Given this code in Java for Android Studio, which gets the latitude and longitude for a location, modify it so that it also displays the address/location using the latitude and longitude. This is to be done using Geocoder. Do not use any other way to get the location.
package testing.gps_location;
import android.Manifest; import android.content.Intent; import android.content.pm.PackageManager; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Build; import android.os.Bundle; import android.provider.Settings; import android.support.annotation.NonNull; import android.support.annotation.Nullable; import android.support.v4.app.ActivityCompat; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.Button; import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private Button b; private TextView t; private LocationManager locationManager; private LocationListener listener;
@Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
t = (TextView) findViewById(R.id.textView); b = (Button) findViewById(R.id.button);
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
listener = new LocationListener() { @Override public void onLocationChanged(Location location) { t.append(" " + location.getLongitude() + " " + location.getLatitude()); }
@Override public void onStatusChanged(String s, int i, Bundle bundle) {
}
@Override public void onProviderEnabled(String s) {
}
@Override public void onProviderDisabled(String s) {
Intent i = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivity(i); } };
configure_button(); }
@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { switch (requestCode){ case 10: configure_button(); break; default: break; } }
void configure_button(){ // first check for permissions if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION,Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.INTERNET} ,10); } return; } // this code won't execute IF permissions are not allowed, because in the line above there is return statement. b.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { //noinspection MissingPermission locationManager.requestLocationUpdates("gps", 5000, 0, listener); } }); } }
