我有这种方法可以将元素添加到GetterSetter类，并将它们添加到arrayList中，并添加到listView中。事情是在listView中，它只多次显示数组中的最后一项。
我不明白为什么？有什么办法吗？
这是我的代码：
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();
}
}
这是我的catLog：

这是适配器代码：
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;
}
}
最佳答案
addValues = new GetterSetter();您正在使用一个对象，并多次添加一个相同的对象。
所以您应该在GetterSetter中创建for loop对象
因为您必须创建相同数量的对象，所以它们与您解析的对象/数组中的对象数量相同
