底部导航视图项中的片段

Question

如何在底部导航视图的特殊选项卡中放入一些片段。我可以使用NavHost导航组件吗？谢谢，抱歉英语不好。

Answer 1

因此，如果我理解正确，则希望显示另一个片段中的一个片段。 一种选择是使用FragmentTransation。

如果您使用Kotlin：

// Replace YourNextFragment with fragment class name you want to show
val fragment: YourNextFragment = YourNextFragment()
val transaction = parentFragmentManager.beginTransaction()
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN)
// R.id.container should be replaced with resource ID of FrameLayout or fragment
// tag that you use to display fragments
transaction.replace(R.id.container, fragment, fragment::class.java.simpleName)
transaction.addToBackStack(fragment::class.java.simpleName)
transaction.commit()

如果您使用Java：

// Replace YourNextFragment with fragment class name you want to show
YourNextFragment fragment = YourNextFragment();
FragmentTransation transaction = getParentFragmentManager().beginTransaction();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
// R.id.container should be replaced with resource ID of FrameLayout or fragment
// tag that you use to display fragments
transaction.replace(R.id.container, fragment, fragment.class.getSimpleName());
transaction.addToBackStack(fragment.class.getSimpleName());
transaction.commit();
