    // 這里可以使用 boxRect.value 獲取到Box組件的位置和大小信息

    // boxRect.value.right - 右側(cè)位置
    // boxRect.value.bottom - 底部位置
    // boxRect.value.width - 寬度
    // boxRect.value.height - 高度
}

? boxRect.value = coordinates.boundsInParent() 是針對當(dāng)前父布局。如果想針對整個手機(jī)可以用文章來源地址http://www.zghlxwxcb.cn/news/detail-715969.html

            val position = coordinates.positionInWindow()
                                val top =  position.y-StatusBarUtil.getStatusBarHeight(context)
                                viewModel.boxRect.value = Rect(
                                    left = position.x,
                                    top = top,
                                    right = position.x + coordinates.size.width,
                                    bottom = top + coordinates.size.height
                                )
                                LL.e(
                                    TAG,
                                    " \"Left: ${viewModel.boxRect.value.left} Top: ${viewModel.boxRect.value.top} Right: ${viewModel.boxRect.value.right} Bottom: ${viewModel.boxRect.value.bottom}\""
                                )

    //獲取狀態(tài)欄高度
    fun getStatusBarHeight(context: Context): Int {
        var result: Int = 0
        val resourceId: Int = context.getResources().getIdentifier(
            "status_bar_height", "dimen", "android"
        )
        if (resourceId > 0) {
            result = context.getResources().getDimensionPixelSize(resourceId)
        }
        return result
    }
