如何将活动的变量传递给BottomNavigationView的片段？

Bundle bundle = new Bundle();
bundle.putString("activityVariable", activityVariable);

bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        Fragment fragment = new YourFragment();
        fragment.setArguments(bundle);
        // 其他处理逻辑
        return true;
    }
});

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Bundle bundle = getArguments();
    if (bundle != null) {
        String activityVariable = bundle.getString("activityVariable");
        // 使用活动的变量进行处理
    }
}
