[])r[6];
Image img = Image.GetInstance(byt);
Or you can pass the Stream:
byte[] byt = (byte[])r[6];
MemoryStream ms = new MemoryStream(byt);
Image img = Image.GetInstance(ms);
Or you can give iTextSharp more info about the image format:
byte[] byt = (byte[])r[6];
MemoryStream ms = new MemoryStream(byt);
System.Drawing.Image sdi = System.Drawing.Image.FromStream(ms);
Image img = Image.GetInstance(sdi, ImageFormat.Png);
If your column can be cast to a System.Drawing.Image, then you can use it directly:
Image img = Image.GetInstance((System.Drawing.Image)r[6], System.Drawing.Imaging.ImageFormat.Png);
I have suggested steps how shows how to add image into PDF, given below code snippet show how to add logo into your PDF using iTextsharp, follow provided below steps:
I have provided link to download "itextsharp" component from given link http://sourceforge.net/projects/itextsharp/
You have to add reference into your application.
Next you have to add required namespaces "iTextsharp.text.html", "iTextsharp.text" to consume its best properties.
Now you have to add code snippet into your application given at the end, add code snippet under "button click" in code behind.
Hope it will work for you !!!

How can i auto slide the imageViewer for instance in the interval of 3 seconds.
Or is there any other component that can do the auto swipe task.
ImageViewer imv = new ImageViewer();
DefaultListModel<Image> images = new DefaultListModel<Image>(new Image[]{a, thumbnail1, thumbnail2});
imv.setImage(images.getItemAt(0));
imv.setImageList(images);
imv.setSwipePlaceholder(Image.createImage(100, 100));
Declare this global static variable:
private static int slideIndex = 0;
//And this UITimer
UITimer t;
And then try out below code
final ImageViewer imv = new ImageViewer();
final DefaultListModel<Image> images = new DefaultListModel<Image>(new Image[]{a, thumbnail1, thumbnail2});
imv.setImage(images.getItemAt(0));
imv.setImageList(images);
imv.setSwipePlaceholder(Image.createImage(100, 100));
Runnable r = new Runnable() {
public void run() {
if (slideIndex < images.getSize()) {
slideIndex++;
} else {
slideIndex = 0;
}
Image nextImage = (Image) images.getItemAt(slideIndex);
if (nextImage != null) {
imv.setImage(nextImage);
}
}
};
if (t == null) {
t = new UITimer(r);
}
if (t != null) {
t.schedule(3000, true, f); //3 seconds
}
