静态类中的getFragmentManager方法如何使用？[关闭]

Question

结束了。 这个问题需要 调试细节. 目前不接受回答。

想改进这个问题？ 请更新问题，使之成为 题外话 为Stack Overflow。

已关闭 上月.

改进这个问题

我之前看了这个问题的答案，但我不明白如何解决我的问题。

 FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        AkisFragment NAME = new AkisFragment();
        fragmentTransaction.replace(R.id.fragment_tutucu, NAME);
        fragmentTransaction.commit();

注：我的类必须是静态的.getFragmentManager()方法在静态类中是如何工作的？getFragmentManager()方法是Fragment类的一个方法。

FragmentManager类的对象是通过getFragmentManager()来创建和同步的.我不明白为什么不希望静态类的getFragmentManager()方法工作。

你想看我类中的所有代码吗？

已发出无关代码。

我的java代码。

public static class KelimelerAdapterx extends RecyclerView.Adapter { / boolean f; private Context mContext; public List kelimelerListe; public ArrayList teststringsx = new ArrayList<>（）。

    String svvs;
    Fragment fragment;
    private int mScrollState = AbsListView.OnScrollListener.SCROLL_STATE_IDLE;
    public RecyclerView rv;
    testc fd = new testc();


    public KelimelerAdapterx(Context mContext, List<Kelimeler> kelimelerListe) {
        this.mContext = mContext;
        this.kelimelerListe = kelimelerListe;
    }

    @Override
    public KelimelerAdapterx.CardTasarimTutucu onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_tasarim,parent,false);
      //  Log.e("scrolldurumburcussv", String.valueOf(scrolldurum));

        return new KelimelerAdapterx.CardTasarimTutucu(view);
    }




    @Override
    public void onBindViewHolder(final KelimelerAdapterx.CardTasarimTutucu holder, int position) {
        final Kelimeler kelime = kelimelerListe.get(position);
        teststring fe = new teststring(position);
        Log.e("armutlaaarrsss", String.valueOf(fe.getId()));
        holder.textViewIngilizce.setText(String.valueOf(kelime.getId()));
        holder.textViewTurkce.setText(kelime.getLikebtn());
        holder.ad.setText(kelime.getAd()); holder.ad.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    Log.e("t4rryert", "dddddgsg");
    Profil profil = new Profil();
    profil.idvalue(kelime.getId());

    FragmentManager fragmentManager = getFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    AkisFragment NAME = new AkisFragment();
    fragmentTransaction.replace(R.id.fragment_tutucu, NAME);
    fragmentTransaction.commit();


    } });


        testc f = new testc();
        Log.e("armutelma", String.valueOf(f.elma));

    }

    @Override
    public int getItemCount() {
        return kelimelerListe.size();

    }

    public static class CardTasarimTutucu extends RecyclerView.ViewHolder{
        public TextView textViewIngilizce;
        public TextView textViewTurkce;
        public CardView kelime_card;
        SimpleVideoView videoView;
        RecyclerView.RecyclerListener recyclerListener;
        View view;
        ScrollView scrollView;
        private RecyclerView rvx;
        boolean fddd;
        Button btn,btntwo,btnthree,start_button,ad;
        AkisFragment fff ; boolean muz = true;
        private boolean playWhenReady = true;
        private int currentWindow = 0;
        private long playbackPosition = 0;
        int i = 0;

        public CardTasarimTutucu(View itemView) {
            super(itemView);
            textViewIngilizce = itemView.findViewById(R.id.textViewIngilizce);
            textViewTurkce = itemView.findViewById(R.id.textViewTurkce);
            ad = itemView.findViewById(R.id.ad);
            kelime_card = itemView.findViewById(R.id.kelime_card);
            videoView = itemView.findViewById(R.id.videoview);
            scrollView = itemView.findViewById(R.id.scrollView);
            btn = itemView.findViewById(R.id.btn);
            btntwo = itemView.findViewById(R.id.btntwo);
            btnthree = itemView.findViewById(R.id.btnthree);

        }
        public boolean veripost(boolean one){
            Log.e("renkssss", String.valueOf(one));
            Log.e("renkf", String.valueOf(fddd));

            return  one;

        }


    }

下面的代码在静态类中无法使用。

FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        AkisFragment NAME = new AkisFragment();
        fragmentTransaction.replace(R.id.fragment_tutucu, NAME);
        fragmentTransaction.commit();

当我不再把我的类做成静态的时候，我就解决了这个问题。
