Here's a class that debounce's clicks for View and MenuItem.

import android.os.SystemClock;
import android.support.annotation.NonNull;
import android.support.v7.widget.Toolbar.OnMenuItemClickListener;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;

/**
 * Debounce's click events to prevent multiple rapid clicks.
 * 

 * When a view is clicked, that view and any other views that have applied {@link #shareDebounce} to them,
 * will have subsequent clicks ignored for the set {@link #DEBOUNCE_DURATION_MILLIS duration}.
 */
public final class ClickEvent {
    private static final long DEBOUNCE_DURATION_MILLIS = 1000L;
    private long debounceStartTime = 0;

    /**
     * Wraps the provided {@link OnClickListener OnClickListener} in a {@link ClickEvent}
     * that will prevent multiple rapid clicks from executing.
     * 

     * Usage:
     * 
View.setOnClickListener(ClickEvent.debounce((OnClickListener) v -> // click listener runnable))
     */
    public static OnClickListener debounce(@NonNull OnClickListener onClickListener) {
        return new ClickEvent().wrapOnClickListener(onClickListener);
    }

    /**
     * Wraps the provided {@link OnMenuItemClickListener OnMenuItemClickListener} in a
     * that will prevent multiple rapid clicks from executing.
     * 

     * Usage:

     */
    public static OnMenuItemClickListener debounce(@NonNull OnMenuItemClickListener onClickListener) {
        return new ClickEvent().wrapOnClickListener(onClickListener);
    }

    /**
     * Allows the debounce to be shared between views to prevent multiple rapid clicks between views.
     * 

     * Usage:
     * 
     *     ClickEvent clickEvent = new ClickEvent();
     *     View1.setOnClickListener(clickEvent.shareDebounce((OnClickListener) v -> // click listener runnable for View1))
     *     View2.setOnClickListener(clickEvent.shareDebounce((OnClickListener) v -> // click listener runnable for View2))

    public OnClickListener shareDebounce(@NonNull OnClickListener listener) {
        return wrapOnClickListener(listener);
    }
