在我的Android应用程序中,用户可以选择他想要查看的地方的类别(咖啡馆,餐馆......).

当我使用以下网址时,我从google-places-api获得带有next_page_token的结果:

https://maps.googleapis.com/maps/api/place/textsearch/json?query=cafe+in+Elfde-Liniestraat%2C+Hasselt%2C+Belgium&pagetoken=ClRHAAAAqYa7IpwMQH3q1DyinfsMnkuOaZg8wQrp0pvzarv13pwqruqT2YfaEry6v_d-L4d_TC13G6iHuPz-rc1KbI6XRE01rB5CuXcHISu-CI_CaKESEMUxSjHhHDNee4xbr2tPEZcaFPvO6xlRDjs-5AixyD9vamWwTGlU&sensor=true&key=<mykey>

        String myTypes = "";
