Show up-Button in actionBar in subscreen preferences

Question

I\'ve implemented my preferences like shown in the official guidelines.

I have a PreferenceActivity which creates the PreferenceFragment like this:

Answer 1

To enable the up action do the following:

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayUseLogoEnabled(true);

this will give you the icon.

then add

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        // Respond to the action bar's Up/Home button
        case android.R.id.home:
            finish();
            return true;
    }
    return super.onOptionsItemSelected(item);
}

you can alter this to go where you need to. As another option you can use the navigateUpTo(Intent intent) and the onSupportNavigateUpTo(Intent intent) methods and specify the intent you want to return to.
