Tunjukkan kepada semua orang rendering dulu
Struktur kerangka kerja:
1. Kerangka Proyek: MVP, pemuatan gambar dilakukan oleh fresco, permintaan jaringan diimplementasikan menggunakan okhttp+retrofit (enkapsulasi sendiri, tambahkan mode singleton),
2. Lengkapi penambahan data keranjang belanja (jika tidak ada data pada antarmuka, Anda dapat menambahkan data menggunakan alat antarmuka).
3. Kustomisasi tampilan untuk mengimplementasikan tombol penambahan dan pengurangan. Setiap kali Anda mengklik Tambah dan Kurangi, jumlah total dan total harga dalam item harus diubah sesuai.
4. Ketika kuantitasnya adalah 1, klik tanda minus, kuantitasnya tetap tidak berubah, dan roti panggang meminta pengguna bahwa angka minimum adalah 1.
5. Jumlah total dan total harga di bagian bawah adalah total harga dan jumlah total dalam semua item item. Jika harga kuantitas di setiap item diubah, jumlah total harga total di bagian bawah harus ditautkan ke sana.
6. Implementasikan fungsi pilihan balik pilihan tunggal, masukkan pilihan default untuk pertama kalinya, jumlah total dan total harga tidak termasuk dalam data terbawah ketika item tidak dipilih. Ketika keadaan yang dipilih diubah, jumlah total dan total harga bagian bawah dapat dimodifikasi dengan benar.
7. Klik tombol Hapus untuk menghapus item. Jumlah total dan total harga di bagian bawah dapat dimodifikasi dengan benar, dan data antarmuka akan dihapus.
