Question

J'essaie de trouver un emplacement en utilisant le GPS mais le code suivant du snippet crée un problème. L'erreur s'affiche comme suit

La méthode makeText(Context, CharSequence, int) dans le type Toast n'est pas applicable.
pour les arguments (GeocodingMainActivity, String, int)

..........

private class MyLocationListener implements LocationListener {

 public void onLocationChanged(Location location) {
     String format = String.format( "New Location \n Longitude: %1$s \n Latitude: %2$s", location.getLongitude(), location.getLatitude());
    String message = format;
     Toast.makeText(GeocodingMainActivity.this, message, Toast.LENGTH_LONG).show();
 }

 public void onStatusChanged(String s, int i, Bundle b) 
 {Toast.makeText(GeocodingMainActivity.this, "Provider status changed",Toast.LENGTH_LONG).show();
 }

 public void onProviderDisabled(String s) {
     Toast.makeText(GeocodingMainActivity.this,"Provider disabled by the user. GPS turned off",Toast.LENGTH_LONG).show();

Answer 4

Remplacez votre MyLocationListener par le code ci-dessous. et passez le contexte lorsque vous utilisez votre MyLocationListener.

private class MyLocationListener implements LocationListener {
     private Activity mContext;
     public MyLocationListener(Activity context) {    
        this.mContext = context;
 }
 public void onLocationChanged(Location location) {
     String format = String.format( "New Location \n Longitude: %1$s \n Latitude: %2$s", location.getLongitude(), location.getLatitude());
     String message = format;
     Toast.makeText(mContext, message, Toast.LENGTH_LONG).show();
 }

 public void onStatusChanged(String s, int i, Bundle b) 
 {
      Toast.makeText(mContext, "Provider status changed",Toast.LENGTH_LONG).show();
 }

 public void onProviderDisabled(String s) {
     Toast.makeText(mContext,"Provider disabled by the user. GPS turned off",Toast.LENGTH_LONG).show();
 }

 public void onProviderEnabled(String s) {
     Toast.makeText(mContext,"Provider enabled by the user. GPS turned on",Toast.LENGTH_LONG).show();
 }
