Configure Tabs on Android
With your Android directories in good shape, you can now configure the tabs. Here’s how:
- Update the layout XML for tabs.
- Manage tabs with a model.
- Initialize the tab bar.
Update the Layout XML for Tabs
Start by opening activity_main.xml. Here’s a reminder of what that file looks like now:
| | <?xml version="1.0" encoding="utf-8"?> |
| | <androidx.fragment.app.FragmentContainerView |
| | xmlns:android="http://schemas.android.com/apk/res/android" |
| | xmlns:app="http://schemas.android.com/apk/res-auto" |
| | android:id="@+id/main" |
| | android:name="dev.hotwire.navigation.navigator.NavigatorHost" |
| | android:layout_width="match_parent" |
| | android:layout_height="match_parent" |
