MultiChoiceModeListener android source

I am trying to find the code of MultiChoiceModeListener interface from the Android source. But all i could find is a skeleton : http://androidxref.com/4.4.2_r2/xref/frameworks/base/core/java/android/widget/AbsListView.java#6301

It just says that it extends the ActionMode.CallBack interface, which is also just a skeleton : http://androidxref.com/4.4.2_r2/xref/frameworks/base/core/java/android/view/ActionMode.java#229

Where exactly is the code that defines the behaviour of MultiChoiceModeListner? For example, where is the code that calls the startActionMode() when using the MultiChoiceModeListner?

Solution

  • MultiChoiceModeListener is an interface, so you will not find any code defining its behavior just because interface only defines methods and not their implementations(like abstract class may do).

    Basicly MultiChoiceModeWrapper class is implementing the MultiChoiceModeListener and its located in AbsListView.java.

    AbsListView holds MultiChoiceModeWrapper field mMultiChoiceModeCallback and uses it upon different scenarios.
