How to call a class from another activity? - class

Question

I want to call MainActivity class to another activity. This is my code for the MainActivity.java:
package com.blinkedup.geolocationchat;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.app.Activity;
import android.app.Service;
import android.view.Menu;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
TextView textView;
LocationManager locationManager;
MyLocationListener locationListener = new MyLocationListener();
Criteria criteria;
String bestProvider;
String listOfBestProviders;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
criteria = new Criteria();
textView = (TextView) findViewById(R.id.textView1);
criteria.setAccuracy(Criteria.ACCURACY_COARSE);
criteria.setPowerRequirement(Criteria.POWER_LOW);
criteria.setAltitudeRequired(false);
criteria.setBearingRequired(false);
criteria.setCostAllowed(true);
locationManager = (LocationManager) getSystemService(Service.LOCATION_SERVICE);
//locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
bestProvider = locationManager.getBestProvider(criteria, true);
Toast.makeText(getApplicationContext(), bestProvider, 3).show();
}
protected void onPause(){
super.onPause();
locationManager.removeUpdates(locationListener);
}
private class MyLocationListener implements LocationListener{
#Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
textView.setText("Latitude: " + location.getLatitude() +
"Longitude: " + location.getLongitude());
}
#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
}
}
}
In another activity I wanted to call the lat and long of the above code but don't want to rewrite the code to the activity. I just want to call it and display the result in another activity. please help. thanks

Answer 1

make your variable static and define it before onCreate() method use that variable in another activity by call like this.
YourMainActivity.yourstaticvariable
