我想通过来自广播接收器的短信发送位置信息。该代码根本无法确定我的位置。谁能帮我解决我的问题？
SmsRemoteController
public class SmsRemoteController extends BroadcastReceiver {
private static final int MODE_WORLD_READABLE = 1;
private String smsFirstCode;
private SharedPreferences myPrefs;
private Context contexts;
private String sendingNumber = "";
@Override
public void onReceive(Context context, Intent intent) {
contexts = context;
myPrefs = context.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
String smsMode = myPrefs.getString("state", "not");
AppLocationService appLocationService;
appLocationService = new AppLocationService(SmsRemoteController.class);
if (smsMode.equals("ON")) {
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String smsBody = "";
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
sendingNumber += msgs[i].getOriginatingAddress();
smsBody = msgs[i].getMessageBody().toString();
}
// Toast.makeText(contexts, "number"+sendingNumber+"..body"+smsBody.toLowerCase(), Toast.LENGTH_SHORT).show();
if (smsBody.equals("locate")) {
Location nwLocation = appLocationService.getLocation(LocationManager.NETWORK_PROVIDER);
if (nwLocation != null) {
double latitude = nwLocation.getLatitude();
double longitude = nwLocation.getLongitude();
Toast.makeText(contexts, "Mobile Location (NW): \nLatitude: " + latitude + "\nLongitude: " + longitude,
Toast.LENGTH_LONG).show();
} else {
Location gpsLocation = appLocationService.getLocation(LocationManager.GPS_PROVIDER);
if (gpsLocation != null) {
double latitude = gpsLocation.getLatitude();
double longitude = gpsLocation.getLongitude();
Toast.makeText(contexts, "Mobile Location (GPS): \nLatitude: " + latitude
+ "\nLongitude: " + longitude,
Toast.LENGTH_LONG).show();
}
}
}
//abortBroadcast();
}// end of onReceive()
}
} // end of the class
}
AppLocationService
public class AppLocationService extends Service implements LocationListener {
protected LocationManager locationManager;
Location location;
private static final long MIN_DISTANCE_FOR_UPDATE = 10;
private static final long MIN_TIME_FOR_UPDATE = 1000 * 60 * 2;
public AppLocationService(Context context) {
locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);
}
public Location getLocation(String provider) {
if (locationManager.isProviderEnabled(provider)) {
locationManager.requestLocationUpdates(provider,MIN_TIME_FOR_UPDATE, MIN_DISTANCE_FOR_UPDATE, this);
if (locationManager != null) {
location = locationManager.getLastKnownLocation(provider);
return location;
}
}
return null;
}
@Override
public void onLocationChanged(Location location) {
}
@Override
public void onProviderDisabled(String provider) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public IBinder onBind(Intent arg0) {
return null;
}
}
最佳答案
您调用服务的方式不是使用服务的首选方式，我们从不在 BoradcastReceiver 中创建服务对象，因此您可以注册一个位置接收器，并根据您收到的更新值显示需要执行的 Toast手术。 我已经在下面更新了满足您要求的一种可能的解决方案。
此外，我仍然更愿意从广播接收器启动服务以获取位置，因为我们不应该对广播接收器进行大量操作，
public class SmsRemoteController extends BroadcastReceiver {
private static final int MODE_WORLD_READABLE = 1;
private String smsFirstCode;
private SharedPreferences myPrefs;
private Context contexts;
private String sendingNumber = "";
public static final int MIN_TIME_REQUEST = 5 * 1000;
public static final String ACTION_REFRESH_SCHEDULE_ALARM =
"org.mabna.order.ACTION_REFRESH_SCHEDULE_ALARM";
private static Context _context;
private static LocationManager locationManager;
private static LocationListener locationListener = new LocationListener() {
@Override
public void onStatusChanged(String provider, int status, Bundle extras){
try {
String strStatus = "";
switch (status) {
case GpsStatus.GPS_EVENT_FIRST_FIX:
strStatus = "GPS_EVENT_FIRST_FIX";
break;
case GpsStatus.GPS_EVENT_SATELLITE_STATUS:
strStatus = "GPS_EVENT_SATELLITE_STATUS";
break;
case GpsStatus.GPS_EVENT_STARTED:
strStatus = "GPS_EVENT_STARTED";
break;
case GpsStatus.GPS_EVENT_STOPPED:
strStatus = "GPS_EVENT_STOPPED";
break;
default:
strStatus = String.valueOf(status);
break;
}
Toast.makeText(_context, "Status: " + strStatus,
Toast.LENGTH_SHORT).show();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onProviderEnabled(String provider) {}
@Override
public void onProviderDisabled(String provider) {}
@Override
public void onLocationChanged(Location location) {
try {
Toast.makeText(_context, "***new location***",
Toast.LENGTH_SHORT).show();
} catch (Exception e) {
}
}
};
@Override
public void onReceive(Context context, Intent intent) {
contexts = context;
myPrefs = context.getSharedPreferences("myPrefs", MODE_WORLD_READABLE);
String smsMode = myPrefs.getString("state", "not");
if (smsMode.equals("ON")) {
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String smsBody = "";
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
sendingNumber += msgs[i].getOriginatingAddress();
smsBody = msgs[i].getMessageBody().toString();
}
// Toast.makeText(contexts,
// "number"+sendingNumber+"..body"+smsBody.toLowerCase(),
// Toast.LENGTH_SHORT).show();
if (smsBody.equals("locate")) {
_context = context;
locationManager = (LocationManager) context
.getSystemService(Context.LOCATION_SERVICE);
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
MIN_TIME_REQUEST, 5, locationListener);
Location gotLoc = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
double latitude = gotLoc.getLatitude();
double longitude = gotLoc.getLongitude();
Toast.makeText(contexts, "Mobile Location (NW): \nLatitude: " + latitude + "\nLongitude: " + longitude,
Toast.LENGTH_LONG).show();
} else {
Toast t = Toast.makeText(context, "please turn on GPS",
Toast.LENGTH_LONG);
t.setGravity(Gravity.CENTER, 0, 0);
t.show();
Intent settinsIntent = new Intent(
android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
settinsIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
_context.startActivity(settinsIntent);
}
}
// abortBroadcast();
}// end of onReceive()
}
} // end of the class
}
