Call an activity from non activity class

Question

I want to call an activity from a non activity class and base class send some arguments as bundle. But when I add the following code

 final Intent intent = new Intent(UserSettingsFragment.this, UserAccount.class);
  /*Sending some arguments*/ 
  Bundle bundle = new Bundle();
   bundle.putString("UserName",NAME);
   bundle.putString("Id", ID);
   intent.putExtras(bundle);
   this.startActivity(intent);`

eclipse shows the error

  The constructor `Intent(UserSettingsFragment, Class<UserAccount>) is undefined.

How can I solve this problem.

Is your `UserAccount` activity ? Please show your `UserAccount` class code. Also post your full logcat error. — GrIsHu, Dec 20 '13 at 08:37

Case 1

I have use other alternative in my case like pass Activity or Context in to constructor and using that context you can call your Next activity.

Case 2

I think you should use Interface and that callback will change your activity as per your response.
Write Callback method inside ABC interface and implement ABC in some other Java file which should extend Activity or Fragment Activity.
So that Override method will automatically call your event when some particular task will finish at some time.
I think this is easy and best way to call Intent from non extend Activity class.
See How to manage this with simple example here

As @Gooziec said:

You need to rewrite you code this way:

// If you are calling this for in a Fragment.
final Intent intent = new Intent(getActivity(), UserAccount.class);
/*Sending some arguments*/ 
Bundle bundle = new Bundle();
bundle.putString("UserName",NAME);
bundle.putString("Id", ID);
intent.putExtras(bundle);
this.startActivity(intent);`

The Intent constructor you are using requires a Context as first parameter. Please refer to the documentation.

1

use getActivity() instead of UserSettingsFragment.this.

I guess you try start another activity from fragment. If so, then you have to pass context of parent's Activity of the fragment to Intent constructor

Not sure why someone downvoted this answer. Given the incomplete question this is the closest assumption that we can make. Fragment class have a getActivity() method that you should replace UserSettingsFragment.this with – Mark Pazon Dec 20 '13 at 08:39
