删除父视图以设置自定义布局视图

Question

i'm trying to add a custom layout to my settings app for personalization options with a clickable header image that launches a web url but the main preference layout is already set by my settings activiy, how can i remove the parent view so my custom layout can be inflated?

public class DEMENTED extends SettingsPreferenceFragment implements
        Preference.OnPreferenceChangeListener {
    private static final String TAG = "DEMENTED";
    private static final String KEY_DEMENTED_GITHUB = "https://github.com/cphelps76";
    private static final String KEY_DEMENTED_HEADER = "logo";
    private static final String KEY_GESTURE_SETTINGS = "prefs_gesture";

    Preference mlogo;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.demented_interface, container);
    }

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

        addPreferencesFromResource(R.xml.demented_interface_settings);

        mlogo = findPreference(KEY_DEMENTED_HEADER);

        Utils.updatePreferenceToSpecificActivityFromMetaDataOrRemove(getActivity(),
            getPreferenceScreen(), KEY_GESTURE_SETTINGS);
    }

    @Override
    protected int getMetricsCategory() {
        return MetricsLogger.DEMENTED_INTERFACE;
    }

    @Override
    public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference) {
        if (preference == mlogo) {
            launchUrl(KEY_DEMENTED_GITHUB);
            return true;
        }
        return super.onPreferenceTreeClick(preferenceScreen, preference);
    }

    public boolean onPreferenceChange(Preference preference, Object objValue) {
        final String key = preference.getKey();
        return true;
    }

    private void launchUrl(String url) {
        Uri uriUrl = Uri.parse(url);
        Intent whatever = new Intent(Intent.ACTION_VIEW, uriUrl);
        getActivity().startActivity(whatever);
    }
}

I solved my own problem by inflating my bas preference view in OnCreateView and finding the imageview id and then making my image clickable and setting an onclick listener

public class DEMENTED extends SettingsPreferenceFragment implements
        Preference.OnPreferenceChangeListener, View.OnClickListener {

    private static final String TAG = "DEMENTED";
    private static final String KEY_DEMENTED_GITHUB = "https://github.com/cphelps76";
    private static final String KEY_GESTURE_SETTINGS = "prefs_gesture";
    private static final String KEY_HARDWARE_KEYS = "prefs_buttons";

    private ImageView mLogoView;

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

        addPreferencesFromResource(R.xml.demented_interface_settings);
        removePreferences();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.preference_list_fragment, parent, false);
        mLogoView = (ImageView)rootView.findViewById(R.id.logo);
        updateView();
        return rootView;
    }

    private boolean hasButtons() {
        return getResources().getInteger(
                com.android.internal.R.integer.config_deviceHardwareKeys) != 0;
    }

    private void removePreference(Preference preference) {
        getPreferenceScreen().removePreference(preference);
    }

    private void removePreferences() {
        Utils.updatePreferenceToSpecificActivityFromMetaDataOrRemove(getActivity(),
        getPreferenceScreen(), KEY_GESTURE_SETTINGS);
        if (!hasButtons()) {
            removePreference(KEY_HARDWARE_KEYS);
        }
    }

    private void updateView() {
        if (mLogoView != null) {
            mLogoView.setClickable(true);
            mLogoView.setOnClickListener(this);
        }
    }

    @Override
    public void onClick(View v) {
        if (v == mLogoView) {
            v.performHapticFeedback(HapticFeedbackConstants.VIRTUAL_KEY);
            launchUrl(KEY_DEMENTED_GITHUB);
        }
    }

    @Override
    protected int getMetricsCategory() {
        return MetricsLogger.DEMENTED_INTERFACE;
    }

    public boolean onPreferenceChange(Preference preference, Object objValue) {
        final String key = preference.getKey();
        return true;
    }

    private void launchUrl(String url) {
        Uri uriUrl = Uri.parse(url);
        Intent demented = new Intent(Intent.ACTION_VIEW, uriUrl);
        getActivity().startActivity(demented);
    }
}
