我遇到了同样的问题，我不得不深入研究这个有用的 Git 用户的项目，以弄清楚他是如何做到的。区分不同操纵杆（和方向键）的方法是使用每个方向的特定轴。
如果您非常仔细地阅读了Android 文档页面（我没有注意到它），它确实显示了您如何区分各种操纵杆及其方向：
此图像显示左操纵杆使用轴AXIS_X和AXIS_Y，而右操纵杆使用AXIS_Z和AXIS_RZ。对于方向键，我使用了 AXIS_HAT_X和AXIS_HAT_Y。我的代码（在 Kotlin 中）中的以下代码段显示了如何单独访问这些代码段：
注意：我还将搜索栏设置为 0-100 的范围，这就是为什么我在processJoystickInput().
private fun processJoystickInput(event: MotionEvent, historyPos: Int) {
val inputDevice = event.device
val newJoystickValues = floatArrayOf(
getCenteredAxis(event, inputDevice, MotionEvent.AXIS_X, historyPos),
getCenteredAxis(event, inputDevice, MotionEvent.AXIS_Y, historyPos),
getCenteredAxis(event, inputDevice, MotionEvent.AXIS_Z, historyPos),
getCenteredAxis(event, inputDevice, MotionEvent.AXIS_RZ, historyPos),
getCenteredAxis(event, inputDevice, MotionEvent.AXIS_HAT_X, historyPos),
getCenteredAxis(event, inputDevice, MotionEvent.AXIS_HAT_Y, historyPos))
// Update based on the new x and y values
val throttleSeekBar = findViewById<SeekBar>(R.id.throttle_seekBar)
val yawSeekBar = findViewById<SeekBar>(R.id.yaw_seekBar)
val pitchSeekBar = findViewById<SeekBar>(R.id.pitch_seekBar)
val rollSeekBar = findViewById<SeekBar>(R.id.roll_seekBar)
val dpadXSeekBar = findViewById<SeekBar>(R.id.dpadX_seekBar)
val dpadYSeekBar = findViewById<SeekBar>(R.id.dpadY_seekBar)
// Convert the float range (-1.00 to 1.00) to Int (0 to 100)
yawSeekBar.progress = ((newJoystickValues[0] + 1) * 50).toInt()
throttleSeekBar.progress = ((newJoystickValues[1] + 1) * 50).toInt()
rollSeekBar.progress = ((newJoystickValues[2] + 1) * 50).toInt()
pitchSeekBar.progress = ((newJoystickValues[3] + 1) * 50).toInt()
dpadXSeekBar.progress = ((newJoystickValues[4] + 1) * 50).toInt()
dpadYSeekBar.progress = ((newJoystickValues[5] + 1) * 50).toInt()
}
override fun onGenericMotionEvent(event: MotionEvent): Boolean {
// Check that the event came from a game controller
return if (event.source and(InputDevice.SOURCE_JOYSTICK) == InputDevice.SOURCE_JOYSTICK
&& event.action == MotionEvent.ACTION_MOVE) {
// Process the movements starting from the
// earliest historical position in the batch
(0 until event.historySize).forEach { i ->
// Process the event at historical position i
processJoystickInput(event, i)
}
// Process the current movement sample in the batch (position -1)
processJoystickInput(event, -1)
true
} else {
super.onGenericMotionEvent(event)
}
