Android上如何连接多个游戏手柄？

Question

根据https://developer.android.com/training/game-controllers/multiple-controllers.html，Android似乎支持多个游戏手柄。实际上，当同时发生多个输入设备事件时并不起作用。例如，当玩家1和玩家2同时按下向上按钮时，dipathKeyEvents会像下面这样发生。

D/dispatchKeyEvent(12736): device:6,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:6,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:6,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:6,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:1,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:1,action:ACTION_UP,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:1,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:1,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP

并且设备6的ACTION_UP从未发生。

它们应该像这样

D/dispatchKeyEvent(12736): device:6,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:1,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:6,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:1,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:6,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP D/dispatchKeyEvent(12736): device:1,action:ACTION_DOWN,keyCoe:KEYCODE_DPAD_UP

有人能够管理多个控制器吗? NativeActivity解决了这个问题吗?

我的环境是

- 设备：NVIDIA Shield电视 - 控制器1：Shield controller - 控制器2：通过USB连接的Playstation 3控制器 - 操作系统：Android TV

Answer 1

Android 中存在一个错误，导致来自一个控制器的 onKeyDown/onKeyUp 事件有时被错误地识别为来自另一个控制器。这仅发生在 D-pad 上，其他按钮正常工作。您可以通过实现 onGenericMotionEvent 并自己处理 D-pad 事件（AXIS_HAT_X、AXIS_HAT_Y）来解决此错误。有关错误和解决方法的更多信息：https://playjam.com/develop/guides/controller
