This one has me stumped.
I need to call an activity method from within a custom layout class. The problem with this is that I don't know how to access the activity from within the layout.
public class ProfileView extends LinearLayout
{
TextView profileTitleTextView;
ImageView profileScreenImageButton;
boolean isEmpty;
ProfileData data;
String name;
public ProfileView(Context context, AttributeSet attrs, String name, final ProfileData profileData)
{
super(context, attrs);
......
......
}
//Heres where things get complicated
public void onClick(View v)
{
//Need to get the parent activity and call its method.
ProfileActivity x = (ProfileActivity) context;
x.activityMethod();
}
}
public class ProfileActivityActivity extends Activity
{
//In here I am creating multiple ProfileViews and adding them to the activity dynamically.
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.profile_activity_main);
}
public void addProfilesToThisView()
{
ProfileData tempPd = new tempPd(.....)
Context actvitiyContext = this.getApplicationContext();
//Profile view needs context, null, name and a profileData
ProfileView pv = new ProfileView(actvitiyContext, null, temp, tempPd);
profileLayout.addView(pv);
}
}
As you can see above, I am instantiating the profileView programatically and passing in the activityContext with it. 2 questions:
From your Activity
, just pass in this
as the Context
for your layout:
ProfileView pv = new ProfileView(this, null, temp, tempPd);
Afterwards you will have a Context
in the layout, but you will know it is actually your Activity
and you can cast it so that you have what you need:
Activity activity = (Activity) context;
