    public SearchEngineListPreference(Context context) {
        super(context);
        mContext = context;
    }

    public SearchEngineListPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
        mContext = context;
    }

    @SuppressWarnings("New API")
    public SearchEngineListPreference(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        mContext = context;
    }

    @SuppressWarnings("New API")
    public SearchEngineListPreference(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
        mContext = context;
    }

    @Override
    protected void onClick() {
        AlertDialog.Builder ab = new AlertDialog.Builder(mContext);
        ab.setCancelable(true);
        ab.setTitle(getTitle());
        String value = getValue();
        ab.setSingleChoiceItems(R.array.setting_entries_search_engine,
                findIndexOfValue(value),
                (dialog, index) -> {
                    CharSequence[] entryValues = getEntryValues();
                    if (callChangeListener(entryValues[index].toString())){
                        setValueIndex(index);
                    }
                    dialog.dismiss();
                }).setNeutralButton(mContext.getString(R.string.dialog_button_custom),
                (dialog, whichButton) -> {
                    dialog.dismiss();
                    showEditDialog();
                }).setNegativeButton(mContext.getString(R.string.dialog_button_negative),
                (dialog, whichButton) -> {
                    dialog.dismiss();
                });
