B4A Library DesignSupport - Additional Material Design components

This library is a wrapper to some of the objects of Googles Design Support library.

Requirements:

This library requires B4A 6.31 or above.
From V2.32 on B4A V6.80 or newer is required. If you use an older B4A version use the V2.31 library.
AppCompat 3.30 or above is required.
The examples need some additional libraries like AHViewPager, XMLViewEx, XMLLayoutBuilder

Currently it supports:

• Snackbar - The new modern toastmessages
  
  
• TabLayout - The new material like tabs with fixed tabs and scrolling tabs feature. Works standalone or together with a ViewPager library. Supports icons as tabs and custom layouts for the tabs.
  
  
• FloatlabelEditText - An enhanced EditText object that supports a floating label, counter and error messages.
  
  
• FloatingActionButton - A very simple Floating Action Button. Has show- and hide animations but is very simple.
  
• NavigationDrawer - Material Design compliant Navigation Drawer. See NavigationView Example for detailed instructions.
  
• BottomNavigationView - Material Design compliant Bottom Navigation View. See BottomNavigationView Example for detailed instructions.
  

Installation:

Note: Please, Please read these instructions carefully. AppCompat depends on many things like a special theme with special features. Even special versions of build tools are required and last but not least there are often bugs in the Google support libraries.

I created this instructions to help you getting things ready for using AppCompat. So please follow these instructions carefully and all should work as expected and you don't have to ask in the forum.

Thanks.

1. This library depends on the AppCompat library. So do all the setup needed for AppCompat.
2. Copy the DesignSupport.xml, DesignSupport.jar and DesignSupport.aar files to your CustomLibs folder
3. Install/Update Android Support Packages with the SDK Manager.

Setup and usage:

1. Setup your project like a project that uses AppCompat library.

If you want to use the DSFloatlabelEditText object with the ErrorText or counter feature you should add the following item to your Theme:

<item name="textColorError">@color/design_textinput_error_color_light</item>

Otherwise your app will crash if the textinput reaches the maxCounter length.

If you want to use the DSNavigationDrawer object you should add the following items to your Theme:

<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>

Your support:
Creating libraries and wrappers for existing library projects is a lot of work. The use of this library is totally free and you even don't need to mention in your app that you use it.
But if you use this library in your projects and you think it is useful to you please consider to make a donation:

Thanks very much for your support.

Hy guys. In the NavigationView1_0 example a heve this error:

"java.lang.RuntimeException: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor.
Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead."

Anyone can help me?

 

[fredo]

I once had that same error when I used the Toolbar in another activity.

After a while I read the message again and found ...

set windowActionBar to false in your theme

... very helpful.

So maybe a look in the Manifest may help you

Fredo. My manifest is exactly the same

 

[fredo]

Hmmm...

Your

...the NavigationView1_0 example ...

runs on my system without an error.

Maybe first check the version numbers:

If you followed the requirements and haven't modified the example project of @corwin42 then it should run flawless.

However, it seems to be related to the Theme.

Try with this line added to the Manifest:

<item name="android:windowActionBarOverlay">false</item>

so that the relevant part looks like this:

'Tell the system that we want to draw the SystemBarBackgrounds and
'make the StatusBar transparent.
CreateResource(values, theme.xml,
<resources>
    <style name="MyAppTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">#0098FF</item>
        <item name="colorPrimaryDark">#007CF5</item>
        <item name="colorAccent">#FF5522</item>
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
        <item name="android:windowActionBarOverlay">false</item>
    </style>
</resources>
)

If this doesn't work please post the following:

a) Screenshot of the checked libraries in the Libraries manager of B4A

Something like:

b) Screenshot of the installed SDK files

Something like:

 

[Stefano Schirinzi]

problem solved tanks a lot

 

[corwin42]

Thanks. I will change the library in the first post.

Uploaded the library in the first post again. It is still version 2.10 as before. Only change is the @RaisesSynchronousEvents change in the xml file from Erel (see post #105)

 

[corwin42]

Hi @corwin42 , great work! Only one question, is possibile to change hint text color of float label, when it is not selected? I saw it black. I tried to change all color property in view, but doesn't work

This is currently not really supported. There is no way to change it programatically. I'm currently thinking about a "trick" to set a custom theme to AppCompat and DesignSupport Views. Then it may be possible to set an individual theme for a view. Currently it is not possible to change it.

I tried to create an example only with the NavigationDrawer and without the Switch and ToolBar.
The navigation drawer is show fine, but I get this error when I click in any menu option of this drawer:

Is possible to use the navigation drawer alone?
If yes, how I can fix this error?

This is the code and the project is in attached:

    NavDrawer.NavigationView.Menu.AddWithGroup2(1, 1, 1, "Home", xml.GetDrawable("ic_home_black_24dp")).Checked = True

    NavDrawer.NavigationView.Menu.SetGroupCheckable(2, True, True)       
End Sub

Sub NavDrawer_NavigationItemSelected (MenuItem As ACMenuItem, DrawerGravity As Int)
    LogColor("NavItem selected: " & MenuItem.Title, Colors.Green)

    If MenuItem.Id >= 100 Then
        ToastMessageShow(MenuItem.Id, False)
    End If
   
    NavDrawer.CloseDrawer2(DrawerGravity)
End Sub

Thanks in advance for any tips.

I found this answers to my problem. If there other way, I'll be glad to know.

Is possible to use the navigation drawer alone?

No. We need to create a second drawer to work fine.

If yes, how I can fix this error?

Create a second drawer with 1dip in width and locked it:

NavDrawer.AddSecondaryDrawer(1dip, NavDrawer.LOCK_MODE_LOCKED_CLOSED)

I use panel LoadLayout to load my bal file , but it not correct width when run in device
how can i config width of panel to 100%x with this library??
I think many people have problem with it, but dont see anybody to ask??

This question is not related to Design Support library but to AHViewpager. Please ask a question in the questions forum or in the AHViewPager thread.

It is possible set Snackbar text alignment?

 

[uniplan]

How I can set from code text and subtitle header in a DSNavigationDrawer?

How can I open the Second Drawer via a button?
