How to solve the error like java.lang.Throwable: setStateLocked?

I am developing an app. In it I'm using a listview. When I click on list item, it should go to next activity, i.e ProfileActivity2.java. It works fine, but in this ProfileActivty2 there is a button at the bottom and when I click on this button my app gets crashed and stopped in listview page. And shows the error java.lang.Throwable: setStateLocked in listview layout file i.e At setContentView. How do I solve this error?

//ProfileActivity2.java

    public class ProfileActivity2 extends AppCompatActivity {

        //Textview to show currently logged in user
        private TextView textView;
        private boolean loggedIn = false;

        EditText edname,edaddress;

        TextView tvsname, tvsprice;
        NumberPicker numberPicker;

context.startActivity(intent);

I think the error is at this line inside btn.setOnClickListener of getview block just use startActivity(intent);
