Saya rasa saya mencapainya: Anda benar-benar dapat menggunakan fragmen dan menambahkan ikon pencarian ke panel tindakan sehingga pencarian dimungkinkan di dalam fragmen. Caranya adalah dengan menggunakan panel tindakan, tampilan tindakan, pendengar untuk itu, loader dan adaptor tentunya.
Ini bekerja cukup baik meskipun sepenuhnya mem-bypass mekanisme pencarian platform android (tetapi bisa diselesaikan dengan beberapa pekerjaan untuk menemukan apa yang dijelaskan oleh @Alex Lockwood dan meneruskan pencarian ke fragmen). Itu tidak akan bereaksi terhadap maksud seperti yang diharapkan dalam kasus suatu kegiatan, tetapi berfungsi: pengguna dapat mencari di dalam fragmen.
Ini kodenya:
