我正在构建一个我有BottomNavigationView的应用程序.一切正常,直到我进入活动.

导航是这样的:

问题是它有这个默认动画,因此它每次都会推动活动元素高于其余元素.

另一个例子:

所以我的问题是如何摆脱这个默认动画,当我在它们之间切换时,每个项目都是对齐的？

我的代码:

public class MainActivity extends AppCompatActivity {
    private BottomNavigationView bottomNavigationView;
    private Fragment fragment;
    private FragmentManager fragmentManager;
    private FragmentTransaction transaction;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        setContentView(R.layout.activity_main);

                switch (item.getItemId()){
                    case R.id.action_card_deck:{
                        Toast.makeText(MainActivity.this, "Card Deck Selected", Toast.LENGTH_SHORT).show();
                        fragment = new CardDeckFragment();
                        break;
                    }
                    case R.id.action_favorites:{ …
