how to get the hashtable object form a class to activity in android

I want开发者_如何学JAVA to get the hashtable object from non activity class to activity class an android

please reply to me

thanks

you can pass it through the intent object using extras. Something like this

after creating the intent in your non-activity class set the value using

objIntent.putExtra("keyName", "somevalue");

In the activity class access it like this

Bundle extras = getIntent().getExtras();
if(extras !=null)
{
String value = extras.getString("keyName");
}

EDIT:

 CityList extends Activity { 
    DBConnection server = new DBConnection(); 
    server.getDataValues(); 
    try { 
       Bundle extras = getIntent().getExtras(); 
       ArrayList<String> list = extras.getStringArrayList("city"); 
       System.out.println(list.get(0)); 
       System.out.println(list.get(1)); } 
    catch(Exception e) { Log.d(this.getClass(), e.getMessage()); } 
  } 

  class ServerConnection { 
    .... Intent intent = new Intent(this, CityList.class); 
    ArrayList<String> list = new ArrayList<String>(); 
    list.add("city_1"); 
    list.add("city_2"); 
    intent.putStringArrayListExtra("city", list); .. 
  }
