Answer 1

首先，您可以借助getActivity（）方法在其片段中获取Activity的实例。使用此实例从您的片段中调用活动的任何方法，如下所示： -

((MainActivity) getActivity()).methodName();

其次，我建议您将该栏转换为NavigationDrawer，通过为您提供更清晰的用户界面以及更清晰的过渡，您将从中受益。

主活动

public class HomeActivity extends AppCompatActivity {

    public static BottomNavigationView mNavigationView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);

        //-----------------------------------------------| Bottom navigation menu
        mNavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation);
        mNavigationView.setOnNavigationItemSelectedListener(new ActionHandler());

    }

    private class ActionHandler implements BottomNavigationView.OnNavigationItemSelectedListener {
        //-----------------------------------------------| Bottom navigation menu listener
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            switch (item.getItemId()) {
                case R.id.action_menu:
                    getSupportFragmentManager().beginTransaction().setCustomAnimations(R.anim.enter_from_left, 0).add(android.R.id.content, new MenuFragment(), "myFragmentTag").addToBackStack("tag").commit(); // without FrameLayout
                    return true;
                case R.id.action_account:
                    //
                    return true;
            }
            return false;
        }
    }

}
