How to up navigate from fragment activity?

Question

Hi I am having trouble while going back to parent activity from fragment activity. I want back arrow at top left corner inside the action bar.

I am able to show it in action bar activity using this code

getSupportActionBar().setDisplayShowHomeEnabled(true);

But I am not able to do it in tabbed activity's fragment.

((AppCompatActivity)getActivity()).getSupportActionBar().setDisplayShowHomeEnabled(true);

Please Help me!!

Add this inside onCreate() of your tabbed activity,

toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);

And for navigating back, you need to override following method in your tabbed activity.

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == android.R.id.home) {
            onBackPressed();
        }
        return super.onOptionsItemSelected(item);
    }

Happy coding.
