我想加载 JSONArray 并设置到 ListView 中。

这是我的 one_fragment，我将数据加载到 listiview 中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

        <LinearLayout

            android:layout_height="35dp"
            android:paddingLeft="5dp"
            android:orientation="horizontal">
            <TextView

            <TextView
                android:id="@+id/txtlblRuns"
                android:layout_width="wrap_content"

                android:textColor="#FFFFFF"
                android:layout_marginLeft="15dp"
                android:layout_gravity="center"

            android:layout_height="fill_parent">
        </ListView>
    </LinearLayout>
</LinearLayout>

这是我的 OneFragment，我加载了 json 数据并将其存储到适配器中

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();
            }
        }
    }
}

这里是我的 list_rows.xml 来创建自定义 ListView

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical"
        android:background="#3C3C3C">
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="35dp"
            android:paddingLeft="5dp"
            android:orientation="horizontal">
            <TextView
                android:id="@+id/txtName"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor="#FFFFFF"
                android:layout_gravity="center"
                android:textSize="10dp"
                android:text="IND-250/4(ovr-90)"/>
            <View
                android:layout_width="110dp"
                android:layout_height="wrap_content" />
            <TextView
                android:id="@+id/txtRuns"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor="#FFFFFF"
                android:layout_gravity="center"
                android:textSize="10dp"
                android:text="R"/>

            <TextView
                android:id="@+id/txtBalls"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor="#FFFFFF"
                android:layout_marginLeft="15dp"
                android:layout_gravity="center"
                android:textSize="10dp"
                android:text="B"/>

            <TextView
                android:id="@+id/txtFours"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor="#FFFFFF"
                android:layout_marginLeft="15dp"
                android:layout_gravity="center"
                android:textSize="10dp"
                android:text="4s"/>

            <TextView
                android:id="@+id/txtSixs"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textColor="#FFFFFF"
                android:layout_marginLeft="15dp"
                android:layout_gravity="center"
                android:textSize="15dp"
                android:text="6s"/>
        </LinearLayout>
        </LinearLayout>
</LinearLayout>

这是我的 FullScoreAdapter.java，它膨胀 list_rows.xml 并设置到 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

上面的 json 文件不完整，我只发布了我需要解决这个问题。

我想得到局内的batting_order->b_1->batting order

我已经完成获取 batting_order 数据，但它仅在 ListView 的单行上设置。

如何将单个名称设置为 ListView 的单行？？例如。第一行是s_watson，第二行是a_rahane等等

最佳答案

如果您使用此适配器以外的 Score 模型类，我会建议您不要更改模型类，但如果您只想显示击球顺序列表，请在 BaseAdapter 中进行更改。如果您只想显示击球顺序列表，这里我已从列表更改为列表

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;
            }

        }

onPostExecute 的变化

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(),p_name,length);

                lst.setAdapter(adapter);
            }
            catch (JSONException e){
                e.printStackTrace();
            }
        }
