Android: Calling startActivity() from outside of an Activity context

Question

I have implemented a ListView in my Android application. I bind to this ListView using a custom subclass of the ArrayAdapter class. Inside the overridden ArrayAdapter.getView(...) method, I assign an OnClickListener. In the onClick(View v) method of the OnClickListener, I want to launch a new activity. I get the exception:

Calling startActivity() from outside of an Activity  context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

How can I get the context that the ListView (the current Activity) is working under?

Thanks for any help.

Answer 1

I think maybe you are implementing the OnClickListener in the wrong place - usually you should definitely implement an OnItemClickListener in your Activity and set it on the ListView instead, or you will get problems with your events...

Answer 2

Either cache context object via constructor in your adapter or get it from your view or as last resort add - FLAG_ACTIVITY_NEW_TASK flag to your intent

myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Edit - i would avoid setting flags as it will interfere with normal flow of event and history stack.
