我正在创建app，在我的活动中我使用了getIntent.getstringExtra（“string”），这个字符串包含json响应，在该响应中我有不同的字段，我需要在列表视图中显示，所以如何做到这一点< / p>
检查此问题How to display response in next activity
class AttemptLogin extends AsyncTask<String, String, String> {
boolean failure = false;
JSONObject jobj;
String resultname;
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(getActivity());
pDialog.setMessage("Processing..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();

我的适配器类
public class CustomAdapterSearch extends BaseAdapter{
private Context context;
private ArrayList<HashMap<String,String>> listData;
private AQuery aQuery;
private static final String TAG_NAME="name";
private static final String TAG_PROFILE="profile_id";
private static final String TAG_IMAGE="image";
private static final String TAG_CAST="cast";
private static final String TAG_AGE="age";
private static final String TAG_LOCATION="location";
public CustomAdapterSearch(Context context,ArrayList<HashMap<String,String>> listData) {
this.context = context;
this.listData=listData;
aQuery = new AQuery(this.context);
}
@Override
public int getCount() {
return listData.size();
}
@Override
public Object getItem(int position) {
return listData.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.list_item_searchresult, null);
holder.propic = (ImageView) convertView.findViewById(R.id.propicsearch);
holder.txtproname = (TextView) convertView.findViewById(R.id.txtpronamesearch);
holder.txtproid = (TextView) convertView.findViewById(R.id.txtproidsearch);

}
holder.txtproname.setText(listData.get(position).get(TAG_NAME));
holder.txtproid.setText(listData.get(position).get(TAG_PROFILE));
holder.txtprofilecast.setText(listData.get(position).get(TAG_CAST));
holder.txtprofileage.setText(listData.get(position).get(TAG_AGE));

aQuery.id(holder.propic).image(listData.get(position).get(TAG_IMAGE),true,true,0,R.drawable.ic_launcher);
// image parameter : 1 : memory cache,2:file cache,3:target width,4:fallback image

答案 0 :(得分：0)
你试试这段代码吗？
public ArrayList<String> name = new ArrayList<>();
public ArrayList<String> description = new ArrayList<>();
try {
JSONObject jsonObj = new JSONObject(jsonStr);
JSONArray building = jsonObj.getJSONArray("data");
for (int i = 0; i < building.length(); i++) {
JSONObject c = building.getJSONObject(i);
String namec = c.getString("title");
String descriptionc = c.getString("description");
name.add(namec);
description.add(descriptionc);
}
} catch (JSONException e) {
e.printStackTrace();
}
for (int i = 0; i < name.size(); i++) {
la.add(new JSONList(name.get(i), description.get(i)));
}
lv.setAdapter(la);
jsonStr是你的json字符串，＆＃34;数据＆＃34;是json数组名称。
la是ListAdapter（自定义适配器），lv是ListView。
我建议使用AsyncTask将Json打印到ListView。
修改：
public ArrayList<String> user_login_id = new ArrayList<>();
public ArrayList<String> age_from = new ArrayList<>();
try {
JSONObject jsonObj = new JSONObject(json.getString(TAG_SUCCESS));
JSONArray data = jsonObj.getJSONArray("searchresult");
for (int i = 0; i < data.length(); i++) {
JSONObject c = data.getJSONObject(i);
String user_login_idc = c.getString("user_login_id");
String age_fromc = c.getString("age_from");
...
user_login_id.add(user_login_idc);
age_from.add(age_fromc);
...
}
} catch (JSONException e) {
e.printStackTrace();
}
在onPostExecute
中 for (int i = 0; i < age_from.size(); i++) {
la.add(new JSONList(user_login_id.get(i), age_from.get(i) ...));
}
lv.setAdapter(la);
<强> 修改 ：
所以，你可以尝试这段代码。
List.class
public class List {
Drawable Propic;
String txtproname, txtproid, txtprofilecast, txtprofileage, txtprofileplace;
public List(drawable propic, String txtproname, String txtproid, String txtprofilecast, String txtprofileage, String txtprofileplace) {
this.propic = propic;
this.txtproname = proname;
this.txtproid = proid;
this.txtprofileage = txtprofileage;
this.txtprofileplace = txtprofileplace;
}
public Drawable getpropic() { return propic;}
public String gettxtproname() { return txtproname;}
public String txtproid() { return txtproid;}
public String txtprofileage() { return txtprofileage;}
public String txtprofileplace() { return txtprofileplace;}
}
所以，您可以简单地使用适配器
final List data = this.getItem(position)
holder.txtproname.setText(data.getproname());
holder.txtproid.setText(data.gettxtproid());
holder.txtprofilecast.setText(data.gettxtprofilecast());
holder.txtprofileage.setText(data.gettxtprofileage());
holder.txtprofileplace.setText(data.gettxtprofileplace());
在onPostExecute
中 for (int i = 0; i < age_from.size(); i++) {
la.add(new List(user_login_id.get(i), age_from.get(i) ...));
}
lv.setAdapter(la);
