根据 github 来源已弃用：BottomNavigationView.setOnNavigationItemSelectedListener

在其评论中，您可以阅读：

@deprecated Use {@link NavigationBarView#setOnItemSelectedListener(OnItemSelectedListener)}
   *     instead.

所以使用NavigationBarView.setOnItemSelectedListener从它的基类：

  /**
   * Set a listener that will be notified when a navigation item is selected. This listener will
   * also be notified when the currently selected item is reselected, unless an {@link
   * OnItemReselectedListener} has also been set.
   *
   * @param listener The listener to notify
   * @see #setOnItemReselectedListener(OnItemReselectedListener)
   */
  public void setOnItemSelectedListener(@Nullable OnItemSelectedListener listener) {
    selectedListener = listener;
  }

另请参阅此提交

因为它解释了有关此更改的混淆：

侦听器已被弃用，而支持
NavigationBarView#OnItemSelectedListener和
NavigationBarView#OnItemReselectedListener，但从未添加弃用文档，因此不清楚开发人员应该使用什么来代替。

你可以试试setonItemSelectedListener。它的工作原理与setOnNavigationItemSelectedListener()[在 android 11 中测试]

bnv.setOnItemSelectedListener(new NavigationBarView.OnItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            int id = item.getItemId();
            switch(id){
              //check id
            }
            return true;
        }
    });

科特林：

bnv.setOnItemSelectedListener { item ->
            when (item.itemId) {
            }
            true
        }
