I'm having some problems with ScrollView
and an ImageView
.
What I want is:
I have an ImageView
set always at the top of the screen. Then, I have an ScrollView
where go all elements of the View
, and inside it I have another ImageView
which it is set at the bottom of the screen when previous elements don't fill screen (usually Big Screens), and it is set at the bottom of the ScrollView
when exists Scroll.
It is ok for some other Activities
I have, but I have some problems in one Activity
that has a FrameLayout
.
What I get is:
(See code below) When I set in the RelativeLayout
of the ImageView
(the one to stay at the bottom) height = "wrap_content"
:
Image
don't have its real size because it doesn't fit on the screen. To fit in it, Scroll
should appear. -> I don't know why it doesn't appear like in other Activities
. ImageView
appears at the bottom of the screen. As other elements don't fit on the screen, Scroll
appears inside FrameLayout
. When I set in the RelativeLayout
of the ImageView
(the one to stay at the bottom) height = "200dp"
(real height of image is smaller):
Image
doesn't appear. There isn't any Scroll
(it is not necessary because other elements are seen). Scrolls
. One inside FrameLayout
for elements, and another for seeing the ImageView
. Here is my code up to date:

Can you help me? Thanks in advance.
The solution I've found, looking at that question , is:
Create that function:
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(0, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
}
and call it with my ListView. Only one Scroll
(the one of ScrollView
) is seen and used.
