Resep Interop

Resep ini menunjukkan cara menggunakan AndroidFragment dan AndroidView dalam aplikasi Navigation3.

Fitur

  • AndroidFragment: Menunjukkan cara menyematkan Fragment di dalam tujuan Composable.
  • AndroidView: Menunjukkan cara menyematkan View Android klasik di dalam tujuan Composable.

Komponen Utama

  • InteropActivity: Aktivitas utama yang menghosting navigasi.
  • MyCustomFragment: Fragmen sederhana yang digunakan dalam contoh.
  • AndroidFragment<T>: Composable yang menghosting Fragment.
  • AndroidView: Composable yang menghosting Tampilan Android.

Penggunaan

  1. Jalankan InteropActivity.
  2. Layar awal menampilkan Fragment.
  3. Klik "Buka Tampilan" untuk membuka layar yang menampilkan TextView.
