只有最後一個元素在listView中多次顯示

Question

我有這種方法將元素添加到GetterSetter類中，並將它們添加到listList中並添加到listView中。事情是在listView中，它只是多次顯示數組中的最後一項。
我不明白爲什麼？任何解決方案

這裏是我的代碼：

protected void onPostExecute(String str) { 

    myArrayList = new ArrayList<GetterSetter>(); 
    addValues = new GetterSetter(); 
    String rating="-NA-"; 
    try { 

     JSONObject root = new JSONObject(str); 
     JSONArray results = root.getJSONArray("results"); 
     for (int i = 0; i < results.length(); i++) { 
      JSONObject arrayItems = results.getJSONObject(i); 
      JSONObject geometry = arrayItems.getJSONObject("geometry"); 
      JSONObject location = geometry.getJSONObject("location"); 

      if(!arrayItems.isNull("rating")){ 
       rating = arrayItems.getString("rating"); 
      } 

      addValues.setLat(location.getString("lat")); 
      addValues.setLon(location.getString("lng")); 
      addValues.setName(arrayItems.getString("name").toString()); 
      addValues.setRating(rating); 
      addValues.setVicinity(arrayItems.getString("vicinity").toString()); 

      Log.d("Before", myArrayList.toString()); 

      myArrayList.add(addValues); 

     } 
    } catch (Exception e) { 

    } 
    System.out 
      .println("############################################################################"); 
    Log.d("After:", myArrayList.toString()); 
    nodata = (TextView) findViewById(R.id.nodata); 
    nodata.setVisibility(View.GONE); 
    adapter = new CustomAdapter(ListActivity.this, R.layout.list_row, myArrayList); 
    myList.setAdapter(adapter); 
    //adapter.notifyDataSetChanged(); 
    dialog.dismiss(); 
} 

}

這裏是適配器代碼：

public class CustomAdapter extends ArrayAdapter<GetterSetter> { 

Context context; 
ArrayList<GetterSetter> placesArray; 
int textViewResourceId; 

public CustomAdapter(Context context, int textViewResourceId, List<GetterSetter> objects) { 
    super(context, textViewResourceId, objects); 
    this.placesArray = (ArrayList<GetterSetter>) objects; 
    this.context = context; 
    this.textViewResourceId = textViewResourceId; 

} 

@Override public View getView(int position, View convertView, ViewGroup parent) { 
    View row = convertView; 
    TextViewHolder holder = null; 

    if (row == null) { 
     LayoutInflater inflater = ((Activity) context).getLayoutInflater(); 
     row = inflater.inflate(textViewResourceId, parent, false); 

     holder = new TextViewHolder(); 
     holder.name = (TextView) row.findViewById(R.id.name); 
     holder.rating = (TextView) row.findViewById(R.id.rating); 
     holder.ratingText = (TextView) row.findViewById(R.id.ratingRext); 
     row.setTag(holder); 
    } else { 
     holder = (TextViewHolder) row.getTag(); 
    } 

    holder.name.setText(placesArray.get(position).name); 
    holder.rating.setText(placesArray.get(position).rating); 

    return row; 
} 

static class TextViewHolder { 
    TextView name; 
    TextView rating; 
    TextView ratingText; 
} 
    } 

Answer 1

addValues = new GetterSetter();你使用一個對象，並添加一個相同的對象多次。

所以你應該在你的for loop

創建GetterSetter對象，因爲你必須克里特島相同數量的對象，因爲他們是你的解析對象/數組中
