Membuat panel aplikasi bawah
Gunakan kode berikut untuk membuat panel aplikasi bawah yang berisi empat tombol ikon,
dan tombol tindakan mengambang:
@ComposablefunBottomAppBarExample(){Scaffold(bottomBar={BottomAppBar(actions={IconButton(onClick={/* do something */}){Icon(Icons.Filled.Check,contentDescription="Localized description")}IconButton(onClick={/* do something */}){Icon(Icons.Filled.Edit,contentDescription="Localized description",)}IconButton(onClick={/* do something */}){Icon(Icons.Filled.Mic,contentDescription="Localized description",)}IconButton(onClick={/* do something */}){Icon(Icons.Filled.Image,contentDescription="Localized description",)}},floatingActionButton={FloatingActionButton(onClick={/* do something */},containerColor=BottomAppBarDefaults.bottomAppBarFabColor,elevation=FloatingActionButtonDefaults.bottomAppBarFabElevation()){Icon(Icons.Filled.Add,"Localized description")}})},){innerPadding->
Text(modifier=Modifier.padding(innerPadding),text="Example of a scaffold with a bottom app bar.")}}
Scaffold luar yang memiliki bottomBar yang ditetapkan.
Implementasi bottomBar yang berisi daftar tindakan.
Tindakan yang merupakan implementasi IconButton yang berisi
Icon untuk teks deskripsi gambar dan konten, masing-masing dengan lambda onClick
untuk melakukan tindakan ini.
Anda dapat meneruskan composable untuk parameter utama berikut:
actions: serangkaian ikon yang muncul di sisi kiri panel. Tindakan ini
biasanya berupa tindakan utama untuk layar tertentu, atau item navigasi.
floatingActionButton: tombol tindakan mengambang yang muncul di
sisi kanan panel.
