Disabling Android Up Navigation Depending on the Value of an Intent Extra

Question

I am navigating to Android activity A from different activities. Depending on which activity, A is called from, I may or may not want to provide up-navigation on A.

intent.putExtra("ShouldProvideUpNav", true); // or false

I read this intent extra in A's onCreate(Bundle savedInstanceState)

shouldProvideUpNav = intent.getBooleanExtra("ShouldProvideUpNav", false);

I am not sure where I should use this boolean to disable the up navigation if the value is false. Any help will be appreciated.

Answer 1

You can do this from within your onCreate() method. Depending on what you would like enabled you can set both of these attributes accordingly there.

actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setHomeButtonEnabled(false);

of which you can get your ActionBar through getActionBar() if desired.
