BitsAndBytes · Jun 28, 2017

I have one app with 2 activities one Main and one with the option to change language. When my app stats i create a menu but i want when the user change language so do menu to change language each time the activity is resuming ..

B4X:

#IgnoreWarnings: 11
Sub Activity_CreateMenu(menu As ACMenu)
   menu.Clear
   menu.Add(1,0,Module.MenuTranslate(0),Null)
   menu.Add(2,0,Module.MenuTranslate(1),Null)
End Sub

Sub RefreshMenu()
   acactionbar.Menu.Clear
   acactionbar.menu.Add(1,0,Module.MenuTranslate(0),Null)
   acactionbar.menu.Add(2,0,Module.MenuTranslate(1),Null)
End Sub

But each time my app try to refresh my menu and load the new translation i receive that error...

See this example: https://www.b4x.com/android/forum/threads/appcompat-with-toolbar-minimal-example.79896/#post-509530

You can call GetMenuItem to get an existing item and then modify it.

I found the problem here ...

B4X:

   dim strMenuItemTitle as string = "Menu Title 1"
    Menu.Add(0, 0, strMenuItemTitle , Null)

When i put the strMenuItemTitle my app crashes but when i use the code below everything works fine ..

B4X:

    Menu.Add(0, 0, "Menu Title 1", Null)

How i can convert String To Charsequence? Thank you

Use the CSBuilder

BitsAndBytes · Jun 29, 2017

B4X:

  Dim charSequences As CSBuilder
  charSequences.Initialize
  menu.Clear
  menu.Add(1, 0, charSequences.Append(Module.arrCategoriesPanel(0)), Null)

The Module.arrCategoriesPanel(0)) just has a string value like "Menu Option 1" but this Does not work

Misterbates · Jun 29, 2017

Could you post the error? Don't forget to post it inside a code or quote block ...
And could you post your current code (including sub/end sub surrounds) - getting one or two lines may not be enough to see the bigger picture

BitsAndBytes · Jun 29, 2017

B4X:

#IgnoreWarnings: 11
Sub Activity_CreateMenu(menu As ACMenu)  
   Dim dummy As CSBuilder
   dummy.Initialize

   Dim cs() As CSBuilder = Array As CSBuilder(dummy)
   cs(0).Initialize.Append(Module.arrCategoriesPanel(0))  

   menu.Clear  
   menu.Add(1, 0, cs(0), Null)
End Sub

The problem is that i need to convert Module.arrCategoriesPanel(0) which is a string with value "Menu Option 1" , to charSequence

DonManfred · Jun 29, 2017

You DONT need multiple CSBuilders. See CSBuilder Tutorial.

Declare one GLOBAL and use the same every time...

Something like

B4X:

 Dim cs As CSBuilder ' Global var....
menu.add(cs.Initialize.Append(Module.arrCategoriesPanel(0)).PopAll, null)

BitsAndBytes · Jun 29, 2017

The same error again with this code

B4X:

#IgnoreWarnings: 11
Sub Activity_CreateMenu(menu As ACMenu)
      dim strText as String
      strText = "I am a simple text message, please work!!!"
      menu.Clear
      menu.add(1, 0, cs.Initialize.Append(strText).PopAll, Null)
End sub

Thats the error again ...

** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **

if i use this code below every think works fine, what is going on

B4X:

#IgnoreWarnings: 11
Sub Activity_CreateMenu(menuAs ACMenu)
     menu.Clearmenu.add(1, 0, ""I am a simple text message, please work!!!", Null)
End sub

my manifest is <uses-sdk android:minSdkVersion="14" android:targetSdkVersion="19"/>

i am using this C:\android-sdk-windows\platforms\android-26\android.jar

on an android device with 4.2.2 API 17

Misterbates · Jun 29, 2017

Try the following:
1) Clean your project (Ctrl+P)
2) Export your project as zip (file menu)
3) Delete (or rename) your project folder
4) Unzip from the export to a folder with the same name as you were using
5) Open and compile.

I've found that sometimes errors like this are fixed by using a "clean" environment.

Misterbates · Jun 29, 2017

Another idea...

In my (working) implementation I have the following to create the initial menu:

B4X:

#If Java

public boolean _onCreateOptionsMenu(android.view.Menu menu) {
    if (processBA.subExists("activity_createmenu")) {
        processBA.raiseEvent2(null, true, "activity_createmenu", false, new de.amberhome.objects.appcompat.ACMenuWrapper(menu));
        return true;
    }
    else
        return false;
}
#End If

#IgnoreWarnings: 11
Sub Activity_CreateMenu(Menu As ACMenu)
    Menu.Clear
    Dim item As ACMenuItem
    ' Add Create folder item - number < 100 so it's never removed.
    Menu.Add2(10, 1, moResStrings.Get(sRES_TOOLBAR_CREATEFOLDER), modUtility.GetDrawable("ic_folder_add_black_24dp", moIcons)).ShowAsAction = item.SHOW_AS_ACTION_ALWAYS
    ' Add other menu items (under a More button)
    UpdateMenu(Menu, True)
End Sub

