对于BottomNavigationView的最后一个标签,我希望内容位于状态栏下方,并使状态栏完全透明。这可以按预期工作,但是当选择最后一个选项卡时,BottomNavigationView会跳起,在底部留下一个空白区域。
在SO中有类似的主题说要将fitWindowSystems设置为false。我尝试过,但没有帮助。任何帮助表示赞赏。

对于将来遇到问题的人可能有用。 我通过添加
解决了这个问题ViewCompat.requestApplyInsets(view)
我片段的onActivityCreated
方法。
view
-片段的根视图
就我而言,它看起来像:
科特琳
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
view?.let {
ViewCompat.requestApplyInsets(it)
}
}
JAVA
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
View view = getView()
if(view != null){
ViewCompat.requestApplyInsets(view)
}
}

问题的解决方法是将bottomNavigationView setOnApplyWindowsListener设置为null:
setOnApplyWindowInsetsListener(null)
在为我的 AR Core Sceneform 片段实现底部导航视图时,我遇到了这个问题。
