我想在可绘制图标下方添加一个Textview
。
我的代码是
override fun onChildDraw(
c: Canvas,
recyclerView: RecyclerView,
viewHolder: RecyclerView.ViewHolder,
dX: Float,
dY: Float,
actionState: Int,
isCurrentlyActive: Boolean
) {
val itemView = viewHolder.itemView
val itemHeight = itemView.bottom - itemView.top
val isCanceled = dX == 0f && !isCurrentlyActive
if (isCanceled) {
clearCanvas(
c,
itemView.right + dX,
itemView.top.toFloat(),
itemView.right.toFloat(),
itemView.bottom.toFloat()
)
super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive)
return
}
background.setColor(backgroundColor)
background.cornerRadius = 10f
background.setBounds(itemView.right + dX.toInt(), itemView.top, itemView.right, itemView.bottom)
background.draw(c)
// Calculate position of delete icon
val deleteIconTop = itemView.top + (itemHeight - intrinsicHeight) / 2
val deleteIconMargin = (itemHeight - intrinsicHeight) / 4
val deleteIconLeft = itemView.right - deleteIconMargin - intrinsicWidth
val deleteIconRight = itemView.right - deleteIconMargin
val deleteIconBottom = deleteIconTop + intrinsicHeight
// Draw the delete icon
deleteIcon?.setBounds(deleteIconLeft, deleteIconTop, deleteIconRight, deleteIconBottom)
deleteIcon?.draw(c)
val rect = RectF( itemView.right + dX,
itemView.top.toFloat(),
itemView.right.toFloat(),
itemView.bottom.toFloat())
super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive)
}
