接入声网SDK-移动和点击同时存在的FrameLayout

其实这属于View事件传递处理的范畴

移动的view就是箭头所指的本地视频窗口

下面给出移动的代码

mBinding.flVideoCallLocalVideo.setOnTouchListener(object :View.OnTouchListener{

        override fun onTouch(p0: View?, event: MotionEvent): Boolean {

            //得到事件的坐标
            val eventX = event.getRawX().toInt()
            val eventY = event.getRawY().toInt()

            when (event.getAction()) {
                MotionEvent.ACTION_DOWN -> {
                    //第一次记录lastX/lastY
                    //得到父视图的right/bottom
                    if(maxRight==0) {//保证只赋一次值
                        maxRight = mBinding.clAudioCall.getRight();
                        maxBottom = mBinding.clAudioCall.getBottom();
                    }
                    isclick = false
                    
                    lastX = eventX
                    lastY = eventY
                }
                MotionEvent.ACTION_MOVE -> {
                    isclick = true
                    //计算事件的偏移
                    val dx = eventX - lastX
                    val dy = eventY - lastY

                    LogUtils.i("ACTION_MOVE",dx.toString()+"\t"+dy)
                    //根据事件的偏移来移动imageView
                    var left: Int = mBinding.flVideoCallLocalVideo.getLeft() + dx
                    var top: Int = mBinding.flVideoCallLocalVideo.getTop() + dy
                    var right: Int = mBinding.flVideoCallLocalVideo.getRight() + dx
                    var bottom: Int = mBinding.flVideoCallLocalVideo.getBottom() + dy

                    //限制left  >=0
                    if (left < 0) {
                        right += -left
                        left = 0
                    }
                    //限制top
                    if (top < 0) {
                        bottom += -top
                        top = 0
                    }
                    //限制right <=maxRight
                    if (right > maxRight) {
                        left -= right - maxRight
                        right = maxRight
                    }
                    //限制bottom <=maxBottom
                    if (bottom > maxBottom) {
                        top -= bottom - maxBottom
                        bottom = maxBottom
                    }

                    val layoutParams = mBinding.flVideoCallLocalVideo.layoutParams as ConstraintLayout.LayoutParams
                    layoutParams.setMargins(left, top,  maxRight -right, maxBottom-bottom);    //控件相对父控件左上右下的距离
                    layoutParams.width = mBinding.flVideoCallLocalVideo.width;
                    layoutParams.height = mBinding.flVideoCallLocalVideo.height;
                    mBinding.flVideoCallLocalVideo.layoutParams = layoutParams;
                    //不能用layout，它移动后会跑回原位
                    //mBinding.flVideoCallLocalVideo.layout(left, top, right, bottom)
                    //再次记录lastX/lastY
                    lastX = eventX
                    lastY = eventY
                }
                MotionEvent.ACTION_CANCEL,MotionEvent.ACTION_UP -> {
                    
                    isclick = false
                }
                else -> {}
            }
            return isclick
        }

    })
