这里使用android-x解决方案,即使您使用SAW权限(系统警报窗口)具有浮动UI也应该可以工作:
@SuppressLint("InflateParams")
private fun showPopupWindow(anchor: View) {
val popupWindow = PopupWindow(anchor.context)
popupWindow.isFocusable = true
popupWindow.inputMethodMode = PopupWindow.INPUT_METHOD_NOT_NEEDED
popupWindow.contentView = LayoutInflater.from(anchor.context).inflate(R.layout.popup_layout, null)
PopupWindowCompat.showAsDropDown(popupWindow, anchor, 0, 0, Gravity.BOTTOM)
}
这是用于底部左对齐的。
如果您需要底部居中,您可以使用以下示例:
@SuppressLint("InflateParams")
private fun showPopupWindow(anchor: View) {
val popupWindow = PopupWindow(anchor.context)
popupWindow.isFocusable = true
popupWindow.inputMethodMode = PopupWindow.INPUT_METHOD_NOT_NEEDED
val inflater = LayoutInflater.from(anchor.context)
val contentView = inflater.inflate(R.layout.popup_layout, null)
contentView.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED))
popupWindow.contentView = contentView
PopupWindowCompat.showAsDropDown(popupWindow, anchor, (anchor.measuredWidth - contentView.measuredWidth) / 2, 0, Gravity.BOTTOM)
}
