Public methods
onBound
void onBound (T binding)
Called after values have been reevaluated in executePendingBindings()
. This is only called if all listeners have
returned true from onPreBind(ViewDataBinding)
.
The default implementation does nothing.
Parameters | |
---|---|
binding |
T : The ViewDataBinding that is reevaluating its bound values.
|
onCanceled
void onCanceled (T binding)
Called after all callbacks have completed onPreBind(ViewDataBinding)
when
one or more of the calls has returned false
.
The default implementation does nothing.
Parameters | |
---|---|
binding |
T : The ViewDataBinding that is reevaluating its bound values.
|
onPreBind
boolean onPreBind (T binding)
Called when values in a ViewDataBinding should be reevaluated. This does not mean that values will actually change, but only that something in the data model that affects the bindings has been perturbed.
Return true to allow the reevaluation to happen or false if the reevaluation
should be stopped. If false is returned, it is the responsibility of the
OnRebindListener implementer to explicitly call executePendingBindings()
.
The default implementation only returns true
.
Parameters | |
---|---|
binding |
T : The ViewDataBinding that is reevaluating its bound values. |
Returns | |
---|---|
boolean |
true to indicate that the reevaluation should continue or false to halt evaluation. |
