When I try to put my weather widget on the homescreen I want to give the user an option of choosing a city at that moment and the widget starts showing the weather for that city. For this I have made use of onEnabled method in Provider class.
So what I am doing here is just starting an activity to some preference class where I make use of string array to give the user the option to choose. And then OnSharedPreferenceChangeListener inside onEnabled again I am starting another activity with the url of city. This new acitvity class will handle the logic of weather at start up when I try to put the weather widget on the homecreen for the first time. So I am just trying to set some textFields in this new activity class so that they will appear in the widget when i put them on the screen, but I cant I dont know why its not being applied. Here is the code below of my AppWidgetProvider.
public class MyWeatherAppWidgetProvider extends AppWidgetProvider{
private String url;
@Override
public void onEnabled(Context context) {
// TODO Auto-generated method stub
super.onEnabled(context);
final Context this_context = context;
Intent intent = new Intent(context.getApplicationContext(), EditPrefs.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
OnSharedPreferenceChangeListener listener = new SharedPreferences.OnSharedPreferenceChangeListener() {
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
String key) {
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this_context);
url = prefs.getString("cities", "http://www.yr.no/place/Nepal/Bagmati/Kathmandu/forecast.xml");
System.out.println(url);
Intent intent = new Intent(this_context.getApplicationContext(), VaxjoWeather.class);
intent.putExtra("city", url);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this_context.startActivity(intent);
}
};
prefs.registerOnSharedPreferenceChangeListener(listener);
url = prefs.getString("cities", "http://www.yr.no/place/Nepal/Bagmati/Kathmandu/forecast.xml");
System.out.println(url);
}
