Answer 1

Write your XML code of text view with id as:

<TextText
    android:id="@+id/textview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

Than in your activity declare it before onCreate() method as:

public static TextView textview = (TextView) findViewByID(Your ID);

Than this will be accessible to all calsses.

Answer 2

You can use this everywhere:

TextView textview = (TextView) findViewByID(Your ID);
 textview = (TextView) findViewByID(Your ID);

Answer 3

Make it a singleton. Or just keep one public static reference.

public class MyReference {
    public static TextView myTextView = new TextView();
}

and then you can use it anywhere by calling MyReference.myTextView
