Passing a Bundle on startActivity()?

Question

What\'s the correct way to pass a bundle to the activity that is being launched from the current one? Shared properties?

Answer 1

You have a few options:

1) Use the Bundle from the Intent:

Intent mIntent = new Intent(this, Example.class);
Bundle extras = mIntent.getExtras();
extras.putString(key, value);  

2) Create a new Bundle

Intent mIntent = new Intent(this, Example.class);
Bundle mBundle = new Bundle();
mBundle.putString(key, value);
mIntent.putExtras(mBundle);

3) Use the putExtra() shortcut method of the Intent

Intent mIntent = new Intent(this, Example.class);
mIntent.putExtra(key, value);

Then, in the launched Activity, you would read them via:

String value = getIntent().getExtras().getString(key)

NOTE: Bundles have "get" and "put" methods for all the primitive types, Parcelables, and Serializables. I just used Strings for demonstrational purposes.
