ArrayList <hashmap <string，string =“”>＆gt;通过json </hashmap <string，>到php

Question

我会通过json将“jsonlist”（ArrayList <HashMap <String, String >>）传递给php。

任何人都可以帮助我吗？

    package ctb.manutenzione;

    import java.util.ArrayList;
    import java.util.HashMap;
    import org.json.JSONArray;
    import org.json.JSONException;
    import org.json.JSONObject;
    import ctb.manutenzione.library.JSONParser;
    import android.app.ListActivity;
    import android.app.ProgressDialog;
    import android.content.Context;

    import android.os.Bundle;
    import android.view.View;
    import android.widget.Button;
    import android.widget.ListAdapter;
    import android.widget.SimpleAdapter;

    public class ManutenzioneGiornaliera extends ListActivity {
       private static final String Campo1 = "phpCampo1";
       private static final String Campo2 = "phpCampo2";
       public String percorsoPHP;
       String url;
       ArrayList<HashMap<String, String>> jsonlist = new ArrayList<HashMap<String, String>>();

       @Override
       public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_manutenzionegiornaliera);

        url= ("http://192.0.0.1/ctb/mangiornaliera.php");

        Button startBtn = (Button) findViewById(R.id.inviamanutenzione);
        startBtn.setOnClickListener(new View.OnClickListener() {
           public void onClick(View view) {
              //todo
           }
        });
        new ProgressTask(ManutenzioneGiornaliera.this).execute();
       }

       public class ProgressTask extends AsyncTask<String, Void, Boolean> {
        private ProgressDialog dialog;

        // private List<Message> messages;
        public ProgressTask(ListActivity activity) {
            context = activity;
            dialog = new ProgressDialog(context);
        }

        private Context context;

        protected void onPreExecute() {
            this.dialog.setMessage("Progress start");
            this.dialog.show();
        }

        @Override

        protected void onPostExecute(final Boolean success) {
            if (dialog.isShowing()) {
                dialog.dismiss();
            }

             ListAdapter adapter = new SimpleAdapter(
                    context,
                    jsonlist,
                    R.layout.activity_manutenzionegiornaliera_row,
                    new String[]{Campo1, 
                                 Campo2},
                    new int[]{R.id.Campo1, 
                              R.id.Campo2}
                    );
              setListAdapter(adapter);
            }

        protected Boolean doInBackground(final String... args) {

            jsonlist.clear();

            JSONParser sitoLogin = new JSONParser();
            String[] params = new String[1];

            JSONArray json;
            try {
                json = sitoLogin.getJSONFromUrl5(url, params);
                for (int i = 0; i < json.length(); i++) {

                    try {
                        JSONObject c = json.getJSONObject(i);
                        String campo1 = c.getString(Campo1);
                        String campo2 = c.getString(Campo2);

                        HashMap<String, String> map = new HashMap<String, String>();

                        // Add child node to HashMap key & value
                        map.put(Campo1, campo1);
                        map.put(Campo2, campo2);
                        jsonlist.add(map);
                    }               
                    catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            } catch (Exception e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }
            return null;
        }
       }
 }

从json = sitoLogin.getJSONFromUrl5(url, params);我得到一些来自php的查询返回的记录
