Remarks
Finds a view that was identified by the android:id XML attribute that was processed in android.app.Activity#onCreate.
This will implicitly call #getDecorView with all of the associated side-effects.
<strong>Note:</strong> In most cases -- depending on compiler support -- the resulting view is automatically cast to the target class type. If the target class type is unconstrained, an explicit cast may be necessary.
