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.
