RecyclerViewで異種レイアウトが正しく表示されない

Question

私は、メンバーとしてCursorAdapterを持つRecyclerView内で2つのビューを使用したい天気予報アプリケーションを開発しています。私は今日の天気と他の日の天気を表示するための他のビューを表示するために1つのビューを使用したい。私のRecyclerViewは完全に動作していますが、私は2つのレイアウトを表示していますが、正しくレイアウトしていません。今日の天気に使用したい天気予報と2番目の最後の日はリストにあります。

以下は私のRecyclerViewアダプタのコードです：

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

    private static int VIEW_TYPE_TODAY = 0; 
    private static int VIEW_TYPE_FUTURE_DAY = 1; 
    private static final int VIEW_TYPE_COUNT = 2; 
    public CursorAdapter mCursorAdapter; 
    private Context mContext; 

    // Provide a reference to the views for each data item 
    // Complex data items may need more than one view per item, and 
    // you provide access to all the views for a data item in a view holder 
    public class ViewHolder extends RecyclerView.ViewHolder { 
     // each data item is just a string in this case 
     TextView date,weather,min,max; 
     ImageView icon; 
     public ViewHolder(View itemView) { 
      super(itemView); 
      date =(TextView) itemView.findViewById(R.id.list_item_date_textview); 
      weather = (TextView) itemView.findViewById(R.id.list_item_forecast_textview); 
      min = (TextView) itemView.findViewById(R.id.list_item_low_textview); 
      max = (TextView) itemView.findViewById(R.id.list_item_high_textview); 
      icon = (ImageView) itemView.findViewById(R.id.list_item_icon); 
     } 
    } 



    // Provide a suitable constructor (depends on the kind of dataset) 
    public WeatherAdapter(Context context, Cursor c,int flags) { 
     mContext = context; 
     mCursorAdapter = new CursorAdapter(mContext,c,flags) { 
      @Override 
      public View newView(Context context, Cursor cursor, ViewGroup parent) { 
       int viewType = getItemViewType(cursor.getPosition()); 
       int layoutId = -1; 
       if(viewType==VIEW_TYPE_TODAY) 
        layoutId = R.layout.list_item_forecast_today; 
       else if(viewType==VIEW_TYPE_FUTURE_DAY) 
        layoutId = R.layout.list_item_forecast; 
       View view = LayoutInflater.from(context).inflate(layoutId, parent, false); 
       return view; 
      } 

      @Override 
      public void bindView(View itemView, Context context, final Cursor cursor) { 
       // our view is pretty simple here --- just a text view 
       // we'll keep the UI functional with a simple (and slow!) binding. 

       TextView date,weather,min,max; 
       ImageView icon; 

       date =(TextView) itemView.findViewById(R.id.list_item_date_textview); 
       weather = (TextView) itemView.findViewById(R.id.list_item_forecast_textview); 
       min = (TextView) itemView.findViewById(R.id.list_item_low_textview); 
       max = (TextView) itemView.findViewById(R.id.list_item_high_textview); 
       icon = (ImageView) itemView.findViewById(R.id.list_item_icon); 

       int weatherId = cursor.getInt(ForecastFragment.COL_WEATHER_ID); 
       icon.setImageResource(R.drawable.ic_launcher); 
       long dateId = cursor.getLong(ForecastFragment.COL_WEATHER_DATE); 
       date.setText(Utility.getDayName(mContext,dateId)); 
       String weatherDesc = cursor.getString(ForecastFragment.COL_WEATHER_DESC); 
       weather.setText(weatherDesc); 
       boolean isMetric = Utility.isMetric(mContext); 
       double high = cursor.getDouble(ForecastFragment.COL_WEATHER_MAX_TEMP); 
       max.setText(Utility.formatTemperature(high, isMetric) + "/"); 
       double low = cursor.getDouble(ForecastFragment.COL_WEATHER_MIN_TEMP); 
       min.setText(Utility.formatTemperature(low, isMetric)); 
      } 

      @Override 
      public int getViewTypeCount() { 
       return VIEW_TYPE_COUNT; 
      } 

      @Override 
      public int getItemViewType(int position) { 
       Log.e("getItemViewType: ",""+position); 
       if(position == VIEW_TYPE_TODAY) 
        return VIEW_TYPE_TODAY; 
       else 
        return VIEW_TYPE_FUTURE_DAY; 
      } 
     }; 
    } 

    // Create new views (invoked by the layout manager) 
    @Override 
    public WeatherAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, 
                int viewType) { 
     // create a new view 
     View v = mCursorAdapter.newView(mContext, mCursorAdapter.getCursor(), parent); 
     return new ViewHolder(v); 
    } 

    // Replace the contents of a view (invoked by the layout manager) 
    @Override 
    public void onBindViewHolder(final ViewHolder holder, final int position) { 
     mCursorAdapter.getCursor().moveToPosition(position); 
     mCursorAdapter.bindView(holder.itemView, mContext, mCursorAdapter.getCursor()); 
     Cursor cursor = mCursorAdapter.getCursor(); 
     cursor.moveToPosition(position); 

     holder.itemView.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Cursor cursor = mCursorAdapter.getCursor(); 
       cursor.moveToPosition(position); 
       if (!cursor.isClosed()) { 
        String locationSetting = Utility.getPreferredLocation(mContext); 
        Intent intent = new Intent(mContext.getApplicationContext(), DetailActivity.class) 
          .setData(WeatherContract.WeatherEntry.buildWeatherLocationWithDate(
            locationSetting, cursor.getLong(ForecastFragment.COL_WEATHER_DATE) 
          )); 
        mContext.startActivity(intent); 
       } 
      } 
     }); 
    } 

    // Return the size of your dataset (invoked by the layout manager) 
    @Override 
    public int getItemCount() { 
     return mCursorAdapter.getCount(); 
    } 


} 

私はあなたがWeatherAdapter中）（getItemViewTypeをも持っている必要があり、高度な

Answer 1

の私implementation.Thanksで間違ったかを理解することはできませんよ。あなたはそれをCursorAdapterに持っています。

@Override 
int getItemViewType (int position) { 
    return mCursorAdapter.getItemViewType(position); 
}
