Start Activity with a Checkbox in RecyclerView

I would start an Activity on check of my Checkbox in a RecyclerView. I've already set the Checkbox and the OnClickListener in my RecyclerView Adapter, now i have to start the activity in my main. I know i should override and declare as follow:

@Override
public void mClick(View v, int position) {
Intent i = new Intent(FrammentoUno.this, SQL_Main.class);
startActivity(i);
}

but i don't know where, in my Activity. I'll probably have to set my setListener as follow

 MyAdapter.setListner(this);

but i don't understand where. Here my Main and my Adapter:

FrammentoUno.java (main)

public class FrammentoUno extends AppCompatActivity {


private RecyclerView GetAllAllarmiListView;
/**
 * ATTENTION: This was auto-generated to implement the App Indexing API.
 * See http://ift.tt/1Shh2Dk for more information.
 */
private GoogleApiClient mClient;
private Uri mUrl;
private String mTitle;
private String mDescription;

private Button frammentoUno, frammentoDue;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fragment_one);

    addListenerOnButton();


    this.GetAllAllarmiListView = (RecyclerView) this.findViewById(R.id.GetAllAllarmiListView);

    new GetAllAllarmiTask().execute(new ApiConnector());

    mClient = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
    mUrl = Uri.parse("android-app://com.example.andrea/http/host_path");
    mTitle = "Standard Poodle";
    mDescription = "The Standard Poodle stands at least 18 inches at the withers";



    LayoutInflater factory = LayoutInflater.from(this);
    final View view = factory.inflate(R.layout.get_all_allarmi_list_view_cell, null);

    setListAdapter(new JSONArray());
}


public void addListenerOnButton() {

    frammentoUno = (Button) findViewById(R.id.frammentoUno);
    frammentoDue = (Button) findViewById(R.id.frammentoDue);

    frammentoUno.setOnClickListener(new View.OnClickListener() {

        //Run when button is clicked
        @Override
        public void onClick(View v) {
            Intent i = new Intent(FrammentoUno.this, FrammentoUno.class);

            startActivity(i);
            Toast.makeText(FrammentoUno.this, "Allarmi Generali",
                    Toast.LENGTH_LONG).show();

        }
    });

    frammentoDue.setOnClickListener(new View.OnClickListener() {
        //Run when button is clicked
        @Override
        public void onClick(View v) {
            Intent i = new Intent(FrammentoUno.this, FrammentoDue.class);

            startActivity(i);
            Toast.makeText(FrammentoUno.this, "Controllo Ultimi Allarmi",
                    Toast.LENGTH_LONG).show();
