Can't update my view method in android app

Question

I am making an app in which I need to update multiple textviews at once. For example:

//Just an example int
    int number = 0;
            public void updateViews(View view){

        TextView textview = (TextView) findViewById(R.id.my_textview);
    textView.setText("" + number);    
    }

Then let's sat that the number int changes, I need to update the updateViews method so that I don't have to manually update all of the TextViews at once. When I try to call something like:

updateViews();

it gives me an error. How can I solve this problem?

You need to provide the error message you're receiving. – Joseph Roque Jan 28 '16 at 18:43 — Joseph Roque, Jan 28 '16 at 18:43
@SG123 You need a logic? – Stanojkovic Jan 28 '16 at 18:44 — Stanojkovic, Jan 28 '16 at 18:44
It says "Update(View) cannot be applied to ()" – SG123 Jan 29 '16 at 21:23 — SG123, Jan 29 '16 at 21:23

OK so I figured this out. What I did was something like this:

public int number;

Public void add(View view){
number++;
Update();
return false;
}

Public void update(){
TextView textView = (TextView) findViewById(R.id.my_textview);
TextView.setText(""+number);

return false;
}

Trying using String.valueOf(number) instead of "" + number. – Ophitect Feb 02 '16 at 02:55
