class JoystickControl(context: Context, attrs: AttributeSet?) : View(context, attrs) { private val paint = Paint(Paint.ANTI_ALIAS_FLAG) private var centerX = 0f private var centerY = 0f private var radius = 0f private var thumbX = 0f private var thumbY = 0f private var onJoystickChangeListener: OnJoystickChangeListener? = null interface OnJoystickChangeListener { fun onJoystickChanged(thumbX: Float, thumbY: Float) } fun setOnJoystickChangeListener(listener: OnJoystickChangeListener) { onJoystickChangeListener = listener } override fun onSizeChanged(w: Int, h: Int, oldw: Int, oldh: Int) { centerX = w / 2f centerY = h / 2f radius = min(w, h) / 2f * 0.8f } override fun onDraw(canvas: Canvas) { paint.color = Color.GRAY canvas.drawCircle(centerX, centerY, radius, paint) paint.color = Color.RED val thumbRadius = radius / 5f canvas.drawCircle(thumbX + centerX, thumbY + centerY, thumbRadius, paint) } override fun onTouchEvent(event: MotionEvent): Boolean { when (event.action) { MotionEvent.ACTION_DOWN, MotionEvent.ACTION_MOVE -> { val distance = sqrt((event.x - centerX) * (event.x - centerX) +(event.y - centerY) * (event.y - centerY)) if (distance < radius) { thumbX = event.x - centerX thumbY = event.y - centerY invalidate() onJoystickChangeListener?.onJoystickChanged(thumbX, thumbY) } else { val angle = atan2(event.y - centerY, event.x - centerX) thumbX = cos(angle) * radius thumbY = sin(angle) * radius invalidate() onJoystickChangeListener?.onJoystickChanged(thumbX, thumbY) } } MotionEvent.ACTION_UP -> { thumbX = 0f thumbY = 0f invalidate() onJoystickChangeListener?.onJoystickChanged(thumbX, thumbY) } } return true } }我想加入传递游戏手柄参数的代码

你可以在OnJoystickChangeListener接口中添加一个新的方法，用于传递手柄参数，如下所示：

interface OnJoystickChangeListener {
    fun onJoystickChanged(thumbX: Float, thumbY: Float)
    fun onJoystickParamsChanged(params: String)
}

然后，你可以在onTouchEvent方法中获取手柄参数，并且在onJoystickParamsChanged方法中将其传递给监听器：

override fun onTouchEvent(event: MotionEvent): Boolean {
    when (event.action) {
        MotionEvent.ACTION_DOWN, MotionEvent.ACTION_MOVE -> {
            val distance = sqrt((event.x - centerX) * (event.x - centerX) +
                    (event.y - centerY) * (event.y - centerY))
            if (distance < radius) {
                thumbX = event.x - centerX
                thumbY = event.y - centerY
                invalidate()

                // Pass joystick position and parameters to listener
                onJoystickChangeListener?.onJoystickChanged(thumbX, thumbY)
                onJoystickChangeListener?.onJoystickParamsChanged("PARAMS")
            } else {
                val angle = atan2(event.y - centerY, event.x - centerX)
                thumbX = cos(angle) * radius
                thumbY = sin(angle) * radius
                invalidate()

                // Pass joystick position and parameters to listener
                onJoystickChangeListener?.onJoystickChanged(thumbX, thumbY)
                onJoystickChangeListener?.onJoystickParamsChanged("PARAMS")
            }
        }
        MotionEvent.ACTION_UP -> {
            thumbX = 0f
            thumbY = 0f
            invalidate()

            // Pass joystick position and parameters to listener
            onJoystickChangeListener?.onJoystickChanged(thumbX, thumbY)
            onJoystickChangeListener?.onJoystickParamsChanged("PARAMS")
        }
    }
    return true
}

请注意，我在此处将参数设置为“PARAMS”，你需要将其替换为你想要传递的实际参数。
