如何處理來自微調器的數組項目？

Question

我需要一個代碼來處理一個項目在陣列中的微調，讓我檢查 裏面.....

if(item == "item name"){ 
    do something 
} 

或

if(item.position == 1){ 
    do something 
}

你可以像這樣的代碼更改適配器

public class PlannedRideAdapter extends BaseAdapter {private void LayoutInflater mInflater;

private Context context; 
private RideData rideData = new RideData(); 
private List<RideData> ride_data; 

public PlannedRideAdapter(Context context, List<RideData> ridedata) { 
    this.context = context; 
    this.ride_data = ridedata; 

} 

@Override 
public int getCount() { 
    if (ride_data.size() > 0) { 

     return ride_data.size(); 
    } 
    return 1; 
} 

@Override 
public Object getItem(int arg0) { 
    return arg0; 
} 

@Override 
public long getItemId(int arg0) { 
    return arg0; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    ViewHolder viewholder; 

    if (convertView == null) { 
     LayoutInflater inflator = (LayoutInflater) context 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     convertView = inflator.inflate(R.layout.plannedride_km_list, null); 
     viewholder = new ViewHolder(); 
     convertView.setTag(viewholder); 

    } else { 
     viewholder = (ViewHolder) convertView.getTag(); 
    } 
    rideData = ride_data.get(position); 

    // init view 
    viewholder.imageView = (ImageView) convertView 
      .findViewById(R.id.imageView1); 
    viewholder.date = (TextView) convertView.findViewById(R.id.date_value); 
    viewholder.source = (CustomFontTextView) convertView 
      .findViewById(R.id.source_icon); 
    viewholder.time = (TextView) convertView.findViewById(R.id.time_value); 
    viewholder.destination = (CustomFontTextView) convertView 
      .findViewById(R.id.dest_icon); 
    viewholder.rideId = (CustomFontTextView) convertView 
      .findViewById(R.id.rideId); 
    viewholder.ride_id = (TextView) convertView 
      .findViewById(R.id.rideIdText); 
    viewholder.distance = (CustomFontTextView) convertView 
      .findViewById(R.id.distance); 
    viewholder.source_value = (TextView) convertView 
      .findViewById(R.id.source_value); 

    viewholder.ride_id_value = (TextView) convertView 
      .findViewById(R.id.rideId_value); 
    viewholder.distance_value = (TextView) convertView 
      .findViewById(R.id.distance_value); 
    // viewholder.ride_detail = (TextView) convertView 
    // .findViewById(R.id.textRideDetail); 
    // setview 
    viewholder.date.setText("" + rideData.getDate()); 
    viewholder.source.setText(context.getResources().getString(
      R.string.font_awesome_marker_icon)); 
    viewholder.source_value.setText("" + rideData.getSource()); 
    viewholder.time.setText("" + rideData.getTime()); 
    viewholder.rideId.setText(context.getResources().getString(
      R.string.font_awesome_bookingnumber_icon)); 
    viewholder.ride_id_value.setText("" + rideData.getRideId()); 
    if (rideData.getRideType().equalsIgnoreCase("k")) { 
     viewholder.distance.setVisibility(View.VISIBLE); 
     viewholder.distance_value.setVisibility(View.VISIBLE); 
     viewholder.imageView.setImageResource((R.drawable.one_way)); 

     viewholder.destination.setText(context.getResources().getString(
       R.string.font_awesome_radio_tick_icon)); 

     viewholder.distance.setText(context.getResources().getString(
       R.string.font_awesome_distance_icon)); 

     viewholder.distance_value.setText("" 
       + rideData.getKilometerRide().getDestination()); 

    } else { 
     viewholder.imageView.setImageResource((R.drawable.time)); 

     viewholder.destination.setText(context.getResources().getString(
       R.string.font_awesome_clock_icon)); 

     viewholder.distance.setVisibility(View.GONE); 
     viewholder.distance_value.setVisibility(View.GONE); 
     // viewholder.ride_detail.setVisibility(View.GONE); 
    } 
    return convertView; 
} 

public List<RideData> getRide_data() { 
    return ride_data; 
} 

public void setRide_data(List<RideData> ride_data) { 
    this.ride_data = ride_data; 
} 

public static class ViewHolder { 
    public CustomFontTextView source; 
    public CustomFontTextView destination; 
    public CustomFontTextView rideId; 
    public CustomFontTextView distance; 
    public CustomFontTextView total_time; 
    public TextView date, time, distance_value, source_value, 
      destination_value, time_value, ride_id_value, ride_id; 

    public ImageView imageView; 
} 

}

我出基於公里（rideType K）或每小時（rideType 1H）用相同的佈局列表。
