Class ViewShorthand
java.lang.Object
positron.harness.ViewShorthand
public class ViewShorthand
- extends Object
Use dot notation to navigate getters and array/child indexing.
All access is done through method reflection; no public properties are
examined.
Getter getXxx may be specified as ".getXxx" or ".xxx". Note that getters
that don't start with "get" just use their names: for String.length() use
"length".
Arrays and ViewGroups may be indexed. To index a ViewGroup, getChildAt is
called. Indexes are specified with a dot: ".listView.2" on a ListActivity
would yield getListView().getChildAt(2).
Use a # prefix to do a child view lookup by id. This is only legal when the
current receiving object is an Activity (though this could be extended; make
some noise or patch if you really want it.) The ids themselves should be the
id strings just as they appear in your layout xml.
So "#my_text_view.text" would findViewById(R.id.my_text_view).getText().
Clearly all this reflection bypasses type checking; you will get
ClassCastExceptions, etc, if you are not careful.
