Android - 複数のオブジェクトを持つRecyclerview/arraylist？

Question

私は、私のarraylistによってフィードされた私のrecyclerviewで複数のオブジェクトを実装する方法を知っています。特に多くのコードを変更したいとは思いません。ここで私は、現在持っているものです： Viewholder：ArrayListのによって供給

public class MyViewHolder extends RecyclerView.ViewHolder{ 

TextView exercise; 
TextView percent; 
TextView reps; 
TextView weight; 
CheckBox check1; 
CardView mCardView; 
ItemClickListener itemClickListener; 

public MyViewHolder(View itemView) { 
    super(itemView); 

    exercise= (TextView) itemView.findViewById(R.id.txtExercise); 
    percent= (TextView) itemView.findViewById(R.id.txtPercentage); 
    reps= (TextView) itemView.findViewById(R.id.txtReps); 
    weight= (TextView) itemView.findViewById(R.id.txtWeight); 
    check1 = (CheckBox) itemView.findViewById(R.id.check1); 
    mCardView = (CardView) itemView.findViewById(R.id.card_view); 

} 
} 

のRv：

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    SharedPreferences pref = this.getActivity().getSharedPreferences("MyPref", 0); 
    prefs = getContext().getSharedPreferences("checkState", Context.MODE_PRIVATE); 

//RECYCLERVIEW 
    final RecyclerView rv = (RecyclerView) view.findViewById(R.id.mRecyclerFri); 
    rv.setLayoutManager(new LinearLayoutManager(this.getActivity())); 

    rv.setAdapter(new MyRecyclerAdapter(this.getActivity(), getFriWorkout(), 3)); 

private ArrayList<Workout> getFriWorkout() { 
    ArrayList<Workout> workout = new ArrayList<>(); 
    switch (workout3) { 
     case "w29": { 
      Workout workouts = new Workout(getActivity().getString(R.string.benchpress), "50", "5", bench50, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "60", "5", bench60, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "70", "4", bench70, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "75", "3", bench75, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "75", "3", bench75, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "80", "2", bench80, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "80", "2", bench80, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "75", "3", bench75, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "75", "3", bench75, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "70", "4", bench70, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "60", "6", bench60, false); 
      workout.add(workouts); 
      workouts = new Workout(getActivity().getString(R.string.benchpress), "50", "8", bench50, false); 
      workout.add(workouts); 

      workouts = new Workout(getActivity().getString(R.string.db_fly), "5 Sets", "10 Reps", "", false); 
      workout.add(workouts); 

      workouts = new Workout(getActivity().getString(R.string.squat), "50", "5", squat50, false); 
      workout.add(workouts); 

RecyclerViewアダプタ：

public class MyRecyclerAdapter extends RecyclerView.Adapter<MyViewHolder> { 

Context mContext; 
ArrayList<Workout> workout; 
SharedPreferences prefs; 
int firstSecondOrThird; 
int colorResId = R.color.defaultcard; 

public MyRecyclerAdapter(Context context, ArrayList<Workout> workout, int thePosition) { 
    mContext = context; 
    this.workout = workout; 
    this.firstSecondOrThird = thePosition; 
} 
// INITIALIZE HOLDER 
@Override 
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.workout_item, null); 
    MyViewHolder holder = new MyViewHolder(view); 

    return holder; 
} 

private SparseBooleanArray mCheckedItems = new SparseBooleanArray(); 

//BIND DATA TO VIEWS 
@Override 
public void onBindViewHolder(final MyViewHolder holder, final int position) { 
    holder.exercise.setText(workout.get(position).getExercise()); 
    holder.percent.setText(workout.get(position).getPercent()); 
    holder.reps.setText(workout.get(position).getReps()); 
    holder.weight.setText(workout.get(position).getWeight()); 
    holder.check1.setOnCheckedChangeListener(null); 

    holder.check1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
      prefs.edit().putBoolean(firstSecondOrThird + "checkState" + position, isChecked).apply(); 
     } 
    }); 
    holder.check1.setChecked(prefs.getBoolean(firstSecondOrThird+"checkState"+position, false)); 
} 


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

@Override 
public long getItemId(int position) { 
    return super.getItemId(position); 
} 

は基本的に私が何をしたいのか第2のレイアウトを追加することです5つのチェックボックスしかない特定のエクササイズの下で膨らませるために。私はいくつかの答えを読んだが、私がアンドロイドの新しい人であるので、それらをかなり混乱させることが分かった。多くのコードを変更しなくても簡単な方法です助けてくれてありがとう！

あなたは正しい軌道に乗っています。 MyRecyclerAdapter内では、onCreateViewHolder（）メソッドをオーバーライドしてカスタムレイアウトを拡張し、それをViewHolderに渡す必要があります。ここで私がいつか働いてくれたプロジェクトへのリンクがあります。あなたがこれをどうやってできるかを示しています（https://github.com/ucsunil/Lockers/blob/master/app/src/main/java/com/ebay/lockers/adapters/HomePageItemsAdapter.java）。私は、ArrayListを使ってViewHolderにデータを供給しました。

個々の行は、onBindViewHolder（）メソッドを使用してViewHolderにバインドする必要があります。
