【问题描述】:
我已经成功地将底部导航与最新的android架构导航组件集成在一起。以下是我的完整代码。
- 导航
<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/mobile_navigation"
app:startDestination="@+id/navigation_home">
<fragment
android:id="@+id/navigation_home"
android:name="in.zedone.bottomsample.ui.home.HomeFragment"
android:label="@string/title_home"
tools:layout="@layout/fragment_home" />
<fragment
android:id="@+id/navigation_saloons"
android:name="in.zedone.bottomsample.ui.saloons.SaloonsFragment"
android:label="@string/title_saloon"
tools:layout="@layout/fragment_saloons" />
<fragment
android:id="@+id/navigation_offers"
android:name="in.zedone.bottomsample.ui.offers.OffersFragment"
android:label="@string/title_offer"
tools:layout="@layout/fragment_offers" />
<fragment
android:id="@+id/navigation_account"
android:name="in.zedone.bottomsample.ui.account.AccountFragment"
android:label="@string/title_account"
tools:layout="@layout/fragment_account" />
</navigation>
- 底部导航视图
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="@+id/nav_view"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="0dp"
android:layout_marginEnd="0dp"
android:background="?android:attr/windowBackground"
app:labelVisibilityMode="labeled"
app:itemTextAppearanceActive="@style/BottomNavigationView.Active"
app:itemTextAppearanceInactive="@style/BottomNavigationView"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="@menu/bottom_nav_menu" />
- 主要活动
BottomNavigationView navView = findViewById(R.id.nav_view);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
R.id.navigation_home, R.id.navigation_saloons, R.id.navigation_offers,R.id.navigation_account)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
NavigationUI.setupWithNavController(navView, navController);
现在如何在底部导航中选择每个选项卡/片段时添加过渡/动画?
