Public Methods

public UiSelector checkable (boolean val)

Set the search criteria to match widgets that are checkable. Typically, using this search criteria alone is not useful. You should also include additional criteria, such as text, content-description, or the class name for a widget. If no other search criteria is specified, and there is more than one matching widget, the first widget in the tree is selected.

Parameters
val Value to match
Returns
  • UiSelector with the specified search criteria
Since
  • Android API Level 18

public UiSelector checked (boolean val)

Set the search criteria to match widgets that are currently checked (usually for checkboxes). Typically, using this search criteria alone is not useful. You should also include additional criteria, such as text, content-description, or the class name for a widget. If no other search criteria is specified, and there is more than one matching widget, the first widget in the tree is selected.

Parameters
index Value to match
Returns
  • UiSelector with the specified search criteria

public UiSelector instance (int instance)

Set the search criteria to match the widget by its instance number. The instance value must be 0 or greater, where the first instance is 0.
