Question

Maybe this is the dumbest question ever, but I’m having a little trouble getting the actual Activity object.

My purpose:

In order to extract error handling from the different Activitys, I made a class ErrorHandler with static methods.

Such a method looks like this for example:

public class ErrorHandler {
    ...
    public static ErrorTuple checkPlaceInput(Activity activity){
        EditText edit = (EditText) activity.findViewById(R.id.et_nbge_place);
        if(edit.getText().toString().equals("") || edit.getText()==null){
            return new ErrorTuple(false, "Please enter a place!");
        }
        return new ErrorTuple(true, "everything is fine");
    }
}

In order to access the findViewById(...) method, I have to pass the Activity as parameter. As I read in different questions here, there is no other way to access Views from outside a running Activity. But, from the Activity itself, how can I access this object? Neither the Context nor the MyActivity.class are exactly the Activity object.

Answer 1

If you’re calling that method from an Activity, just do checkPlaceInput( this ).
