scrollview non funzionante

[allmystery]

Salve a tutti. lo scroolview l'ho sempre usato bene... ma preciso che l'ho sempre usato all'interno di un solo layout.
qui invece ho due layout , uno è quello principale e l'altro è quello in cui c'è lo scrollview... non sò se il problema possa essere davvero il layout, ma questa è l'unica differenza che c'è in tutte le altre volte che ho usato uno scrollview e mi è sempre funzionato...
ecco il codice incriminato:
<?xml version="1.0" encoding="utf-8"?><br /> <LinearLayout xmlns:android="http://schemas.android.com/<span class="forTooltip">apk</span>/res/android"<br /> android:orientation="vertical" android:gravity="right"<br /> android:layout_width="wrap_content" android:layout_height="fill_parent"<br /> android:id="@+id/mediaplayer_layout"><br /> <br /> <LinearLayout android:layout_width="fill_parent"<br /> android:layout_height="wrap_content" android:orientation="horizontal"<br /> android:id="@+id/LinearLayoutMedia"><br /> <br /> <Button android:id="@+id/playResourceButton"<br /> android:layout_height="wrap_content" android:layout_width="wrap_content"<br /> android:onClick="playResource" android:text="PLAY"></Button><br /> <Button android:id="@+id/st<span class="forTooltip">op</span>ResourceButton"<br /> android:layout_height="wrap_content" android:layout_width="wrap_content"<br /> android:onClick="st<span class="forTooltip">op</span>Resource" android:text="STOP"></Button><br /> <br /> <Button android:layout_height="wrap_content"<br /> android:layout_width="wrap_content" android:id="@+id/pauseResourceButton"<br /> android:onClick="pauseResource" android:text="PAUSE"><br /> </Button><br /> <br /> <br /> <br /> </LinearLayout><br /> <LinearLayout android:layout_width="fill_parent"<br /> android:layout_height="wrap_content" android:orientation="horizontal"<br /> android:id="@+id/LinearLayoutTesto"><br /> <ScrollView android:id="@+id/ScrollView01"<br /> android:layout_width="wrap_content" android:layout_height="wrap_content"><br /> <TextView android:id="@+id/storia" android:layout_width="wrap_content"<br /> android:layout_height="wrap_content" /><br /> </ScrollView><br /> </LinearLayout><br /> <TextView android:layout_width="fill_parent"<br /> android:layout_height="wrap_content" android:text=""<br /> android:layout_weight="1" /><br /> <LinearLayout android:orientation="horizontal"<br /> android:layout_width="fill_parent" android:layout_height="wrap_content"<br /> style="@android:style/ButtonBar" android:gravity="right"><br /> <br /> <Button android:text="procedi" android:id="@+id/ButtonProcedi"<br /> android:layout_width="wrap_content" android:layout_height="wrap_content"<br /> android:layout_weight="0" android:onClick="procedi"></Button><br /> </LinearLayout><br /> <br /> </LinearLayout><br />
