1. There are three methods to process key events in Android gridview:
Public Boolean onkeydown (INT keycode, keyevent event)
Public Boolean onkeyup (INT keycode, keyevent event)
Public Boolean onkeylongpress (INT keycode, keyevent event)
Obviously, long-press events are handled in the onkeylongpress function.
If the time of the gridview is long, the corresponding
A TSMC 10nm technology gradually mature, Gaotong 835, MediaTek Helio X30 and Kirin 970 are their customers, so that mobile phone performance is expected to blowout again. However, CPU and GPU performance up, memory can not drag it? No 8GB memory, who has the nerve to match the next generation of processors?
By the way, in addition to these new flagship processors, existing processors like Xiao 821 and 653 have added support for 8GB of memory, so the 8GB memory handsets should be available soone
