Include in your project

Using Maven

The ActionItemBadge Library is pushed to [Maven Central], so you just need to add the following dependency to your build.gradle.

dependencies {
	implementation 'com.mikepenz:actionitembadge:4.0.0'

	//SUB-DEPENDENCIES
	//Android-Iconics - used to provide an easy API for icons 
	implementation 'com.mikepenz:iconics-core:{latestVersion}@aar'
}

Additional dependency for the icon font

If you are going to use the icon font you will have to add additional dependency for the font. You can find all available addons here: https://github.com/mikepenz/Android-Iconics#2-choose-your-desired-fonts

UPGRADE NOTES

< 4.0.0

If you come from a version prior 4.0.0 you will have to upgrade to AndroidX and Iconics v4

< 3.0.0

If you come from a version prior 3.0.0 you will have to rename some classes, and the default styles also found a new place. Just check out the updated sample app for all the changes.

Usage

menu.xml

Create your menu.xml as you would do normally and add the app:actionLayout param. It is also a good idea to set showAsAction="always" (The badge can only be shown in the actionbar)

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/item_samplebadge"
        app:actionLayout="@layout/menu_action_item_badge"
        app:showAsAction="always"
        android:title="@string/sample_1"/>
</menu>

Activity

Override the onCreateOptionsMenu method

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);

	    //you can add some logic (hide it if the count == 0)
        if (badgeCount > 0) {
            ActionItemBadge.update(this, menu.findItem(R.id.item_samplebadge), FontAwesome.Icon.faw_android, ActionItemBadge.BadgeStyles.DARK_GREY, badgeCount);
        } else {
            ActionItemBadge.hide(menu.findItem(R.id.item_samplebadge));
        }

	    //If you want to add your ActionItem programmatically you can do this too. You do the following:
        new ActionItemBadgeAdder().act(this).menu(menu).title(R.string.sample_2).itemDetails(0, SAMPLE2_ID, 1).showAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS).add(bigStyle, 1);
        return super.onCreateOptionsMenu(menu);
    }

If you want to update the item itself you can do the required stuff in the onOptionsItemSelected method and call invalidateOptionsMenu() afterwards.

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == R.id.item_samplebadge) {
            Toast.makeText(this, R.string.sample_3, Toast.LENGTH_SHORT).show();
            badgeCount--;
            ActionItemBadge.update(item, badgeCount);
            return true;
        } else if (id == SAMPLE2_ID) {
            Toast.makeText(this, R.string.sample_4, Toast.LENGTH_SHORT).show();
        }
        return super.onOptionsItemSelected(item);
    }
