我有一个列表视图，其中包含来自 twitter 的数据。我想显示推特，但它在每个推特项目中都显示了用户。所以我想为其他用户显示默认图片。我的代码正在运行，但是当我移动 listview 时，每个用户的用户个人资料图像都会再次出现。我该如何解决？如果它是转推，则在代码“rt”中。
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (null != pDialog && pDialog.isShowing()) {
pDialog.dismiss();
}
if (null == result || result.length() == 0) {
showToast("Bağlantı yok");
Twitter.this.finish();
} else {
List<String> galleryImages = new ArrayList<String>();
try { JSONObject jsonObject = new JSONObject(result);
veriArray = jsonObject.getJSONArray("results");
int nVeri = veriArray.length();
for (int i = 0; i < nVeri; i++) {
JSONObject veriObject = veriArray.getJSONObject(i);
baslik = veriObject.getString("text");
kImaj = veriObject.getString("profile_image_url");
kisaAciklama = veriObject.getString("from_user_name");
Item objItem = new Item();
rt=baslik.substring(0, 2);
if(rt.equals(kiyas)){
kImaj="";
objItem.setLink(kImaj);
objItem.setName(baslik);}
else {
objItem.setLink(kImaj);
objItem.setName(baslik);
}
arrayOfList.add(objItem);
//objItem.setLink(link);
}
} catch (JSONException e)
{ e.printStackTrace(); } }
Collections.sort(arrayOfList, new Comparator<Item>() {
public int compare(Item lhs, Item rhs) {
return (lhs.getAge() - rhs.getAge());
}
});
setAdapterToListview();
}
}
