Passing a reference of an object to activity

Question

I have a reference to an anonymous class object that I want to pass to an activity. It is a kind of reference to a callback fn which gets called based on an action on activity i.e. click of button. But, I dont know a way to do so as activities can not be instantiated directly (done only through startActivity) and using intents will pass my object by value not by reference. So, I need tips on a good solution. I want to avoid statics.

Answer 1

Short Answer: No You cannot pass objects as references to activities.

Answer 2

Try this

CustomListing currentListing = new CustomListing();
Intent i = new Intent();
Bundle b = new Bundle();
b.putParcelable(Constants.CUSTOM_LISTING, currentListing);
i.putExtras(b);
i.setClass(this, SearchDetailsActivity.class);
startActivity(i);

Afterwards to call

Bundle b = this.getIntent().getExtras();
if (b != null)
 mCurrentListing = b.getParcelable(Constants.CUSTOM_LISTING);

Answer 3

Here is the answer :
Create a public static method in the Activity to which you want to pass the reference of an object.

public static void openActivity(Activity activity, Class object){
        YourNextActivity.object = object;
        Intent intent = new Intent(activity, YourNextActivity.class);
        activity.startActivity(intent);
}

Call this method from current Activity :

YourNextActivity.openActivity(this, classObject);
