Why do I get this error when opening the drawer?

java.lang.Exception: Sub drawer_drawerslide signature does not match expected signature.

(this is in the demo)

I'll take a stab at this - this library makes use of Corwin42's excellent AHNavigationDrawer library and recently that library changed. Over in that thread Corwin42 writes in the 1.1 version release notes: "WARNING: Signature of the event subs have changed!", but I don't believe this library has yet been modified to play nicely with the new of AHNavigationDrawer that I'm guessing you have downloaded (as I did).

If you want to use the 1.1 version of AHNavigationDrawer library you need to make a couple of simple changes to this ActionDrawer class so that the drawer_drawerslide, drawer_drawerOpened and drawer_drawerClosed subs are accepting the correct number of parameters. Open up the actiondrawer sample project and the ActionDrawer class and scroll down to line 796. Change

B4X: 
Private Sub Drawer_DrawerSlide (Position As Float)
to
B4X: 
Private Sub Drawer_DrawerSlide (Position As Float, DrawerGravity as Int)

on line 826change

B4X: 
Private Sub Drawer_DrawerClosed

to

B4X: 
Private Sub Drawer_DrawerClosed (DrawerGravity as Int)

on line 845 change

B4X: 
Private Sub Drawer_DrawerOpened

to

B4X: 
Private Sub Drawer_DrawerOpened (DrawerGravity as Int)


If you want to double check AHNavigationDrawer.xml from the AHNavigationDrawer library you'll see that this is the correct parameters the equivalent subs require. I _think_ that is all the changes that need to be made, at the very least it clears up my errors.


I suspect either edgeryder1000 will be along shortly to update the Sample or more knowledgable B4A users will be along to correct me Hope that helps.

Hello, I have a problem with this class. If I create a second activity with a new action bar and I press a button on the action bar of the second activity, return to the first activity. Why?

Thanks!

I have the same problem. The sub is called in the Main activity whereas the actionbar is in another activity.

Well, I found a solution for this problem. The problem is that the class uses a lot of CallSubDelayed that calls to Main Activity.

The solution is declare in Process_Globals the variable "Dim ActivityName as String" and, in the "Activity_Create" of every activity, you have to give the value to the variable as the name of the activity. For example: Main.ActivityName = "Activity2"

Later you have to change all "callsubdelayed(Main,....)" in the class to "callsubdelayed(Main.ActivityName,...)"

Hi,
Can you help, please? The demo runs OK for me, but when I try to add the class to my own project, I get the following error at line 790 in your class:

Error occurred on line: 790 (actiondrawer)
java.lang.NoSuchFieldException: ic_overflow_white​

What I've noticed is that in your example, package is set to "actn.dwr" and in my code it's set to "b4a.example". Do I need to do something to install the required resources into my project?
Thanks
Andrew

Hi,
I think I've solved this myself. Changing the package name and cleaning the project seems to have sorted things out.

I manually copied the extra drawables files from the example to my project. is that the correct process?

Thanks for this great class.

When i load a layout into action drawer activity, this activity does not have the focus, so i cant acess the activity views.

SOLVED : with the correct android-support-v4.jar

@edgeryder1000
First of all my compliments! Outstanding work!
I'm using the Class within a multi activity app but I see that the Class link to Main in order to call events.

I'm planning to make some amendments in order to allow the class to link the "parent" activity events.
For example :

CallSub2(Main, "Overflow_Click", str.Trim) ---> We can pass the current* module name insted of "Main" ?

*For current module I mean the module that initialize the Class

N.B.
Actually if you call an event within an activity that is different from the "Main" you got an error "Sub myevent_Click not found..."

thanks for wonderful class wrapper.

is it possible to copy actionbar object in different activity.

like if i create actionbar with drawer in main activity. can i clone same action bar with drawer in other activity without adding views of drawer again.

Hello,

That's very much for this. I'm struggling a bit at the moment though, I fixed that I had forgotten to include the res folders but now I have this

B4X: 
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
An error occurred:
(Line: 147) AD.DrawerPanel.AddView(lInfo, 4dip, 0, AD.DrawerPanel.Width, 100dip)
java.lang.NullPointerException
(Intent) Intent { act=android.intent.action.MAIN flg=0x20000000 cmp=Something.B4AExample/.main }
no extras
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
An error occurred:
(Line: 255) NavDrawer.ShadowDrawable = GetDrawable("drawer_shadow")
java.lang.NullPointerException
(Intent) Intent { act=android.intent.action.MAIN flg=0x20000000 cmp=Something.B4AExample/.main }
no extras

Any ideas please? I thought it may be a conflict with my existing code but the demo just crashes out without logging anything.

Thank you

It doesn't seem to be much help. I've got an up to date Galaxy Note 3 as the handset which this is crashing on. If it's used at all I may however have issues with the Android SDK as I couldn't be sure it's up to date, installed in the correct location etc. My B4A is the latest.

I don't think I did anything to the demo beyond download and run it.

Thank you

How do I get my designer script to work with this? It works regularly with Activity.Loadlayout, but if I use ad.pcontent.loadlayout then my script doesn't work correctly?
