Android onLocationChanged内容应该是什么

我知道这个问题在SO中被问了很多次，我试着关注20个网页的内容。。 等…等…页

基本上我的代码是Androidhive.info

我的问题是-在log cat中，它显示了位置，但没有保存在我的数据库中

我在服务器上有一个php文件，我在点击按钮时通过httppost调用它。我的座右铭是

1.单击按钮时，应发送此任务已完成的位置

2.应用程序应在后台运行，并在时间间隔内发送位置详细信息任务待定

正如中所建议的，我已经扩展了服务，但我没有在这里使用任何报警管理器或作业调度程序

这使我的代码变得笨拙

所以我的问题是，应该用onLocationchanged方法编写什么代码，这样每当位置发生变化时，它就会向服务器发送数据。该程序每n分钟运行一次

代码片段：：

1.GPSTracker.java

public class GPSTracker extends  Service implements LocationListener
{
statements;
} 

public void onLocationChanged(Location location)
{
    latitude = location.getLatitude();
    longitude = location.getLongitude();
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0, this); 
    Log.e("onLocationChanged",Double.toString(latitude));
    Log.e("onLocationChanged",Double.toString(longitude));
}

2.GPSTracker.java中的某些部分

public class GPSTracker extends  Service implements LocationListener
{
statements;
} 

public void onLocationChanged(Location location)
{
    latitude = location.getLatitude();
    longitude = location.getLongitude();
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0, this); 
    Log.e("onLocationChanged",Double.toString(latitude));
    Log.e("onLocationChanged",Double.toString(longitude));
}

3.MainActivity.java

btnShowLocation.setOnClickListener(new View.OnClickListener()

    @Override
    public void onClick(View arg0)
    {
        new LongOperation().execute();
    }
}

        {
            ArrayList<NameValuePair> paramss = new ArrayList<NameValuePair>();
            paramss.add(new BasicNameValuePair("latti", latti));
            paramss.add(new BasicNameValuePair("longi", longi));

                Toast.makeText(getApplicationContext(), "Invalid IP Address",
                        Toast.LENGTH_LONG).show();
            }

            try

            }
            return null;
          }
        }

每分钟它都会在日志中给我位置更新。但这些数据不会发送到数据库

我已经在doInBackground中编写了http调用，因此控件不会传递给该方法…它再也不会被调用

当我使用pending intent时，此屏幕是输出，即使我的GPS设置已启用

新增代码：：

public Location getLocation()
    {
        try
        {
            intent = new Intent("com.example.dotweb.mylocation");
            pi = PendingIntent.getBroadcast(getApplicationContext(),0, intent, 0);

            locationManager = (LocationManager) mContext

            isGPSEnabled = locationManager
                    .isProviderEnabled(LocationManager.GPS_PROVIDER);

            isNetworkEnabled = locationManager
                    .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

            if (!isGPSEnabled && !isNetworkEnabled) {
            } else {
                this.canGetLocation = true;
                if (isNetworkEnabled)
                {
                    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,60000,0, this);
                    Log.d("Network", "Network");
                    if (locationManager != null)
                    {
                        location = locationManager
                                .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                        if (location != null) {
                            latitude = location.getLatitude();
                            longitude = location.getLongitude();
                        }
                    }
                }
                if (isGPSEnabled) {
                    if (location == null)
                    {
                        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,60000,0, this);
                        Log.d("GPS Enabled", "GPS Enabled");
                        if (locationManager != null) {
                            location = locationManager
                                    .getLastKnownLocation(LocationManager.GPS_PROVIDER);
                            if (location != null) {
                                latitude = location.getLatitude();
                                longitude = location.getLongitude();
                            }
                        }
                    }
                }
            }

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

        return location;
    }

都不是locationManager.requestLocationUpdatesLocationManager.GPS\U提供程序，60000,0，此； nor locationManager.requestLocationUpdatesLocationManager.GPS_提供程序，60000,0，pi；他在耍花招

onLocationChanged内容

LongOperation是一个具有http调用的AsyncTask类

每n分钟，我们就要把LongOperationdoInBackground称为LongOperationdoInBackground；怎么做@Abhishek Chaubey..我已经添加了日志，…看，我在日志中每分钟都有一次更新，但在数据库中没有更新您正在请求onLocationchanged内部的位置更新。最初你曾要求过。一旦您成功请求，无论何时根据您的配置更改位置，都只会调用onLocationChanged。还有一个建议，而不是使用Android API 1位置管理器。尝试使用新的FusedLocationProviderApi。确切地说是@Vignesh…根据提到的时间60000，一个呼叫将被更改为onLocationChanged…如果您查看日志，它每分钟都显示我的位置…但是这些数据没有被发送到数据库…这是我最头疼的问题
