i'm using list view within a scrollview. To avoid the list view not scrollable, i need to het the height of list item and set the listview's height. How to get the list item height while using custom adapter?
Remove the parent scrollview... keep the listview as it is... and change height of listview to fill_parent then automatically as new items are populated in the list you can scroll through it to view ones that go out of the screen ... If by setting to fill_parent the ListView forces other views out of the screen manually set the Height by draging the edges in the graphical layout . Either ways no need to use the ScrollView
thanks to #Lalit for pointing out the hazards of setting a ListView to wrap_content

How could this scrolling behavior be accomplished?
Screenshot
To be specific, I need the wave effect to be shown whenever I try to scroll and reach the limit of a layout. Is there some property that I can tweak?
To get this wave effect, use any horizontally or vertically scrollable view as a container layout in your layout XML.
For example: ScrollView, HorizontalScrollView, NestedScrollView
List and Grid layouts like ListView, RecyclerView also has this scrolling effect.
I am using recylerview to display vertical list of data but when i open my app it is scrolled to last item automatically.How do i change default position of recyclerview?
i think you should set setStackFromEnd=false or setReverseLayout=false
And are you sure that you don't set scrollToPosition(list.size())?
I am using custom list view with base adapter. The width of row is longer than screen. But I am not getting horizontal scroll bar like automatic vertical scrollbar. Do I need to specify any extra attribute? I tried with putting listview in horizontal scroll view but still no success. How should I achieve this?
Thanx in advance.
You might just need to use android:layout_width="wrap_content" in your horizontal scroll. You should also show your XML layout in case it is just some other minor change, like having the list view inside the horizontal scroll view.
As a side note, you won't get a horizontal scroll bar but the views inside the horizontal scroll view will slide left/right if their width is wider than the screen.
I'm trying to add a scroll view inside another scroll view.
It should look like is this:
scroll view
linear layout
myprogramaticscroll view
myprogramticlinear layout
myprogramticbutton
end button
end layout
end scroll
end linear
end scroll
I'm trying to add scroll views inside of that. It goes in there, but I need to know how to set parameters correctly so I can see the whole button I have inside of my scroll view. I only see part of it, and I need to set the programatic linear layout and scroll view's width height and id. How do I do this? This is what I have so far:
//the layout I'm putting my scrollview/linearlayout/button in
LinearLayout l = (LinearLayout) findViewById(R.id.linearLayoutFavorites);
ScrollView scroll = new ScrollView(this);
LinearLayout nl = new LinearLayout(this);
ImageButton yourButton = new ImageButton(this);
nl.addView(yourButton);
scroll.addView(nl);
l.addView(scroll);
You CAN'T put a scroll view inside another scroll view, that behavior would be odd, and Android would not know how to handle your scroll on the views.
For setting layout parameters, take a look at ViewGroup.LayoutParams, there're actually quite a few subclasses of ViewGroup.LayoutParams, which are for setting layout parameters for different kinds of layouts.
You can use a Scrollview in an another Scrollview. But this is not suggestible. It will be an issue to both the user and android OS. It will leads to Memory issues and also touch issues while scrolling the views. If you are expecting the Two scrolls (Horizontal and Vertical) at a time, then it is preferble to go for TwoDSCrollView
If you want to set the Layoutparams you should look at ViewGroup.LayoutParams.
If you want to set width and height then no need to set the Layoutparams. You can get the existing params by using getLayoutParams() for the view and set width and height to that params.
If you want to place vertical in vertical scroll or horizontal in horizontal scrollview the you should set the height of the internal scrollview height to the actual height of the total childs.
I have the following question: I have a difficult layout that contain ListView. I need disable scrolling ability for ListView, because it's container (root Layout) have had ScrollView already, and I don't need a scrolls for ListView. I disable scrolls by android:scrollbars="none", but abilitity for scrolling would stay. I need that if ListView has 10 items that all items will be shown. How can I do it?
Can't you just use a LinearLayout with 10 elements instead of the ListView? It is not a good idea to have a ScrollView in another ScrollView.
Why do you still use the ListView? Create your own Layout for an item and load it several times (LayoutInflater, .addView(listItem)).
