Androidはint型の数値をmysqlデータベースから時刻形式に変換します

Question

mysqlデータベースから時刻形式に変換する整数値をどのように変換できますか？ここに私のjavaファイルはarrayAdapter

public class parking_records extends ArrayAdapter<String> { 
private String[] Parking_Start_Time; 
private String[] Parking_End_Time; 
private String[] Duration; 

private Activity context; 

public parking_records(Activity context, String[] Parking_Start_Time, String[] Parking_End_Time, String[] Duration) { 
    super(context, R.layout.fragment_parking_record, Parking_Start_Time); 
    this.context = context; 
    this.Parking_Start_Time = Parking_Start_Time; 
    this.Parking_End_Time = Parking_End_Time; 
    this.Duration = Duration; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    LayoutInflater inflater = context.getLayoutInflater(); 
    View listViewItem = inflater.inflate(R.layout.fragment_parking_record, null, true); 
    TextView textViewPRd = (TextView) listViewItem.findViewById(R.id.textViewPRd); 
    TextView textViewPRd1 = (TextView) listViewItem.findViewById(R.id.textViewPRd1); 
    TextView textViewPRr = (TextView) listViewItem.findViewById(R.id.textViewPRr); 

    textViewPRd.setText(Parking_Start_Time[position]); 
    textViewPRd1.setText(Parking_End_Time[position]); 
    textViewPRr.setText(Duration[position]); 

    return listViewItem; 
} 
} 

Parking_Records.java

public class Parking_Records { 

public static String[] Parking_Start_Time; 
public static String[] Parking_End_Time; 
public static String[] Duration; 

public static final String JSON_ARRAY = "result"; 
public static final String KEY_ParkStartTime = "Parking_Start_Time"; 
public static final String KEY_ParkEndTime = "Parking_End_Time"; 
public static final String KEY_ParkDuration = "Duration"; 


private JSONArray users = null; 

private String json; 

public Parking_Records(String json){ 
    this.json = json; 
} 

public void parseJSON(){ 
    JSONObject jsonObject=null; 
    try { 
     jsonObject = new JSONObject(json); 
     users = jsonObject.getJSONArray(JSON_ARRAY); 

     Parking_Start_Time = new String[users.length()]; 
     Parking_End_Time = new String[users.length()]; 
     Duration = new String[users.length()]; 


     for(int i=0;i<users.length();i++){ 
      JSONObject jo = users.getJSONObject(i); 
      Parking_Start_Time[i] = jo.getString(KEY_ParkStartTime); 
      Parking_End_Time[i] = jo.getString(KEY_ParkEndTime); 
      Duration[i] = jo.getString(KEY_ParkDuration); 

     } 
    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 
} 
} 

メインParking_Records_Fragment.java

public class ParkingRecordFragment extends Fragment implements View.OnClickListener, SwipeRefreshLayout.OnRefreshListener { 

ProgressDialog dialog; 

String url; 

SessionManager session; 
private String Username; 
private String Acc_Pass; 
SharedPreferences shared; 
private SwipeRefreshLayout mSwipeRefreshLayout; 

public ParkingRecordFragment() { 
    // Required empty public constructor 
} 

private ListView listView; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    ((AppCompatActivity)getActivity()).getSupportActionBar().setTitle("Parking Record"); 
    // Session class instance 
    session = new SessionManager(getActivity().getApplicationContext()); 

    dialog = new ProgressDialog(getActivity()); 
    dialog.setMessage("Loading...."); 
    dialog.show(); 

    View rootView = inflater.inflate(R.layout.activity_listview_parking_records, container, false); 

    listView = (ListView) rootView.findViewById(R.id.listView); 
    listView.setEmptyView(rootView.findViewById(R.id.empty_list_item)); 
    mSwipeRefreshLayout = (SwipeRefreshLayout) rootView.findViewById(R.id.swipe_refresh_layout); 
    mSwipeRefreshLayout.setOnRefreshListener(this); 

    mSwipeRefreshLayout.postDelayed(new Runnable() { 
     @Override 
     public void run() { 
      mSwipeRefreshLayout.setRefreshing(false); 
      sendRequest(Username, Acc_Pass); 
     } 
    }, 1000); 

    sendRequest(Username, Acc_Pass); 
    shared= getActivity().getSharedPreferences("Mypref", Context.MODE_PRIVATE); 

    return rootView; 

} 

@Override 
public void onRefresh() { 
    sendRequest(Username, Acc_Pass); 
} 

private void sendRequest(String Username, String Acc_Pass){ 

    HashMap<String, String> user = session.getUserDetails(); 
    Username = user.get(SessionManager.KEY_USERNAME); 
    Acc_Pass = user.get(SessionManager.KEY_PASSWORD); 

    RequestQueue requestQueue = VolleyController.getInstance(getActivity().getApplicationContext()).getRequestQueue(); 

    String url = "http://192.168.1.5/json_parking_records2.php?Username="+Username+"&Acc_Pass="+Acc_Pass+""; 
    url = url.replaceAll(" ", "%20"); 
    try { 
     URL sourceUrl = new URL(url); 
    } catch (MalformedURLException e) { 
     e.printStackTrace(); 
    } 
    Log.i("Getting url info",""+url); 

    StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() { 

     @Override 
     public void onResponse(String response) { 
      showJSON(response); 
      dialog.dismiss(); 
      mSwipeRefreshLayout.setRefreshing(false); 
     } 
    }, new Response.ErrorListener() { 
     @Override 
     public void onErrorResponse(VolleyError error) { 
      Toast.makeText(getActivity().getApplicationContext(),error.getMessage(),Toast.LENGTH_LONG).show(); 
      dialog.dismiss(); 
     } 
    }); 

    requestQueue.add(stringRequest); 
} 

private void showJSON(String json){ 
    Parking_Records pj = new Parking_Records(json); 
    pj.parseJSON(); 
    parking_records cl = new parking_records(getActivity(), Parking_Records.Parking_Start_Time, Parking_Records.Parking_End_Time, Parking_Records.Duration); 
    listView.setAdapter(cl); 
} 

@Override 
public void onClick(View v) { 
    sendRequest(Username, Acc_Pass); 
} 
} 

と

parking_records.javaです
