Fragment中不能使用自定義帶參構(gòu)造函數(shù)

通過(guò)Fragment自定義的靜態(tài)方法將值從activity傳到fragment中，然后就想到這樣不是多次一舉嗎，為什么不直接寫(xiě)個(gè)帶參構(gòu)造函數(shù)將值傳過(guò)去呢？試了一下，發(fā)現(xiàn)Fragment有參構(gòu)造函數(shù)竟然報(bào)錯(cuò)，抱歉寫(xiě)了這么長(zhǎng)時(shí)間代碼對(duì)Fragment還不是很會(huì)用，笑哭，感覺(jué)任重道遠(yuǎn)啊...android中Fragment的構(gòu)造函數(shù)

String[] titles = {
                GlobalConfig.CATEGORY_NAME_APP,
                GlobalConfig.CATEGORY_NAME_ANDROID,
                GlobalConfig.CATEGORY_NAME_IOS,
                GlobalConfig.CATEGORY_NAME_FRONT_END,
                GlobalConfig.CATEGORY_NAME_RECOMMEND,
                GlobalConfig.CATEGORY_NAME_RESOURCE};

        CommonViewPagerAdapter infoPagerAdapter = new CommonViewPagerAdapter(getSupportFragmentManager(),titles);
        // App
        CategoryFragment appFragment = CategoryFragment.newInstance(titles[0]);
        // Android
        CategoryFragment androidFragment = CategoryFragment.newInstance(titles[1]);
        // iOS
        CategoryFragment iOSFragment = CategoryFragment.newInstance(titles[2]);
        // 前端
        CategoryFragment frontFragment = CategoryFragment.newInstance(titles[3]);
        // 瞎推薦
        CategoryFragment referenceFragment = CategoryFragment.newInstance(titles[4]);
        // 拓展資源s
        CategoryFragment resFragment = CategoryFragment.newInstance(titles[5]);

        infoPagerAdapter.addFragment(appFragment);
        infoPagerAdapter.addFragment(androidFragment);
        infoPagerAdapter.addFragment(iOSFragment);
        infoPagerAdapter.addFragment(frontFragment);
        infoPagerAdapter.addFragment(referenceFragment);
        infoPagerAdapter.addFragment(resFragment);

public static CategoryFragment newInstance(String mCategoryName) {
        CategoryFragment categoryFragment = new CategoryFragment();
        Bundle bundle = new Bundle();
        bundle.putString(CATEGORY_NAME, mCategoryName);
        categoryFragment.setArguments(bundle);
        return categoryFragment;
    }

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_blank, container, false);
        ButterKnife.bind(this, view);

        //取出傳過(guò)來(lái)的值
        Bundle bundle = getArguments();
        mTitle  = bundle.getString(ARG_TITLE);

        return view;
    }
