アダプターでgetFragmentManager（）を使用する方法

Question

アダプターでgetFragmentManager（）を使用する方法。どのようにアダプタでこのコードを使用しますか？ （私はSecondFragmentでこのコードを使用しています）。

Fragment frg = null; 
frg = getFragmentManager().findFragmentByTag("OneFragment"); 
final FragmentTransaction ft = getFragmentManager().beginTransaction(); 
ft.detach(frg); 
ft.attach(frg); 
ft.commit(); 

とアダプタでは、この方法では動作しません：

Fragment frg = null; 
frg = ((Activity) context).getFragmentManager().findFragmentByTag("OneFragment"); 
final FragmentTransaction ft = ((Activity) context).getFragmentManager().beginTransaction(); 
ft.detach(frg); 
ft.attach(frg); 
ft.commit(); 

とショーのエラー私に：私のアダプタで

Required: 
android.support.v4.app.Fragment 
Found: 
android.app.FragmentManage 

は（私がgetFragmentManager()を使用する必要があります私のアダプタ。）：

import android.content.Context; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentTransaction; 
import android.support.v7.widget.RecyclerView; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.view.animation.Animation; 
import android.view.animation.AnimationUtils; 
import android.widget.TextView; 

import me.bazaarche.Fragment.FilterFragment; 
import me.bazaarche.Fragment.HomeFragment; 
import me.bazaarche.app.R; 

public class CategorySub1Adapter extends RecyclerView.Adapter<CategorySub1Adapter.ViewHolder> { 

    private Context context; 
    private String[] categorySub1Name; 
    int categoryPosition; 
    int categorySub0Position; 
    FragmentManager fragmentManager; 

    public CategorySub1Adapter(Context context, FragmentManager fragmentManager, String[] categorySub1Name, int categoryPosition, int categorySub0Position) { 
     this.context = context; 
     this.categorySub1Name = categorySub1Name; 
     this.categoryPosition = categoryPosition; 
     this.categorySub0Position = categorySub0Position; 
     this.fragmentManager = fragmentManager; 
    } 

    class ViewHolder extends RecyclerView.ViewHolder { 
     View categorySub1Menu; 
     TextView categorySub1Name; 

     ViewHolder(View itemView) { 
      super(itemView); 
      categorySub1Menu = itemView.findViewById(R.id.category_sub0_menu); 
      categorySub1Name = itemView.findViewById(R.id.category_sub1_name); 
     } 
    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_category_sub1, parent, false); 
     return new ViewHolder(view); 
    } 

    @Override 
    public void onBindViewHolder(final ViewHolder holder, final int position) { 
     holder.categorySub1Name.setText(categorySub1Name[position]); 
     Animation animation = AnimationUtils.loadAnimation(context, R.anim.open_menu); 
     animation.setStartOffset(30 * position); 
     holder.itemView.startAnimation(animation); 

     HomeFragment.adAdapter.ClearList(); 
     HomeFragment.last_ad_id = 0; 
     FilterFragment.categoryPosition = categoryPosition; 
     FilterFragment.categorySub0Position = categorySub0Position; 
     FilterFragment.categorySub1Position = position; 
     HomeFragment.adAdapter.LoadMore(); 

     Fragment frg = null; 
     frg = fragmentManager.getFragmentManager().findFragmentByTag("OneFragment"); 
     final FragmentTransaction ft = fragmentManager.getFragmentManager().beginTransaction(); 
     ft.detach(frg); 
     ft.attach(frg); 
     ft.commit(); 
    } 

    @Override 
    public int getItemCount() { 
     return categorySub1Name.length; 
    } 
} 

私のアダプターにはgetFragmentManager()が必要です。

Answer 1

FragmentManagerを、ArrayAdapterコンストラクタの入力引数に追加します。あなたの活動またはSubActivityで

public class MyArrayAdapter extends ArrayAdapter { 
     List arr; 
     int resource; 
     Context context; 
     FragmentManager fragmentManager; 
     public MyArrayAdapter (Context context, int resource, List arr , FragmentManager fragmentManager) { 
      super(context, resource, arr); 
      this.arr=arr; 
      this.resource=resource; 
      this.context=context; 
      this.fragmentManager = fragmentManager; 
     } 
...... 
} 

もこのようFragmentManagerを得る：

this.getFragmentManager(); 

または

getActivity().getFragmentManager(); 

幸運！

変更は、これまであなたのインポート：

Fragment frg = null; 
frg = ((Activity) context).getSupportFragmentManager().findFragmentByTag("OneFragment"); 
final FragmentTransaction ft = ((Activity) context).getSupportFragmentManager().beginTransaction(); 
ft.detach(frg); 
ft.attach(frg); 
ft.commit();
