whats wrong? on other Place (other bal File) it works also on Android 4, i think its a Problem in the bal File or with the ScrollView??

 

[Erel]

whats wrong?

Panel size is unknown. Layout may not be loaded correctly

Add the ScrollView to the activity or parent panel and only then load the layout.

o.k., change, but error remains
(Panel size is unknown.... solved)

    Dim SV_FTP As ScrollView
    
    Dim CV As CustomLayoutDialog
    Dim sf As Object = CV.ShowAsync("FTP Zugang", _
                                    Starter.loc.Localize("txt_Save"), _
                                    Starter.loc.Localize("txt_Cancel"),"",Null, False)
        
    Wait For (sf) Dialog_Ready (DialogPanel As Panel)

    SV_FTP.Initialize(800dip)
    SV_FTP.Panel.Initialize("ftp_zugang_panel")

    DialogPanel.AddView(SV_FTP,0,0,100%x,100%y)

    SV_FTP.Panel.LoadLayout("ftp_zugang")

You will need to upload a small project that demonstrates it.

Why aren't you using B4XDialog? It has templates for lists.

If you are creating an input dialog then check B4XPreferencesDialog.

o.k., it will take a time. be note, the Error gets only on Android 4.4 Device (on my Android 9 Device all o.k.)
Edit -> TestFile add

Why aren't you using B4XDialog? It has templates for lists.

I have Create it long before B4X Dialogs start (and it works). Later i have change one Field to B4XFloatTextField, Test on newer Device, works.
Now i see it crash on older Device.

If you are creating an input dialog then check B4XPreferencesDialog.

i use it on other Place. For this its not the right.

"Update"
Test on Android 5.1, works
Test on other Android 4, Crash

Test on Android 4:
- Load a other Layout with B4XFloatTextField on CustomLayoutDialog (direct, no ScrollView), works
- Test with B4X Dialogs, crash (at load to ScrollView)
- Test with ScrollView2D, crash

-> it only Crash on Android 4 when load on ScrollView

Anyone an idea?

 

[Erel]

I still think that it will look much better if you use B4XPreferencesDialog.

You shouldn't initialize the ScrollView inner panel. Remove that line and try again.

remove Line, unfortunately the same error.

b4xfloattextfield_createbitmap (java line: 171)
java.lang.IllegalArgumentException: width and height must be > 0
.......

Line 168 to 171 from Java File:
//BA.debugLineNum = 233;BA.debugLine="Dim c As B4XCanvas";
_c = new anywheresoftware.b4a.objects.B4XCanvas();
//BA.debugLineNum = 234;BA.debugLine="c.Initialize(p)";
_c.Initialize(_p);

 

[Erel]

The crash happens because of a bug in XUI Views related to the empty hint text. It is fixed in v2.13.

solved, thank you!!
