How to Create an Element Selector

A UiElementSelector usually contains CssAttributes by which we will select a UiElement from the active screen.

Create UiElementSelector and add selector Attributes

  1. Create a UiElementSelector.
  2. Dump the XML so you can see all Elements and their CssAttributes. For more information you can check How to dump XML.
  3. Add CssAttributes to the UiElementSelector by which the Element will be selected.
  • Note that if there are two or more UiElement objects that can be selected by the UiElementSelector and we only need one, an error occurs, so you have to be very specific about the attributes values.
  • You can add more than one attribute to the Selector.

Example code for creating a UiElementSelector:

UiElementSelector elementSelector = new UiElementSelector();
elementSelector.addSelectionAttribute(CssAttribute.CLASS_NAME, "android.widget.TextView");
elementSelector.addSelectionAttribute(CssAttribute.TEXT, "Browser");

The created Selector will select the browser icon on the home screen of the Device if there is one.

We can also create a UiElementSelector directly using the constructor with a HashMap with added CSS attributes as Strings to it. Example code:

Map<String, String> nodeAttributeMap = new HashMap<>();
nodeAttributeMap.put("bounds", "[10,15][200,100]");
nodeAttributeMap.put("index", "5");
nodeAttributeMap.put("content-desc", "my-content");
nodeAttributeMap.put("text", "my-text");t
nodeAttributeMap.put("long-clickable", "true");
nodeAttributeMap.put("password", "false");
uiElementSelector = new UiElementSelector(nodeAttributeMap);

Attributes with which you can Select an Element

You can select an Element with the attributes in NoteDetails in the Dump XML. Every Element has these attributes and can be selected by one or more of them. Also they contain fields like Enabled, Checked, Focused and others. With them we can check if the interactions are successful or not. For more information you can check How to dump XML.
