我正在开发一个Android应用程序,我正在使用Android ListView.我从Web服务获取数据并将其填入Arraylist.它的大小是37.然后我尝试用Arraylist填充listview,但它总是得到相同的元素(最后一个).您可以在下面看到代码部分:

private void ctv_listele(String res){
ArrayList<CTV> ctvList = new ArrayList<CTV>();

try {
    JSONObject jsonObject = new JSONObject(res);
    JSONArray jsonArray = jsonObject.getJSONArray("tarife");
    int max = jsonArray.length();
    for(int i = 0; i < max; i++) {
        JSONObject tmp = jsonArray.getJSONObject(i);
        ctv.setYear(tmp.getString("Year"));
        ctv.setYearlyCost(tmp.getString("YearlyCost"));
        ctv.setMonthlyCost(tmp.getString("MonthlyCost"));
        ctv.setGroup(tmp.getString("Group"));
        ctv.setDegree(tmp.getString("Degree"));
        Log.e("Added",tmp.getString("YearlyCost"));
        ctvList.add(ctv);
    }
    Log.e("End",String.valueOf(ctvList.size()));
} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
  ListView productList = (ListView) findViewById(R.id.listView_ctv);
  MyCustomAdapter adapter = new MyCustomAdapter(this, R.layout.ctv_row, ctvList);
  productList.setAdapter(adapter);

}


public class MyCustomAdapter extends ArrayAdapter<CTV>{
