Android onLocationChanged方法不调用
我搜索了很多,在stackoverflow里面也看到了很多帖子,但是没有得到回复,或者说不清楚也不复杂。很简单,我想在从emulator控件发送经度和纬度时调用onLocationChanged方法,所以我在main.xml文件中编写了以下代码:Android onLocationChanged方法不调用,android,location,Android,Location,我搜索了很多,在stackoverflow里面也看到了很多帖子,但是没有得到回复,或者说不清楚也不复杂。很简单,我想在从emulator控件发送经度和纬度时调用onLocationChanged方法,所以我在main.xml文件中编写了以下代码: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tool

此代码在emulator上工作
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListner);
我认为问题在于,您正在向网络提供商请求更新,而仿真器使用GPS提供商 尝试更改: locationManager.requestLocationUpdatesLocationManager.NETWORK\u提供程序,0,0,locationListner 与:
locationManager.requestLocationUpdatesLocationManager.GPS_提供程序,0,0,locationListner 尝试在活动类上实现LocationListener
public class Main extends Activity implements LocationListener {
@Override
public void onLocationChange(Location location){
// do something
}
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListner);
public class Main extends Activity implements LocationListener {
@Override
public void onLocationChange(Location location){
// do something
}
}
