Android的 - GPS监听器 [英] Android - GPS Listener

问题描述

我开发一个Android应用程序其中包括一些活动。
我想从GPS（ onLocationChanged ， onProviderDisabled ， onProviderEnabled ， onStatusChanged ）无论在哪个活动的用户正在使用。

我应该在哪里实施 LocationListener的为了得到这样的行为？

这是我创建的类：

 公共类MyLocationListener实现LocationListener的{私人的LocationManager的LocationManager;
私人字符串供应商;    @覆盖
公共无效onLocationChanged（位置locationGPS）{    //做一点事
}@覆盖
公共无效onStatusChanged（字符串提供商，INT地位，捆绑演员）{
    // TODO自动生成方法存根}@覆盖
公共无效onProviderEnabled（字符串提供商）{
    Log.i（===========================，=============== ===============）;
    Log.i（onProviderEnabled，==============================）;
    Log.i（===========================，=============== ===============）;}@覆盖
公共无效onProviderDisabled（字符串提供商）{    Log.i（===========================，=============== ===============）;
    Log.i（onProviderDisabled，==============================）;
    Log.i（===========================，=============== ===============）;
}
 




解决方案

在你想要启动GPS活动启动位置监听器。要启动GPS可以使用

 的LocationManager的LocationManager =（的LocationManager）getSystemService（Context.LOCATION_SERVICE）;
    LocationListener的LocationListener的=新CTLocationListener（）;
    locationManager.requestLocationUpdates（LocationManager.GPS_PROVIDER，0，1.0F，LocationListener的）;
 

和停止GPS可以使用

  locationManager.removeUpdates（LocationListener的）;
 

及其更好编写GPS的开始对的onCreate /调用onStart和GPS除去上的服务的的onDestroy并使用该服务。否则，一旦你停止了GPS开始GPS的机会又在一些设备不足50％。

I am developing an Android application which consists a few activities. I want to get updates from the GPS (onLocationChanged, onProviderDisabled, onProviderEnabled, onStatusChanged) no matter in which activity the user is currently using.

Where should I implement the LocationListener in order to get such a behaviour?

This is the class I have created:

public class MyLocationListener implements LocationListener{

private LocationManager locationManager;
private String provider;

    @Override
public void onLocationChanged(Location locationGPS) {

    //do something
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
    // TODO Auto-generated method stub

}

@Override
public void onProviderEnabled(String provider) {
    Log.i("===========================", "==============================");
    Log.i("onProviderEnabled", "==============================");
    Log.i("===========================", "==============================");

}

@Override
public void onProviderDisabled(String provider) {

    Log.i("===========================", "==============================");
    Log.i("onProviderDisabled", "==============================");
    Log.i("===========================", "==============================");
}

解决方案

Start the location listener on the activity you wants to start the gps. To start the GPS you can use

LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    LocationListener locationListener = new CTLocationListener();
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 1.0f, locationListener);

and to stop the GPS you can use

locationManager.removeUpdates(locationListener);

Its better you write the GPS start on the onCreate/onStart and the GPS remove on the onDestroy of a service and use that service. Otherwise once you stop the GPS the chance of starting the GPS again is less than 50% in some devices.
