Question

In one class I call a function from another class which is on another .java file.

This is the function

public void make_a_call(String phonenumber) {
    Intent phone_call = new Intent(android.content.Intent.ACTION_CALL, Uri.parse("tel:"+phonenumber));
    startActivity(phone_call); 
}

The problem is this function requires it to be non static because of startActivity, but when I call this function from another class, it says that, to call it, this function needs to be static.

How can I fix this?

thanks.

Answer 1

The other class needs a reference to a context that will be used to start the activity. One solution is to pass a reference to the activity (the one that contains make_a_call) to the code in the other class. Another possibility (if the other class is a custom view, for instance), is for it to use getContext() to obtain a context and then modify make_a_call to be static but to accept a context as an argument:

public static void make_a_call(Context context, String phonenumber) {
    Intent phone_call = new Intent(android.content.Intent.ACTION_CALL, Uri.parse("tel:"+phonenumber));
    context.startActivity(phone_call);
}
