TextView cuts off text when it is long enough

I have strange problem with TextView, it cuts off part of the text at the end. My layout looks like

<LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="top|center_horizontal"
        android:gravity="top|center_horizontal"
        android:orientation="vertical" >
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_gravity="top|center_horizontal"
            android:gravity="top|center_horizontal"
            android:orientation="horizontal"
            android:layout_weight="1"
            android:layout_marginBottom="5dp">
            <Button
                android:id="@+id/btnPreviousQuestion"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/selector_arrow_left"
                android:clickable="true"
                android:visibility="gone" >
            </Button>
            <TextView
                android:id="@+id/txtQuestion"
                style="@style/question_text"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:gravity="top|center_horizontal"
                android:layout_weight="1"
                 />
            <Button
                android:id="@+id/btnNextQuestion"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginRight="10dp"
                android:background="@drawable/selector_arrow_right"
                android:clickable="true" >
            </Button>
        </LinearLayout>
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="cent
