i have a list view with 3 buttons it. the functionality of those button would be that when clicked that single view should expand in height to show a text box. i havent done any code in the CustomAdapter of that listview to provide any reference to it.
What you just described is an ExpandableListView.
EDIT: Also, you can have the TextView's visibility set to "gone" and just become visible when the button is clicked.

As Shown in image 1: I have listview with 2 items(half empty),and at the top i have one serch box I complete search functionality with custom adapter and Filterable but i want some other thing with this .they are
want to scroll listview with half empty(By Default it scrollable when Items more than area)
Search box should also scroll with listview.(As shown in 2 picture.)
listview should be scroll up to last item (Here last item is Item2 should always shown )and item at top should highlighted with different color.
Scrollview can have only one direct child. So if you want to put more than one view in a single scrollview, you should put all the views you need to scroll, inside single container view eg:-linear layout and put those views in that.
This is the situation;
I've a ListView with custom adapter. Each list item includes a button and a hidden TextView(Visibility=GONE). When we click on the button it displays the hidden textview.
Up to this it works perfectly.
Problem is, when the TextView is shown, the height of the ListView should increase accordingly.
I tried to adjust the height like..
list=(ListView)activity.findViewById(R.id.listView);
ViewGroup.LayoutParams l= lst.getLayoutParams();
l.height=l.height+150; //assuming the height of the TextView is 150
list.setLayoutParams(l);
But it doesn't work perfectly. I mean, height is increased, but it messes with the previous portion. Ie; Now when i click on the button, it doesn't show the corresponding TextView. Its shows TextView in some other ListItem.
Please help me to find a solution for this;
Thanks.
Unlike using View.Gone, set visibility as View.INVISIBLE. After clicking, textview should be set as View.VISIBLE. Gone means that TextView should not hold layout.
Lets look at View definations
Could you send listview, xml file.
I have a listview with custom listitem. I have bunch of textviews in Relative layout. And when I click on listitem it goes to different screen. Now I have added 3 buttons and toggle button to list item and I CAN NOT CLICK THE LIST ITEM. What am I missing :(
set focusable property of all the buttons to false and so that you can click on list and also touch event for all buttons will work
When the user clicks the row, the ListView will look for a widget implementing the Checkable interface. The RelativeLayout does not. An easy way to do that is simply to create your own CheckableRelativeLayout class. See http://www.marvinlabs.com/2010/10/custom-listview-ability-check-items/ for a full tutorial with code.
Also, the buttons and other items in your row layout should not be focusable. You can see other SO questions: Android Row becomes Unclickable with Button
I am using AdapterView to have Custom List. But my Xml layout not only
contains that List. It also have some other elements like TextBox,
labels, ImageButton at the top and bottom. so when i scroll it up
and animation starts it also draw elements on that Top Part(Which
contains ImageButton and other stuff). so can some one tell me how can
i remove it ? another issue is it do not have scrool bar. can some one
tell me how can i add scroll bar in it ?
for adding scroll bar to the listView add this attribute to your listview in the xml
android:scrollbars="vertical"
Check the following link. here i mentioned a complete code to use listview properly. Using this we can achieve any listview behavior. We can embed animation also.
For controlling list View Behavior ensure the getView Method of your list is generating the vew dynamically and as per your requirements . Each time a list get scrolled . The getView Method get called for all the element in the view. Do account all these things.

Hope this help :)
I jave a list of item (linearlayout inside a scrollview where i add buttons vertically to linearlayout dynamically from the java code ) ? i need when i click on one button the item moves up (scroll up) , to make the item at the first of the screen ??!
Well I never did that, but from the ListView reference it seems pretty clear that set setSelectionFromTop is what you are searching for.
