我正在创建一个定期更新位置的服务。但是使用下面的代码,它引发了我:
runException无法在未调用Looper.prepare()
的线程内创建处理程序此代码在服务中的Async类的doInBackground内运行
private void UpdatePosition()
{
locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location location =
locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
showPosition(location);
locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
showPosition(location);
}
public void onProviderDisabled(String provider){
}
public void onProviderEnabled(String provider){
}
public void onStatusChanged(String provider, int status, Bundle extras){
Log.i("LocAndroid", "Provider Status: " + status);
}
};
locManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, 15000, 0, locationListener);
}
我正在审核几个帖子,发现请求必须在uithread中运行,但不知道如何或在何处放置它。
我能做什么?
编辑:
我只会将此添加到我的代码中,现在不会抛出任何错误
private void UpdatePosition()
{
Looper.prepare();
looper = Looper.myLooper();
locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location location =
locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
showPosition(location);
locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
showPosition(location);
}
public void onProviderDisabled(String provider){
}
public void onProviderEnabled(String provider){
}
public void onStatusChanged(String provider, int status, Bundle extras){
Log.i("LocAndroid", "Provider Status: " + status);
}
};
locManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, 15000, 0, locationListener);
}
但我不知道它是否正确......你说什么?
