Question

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

Answer 1

A:

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");
}
