android:text = "Can I make it a function?"

Hi All, I am trying to make an app in android where the top left text will read Question 1 of 10 for example. The problem is I want it to update and not just say question 1 of 10 for all questions. I was thinking about a function that does: "Question" + int[i] + "of" + questions.length

How can I do that?

You don't have to set the text of that TextView in the xml layout file. You can set it dynamically with java code. Give the TextView an id in the xml file:

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/questionNumberTextView" />

Then in the java file get a reference to the TextView using findViewById:

TextView textView = (TextView) findViewById(R.id.questionNumberTextView);

Now, you can set the text:

textView.setText("Question " + questionNumber + " of" + questions.length);

assuming that you have an int variable questionNumber and an array called questions.
