TalkBack describes main FAB as "unlabeled button"

Step 1: Are you in the right place?

• I have verified there are no duplicate active or recent bugs, questions, or requests
• I have verified that I am using the latest version of the library.

Step 2: Describe your environment

• Library version: view-3.3.0
• Android version: 12
• Support library version: ? (not sure what this means)
• Device brand: Samsung
• Device model: Galaxy S10

Step 3: Describe the problem:

Steps to reproduce:

1. Set contentDescription of SpeedDialView
2. Enable TalkBack
3. Press on main FAB
4. Observe "unlabeled button"

Observed Results:

• When using TalkBack, main FAB is described as "unlabeled button."

Expected Results:

• When using TalkBack, main FAB would be described as "Apply action button."

Relevant Code:

<com.leinardi.android.speeddial.SpeedDialView
            android:id="@+id/fabSD"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:accessibilityTraversalBefore="@android:id/list"
            android:contentDescription="@string/apply_action"
            android:visibility="gone"
            app:sdMainFabClosedSrc="@drawable/ic_fab_edit"
            app:sdOverlayLayout="@id/fabSDOverlay" />

I think the problem is that SpeedDialView is not the FAB itself, but just a LinearLayout. Thus, the contentDescription is being applied to the SpeedDialView and not the (main) FAB that's IN the SpeedDialView. (If that's not the problem, then I don't know what is.)

Start with the SpeedDialView implementation and trace how its main FAB receives accessibility content. Reproduce the issue with TalkBack using the provided XML and verify that the main FAB is announced as “Apply action button” rather than “unlabeled button.”
