我想加载JSONArray并设置为listview。
这是我的one_fragment，我将数据加载到listiview

这是我的OneFragment，我加载json数据并存储到适配器
public class OneFragment extends Fragment {
View rootView;
JSONObject jsonObject;
List<Score> list=new ArrayList<Score>();
ListView lst;
FullScoreAdapter adapter=null;
private static final String url="http://10.0.2.2/JSON/fullLitz.php";
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_one, container, false);
new JSONLoader().execute();
return rootView;
}
public class JSONLoader extends AsyncTask<String, String, JSONObject> {
private ProgressDialog dialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
dialog = new ProgressDialog(getActivity());
dialog.setMessage("Getting....");
dialog.setIndeterminate(false);
dialog.setCancelable(true);
dialog.show();
}
@Override
protected JSONObject doInBackground(String... params) {
JSONParser parser = new JSONParser();
jsonObject = parser.getJSONFromUrl(url);
return jsonObject;
}
@Override
protected void onPostExecute(JSONObject jsonObject) {
dialog.dismiss();
try {
JSONObject mainObject = new JSONObject(jsonObject.toString());
String status = mainObject.getString("status");
String version = mainObject.getString("version");
String status_code = mainObject.getString("status_code");
String Etag = mainObject.getString("Etag");
String cache_key = mainObject.getString("cache_key");
JSONObject dataObject = mainObject.getJSONObject("data");
JSONObject cardObject = dataObject.getJSONObject("card");
JSONObject innings = cardObject.getJSONObject("innings");
JSONObject b_1=innings.getJSONObject("b_1");
JSONArray batting_order=b_1.getJSONArray("batting_order");
int length=batting_order.length();
ArrayList<String> p_name=new ArrayList<String>();
Score s=new Score();
//for(int j=0;j<length;j++) {
for (int i = 0; i < batting_order.length(); i++) {
p_name.add(batting_order.getString(i));
}
//p_name.add(batting_order.getString(j));
//}
s.setPlayernames(p_name);
list.add(s);
lst=(ListView)rootView.findViewById(R.id.listview);
adapter=new FullScoreAdapter(getContext(),list,length);
lst.setAdapter(adapter);
}
catch (JSONException e){
e.printStackTrace();
}
}
}
}
这里，我的list_rows.xml是否可以创建自定义列表视图

这里，我的FullScoreAdapter.java是否会使list_rows.xml膨胀并设置为OneFragment.java
public class FullScoreAdapter extends BaseAdapter {
private static final int TYPES_COUNT = 2;
private static final int TYPE_LEFT = 0;
private static final int TYPE_RIGHT = 1;
private Context context;
private List<Score> items,lst;
private int length;
private static LayoutInflater inflater;
public FullScoreAdapter(Context context,List<Score> items,int length){
this.context=context;
this.items=items;
this.length=length;
inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return items.size();
}
@Override
public Object getItem(int position) {
return items.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
public class Holder {
TextView txtname;
TextView txtballs;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
Holder holder=new Holder();
final View view;
view = inflater.inflate(R.layout.list_rows, null);
holder.txtname=(TextView)view.findViewById(R.id.txtName);
holder.txtballs=(TextView)view.findViewById(R.id.txtBalls);
Score score=items.get(position);
String batting="";
for(String str:score.getPlayernames()){
//batting+=str;
Log.e("BESTMAN NAME", str);
holder.txtname.setText(str);
}
return view;
}
}
这是我的score.java类，它有setter和getter方法。
package com.domore.tabfinaldemo;
import java.util.List;
public class Score {
private List<String> playernames;
private String target;
public List<String> getPlayernames() {
return playernames;
}
public void setPlayernames(List<String> playernames) {
this.playernames = playernames;
}
public String getTarget() {
return target;
}
public void setTarget(String target) {
this.target = target;
}
}
这是我要加载的json数据

以上json文件不完整我只发布我需要解决的帖子。
我想在局内获得batting_order-＆gt; b_1-＆gt;击球顺序
我已经完成了获取batting_order数据，但它只设置在listview的单行上。
如何将单个名称设置为listview的单行？ 例如。 s_watson在第一行，a_rahane在第二行，依此类推
答案 0 :(得分：1)
如果您正在使用其他适配器模型类，我将建议您不要更改模型类，但如果您只想显示击球顺序列表，则只需在BaseAdapter中进行更改。如果你只想显示击球顺序列表
，我已经从列表更改为列表public class FullScoreAdapter extends BaseAdapter {
private static final int TYPES_COUNT = 2;
private static final int TYPE_LEFT = 0;
private static final int TYPE_RIGHT = 1;
private Context context;
private List<String> items, lst;
private int length;
int size = 0;
private static LayoutInflater inflater;
public FullScoreAdapter(Context context, List<String> items, int length) {
this.context = context;
this.items = items;
if (items != null && !items.isEmpty()) {
size = items.length();
}
this.length = length;
}
@Override
public int getCount() {
return size;
}
@Override
public String getItem(int position) {
return items.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
public class Holder {
TextView txtname;
TextView txtballs;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
Holder holder = null;
final View view;
if (convertView == null) {
holder = new Holder();
convertView =LayoutInflater.from(this.context).inflate(R.layout.list_rows, parent,false);
holder.txtname = (TextView) convertView.findViewById(R.id.txtName);
holder.txtballs = (TextView) convertView.findViewById(R.id.txtBalls);
convertView.setTag(holder);
} else {
holder = (Holder) convertView.getTag();
//check answer for baseadapter
//http://stackoverflow.com/a/34349311/1140237
}
//Score score = items.get(position);
String batting = "";
holder.txtname.setText(this.items.get(position));
return convertView;
}
}
更改 onPostExecute
protected void onPostExecute(JSONObject jsonObject) {
dialog.dismiss();
try {
JSONObject mainObject = new JSONObject(jsonObject.toString());
String status = mainObject.getString("status");
String version = mainObject.getString("version");
String status_code = mainObject.getString("status_code");
String Etag = mainObject.getString("Etag");
String cache_key = mainObject.getString("cache_key");

lst.setAdapter(adapter);

答案 1 :(得分：0)
我认为这是你的代码中的错误
JSONArray batting_order=b_1.getJSONArray("batting_order");
int length=batting_order.length();
ArrayList<String> p_name=new ArrayList<String>();
Score s=new Score();
for(int j=0;j<length;j++) {
p_name.add(batting_order.getString(j));
}
s.setPlayernames(p_name);
list.add(s);
YOur Score class ::
public class Score {
private String playernames;
private String target;
public String getPlayernames() {
return playernames;
}
public void setPlayernames(String playernames) {
this.playernames = playernames;
}
public String getTarget() {
return target;
}
public void setTarget(String target) {
this.target = target;
}
}
