JSONは、AndroidエミュレータでのListViewに

Question

私のPHPを表示することはできません。

[ 
{ 
salesschedulename: "Visiting Client,", 
salesscheduledate: "2018-01-18", 
salesscheduletime: "10:30:00", 
salesscheduleaddress: "Auckland", 
salesscheduledescription: "Sales Visit" 
}, 
{ 
salesschedulename: "Hunting Client", 
salesscheduledate: "2018-01-21", 
salesscheduletime: "09:00:00", 
salesscheduleaddress: "Sidney", 
salesscheduledescription: "Sales Propose" 
}, 
{ 
salesschedulename: "Visitng Client", 
salesscheduledate: "2018-01-25", 
salesscheduletime: "09:00:00", 
salesscheduleaddress: "Bali, Indonesia", 
salesscheduledescription: "Sales Propose" 
} 

]

問題は次のとおりです：ここにPHPの結果の

<?php

//database constants 
require_once 'includes/config.php'; 

// Connecting to mysql database

     array_push($schedule, $temp); 

    } 
    }else 
    { 
    } 
    $stmt->close(); 
} 

//displaying the result in json format 
echo json_encode($schedule); 

このデータはできませんアンドロイドエミュレータで表示

ScheduleList.Java

public class ScheduleList { 

    private String ScheduleName; 
    private String ScheduleDate; 
    private String ScheduleTime; 
    private String ScheduleAddress; 
    private String ScheduleDescription; 


    public ScheduleList(String scheduleName, String scheduleDate, String scheduleTime, String scheduleAddress, String scheduleDescription) { 
     ScheduleName = scheduleName; 
     ScheduleDate = scheduleDate; 
     ScheduleTime = scheduleTime;

最後ここに（サンプル+ JSONで）私のScheduleFragment.java

    // Inflate the layout for this fragment 
    View view = inflater.inflate(R.layout.fragment_schedule, container, false); 

    final ArrayList<ScheduleList> schedule = new ArrayList<>(); 

    try { 

     JSONArray jsonArray=new JSONArray(getURL(AppConfig.URL_SCHEDULELIST)); 
     //iterate loop 
     for(int i=0;i<jsonArray.length();i++){ 

      //get the JSON Object 
      JSONObject schedules=jsonArray.getJSONObject(i); 


      //prepare data to schedule list 
      String scheduleName = schedules.getString("salesschedulename"); 
      String scheduleDate = schedules.getString("salesscheduledate"); 
      String scheduleTime = schedules.getString("salesscheduletime"); 
      String scheduleAddress = schedules.getString("salesscheduleaddress"); 
      String scheduleDescription = schedules.getString("salesscheduledescription"); 

      //adding the schedule to schedule list 

      schedule.add(new ScheduleList(scheduleName, scheduleDate, scheduleTime, scheduleAddress, scheduleDescription)); 

     } 



    } catch (Exception e) { 

     System.out.println(e.getMessage()); 

     Toast toast = Toast.makeText(
       //getActivity(),"Custom Toast From Fragment",Toast.LENGTH_LONG 
       getActivity().getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG 
     ); 
     // Set the Toast display position layout center 
     toast.setGravity(Gravity.CENTER,0,0); 
     // Finally, show the toast 
     toast.show(); 

    } 

    //sampledata 
    //schedule.add(new ScheduleList("test5", "test6", "test7", "test8", "test9")); 



    BindDictionary<ScheduleList> dictionary = new BindDictionary<>(); 
    dictionary.addStringField(R.id.sales_schedule_name, new StringExtractor<ScheduleList>() { 
     @Override 
     public String getStringValue(ScheduleList schedule1, int position) { 
      return schedule1.getScheduleName(); 
     } 
    }); 

    dictionary.addStringField(R.id.sales_schedule_date, new StringExtractor<ScheduleList>() {

    FunDapter adapter = new FunDapter(ScheduleFragment.this.getActivity(),schedule, R.layout.schedule_list_layout,dictionary); 

    ListView listView=(ListView) view.findViewById(R.id.schedule_list); 
    listView.setAdapter(adapter); 

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id){ 
      ScheduleList selecteditem = schedule.get(position); 
      Toast.makeText(ScheduleFragment.this.getActivity(),selecteditem.getScheduleName(), Toast.LENGTH_LONG).show(); 
     } 
    }); 

    return view; 

} 

public static String getURL(String url) throws Exception { 
    URL website = new URL(url); 
    URLConnection connection = website.openConnection(); 
    BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream(),"UTF8")); 

    StringBuilder response = new StringBuilder(); 
    String inputLine; 
    String result; 
    while ((inputLine = in.readLine()) != null) { 
     response.append(inputLine); 
    } 
    result=response.toString(); 
    in.close(); 

    return result; 
} 

そして、他の問題があり、それは私のデバイスが、カントショーに表示することができます他のデバイスとエミュレータで（ローカルおよび外部のPHPサーバーの両方）私はすでに入れdepedencies上

： コンパイル 'com.github.amigold.fundapter：ライブラリ：1.0'

と私はすでにあまりにもマニフェストに変更。

エラーは見つかりませんでしたが、エミュレータで表示できません。

そんなにはここ

を助けるために感謝し、私のAppConfig.java

public class AppConfig { 

    // Server user login url 
    public static String URL_LOGIN = "http://192.168.43.146/android/login.php"; 

    // Server user register url 
    public static String URL_REGISTER = "http://192.168.43.146/android/register.php"; 

    // Server user schedule url 
    public static String URL_SCHEDULELIST = "http://192.168.43.146/android/schedulelist.php"; 


    Server user schedule url 
    public static String URL_ITEMLIST = "http://192.168.43.146/android/itemlist.php"; 

}

Answer 1

エミュレータでgoogleplayを更新した後、すべて正常に動作しています。 やご質問は、環境をランタイムに主に関連すると思われるようあなたは、Androidのエミュレータタグを追加する必要があります主な活動にすべてのあなたのための

if (android.os.Build.VERSION.SDK_INT > 9) { 
     StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
     StrictMode.setThreadPolicy(policy); 
    } 

おかげで（SuperFADX、ハンザ及びその他）

変更この行：このいずれかで

JSONArray jsonArray=new JSONArray(getURL(AppConfig.URL_SCHEDULELIST)); 

：

String page = new Communicator().executeHttpGet(AppConfig.URL_SCHEDULELIST); 
JSONArray jsonArray = new JSONArray(page); 

そして、それは正しくロードかどうかを確認するためにあなたのエミュレータのWebブラウザに手動でURLを開こう。
