setText to a variable

Question

I'm having trouble creating a simple app, I created a variable that changes when you click a button, but I would like to know how to set my TextView to that variable.

total is my TextView, and count is my variable.

I am trying total.setText(count);

I dont know how to tell it to just take the value of count and set the text to that.

Any help would be greatly appreciated.

Answer 1

First, you need to give your TextView an ID in the layout file:

<TextView
    <!-- existing code -->
    android:id="@+id/total">
</TextView>

Then use something like this to get the instance of the TextView and set the text:

TextView total = (TextView) findViewById(R.id.total);
total.setText(Integer.toString(count));
