2. Affects scrolling, when scrolling forward it suddenly back to nearby selected text position

fun TextView.customMenuCallBack() {
    var selectAll = false
    customSelectionActionModeCallback = object : ActionMode.Callback {
        override fun onCreateActionMode(mode: ActionMode?, menu: Menu?): Boolean {
            return true
        }

        override fun onPrepareActionMode(mode: ActionMode?, menu: Menu?): Boolean {
            return true
        }

        override fun onActionItemClicked(mode: ActionMode?, item: MenuItem?): Boolean {
            item?.let {
                return when (it.itemId) {
                    android.R.id.selectAll -> {
                        selectAll = true
                        false
                    }

                    android.R.id.copy -> {
                        if (selectAll) {
                            //TODO set content
                            try {
                                val clipboard: ClipboardManager = context.getSystemService(AppCompatActivity.CLIPBOARD_SERVICE) as ClipboardManager
                                val clip = ClipData.newPlainText(context.toString(), content)
                                clipboard.setPrimaryClip(clip)
                            } catch (e: Exception) {
                                e.printStackTrace()
                            }
                        }
                        //fixed first issue
                        mode?.finish()
                        //fixed second issue
                        clearFocus()
                        //make custom action work return true
                        true
                    }
                    else -> {
                        false
                    }
                }
            }
            return false
        }

        override fun onDestroyActionMode(mode: ActionMode?) {

        }

    }
}

update： Custom my NestedScrollView2:NestedScrollView and override

  override fun requestChildFocus(child: View?, focused: View?) {
     //do nothing prevent focused issued
  }
