Multine line label on settings

Question

I would like to crate a settings Activity with items with Title and subtitle.

I've checked a lot in documentation and even other posts here and people say it's not possible... android default settings page has a lot of it:

sorry for the picture in portuguese, but what is written there doesn't matter, the point is the settings page built on android has plenty of titile/subtitle items (and it happens in many other screens)

I would like to achieve it using android default Preference api. is that possible?

Yes it is possible. One fast solution is the following (that might be improvied and tuned according your needs):

public class SettingsActivity extends Activity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_settings);
        if (savedInstanceState == null) {
            getFragmentManager().beginTransaction()
                    .add(R.id.settings_fragment, new PrefsFragment()).commit();
        }
    }

    public static class PrefsFragment extends PreferenceFragment {

        public PrefsFragment(){}

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);

            // Load the preferences from an XML resource
            addPreferencesFromResource(R.xml.settings);
        }
    }
}

activity_settings.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <fragment
        android:id="@+id/settings_fragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:name="com.vb.myapplication.SettingsActivity$PrefsFragment" />
</LinearLayout>

settings.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory
        android:key="keyCategory"
        android:title="titleCategory">

        <CheckBoxPreference
            android:key="keyCheckPreference"
            android:title="titlePreference"
            android:summary="summaryPreference"
            android:defaultValue="false"/>
    </PreferenceCategory>
</PreferenceScreen>
