Share My Creation WorldClock widget

corwin42 · Feb 22, 2013

This is a very simple WorldClock widget.

I wanted to find out what is possible with B4A and widgets and so I started to create this project.

I think the result is quite amazing. At the beginning of this project I haven't thought that this all is possible but thanks to the great Reflection library I got all working as expected.

Be aware that it is only a widget and not a complete app, so just add it to your homescreen and configure it. To change the settings for a widget click on it.

The widget has the following features:
- Resizable layout (works with most custom launcher and stock launcher since Android 3+)
- Different instances of the same widget. All with their own settings.
- Search for any location in the world and set its timezone automatically. This uses the standard Android search feature, geolocation and a web service.
- Widget configuration screen.
- Different layouts for portrait and landscape
- Selectable layout from widget configuration screen
- Adjustable widget transparency (Android 2.1 and up)
- Correct widget size for Android 4+
- Uses different background on different Android Versions
- Detects changes in system settings (Manually setting time and timezone)
- Uses correct Time and Date format according to Device settings
- NEW: Real time preview of the exact widget

The project uses the following libraries:
- AHLocale - For TimeZone selection and formatting dates and times.
- AHViewPager - For selecting different widget layouts.
- Geocoder - For searching for locations
- HTTP - For requesting timezone data
- ICOSImageView - For displaying the widget layout preview images (Needs special scale type)
- IME - For closing the keyboard after searching for location
- Phone - Detecting Android version
- Reflection - For many magic things.
- XmlSax - For parsing Webservice result (Timezone)
- HTTPUtils2 - For requesting TimeZone data from webservice
- Statemanager - For saving widget settings and saving Activity state
- Dialogs - For the color dialog (setting text color)

V1.1:
- Show the real widget in the preview
- Added colordialog for selecting text color

My android device can't handle working widgets examples at all, so I would like to try yours one.
At compiling there is an error:
Sub GeoCoder_GeocodeDone(Address1() As Address, Tag As Object) -> Error description: Unknown type: address
Can you help me, what is missing from the zip file posted at first post?
thanks in advance

Hi.

do you remember how did you fix that issue? i am trying to run the project but i always get the same error !!!
Sub GeoCoder_GeocodeDone(Address1() As Address, Tag As Object) Error description: Unknown type: address

B4X:

Sub GeoCoder_GeocodeDone(Address1() As Address, Tag As Object)
    Dim loca As myLocation

    'Sometimes the geocoder does not return a result (timeouts?). In this case we try to geocode the search string up to 5 times.
    If Address1.Length = 0 And Tag < 5 Then
        Dim geo As Geocoder
        geo.Initialize("GeoCoder")
        geo.GetFromLocationName(gSearchString, 5, (Tag + 1))
        Return
    End If

    'Get some information from the resulting location.
    If Address1.Length > 0 Then
        For i = 0 To Address1.Length - 1
            If Address1(i).HasLatitude And Address1(i).HasLongitude Then
                Dim loca As myLocation
                loca.Initialize
                
                loca.Latitude = Address1(i).Latitude
                loca.Longitude = Address1(i).Longitude
                If Address1(i).Locality <> Null Then
                    loca.Name = Address1(i).Locality
                Else
                    If Address1(i).FeatureName <> Null Then
                        loca.Name = Address1(i).FeatureName
                    Else
                        If Address1(i).AddressLines <> Null And Address1(i).AddressLines.Size > 0 Then
                            loca.Name = Address1(i).AddressLines.Get(0)
                        End If
                    End If
                End If
                            
                If Address1(i).CountryName <> Null Then
                    loca.Name = loca.Name & " (" & Address1(i).CountryName & ")"
                End If
                Exit
            End If
        Next
    End If
    
    'If a location is found then Request timezone data from this location
    If loca.IsInitialized Then
        RequestTimeZone(loca)
    Else
        ProgressDialogHide
        ToastMessageShow("Unable to find location!", True)
    End If
End Sub

Yes, I remember. I needed to search geocoder library in the forum!
