how to close activity from event

I have the following code

public class DevCl开发者_开发问答ick implements OnItemClickListener {

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) { ... }

This is called from ListView from the activity. I want in that event that the caller activity will close. how can I get the activity from this event??

Thanks

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
        long arg3) { finish(); }

just only call finish function for closing activity.

Implement a custom constructor for your class an pass the activity as a parameter.

public class DevClick implements OnItemClickListener {

    private Activity mActivity;

    public DevClick(Activity activity){
        mAcitvity = activity;
    }

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) {
         mActivity.finish();
    }
}

you can create a constructor of your class DevClick with a argument of you caller activity then you can finish this activity from the event.

public DevClick (Context ctx){

   this.context = ctx;
}

Just call finish() whenever you want.
