ラグのArrayListをフィルタリングし、RecyclerView

用のアダプタを設定するときにちょっと私はRecyclerViewでリストをフィルタリングSwitchCompat、ショーで私のArrayListをフィルタ処理しようとしていると私はこのコードを使用しています：ラグのArrayListをフィルタリングし、RecyclerView

cancelled = (SwitchCompat) inc.findViewById(R.id.cancelledSwitch); 
    cancelledByAdmin = (SwitchCompat) inc.findViewById(R.id.cancelledByAdminSwitch); 
    reserved = (SwitchCompat) inc.findViewById(R.id.reservedSwitch);

    deprecated.setOnCheckedChangeListener(filterswitch);

    pending.setOnCheckedChangeListener(filterswitch); 
    cancelledByAdmin.setOnCheckedChangeListener(filterswitch); 
    reserved.setOnCheckedChangeListener(filterswitch); 

    CompoundButton.OnCheckedChangeListener filterswitch = new CompoundButton.OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(CompoundButton compoundButton, boolean b) { 
     filter(); 
    } 
}; 

public void filter() { 
    ArrayList<ReservedTimesModel> filtered = new ArrayList<>();

}

私のarrayListのサイズは18ですが、SwitchCompatのいずれかをクリックすると約1秒遅れます。なぜこうなった？

あなたのアプリをプロファイルしようとしましたか？ [this]（https://developer.android.com/studio/profile/traceview.html） – pskink

を参照してください。ボトルネックは 'onBindViewHolder'の中に' 'Html.fromHtml''があり、代わりに' Spannable＃setSpan'を使用しました。あなたのアプリをプロファイルしますか？上に投稿したリンクを見たことがありますか？ – pskink

ええ、それを確認しましたが、@ pskink –

データが変更されるたびにsetAdapterする必要はありません。あなたがして（あなたの活動onCreate()に）一度あなたのデータの変更は、データが再びアダプタと呼び出すように設定するたびにアダプタを作成myAdapter.notifyDataSetChanged();

public void setList(ArrayList<ReservedTimesModel> arrayList) 
    { 
     this.arrayList = arrayList; 
    }

が、その後ReservedTimesAdapterオブジェクトを定義し、追加ReservedTimesAdapterクラスにこのメソッドを追加このclass.likeあなたの活動onCreate()からsetAdapterコード：

ReservedTimesAdapter myAdapter= new ReservedTimesAdapter(filtered, ReservedTimesActivity.this); 

recyclerView.setAdapter(myAdapter);

とを変更の方法は次のとおりです。

public void filter() { 
    ArrayList<ReservedTimesModel> filtered = new ArrayList<>(); 
    for (ReservedTimesModel reservedTimesModel : arrayList) { 
    switch (reservedTimesModel.res_status) { 
     case "CanceledByAdmin": 
      if (cancelledByAdmin.isChecked()) { 
       filtered.add(reservedTimesModel); 
      } 
      break; 
     case "Canceled": 
      if (cancelled.isChecked()) { 
       filtered.add(reservedTimesModel); 
      } 
      break; 
     case "Pending": 
      if (pending.isChecked()) { 
       filtered.add(reservedTimesModel); 
      } 
      break; 
     case "Deprecated": 
      if (pending.isChecked()) { 
       filtered.add(reservedTimesModel); 
      } 
      break; 
     default: 
      if (reserved.isChecked()) { 
       filtered.add(reservedTimesModel); 
      } 
     } 
    } 
    myAdapter.setList(filtered); 
    myAdapter.notifyDataSetChanged(); 
}

はい、私は' new ReservedTimesAdapter（） 'と' recyclerView.setAdapter（） 'の両方が時間のかかる作業であると信じています –

投稿コードどのようにデータを設定できますか？私が試したすべてが@AlexCohnを働かせなかったので私のアダプター –

それは遅れを減らしてくれてありがとう –
