I have a ListView over the whole screen of the application. To search for list items, I want an input field on the top of the ListView, but it should only become visible if the ListView is scrolled down (like the search field in the email application of the iPhone).
Because it is a ListView I can't create a cell with an input field (other field type like the other cells) in it.
I would be glad if someone can give a hint with which technic I can do it.
Thx.
I'd suppose to use material-design pattern with scrollable navigation bar. There is common template of an application for that purpose in Android Studio
I think you should have a look at SearchView widget :
https://developer.android.com/reference/android/widget/SearchView.html
You try using a SearchView with a ListView. Tutorial link :
http://www.coderzheaven.com/2013/06/01/create-searchview-filter-mode-listview-android/
If you want to hide this then probably make this action menu as invisible and invalidate the options menu and set the visibility true to make it visible on list scroll.
Add a layout above the listview to put in your search edit text (in a linear layout or a frame layout with padding for the list view).
Alternately you could use one of the Design Support Library components and it will be even more well integrated. Then call from your layout to filter the ListView adapter components, ideally with a text watcher or listener that is added to the edit text.

Hello I am new in Android, I am looking for create menu.
I am using this one popular menu guide.
http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/
Menu Aim :
At top Userinformation incase already logged in or Login/Register button if not login at bottom I use ListView. Is there anyway I can put first row as userinformation row and rest with menu item.
Please check attach screen source.
Thanks in advance.

For your requirement, you don't need ListView with mixed type rows. You can simply use header and footer view for ListView by calling list.addHeaderView(view) and list.addFooterView(view).
The whole top pannel can be your list header. Checkout this example

I have an activity with a RelativeLayout consisting of a ListView. This ListView is populated through a custom ListAdapter. The list displays a checkbox and text for each row.
So far, so good.
I want to implement something like the default android Gmail app, where if I checkbox-select an email, the titlebar of the application at the top changes and presents options relevant to the selection (such as delete, move, archive, etc). I am not sure what to look for in the Android documentation.
Do I just create some layout above the ListView and dynamically add elements(like delete row, etc) to it on a checkbox click? Any help is appreciated!
if you have used ActionBarSherlock then you can use Action mode menu to show various option to user when checkbox is selected from listview
or
you can try

I want to have an expandable menu, and when you expand a child item, then it will show some custom items, items of my choice, like a text input field or a checkbox (see the image below).
Now how can I achieve that? Can I achieve that using the Eclipse GUI builder? Or do I have to create methods where the data is loaded dynamically?
UPDATE:
So I do not only want text items as child elements, but all sorts of elements, like an input field or checkbox.
This tutorial works like charm

i also took code from here to make my custom expandable UI by implementing adapter
I am working on a UI where I have a list view. Each row has 2 information. One is Product name and the other is product ID stacked one over other. So each row has 2 lines of data.
What i want to do with this:
Once a user clicks on each row, it will further expand and show one input and one spinner. So it is basically for putting in Quantity and unit of measure.
Please let me know if this is achievable and if I can refer to some example.
What I need is more like
Taskos To Do List | Task List
https://play.google.com/store/apps/details?id=com.taskos&hl=en
All i need is that the category will not be expandable. Only the items will be expandable. All i need is an example of such app and then I can take it forward.
I think it could be done... you would need to put the extra widgets in your row layout, populate them and hide them upon list creation, then in your onListItemCLick you could unhide them.
Note I have no idea if this would work, but it seems reasonable that it might and it's what I would try and do to achieve the goal.
listView cannot be expanded. however you can use an expandablelistView
But the kind of functionality you want cannot be done this way(I guess.).
You can use
registerForContextMenu("your list View");
to register your list view
onCreateContextMenu
for the kind of action you want to be performed in your case its dialog with EditText and Spinner to have input from user
So, basically I have a custom View that contains a ListView with a custom Adapter that has the ability to read in information from the network (dumbed down HTML) and display it on a row by row basis.
All of this works, but I need the text that is read in to be parsed as HTML which contains links that can be tapped on and launched in browser.
I managed to do this by:
text.setText(Html.fromHtml(textBuffer), TextView.BufferType.SPANNABLE);
text.setMovementMethod(LinkMovementMethod.getInstance());
Works great, any links in the text are displayed as links and can be tapped.
This is a side effect of now making it so the rest of the rows in the ListView cannot be tapped (or tapped and held). Basically, all the rows are non-selectable now.
Is there any way to achieve both of what I need?
thanks!
Try setting text.setFocusable(false). By removing focus from the EditText, events will be passed onto the ListView or other items.
When you put an item that is focusable inside a ListView, it automatically makes the ListView not focusable. This is the behavior you are seeing.
To make them both focusable, I believe you can adjust the descendantFocusability property of the ListView.
See this question for a similar problem.
