How are the two "trapezoids" that appear during text selection (in the emulator) called?
Where can I find more information about how to control them programmatically?
For further clarity, I am attaching a snapshot where you can see the left & right "text-selection trapezoids":
回答1:
We just call them cursor controllers, or handles.
回答2:
to be precise ..
In android terminology it is "SelectionModifierCursorController"
回答3:
It would appear based on the name of the images used to display these handles that they're called Text Select Handles, of which there's a
- Left Text Select Handle;
- Right Text Select Handle; and a
- Middle Text Select Handle (which is just the Left and Right images side-by-side)
The underlying code that manages these is in the three classes that derive from HandleView in android.widget.Editor:
InsertionHandleViewSelectionStartHandleViewSelectionEndHandleView

This is a shot in the dark--but maybe they're called carets in Webkit?