I have the following to update the menu (called from Activity_Resume and a few other places in my code)

B4X:

private Sub UpdateDisplay
    Dim oMenuItem As ACMenuItem
    ' Clear existing dynamic items (if any)
    If barAction.Menu.Size > 0 Then
        oMenuItem = barAction.Menu.GetItem(barAction.Menu.Size - 1)
        Do While oMenuItem.Id >= 100
            barAction.Menu.RemoveItem(oMenuItem.Id)
            oMenuItem = barAction.Menu.GetItem(barAction.Menu.Size - 1)
        Loop
    End If
    ' Setup toolbar and menu items depending on whether we're showing root folder or a sub folder
    If goStorage.sCurrentFolder = goStorage.sRootFolder Then
        barHelper.ShowUpIndicator = False
        barAction.Title = Application.LabelName
        barAction.SubTitle = ""
        UpdateMenu(barAction.Menu, True)
    Else
        barHelper.ShowUpIndicator = True  
        barAction.Title = goStorage.sCurrentFolderName
        barAction.SubTitle = goStorage.sCurrentFolderWorkouts
        UpdateMenu(barAction.Menu, False)
    End If
End Sub

... and I have the following sub:

B4X:

private Sub UpdateMenu(Menu As ACMenu, bRoot As Boolean)
    Dim iMenu As Int = 100
    If bRoot Then
        For Each sItem As String In Array As String(moResStrings.Get(sRES_TOOLBAR_SETTINGS), _
                                                    moResStrings.Get(sRES_TOOLBAR_EXAMPLES), _
                                                    moResStrings.Get(sRES_TOOLBAR_HELP), _
                                                    moResStrings.Get(sRES_TOOLBAR_PURCHASE))
            Menu.Add(iMenu, iMenu, sItem, Null)
            iMenu = iMenu + 1
        Next
    Else
        For Each sItem As String In Array As String(moResStrings.Get(sRES_TOOLBAR_FOLDERRENAME), _
                                                    moResStrings.Get(sRES_TOOLBAR_FOLDERMOVE), _
                                                    moResStrings.Get(sRES_TOOLBAR_FOLDERCOPY), _
                                                    moResStrings.Get(sRES_TOOLBAR_FOLDERDELETE), _
                                                    moResStrings.Get(sRES_TOOLBAR_FOLDERSORTBY))
            Menu.Add(iMenu, iMenu, sItem, Null)
            iMenu = iMenu + 1
        Next
    End If
End Sub

As you can see, I'm setting the menu text with a string. But looking at my code, I can also see that code to clear the menu or to remove existing menu items is separated from code to add menu items. And I recall that when I tried to add the "Do While oMenuItem.Id >= 100" loop in the second segment into the "UpdateMenu" sub, I started to get weird exceptions.

So if the "clean it" idea doesn't work, try separating your menu.clear from your menu.add code.

Apologies - I missed the 4.2.2. I've not tried running on 4.2.2 yet.

Erel · Jun 30, 2017

Can you upload the project that is not working?

Misterbates · Jun 30, 2017

I factory reset an old phone today and ran my project on it in debug mode. It worked - android 4.1.2 on a Samsung GT-I9100.

BitsAndBytes · Jun 30, 2017

I found the solution finaly and maybe this will help to any user who want to add translated menus!

B4X:

Private acMenuPopup As ACPopupMenu

#IgnoreWarnings: 11
Sub Activity_CreateMenu(menu As ACMenu)  
   Dim item As ACMenuItem
   acActionBarLight.Menu.Add2(1,1,"show", xml.GetDrawable("ic_settings_24dp")).ShowAsAction = item.SHOW_AS_ACTION_ALWAYS
End Sub

Sub refreshMenu
   acMenuPopup.Initialize("acMenuPopup", dummypanel)  
   acMenuPopup.AddMenuItem(1,Module.arrCategoriesPanel(0),Null)
   acMenuPopup.AddMenuItem(2,Module.MenuTranslate(1),Null)
   acMenuPopup.AddMenuItem(3,Module.MenuTranslate(2),Null)
End Sub

Sub acMenuPopup_ItemClicked (item As ACMenuItem)
   Select item.Id
     Case 1
       StartActivity("settings")
     Case 2
       StartActivity("backup")
     Case 3
       StartActivity("about")
   End Select
End Sub

Sub hideMainMenu
   acActionBarLight.Menu.Clear
End Sub

Sub acActionBarLight_MenuItemClick (Item As ACMenuItem)
   Select Case Item.Id
     Case 1
       acMenuPopup.Show
   End Select
End Sub

Everything works fine now , thanks to your support

Thank you

Misterbates · Jun 30, 2017

No worries. In your solution code, how does the popup menu get shown (isn't there a "actionbar_MenuItemClick" sub somewhere)? And the hideMainMenu sub, shouldn't that be clearing the popup menu, not the acActionBarLight menu?

I am sorry i forgot it! I just add it to the code above
