How to override listItem icon tooltip?

Question

I am trying to change tooltip of icon which is in core: ListItem.

tooltip property of listItem is changing tooltip of whole item which is not what im looking for.

<core:ListItem icon="sap-icon://message-error" tooltip="someTooltip" />

Either you need to extend the core: ListItem OR you can use a workaround for your problem using sap.m.CustomListItem and specify the icon tooltip.

View.xml

<List items="{/items}">
  <CustomListItem>
    <HBox>
      <core:Icon size="2rem" width="50px" tooltip="{tooltipInfo}" src="{icon}" />               
      <VBox>
        <Link text="{title}"/>
        <Label text="{type}"/>
      </VBox>
    </HBox>
  </CustomListItem>
</List>

Controller.js

var oModel = new sap.ui.model.json.JSONModel();
oModel.setData({
  "items": [
     { "tooltipInfo": "Group1", "icon": "sap-icon://hint", "type": "Monitor", "title": "Tiles: a modern UI design pattern for overview & navigation."},
     { "tooltipInfo": "Group2", "icon": "sap-icon://inbox", "number": "89", "title": "Approve Leave Requests", "info": "Overdue", "infoState": "Error" },
     { "tooltipInfo": "Group3", "icon": "sap-icon://email", "type": "Create", "title": "Create Leave Requests", "info": "28 Days Left", "infoState": "Success" },
     { "tooltipInfo": "Group4", "icon": "sap-icon://travel-expense-report", "number": "281", "numberUnit": "euro", "title": "Travel Reimbursement", "info": "1 day ago" },
     { "tooltipInfo": "Group5", "icon": "sap-icon://loan", "number": "2380", "numberUnit": "euro", "title": "My Salary", "info": "8 days ago" },
     { "tooltipInfo": "Group6", "icon": "sap-icon://lab", "number": "1", "numberUnit": "Invention", "title": "Test Lab Reports","info": "8 Days Ago" }]
});
this.getView().setModel(oModel);

Output
