如何向导航视图选项卡添加意图？

Question

所以我有一个导航视图，它从左侧滑动，带有一个名为蓝牙的选项卡。我希望该蓝牙按钮与另一个具有所有蓝牙功能的类连接。有没有办法和意图让我连接到那个功能类？抱歉，如果我不是很具体，我是 Android Studio 初学者。

我的导航视图与按钮：

我的主要课程：

public class PantallaDatos extends AppCompatActivity {

private DrawerLayout drawer;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_pantalla_datos);

    Toolbar toolbar = findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    drawer = findViewById(R.id.drawer_layout);

    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, 
    R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

    ViewPager2 viewPager2 = findViewById(R.id.viewPager);
    viewPager2.setAdapter(new DatosPagerAdapter(this));

    TabLayout tabLayout = findViewById(R.id.tabLayout);
    TabLayoutMediator tabLayoutMediator = new TabLayoutMediator(
            tabLayout, viewPager2, new TabLayoutMediator.TabConfigurationStrategy(){

        @Override
        public void onConfigureTab(@NonNull TabLayout.Tab tab, int position) {

            switch(position){
                case 0:{
                    tab.setText("Medidas");
                    break;
                }
                case 1:{
                    tab.setText("Registros");
                    break;
                }
                case 2:{
                    tab.setText("Graficos");
                    break;
                }
            }
        }
    });
    tabLayoutMediator.attach();
}

@Override
public void onBackPressed() {
    if(drawer.isDrawerOpen(GravityCompat.START)){
        drawer.closeDrawer(GravityCompat.START);
    }else{
        super.onBackPressed();
    }

   }
 }

具有我想要连接到该按钮的所有功能的类（简化）：

可能不是您专门寻找的，但如果您想通过启动另一个活动来处理它，因此使用另一个布局。你只需要设置一个意图并开始一个活动。您都可以将活动中的信息传递给新活动，下面是如何执行此操作的示例，希望对您有所帮助。

Intent myIntent = new Intent(myActivity.this, NewActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("Extra_info", somefunction.extrainfo());//Pass extra info as a string
        myIntent.putExtras(bundle);
        myActivity.this.startActivity(myIntent);//Run the new activity
