Android Example AppCompat with ToolBar - minimal example

In most cases AppCompat is no longer needed and will only make things more complicated.

The project attached uses the powerful AppCompat library to replace the built-in ActionBar with a more robust ToolBar.

The NavigationItemClick event is raised when the icon is clicked.

You can set ToolbarHelper.ShowUpIndicator = True to show an up arrow instead. It will raise the same event.

You can change the toolbar color in the manifest editor.

Edit: depending on your Android SDK version, you might get this error:

java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/arch/core/executor/ArchTaskExecutor;

The solution is to add this line in the main activity:
B4X:
#AdditionalJar: androidx.arch.core:core-runtime

Now with a more colorful popup menu:

SS-2017-06-11_08.19.16.png


The color is set in the manifest editor:
B4X:
<style name="ToolbarMenu" parent="Base.ThemeOverlay.AppCompat.ActionBar">
    <item name="android:textColorPrimary">#fff</item>
    <item name="android:colorBackground">#0098FF</item>
   </style>

And is set with this code:
B4X:
Dim jo As JavaObject = ACToolBarLight1
Dim xl As XmlLayoutBuilder
jo.RunMethod("setPopupTheme", Array(xl.GetResourceId("style", "ToolbarMenu")))

Hi Guys,

any idea what could this error be "invalid resource directory name: C:\Users\Admin\Documents\Tutorials And Samples\B4a Samples\AppCompatWithDynamicMenuAndBadge\AppCompat\Objects\bin\extra\res2\res/values-b+sr+Latn"

Thanks

I'm using the latest version of B4A Version 7.01.
Talking about B4A you are right. But Erel said that the issue is related to the installed Build-Tools. It should be a NEWER one than you are using.

Install the newer 25.0.3.
DEINSTALL all versions <25
