Starting activity from a normal class

Hi,

does anyone know, if it's possible to start an activity within a normal class? What i want to do is, that an activity creates an instance of this class and then calls a function, which initiates a new activity. The own context of the calling activity should not be passed to the function.

I doubt its possible without passing the context or a handler etc.

ou can achieve this by having object of calling activity as a static memeber of itself.
here's the sample code

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public class MyCallingActivity extends Activity{
 
        static MyCallingActivity mObjAct;
 
        void onCreate(Bundle savedInstanceState)
 
        {
 
                mObjAct = this;
 
                MyNormalClass obj = new MyNormalClass();
 
                obj.someMethod();
 
        }
 
}
 
public class MyNormalClass
 
{
 
        void someMethod()
 
        {
 
                Intent i = new Intent(MyCallingActivity.mObjAct,NewActivity.class);
 
                MyCallingActivity.mObjAct.startActivity(i);
 
        }
 
}
