Question

我在处理程序线程内的android服务中使用这个将数据发送到php页面以插入到mysql数据库中，url是可以的但是由于某种原因它没有被发布到php页面.url被定义为Public String on班上的开始。

public void onCreate() {
super.onCreate();

// final String mojsadrzaj=new String();

Toast.makeText(this,"Service created ...",Toast.LENGTH_LONG).show();



    final SQLiteDatabase db=openOrCreateDatabase("TruckMe", MODE_PRIVATE, null);
    db.execSQL("create table if not exists lokacije (id INTEGER  PRIMARY KEY AUTOINCREMENT NOT NULL, lokacija VARCHAR(600));");

    //regulisanje podataka za logovanje samo prvi put


    String idvozaca=new String();
    db.execSQL("create table if not exists vozac (id INTEGER  PRIMARY KEY AUTOINCREMENT NOT NULL, idvozaca VARCHAR(15));");
    Cursor d=db.rawQuery("select idvozaca from vozac", null);
    //db.execSQL("delete from vozac;");

    if(d.getCount() > 0)
    {
        d.moveToLast();
        idvozaca=d.getString(d.getColumnIndex("idvozaca"));
        mojsadrzaj=idvozaca;
        Toast t=Toast.makeText(this, "Id vozaca je : " + mojsadrzaj, Toast.LENGTH_LONG);
        t.setGravity(Gravity.CENTER, 0, 0);
        t.show();
        db.close();

    }





    //regulisanje podataka za logovanje samo prvi put

    final Time t=new Time();

    //Toast.makeText(this,"Stao kod upita" , Toast.LENGTH_LONG).show();

     //deo za thread

     final Handler handler = new Handler();
        final Runnable runnable = new Runnable() {
            public void run() {

                if(indikator != 0)
                {
                try {

                    URL myURL = new URL(url);

                    URLConnection myURLConnection = myURL.openConnection();
                    myURLConnection.connect();
                    Toast.makeText(MyService.this,"saljem na net "+url , Toast.LENGTH_LONG).show();
                } 
                catch (MalformedURLException e) { 
                    // new URL() failed
                    // ...
                } 
                catch (IOException e) {

                    // ...
                }



                }
                indikator=1;
                handler.postDelayed(this, 9000);

            }
        };


    //b.setBackgroundColor(Color.RED);

        LocationListener l=new LocationListener() {

                    String zauzetost=new String();

                String longitude=new String();

            m.requestLocationUpdates(locationprovider, 6000, 0, l);

    //      zamenio sam m.requestLocationUpdates(LocationManager.GPS_PROVIDER, 120000, 0, l); sa m.requestLocationUpdates(locationprovider, 120000, 0, l);
        }

所有这些都可以在活动中完成并使用webview发布到php页面。但由于我无法使用webview服务，我使用URL ...，在调用url之后烘烤的链接很好。这有什么问题。

Answer 1

不是使用URLConnection，而是构造HttpClient对象，以执行使用目标URL构造的HttpPost。 Jeff Vogella在第2.3节中有一个很好的例子：http://www.vogella.com/articles/ApacheHttpClient/article.html

Answer 2

我使用了这个

try {

                    URL myURL = new URL(url);

                    URLConnection myURLConnection = myURL.openConnection();
                    myURLConnection.connect();

                    //
                    BufferedReader in = new BufferedReader(new InputStreamReader(
                            myURLConnection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) 
    System.out.println(inputLine);
in.close();


                    //
                    Toast.makeText(MyService.this,"saljem na net "+url , Toast.LENGTH_LONG).show();
                } 
                catch (MalformedURLException e) { 
                    // new URL() failed
                    // ...
                } 
                catch (IOException e) {   
                    // openConnection() failed
                    // ...
                }

将数据发送到php页面
