While designing
rich layouts you might need to use two scrollview in your app.
Well ideally its not advised to use two scrollview in a view. So try to avoid it.

*Why this problem occurs ? : *
When you put two scrollview android just get confused
which scroll view is touched. So sometimes it gets unable to deliver touch
event.
But even if the requirement forces you to make such
layouts. Try this...
Say case is somewhat like this....
<ScrollView
android:id="@+id/parent_scroll"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="@drawable/dotted_bg"
android:focusableInTouchMode="false">
<LinearLayout />
<LinearLayout />
<LinearLayout >
<ScrollView
android:id="@+id/child_scroll"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/text_box_bg">
<TextView android:id="@+id/text_description"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="@color/gray"
android:textSize="12dip"
android:padding="5dip"
android:scrollbars="vertical"/>
</ScrollView>
</LinearLayout>
</ScrollView>
Step 1 : Provide unique id to both the scrollview.
Step 2 : get reference of that two scrollview in your activity.
Step 2 : get reference of that two scrollview in your activity.
parentScroll=(ScrollView)findViewById(R.id.parent_scroll);
childScroll=(ScrollView)findViewById(R.id.child_scroll);
Step 3: Now set touch listeners for both.
parentScroll.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
Log.v(TAG,"PARENT TOUCH");
findViewById(R.id.child_scroll).getParent().requestDisallowInterceptTouchEvent(false);
return false;
}
});
childScroll.setOnTouchListener(new
View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event)
{
Log.v(TAG,"CHILD TOUCH");
//
Disallow the touch request for parent scroll on touch of child view
v.getParent().requestDisallowInterceptTouchEvent(true);
return false;
}
});
Done ...
