java - How to call the constructor of an activity's parent class -



java - How to call the constructor of an activity's parent class -

this question off-shoot of difficult problem working on. 1 of suggestion phone call constructor of parent activity. know how might that? mean, have activity called dogactivity , have parentactivity such dogactivity extends parentactivity. utilize oncreate communicate parent activities in super.oncreate(savedinstancestate) instance. @ loss of how phone call constructor of parent activity. need pass info through constructor. how know android phone call same instance of parent when needs deal callbacks , lifecycle methods? please see original question reference if need to.

public class dogactivity extends parentactivity { public dogactivity() { super("something", new someobject()); // calling super's constructor } }

however on android rare you'd have occasion need phone call parents constructor. have doing wrong.

java android android-activity
