廣播接收機中未調用的方法

Question

我想更新地圖，並從短信中獲取坐標。 接收方被調用，但是void refreshMap沒有被調用。 這是代碼：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.telephony.SmsMessage;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class MainActivity extends FragmentActivity implements LocationListener {

    GoogleMap googleMap;
    private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        IntentFilter filter = new IntentFilter(Intent.ACTION_DEFAULT);  
        filter.addAction(SMS_RECEIVED);
        filter.setPriority(1000);
        this.registerReceiver(this.smsReceiver, filter);

        // Getting reference to the SupportMapFragment of activity_main.xml
        SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

        // Getting GoogleMap object from the fragment
        googleMap = fm.getMap();

        // Enabling MyLocation Layer of Google Map
        googleMap.setMyLocationEnabled(true);               


         // Getting LocationManager object from System Service LOCATION_SERVICE
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        // Creating a criteria object to retrieve provider
        Criteria criteria = new Criteria();

        // Getting the name of the best provider
        String provider = locationManager.getBestProvider(criteria, true);

        // Getting Current Location
        Location location = locationManager.getLastKnownLocation(provider);

        if(location!=null){
                onLocationChanged(location);
        }

        locationManager.requestLocationUpdates(provider, 20000, 0, this);

    }


     private BroadcastReceiver smsReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) { 
                if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED"))
                                {                                               
                                    refreshMap();  //with the parsed coordinates from sms
                                }                       
                            }
                        }catch(Exception e){
//                                  Log.d("Exception caught",e.getMessage());
                        }
                    }
                }

            }
          };


    @Override
    public void onLocationChanged(Location location) {

        TextView tvLocation = (TextView) findViewById(R.id.tv_location);

        // Getting latitude of the current location
        double latitude = location.getLatitude();

        // Getting longitude of the current location
        double longitude = location.getLongitude();     

        // Creating a LatLng object for the current location
        LatLng latLng = new LatLng(latitude, longitude);

        // Showing the current location in Google Map
        googleMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));

        // Zoom in the Google Map
        googleMap.animateCamera(CameraUpdateFactory.zoomTo(15));

        // Setting latitude and longitude in the TextView tv_location
        tvLocation.setText("Latitude:" +  latitude  + ", Longitude:"+ longitude );      

    }




    @Override
    public void onProviderDisabled(String provider) {
        // TODO Auto-generated method stub      
    }

    @Override
    public void onProviderEnabled(String provider) {
        // TODO Auto-generated method stub      
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
        // TODO Auto-generated method stub      
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    public void refreshMap() {
        // TODO Auto-generated method stub
        Log.e("MAP","IS refreshing");  //NEVER CAlled
    }
}

我嘗試了幾種方法，但是從未調用過refreshMap（）。 任何幫助都會很棒。

Answer 1

我認為您需要在UI線程上調用refreshMap方法，如下所示：

     private BroadcastReceiver smsReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) { 
            if(intent.getAction().equals("android.provider.Telephony.SMS_RECEIVED"))
                            {    
                                MainActivity.this.runOnUiThread(new Runnable() {
                                    @Override
                                    public void run() {       
                                       refreshMap();  //with the parsed coordinates from sms
                                    }
                                });
                            }                       
                        }
                    }catch(Exception e){
                      Log.d("Exception caught",e.getMessage());
                    }
                }
            }

        }
      };
