推荐答案

TIZEN (2.3) 中有两种类型的应用程序

There are two type of application is exist in TIZEN (2.3)

如果您制作网络应用程序，

If you make web application,

document.addEventListener('tizenhwkey', function(e) {
    if(e.keyName == "back") {
        try {
            tizen.application.getCurrentApplication().exit();
        } catch (error) {
            console.error("getCurrentApplication(): " + error.message);
        }
    }
});

但是如果你想要原生应用程序，你可以通过 EFL 扩展 API

but if you want native application, you can get back button event with EFL Extension API

#include <efl_extension.h>

static void
win_back_cb(void *data, Evas_Object *obj, void *event_info)
{
    appdata_s *ad = data;
    /* Let window go to hide state. */
    elm_win_lower(win);
}

eext_object_event_callback_add(ad->win, EEXT_CALLBACK_BACK, win_back_cb, ad);
