Hi all,
I'm trying to set vertical scrollbar programmatically. But get
following error stack on creation:

There is a very simple java code and xml layout:
public class BBB extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bbb);
int orient = getWindow().getWindowManager().getDefaultDisplay
().getOrientation();
if(orient== 1)
{
ScrollView viewMain = (ScrollView)findViewById
(R.id.layoutInputs1);
viewMain.setVerticalScrollBarEnabled(true);
}
}
}
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/layoutInputs1"
android:scrollbars="none"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:id="@+id/layoutInputs2"
>
<TextView
style="?android:attr/listSeparatorTextViewStyle"
android:text="test-test-test"
android:textColor="#FFFFFF"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</ScrollView>
Looks like I'm missing somethind...
Any ideas?
Thanks in advance,
Evgeny
