Answer 1

There isn't anything wrong with the code you posted. If you have the fragment implemented correctly, it should be giving you a state of 2. Maybe you could post your activity and xml files. There error must be somewhere else.

Answer 2

Your fragment will only get re-used if you give the fragment an Id in the layout, change

<fragment
    android:name="ru.ee.TestFragment"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    />

to be

<fragment
    android:id="@+id/a_fragment"
    android:name="ru.ee.TestFragment"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    />
