How to remove buttons in layout and use buttons on the card?

I would like to add the left and right buttons to my actual card rather than being below the card. I have added them to the card in the card layout but now I can't figure out how to access the buttons in my activity. How can I go about this?

I removed the following line:

<include layout="@layout/buttons" />

From the main activity layout:

<merge
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <com.lorentzos.flingswipe.SwipeFlingAdapterView
        android:id="@+id/frame"
        android:background="#d1d1d1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:rotation_degrees="15.5"
        tools:context=".MainActivity"
        android:layout_gravity="top"/>

    <TextView
        android:id="@+id/tv_noJobsLabel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:textStyle="bold"
        android:textSize="18sp"
        android:textColor="#474747"
        android:textAlignment="center"
        tools:text="Nothing Left to Swipe!"
        android:layout_gravity="center" />

    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!--<include layout="@layout/buttons" />-->

</merge>

Now in the activity I tried the following (apply is the name of my button):

@OnClick(R.id.apply)
    public void right() {
        /**
         * Trigger the right event manually.
         */
        makeToast(MainActivity.this, "test");
    }

Now when I try to run the project in the emulator, I get the following error message and the app crashes:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.lorentzos.swipecards.example/com.lorentzos.swipecards.MainActivity}: java.lang.RuntimeException: Unable to inject views for com.lorentzos.swipecards.MainActivity@4c3946c

I think this has to do with the button not being on the main layout and it being on the actual card? How can I reference the button on the card, so that when it is pressed, it loads the next card?

Thanks for the help!
