SAPUI5 get current context in detail view

You can use getPath() of a bindingContext to see what object is currently displayed:

this.getView().getBindingContext().getPath();

You could do something like this:

var bindingContext = this.getView().getBindingContext();
var path = bindingContext.getPath();
var object = bindingContext.getModel().getProperty(path);

If you only want a certain property of your displayed object you can do something like this:

var property = bindingContext.getProperty("<nameOfProperty>");

which returns a property of an object at specific context.

Update:

You can simply call getObject() of a bindingContext which returns the object in the model the current context points to:

var object = bindingContext.getObject();

See the documentation of Context for more information.
