B4i Library iHUD library - Toast messages and progress dialogs

This library is based on the following open source project: https://github.com/matej/MBProgressHUD
License: https://github.com/matej/MBProgressHUD/blob/master/LICENSE

It includes two features available in B4A: Toast messages and progress dialogs.

Using this library is very simple.
Declare a process global variable:

Private hd As HUD

Show a toast message:

hd.ToastMessageShow("Some message", True) 'second parameter is LongDuration

Unlike in Android the toast message appears in the middle of the screen.

Show a progress dialog (that disables user interaction):

hd.ProgressDialogShow("Downloading...")

Later you should call hd.ProgressDialogHide. Note that there is no DoEvents method in B4i. You should instead use asynchronous method for long tasks (when such are available).

Library installation:
- Download the zip file, unzip it and copy the xml file to the libraries folder.

where is hud.jar in rar/zip ???

I think for you need only the xml (remote compilation)

 

[Mikonios]

Remote Compilation is for small proyect and only trial versión.
Is posible hud.jar file ????

 

[Erel]

You are confusing B4A remote compilation with B4i remote compiler. This is B4i forum.

 

[Mikonios]

Excuse. It's true. Sorry

Could a couple enhancements be made to the iHUD library? It cuts off the text if there is a bunch of text. It also doesn't let you use CRLF to break up the text onto multiple lines. Thanks.

Hi Erel

thanks for this excellent library. I am however having issues with the async method, as you say with B4A its simply a question of adding in 'DoEvents', but I was wondering if you could clarify how to create a async method?

For example:-

<code>
Dim hd As HUD
hd.ProgressDialogShow("busy")
DoBusyEvent
hd.ProgressDialogHide

Private Sub DoBusyEvent

For i=0 To 10000
Log(i)
Next
End Sub
</code>

how could I make 'DoBusyEvent' an async method, i.e. so that the busy message is shown whilst the method is running, and only closed once it is finished?
Many thanks!

 

[Erel]

Please start a new thread for this question and also explain what is happening in the DoBusyEvent sub.

I already copied the iHUD.xml but the compiler replies that the iHUD.jar file is missing. Where can I get it?

Never mind. it did complile, the message appeared upon loading the project but it did complie anyway.

Hi,

I have a long message to show using Toastmessage. in Android it shows fine, but using this library in iOS the message is truncated. How can I show a long message as a toastmessage ?

 

[Erel]

You will not be able to do it with a toast message.

 

[cooperlegend]

OK, that's a shame, as I was hoping it would match the Android version, I guess I will switch to a msgbox instead. Thanks

 

[Paul Leischow]

Any way to have the ability to set the position of the message?
I would prefer to the the message at the bottom of the screen like the Android Toast Message instead of the middle of the screen.

 

[Erel]

You can use this sub to change the offset of the toast message:

Sub SetHUDOffset(offset As Float)
   Dim no1 As NativeObject = App.KeyController
   no1 = no1.GetField("view")
   Dim no2 As NativeObject
   Dim hud As NativeObject = no2.Initialize("MMBProgressHUD").RunMethod("HUDForView:", Array(no1))
   If hud.IsInitialized Then
     hud.SetField("yOffset", offset)
   End If
End Sub

For example:

hd.ToastMessageShow("test", True)
SetHUDOffset(Page1.RootPanel.Height / 2 - 100) 'note that RootPanel height will be 0 in Application_Start

wonderful.
I came across this thread just as I was tearing out the remaining few strands of hair on my head trying to get activityView to operate consistently.
Thank You!

Can we change font and background color?
