Saya sedang mengerjakan aplikasi Android, dimana ada 2 tipe pengguna. Saat pengguna mendaftar atau masuk ke sistem, mereka diarahkan ke Layar Beranda yang sama, dan melihat fragmen tampilan berbeda yang diperluas berdasarkan jenisnya. Saya dapat mencapai ini menggunakan Preferensi Bersama saat pertama kali mendaftar. Satu-satunya masalah saya adalah, jika pengguna keluar dan kemudian mencoba masuk lagi, apa pun jenis penggunanya, layar beranda yang sama akan dimuat. Saya ragu, Aktivitas menggunakan set preferensi Bersama yang terakhir.
Dalam fragmen saya, berdasarkan tipe pengguna, saya mengembangkan file xml yang sesuai. Persyaratan saya adalah, ketika pengguna masuk, bagaimana cara mengembangkan file xml yang sesuai, yaitu. bagaimana cara mendapatkan preferensi Bersama di SignInActivity untuk memuat fragmen xml yang sesuai.
Inilah yang telah saya coba sejauh ini.

Saat pengguna masuk ke aplikasi, bagaimana cara memuat masing-masing fragmen xml? Apa yang saya lewatkan? Mohon bantuannya.
